What do nanoparticles do in mascara

Decomposition products from corneocytes and cornification cellular debris and stratum corneum lipids in the process of being shed are also present. This film provides a natural defense against pathogenic organisms but also attracts dirt and pollutants from the environment.

Sometimes the microorganisms present on the skin surface act on components of the surface film and create undesirable by-products, such as those resulting from the metabolism of compounds found in apocrine sweat that create body odor [ 52 ]. Thus, periodic cleansing to remove debris, dirt, and odor is essential to maintain skin health. Cleansing is also necessary to remove soil which may include bacteria from the skin surface that is acquired by incidental contact or by intentional application medications or makeup and other cosmetic products.

Silver nanoparticles are used as skin disinfectant and decontamination. Nano Cyclic Inc. Lip care is another promising class of cosmeceuticals. Different nanoparticles can be incorporated into lipstick and lip gloss which will soften or soothe the lips by preventing transepidermal water loss.

Korea Research Institute of Bioscience and Biotechnology holds a patent that described that it is possible to prepare pigments exhibiting wide range of colors using gold or silver nanoparticles by mixing in various compositional ratios and whose color can be maintained for a long period of time [ 54 ]. Silica nanoparticles used in lipsticks improve the homogenous distribution of pigments. Once applied, they prevent the pigments from migrating or bleeding into the fine line of lips [ 55 ].

Nanotechnology-based nail cosmeceuticals have various advantages over conventional products. A study revealed that nail paints having nanosized particles improve toughness, mar resistance, and impact resistance of the mammalian nails [ 56 ]. Nano Labs Corp. One of the new strategies which may have great potential in the cosmeceuticals is the incorporation of nanoparticles having antifungal activity like silver and metal oxide nanoparticles in nail polish to treat fungal toenail infections.

A review on various nanotechnology-based cosmeceutical products in the market and patents have been tabulated in Tables 1 and 2. Industrial use of nanoparticles has created new opportunities, but it also presents some risks and uncertainties. Increasing production and use of nanomaterials results in an increasing number of workers and consumers exposed to nanomaterials. This shows that there is greater need for information on their exposure routes.

Human routes of exposure to nanoparticles are inhalation, ingestion, and dermal routes [ 58 ]. Inhalation is the most common route of exposure to airborne nanoparticles [ 59 ].

Workers may inhale nanoparticles while production or consumers may inhale on the use of aerosolized cosmeceuticals deodorant, perfumes, etc. The deposition of nanoparticles in the respiratory system depends on their interactions with respiratory epithelium membrane. Nanoparticles may travel via the nasal nerves to the brain transsynaptic transport after inhalation through the olfactory epithelium and gain access to the nervous system [ 60 ].

Because of their size, these nanoparticles can easily gain access to the blood stream inhalation or skin and from there they are transported to the various organs [ 58 ]. Ingestion may occur from unintentional hand to mouth transfer of nanoparticles or from those cosmeceuticals that are applied near mouth or lips e.

Large fractions of nanoparticles rapidly pass out of the body after ingestion, but a small fraction may be taken up by the body which migrates into the different organs [ 61 ]. The other route of exposure of nanoparticles into the systemic circulation is dermal absorption. Majority of cosmeceuticals are applied to the skin. Three pathways of penetration across the skin have been identified: intercellular, transfollicular, and transcellular [ 62 ].

The skin is the largest organ of the body. Human skin is made up of three layers Figure 4 : the epidermis the outermost layer of skin , the dermis contains tough connective tissue, hair follicles, and sweat glands , and the hypodermis made up of fat and connective tissue. The epidermis is divided into several layers and its outermost layer, the stratum corneum, is responsible for the barrier function of the skin due to its lipophilicity and high cohesion between cells [ 63 ].

Passive routes by which a molecule can cross the stratum corneum are intercellular, transcellular, and appendageal routes Figure 5 [ 64 ]. A variety of cosmeceutical products having nanoparticles are in the market that are applied to the skin and concerns have been raised regarding the potential dangers which may occur on their skin penetration.

The transport of nanoparticles through the skin is related to the nature and physicochemical properties of the nanoparticles and vehicles, the nature of the substance, and the conditions of the skin [ 65 ].

Dermal absorption of nanoparticles does not occur readily but can take place under certain conditions. Although cosmetic products are meant to be used on normal skin, it is known that they are also applied on nonhealthy skin. In such conditions the barrier properties of skin may be impaired. Most of the study reported that nanoproducts applied to the skin only penetrate through hair follicular openings and skin pores, with minimal amount being found below the stratum corneum [ 66 ].

In a study on dermal absorption of ZnO nanoparticles from sunscreen applied to humans at the beach, Gulson et al. Whether the Zn was present as particles or soluble Zn ion was unknown at that stage [ 68 ]. The controversy has intensified, with numerous studies reporting that they do not cross the skin barrier, whilst others lead us to suspect new risks to humans, though without any of them providing a definitive answer.

A review of percutaneous absorption studies of TiO 2 and ZnO nanoparticles has been shown in Table 3 [ 70 — 77 ]. Nanoparticles from various cosmeceutical products applied on skin can have toxic effects if reaching to blood stream.

A research on toxicity of TiO 2 nanoparticles demonstrated that when nano-sized TiO 2 administered subcutaneously to pregnant mice, they transferred to the offspring and result in brain damage and reduced sperm production in male offspring [ 78 ]. Various researches have shown that TiO 2 nanoparticles can produce free radicals and cause cell toxicity in test tube studies, when exposed to UV light [ 79 , 80 ].

Studies have shown that cobalt-chromium nanoparticles If nanoparticles are inhaled and eaten accidentally or absorbed through skin, they could cause skin and lung damage and organ toxicity or can harm unborn children [ 81 ].

Silver nanoparticles are used in cosmeceuticals for their antimicrobial activity. Concentration of silver that is lethal for bacteria is also lethal for both keratinocytes and fibroblasts [ 82 ]. The cosmeceutical industry debates that consumer risks are low, as there is no evidence that nanoparticles from the product penetrate healthy, intact adult skin.

This is because there are numerous skin care products in the market which claim that the products counteract, retard, or control the aging process. FDA has stated such claims are illegal on cosmetic labeling. The regulation also requires that all marketed cosmetics and sunscreens using nanoparticles be individually tested for safety.

Cosmetic products containing nanomaterials must be notified by electronic means to the commission, providing data on identification, specification, quantity, toxicological profile, safety data, and foreseeable exposure conditions. Such notification must occur six months before a cosmetic product containing nanomaterials is placed on the market [ 84 ].

Growth of cosmeceutical industry is increasing day by day as the cosmeceuticals market is highly diversified, with products coming from major and small manufacturers and local companies around the world.

Nanotechnology represents the key technologies of the twenty-first century, offering excellent opportunities for both research and business. The rapid spread and commercialization of nanotechnology in cosmeceuticals have given rise to great technical and economic aspirations but also question about the emerging risks to health and safety of consumers.

Thus, cosmeceutical products based on nanotechnology should be designed and sold in a way that fully respects the health of consumers and the environment. The authors declare that there is no conflict of interests regarding the publication of this paper.

Such is obtainable from assessment of the cosmetic ingredients for acute, chronic, sub-chronic systemic toxicity, skin irritation and allergy, photo irritation and photoallergy. The other necessary data will be genotoxicity, fetal toxicity, carcinogenicity evaluation as well as harm to reproductive health. The Manufacturers: Workers in cosmetic production plants are constantly exposed to high concentrations of nanomaterials they work with through the inhalation route.

This is especially so if proper safeguard measures are not in place in such working environment, or are not followed since at the production area many tiny nanoparticles will be dispersed in the air. The Consumers: The consumers could be direct users of the product or those secondary users exposed as a result of contact or association with direct or primary users.

Simple actions as giving an embrace or a kiss could expose secondary users to nanoparticles in perfumes, skin care products or lipsticks. There are three possible points of entry of nanomaterials into consumers; Inhalation of sprayed products perfumes, fragrance , ingestion whether intentionally or unintentionally of lip and near-mouth products lip gloss, lip paints, mouth fresheners and via the skin through application of skin care products.

Inhaled nanoparticles due to their size can get into the functional unit of the respiratory tract the alveolus , with high affinity to interact with membrane of respiratory epithelium.

They likely will be absorbed through the olfactory epithelium, some quantity to nasal nerves into the brain while some others go into the circulatory system to the different organs [29]. Only small quantity of the ingested nanoparticle is reportedly absorbed into the circulatory system. The larger fraction leaves the gastrointestinal tract out of the body through fecal matter [6].

But for nanoparticles exposed to the skin, more is involved. The skin being the largest organ of the body is a primary route of exposure of cosmetic products especially by direct application. However when intact, its outermost layer serves as a functional seemingly impermeable barrier because it is lipophilic and has good cell cohesion. Although several works have been carried out to assess extent of penetration, if any, through the intact skin, there is no concrete evidence as to deeper layers of skin penetration by nanoparticles [15].

However in the presence of the following conditions, skin penetration has been documented:. At times stripping the upper skin surface with adhesives such as elastoplasters brings about the damage, removing the stratum corneum for entry of nanoparticles. The penetration profiles of the rutin nanocrystal gel on the porcine skin was carried out using tape stripping method and it was reported that the nanocrystals were found to penetrate deep to the horny layer of the skin [34].

These enhance cutaneous absorption of active cosmeceuticals. Water, alcohol, dimethyl-sulfoxide and some other surfactants have been employed to achieve dermal penetration. Many of such penetration enhancers are components of cosmetics. Follicular paths through hair follicle with its associated sebaceous gland, and even the sweat pores can be means of permeation of nano-sized lipids, niosomes or nanoparticles beyond the skin surface into the viable layers [50].

However, the quantity absorbable may likely be minimal, due to the appendages occupying only a small area on the skin and some of them being already filled up by sebum or sweat respectively flowing out in opposite direction to cosmetic ingredient applied for delivery into the skin.

From the foregoing, it can be inferred that the safety of nanocosmetics after dermal exposure depends on condition of skin especially if intact, as the skin barrier is strong enough to prevent permeation of copious quantity of nanoparticles applied to it.

But inhalation and ingestion equally can introduce nanoparticles into the blood stream. Beyond getting to the blood stream, an investigation into the level of damage or harm when in the system reveals the toxicity. TiO 2 inhaled was reported toxic because of size and agglomeration state [51]. Several works have compared nanoparticles of different metals to their micro and large-sized counterparts systematically with results indicating greater damage to organs exposed to nanosized materials [52] [53].

However, some have inferred that the toxicity seen in nanoparticles is not a function of just the size of the particles but likely because of the nature of nanoparticles involved that is insoluble nanoparticles are usually culpable [53].

Silver nanoparticles are used in cosmetics usually for their antimicrobial effect. It is important to note, however, that the concentration of nanosilver that is bactericidal can also be lethal for body cells such as the keratinocytes and fibroblasts [54].

However, disrupted skin can only allow silver nanoparticle penetration at 0. At this level, the nanoparticles is not seen to show any toxicity but smaller sizes of nanoparticle make for better skin penetration. It is because of these developments that toxicological considerations of cosmetics by some regulatory bodies now involve generating data from tests as to absorption, distribution, metabolism and excretion.

Generally, the stringent pre-market approvals necessitated for therapeutic products before release for public consumption is not applied to cosmetic products. One major reason for this occurrence could likely be the pre-emptive conclusion that nanoparticles of a material are no different from their large size counterparts in terms of properties. True, drugs and cosmetics are different however as stated in the outset, many cosmetics in the markets today elicit biological activities and are presented with penetration enhancers which can promote skin permeation of large quantities that could trigger a systemic effect.

Thus, those two reasons hindering pre-market approvals could stifle research and growth in scientific understanding of nanoparticles and their possible health risk. Without a doubt, then in line with the recommendations of the Royal Society of United Kingdom, given the evidence of serious nano-toxicity risks, nanoparticles should be treated as new chemicals requiring new safety assessments before being allowed for use in any consumer products. When implemented, this will imply that any nano-sized ingredients to be in consumer products should have appropriate detail, so that consumers have the chance to make an informed decision.

Manufacturers and marketers of cosmetic products are thus by law responsible for ensuring safety and proper labeling of their product as well as any risk directly related with the changed properties of nanomaterials as against their microscopic or larger molecule counterpart. The European commission EC has been proactive in this regard. This notification should be made available six months earlier before the product goes into the market, thus giving sufficient time for the Scientific Committee on Consumer Safety SCCS , of the commission make a risk assessment of the product for any concerns before being approved for market placement.

Any cosmetics with nanomaterial content must be authorized by the European Commission after opinion from the SCCS, which reviews submitted toxicological data prior to their use. As a way for a sound analysis of toxicity of ingredients in cosmetics, the International Cooperation on Cosmetics Regulation ICCR has produced recommendations for the use of alternatives to animal test methods in cosmetics safety evaluation and resolved that in risk assessment of any cosmetics, this should start with an appropriate appraisal of any existing information on the products while any sources of constituents will be characterized and documented [56].

Post-Market Surveillance is equally essential. Once a product is in the market, consumer use is monitored and scientific data continues to be collected. New safety methods are also considered as new scientific know-how evolves. As regulatory bodies of different nations monitor and standardize nanomaterials in cosmetics to be in the markets in their locality, sharing available information and possible challenges to acquiring them, if any, will also help to bridge the gap for a concerted and committed global effort at ensuring safety in the use of cosmetic products.

There is, however, the need for further investigation into the health implications of these skin applications rather than being complacent just in the commercially viable cosmetic space.

Although available knowledge in toxicity of nanoparticles is still adding up, it is essential. Regulatory bodies for cosmetic products will need to do more than providing applicable guidelines and supervision but also be proactive in screening to determine approval or not for new and existing nanosized ingredients used in cosmetics.

Such authorities should raise standards for manufacturers of cosmetics in appropriate product labeling and post marketing monitoring. International collaboration of regulatory agencies in sharing information on cosmetic ingredients and their impact on health is a must to ensure global coverage. Consumers, on observing any intolerant reaction of nanocosmetic products they use, should promptly make a report to appropriate authorities.

All thus have roles to play. From all indications, nanoparticles-contained cosmetics will continue to be relevant but it is important that relevance does not override health safety.

We as consumers should take a pragmatic approach in our cosmetic choices. The long-term consequences of such nanoparticles absorption are unknown. However, these certification bodies have assessed certain nanomaterials in cosmetic products as safe. For example, some nanomaterials, such as mineral derivatives titanium dioxide or zinc oxide are accepted in sunscreen products certified organic.

For example, Silica Silylate Nano. In New Zealand, the use of nano must be specified on the label of a product, says McNamara. If they truly are, just ask for proof. Nanoparticles do make certain skin care formulations more effective and more commonly, are known to increase the efficacy of sunscreens by improving UV protection in them. May 4,
