Deodorant made from nanoparticles to eliminate unpleasant odours These nanostructures have been used in different cosmetic products such as sunscreens, shampoos, anti-acne creams, and hair-styling materials. The discovery of fullerenes won a Nobel Prize and from which the nanotechnology field launched. The nail colour incorporated with nanoparticles developed by Nano Labs Corp. has been associated with different advantages like easy drying, shock resistance, elimination of cracks and scratches as well as easy application. Genotoxicity of AuNPs was reported as nonphototoxic, nongenotoxic, non-irritant and non-sensitizing according to OECD guidelines. These are considered as a 'nanosafe' carrier system that has negligible cytotoxicity and remarkable tolerance as these are made of biodegradable and physiological lipids. The attachments of different polymers with the nanomaterials produce coloured products. It was observed when the mode of application gets changed to aerosols. The nanoemulsions impart various properties to the cosmetics such as improvement in the shelf life of products and texture. The modifications of nanocapsules can also be achieved through the type of polymer and surfactants used. Nanotechnology-based approaches have been used in various oral care products like toothpaste, toothbrushes, mouthwashes, dental floss, etc so as to improve the efficacy of the product as compared to its traditional counterparts. It has been observed that there were remarkable effects on behavioural patterns upon exposure to ASTM-dispersed silver nanoparticles. size, shape, surface chemistry and charge), administered dosage and host immunity. The polymers attached with nanocapsules affect the dimensions of particles. Traces of different metal nanoparticles such as copper, iron, cobalt, nickel, chromium, cadmium, lead, arsenic, mercury, etc have been detected in cosmetics which pose a severe threat to human health. The balanced UVA and UVB protection can be achieved through the ZnO dispersions of small nanosized and large microsized particles. Thus, these nanocapsules are biocompatible in nature and are used in various deodorants. Also, silver nanoparticles present in the wastewater were found to show higher toxicity in comparison with TiO2 nanoparticles from the wastewater as well [188]. These nanocapsules have entrapped with fragrant molecules that make the continuous release of perfume. The cosmetic companies such as Dow Chemical Company, L'Oral, Revlon, and Unilever, have registered patents on dendrimer-dependent cosmetic preparations for various applications for skin, nail, and hair care products. This approach makes use of blending techniques using formulations having nanoparticles that establish the original skin colour initially followed by the desired skin colour. Nanotechnology: Tried but Untested. A comprehensive review of nanoparticles applications in the - Springer Risks and Benefits of Nanomaterials in Agriculture The extensive surge in the customers' demands has led to the development of formulations in cosmetics with better performance, retentions, attractive appearance, and more importantly safety [1, 2].

Dissolution of surfactant in diethyl ether followed by injection of solution through a 14-gauge needle into an aqueous solution of drug maintained at 60C. To name a few, immunogenicity, poor site-specific . Nonetheless, further studies are needed to understand the toxic effects of nanomaterials as the side-effect-free character of cosmetic products is a significant aspect. The results regarding the safety of silica nanoparticles are contentious, so deeper studies regarding the use of nanoparticles in cosmetics need to be conducted [36]. Metal-based nanoparticles have been exploited for their antioxidant properties thereby nullifying the effect of free radicals contributing to anti-aging. One disadvantage of nanoparticulate sunscreens is that they tend to clump together, making them difficult to apply. However, the risks, health and environmental hazards are caused due to exposure to nanoparticles which are not fully understood [175]. While latter includes vice versa as that of the divergent method in which the synthesis starts from the exterior part that ultimately becomes the outermost arm of the final dendrimer [4244]. These chemicals may cause irritation. Nanoparticles can cause lung damage. The guidance regarding the use of nanoparticles has been proposed by European Commission (EC) and Food and Drug Administration (FDA) by their own guidance for the utilization of nanoparticles in cosmetics. The Super Berry You Need To Know About: Schisandra Berry, The Best Vitamins & Nutrients For Radiant Skin, 5 Great Benefits of Baobab Oil for Your Skin. Therefore, antioxidants present in cosmetics can protect the skin. Table 1. It is found that AuNPs in concentration between 1 and 67 M/L are not cytotoxic to Hep3B (hepatocellular carcinoma) and Panc-1 (pancreatic epithelioid carcinoma) cells [27]. Reprinted with permission from [37]. 3. Similarly, anatase and rutile forms of TiO2 nanoparticles have shown reduced cell viability as well as a decrease in chlorophyll content in freshwater microalgae Chlorella sp. Later the second section highlights the pros of nanomaterials in cosmetics. Various types of nanoparticles have been used in cosmetic formulations. Different methods for the synthesis of lipid nanoparticles are reported such as using a high-pressure homogenization process. Silver nanoparticles have been observed to physically interact with bacteria resulting in pit formation thereby causing increased membrane permeability which further causes leakage of vital components ultimately resulting in cell death [184]. These nanoparticles are able to liberate the active components instead of deeper penetration through the skin. The use of silver nanoparticles in peel-off face mask formulation was also possible. Vitamin C, Why does our skin need a daily dose? The very first method of synthesis of liposomes was extrusion. This benefits the treatment of dandruff, itchy and oily scalp [33]. The nanoparticle drug delivery system is particular and utilizes . Method:Single-anonymous Ultrasound is another method for preparing lipid nanoparticles using high energy. There are several cosmetic companies that patented the usage of dendrimers in various products of skin, hair, nail [72].
