The various types of nanoparticles titanium dioxide (TiO2), zinc oxide (ZnO), silver, silicon dioxide, gold nanoparticles have been utilized in cosmetics [145150]. The coating of upconversion nanoparticles with polymers improves the penetration in the skin as shown in figure 2. This system makes an efficient and precise delivery of actives present in cosmetics. This kind of pollution is very dangerous for living organisms. These particles are biocompatible in nature and get degraded into CO2 and water. This is the main reason for the extensive use of zinc oxide and titanium dioxide nanoparticles in sunscreens. Scientists are primarily concerned about the toxicity, characterization and exposure pathways associated with Nano medicine that might pose a serious threat to the human beings and environment. However, the risks, health and environmental hazards are caused due to exposure to nanoparticles which are not fully understood [175]. The SLN being hydrophobic in nature, the particles are able to protect the skin from dehydration and to maintain the moisture of the skin. Microwave-assisted preparation of nano-hydroxyapatite for bone substitutes, wet chemical precipitation technique, ultrasound-assisted method, surfactant-assisted synthesis, and sol-gel technique is employed for the synthesis of nano-hydroxyapatite [97, 50, 51, 98, 99]. Gold nanoparticles have been employed in various cosmetic products such as skin wound disinfection, anti-inflammatory creams and lotions, face packs, and anti-aging creams. Nanotechnology could help to improve the sustainable production of crops for food or fuels. Moreover, further research focusing on newer ways to reduce nanoparticle toxicity should be undertaken which in turn would increase its applicability in the cosmetic industry. The safety of gold nanoparticles in the cosmetics was determined through various tests such as acute toxicity test, skin sensitization potential of AuNPs, irritation of the skin and eyes. For example, silver nanoparticles have been reported to show excellent antibacterial activities against Staphylococcus aureus and Escherichia coli. This may affect the different macromolecules of cells such as DNA and RNA [11]. The pomegranate juice contains different alkaloids and polyphenols. 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. Toxicity studies, the effect on human health and the environment of various nanomaterials used in the industry should be studied thoroughly.

However, there are some drawbacks related to their use in drug delivery, such as the limitation to maintain efficacy in the target organ once the magnetic field is removed from outside. The research on nanotechnology that followed, though, found that nanoparticles were damaging the environment by destroying useful microorganisms. There is a wide usage of nanoparticles in anti-aging products because of their carrier nature [151, 152]. The nanoemulsions are extensively used in sunscreen, deodorant, nail enamels, body lotions, hair conditioners and shampoos and hair serums [77]. Different methods for the synthesis of lipid nanoparticles are reported such as using a high-pressure homogenization process. In that process liposomes depending on the pore size of the filters employed and structurally modified to large unilamellar vesicles (LUV) or nanoliposomes [39, 58, 59]. Their research found that a deodorant made from nanoparticles - hundreds of times smaller than peach fuzz - eliminates odours up to twice as effectively as today's gold standard. Reprinted with permission from [37]. The usual shaped TiO2 and ZnO nanoparticles execute very useful applications in the cosmetic industry. Both hydrophilic and hydrophobic molecules can be delivered through the liposomes. Copyright (2019) from Elsevier. Here is why. These nanoparticles scatter UV light thereby preventing its harmful effect on the skin. A thorough study regarding safe doses of nanoparticles should be carried out so that the toxic effect of nanoparticles on the cells can be circumvented. Both zinc oxide and titanium dioxide nanoparticles are common ingredients of sunscreen. Therefore, the use of nanomaterials is a double-edged sword as the nanomaterials are useful for medical purposes, but result in far penetration of nanomaterials that exert an adverse health effect. For example, TiO2 nanoparticles coated with fatty acids like palmitoleic acid, oleic acid, palmitic acid, stearic acid, etc show a dramatic decrease in cytotoxicity as well as cell penetration in humans fibroblast skin cells as well as adenocarcinoma lung cells in comparison with bare TiO2 nanoparticles [183]. Once there, they can even alter cell DNA, thus causing serious health repercussions. However, research on nanoparticle toxicity needs to be considered. Suggest another disadvantage of these sunscreens. Brij Moudgil and colleagues note that consumers use a wide range of materials to battle undesirable odours in clothing, on pets, in rooms, and elsewhere. Depending upon the skin type and colour, nanoparticles used have been selected [121]. The only distinction between TiO2 and ZnO is TiO2 can be used for the UV B diminution while ZnO is a UV A safeguard to protect against aging caused owing to ultraviolet rays. The concerns regarding the usage of nanoparticles in cosmetics have been raised by various organizations such as World Health Organization (WHO), government as well as non-government organizations. Gold nanoparticles have been used for red or blue coloration; silver nanoparticles for yellowish coloration as well as gold-silver nanocomposites have been used for orange coloration [120]. Nanoemulsion synthesis involves a two-step process where a macroemulsion was first prepared and then converted to a nanoemulsion in a second step. Effect of TiO2 nanoparticles on penetration and cytotoxicity upon interaction with skin cells have been studied Evaluation of skin penetration of TiO2 nanoparticles using in vivo studies shows penetration through a dermal layer which further invades tissue causing pathological lesions in various organs thus causing a systemic response [181]. Nano-hydroxyapatite is mainly used in oral care products as well as cosmetic products. In the worst case, it can produce toxic effects. Chitosan nanoparticles have been used for entrapping -arbutin and - arbutin. These are considered as a 'nanosafe' carrier system that has negligible cytotoxicity and remarkable tolerance as these are made of biodegradable and physiological lipids. Nowadays production of different nanoparticles (NPs) with plausible biomedical benefits is tremendously increasing.
