I found several search results related to nails, nail polish, and nail care products. Here are some details on the products, their ingredients, and their positive and negative aspects:
-
Nail polish brands: Some nail polish brands are marketed as non-toxic and free of certain harmful chemicals, such as formaldehyde, toluene, dibutyl phthalate, formaldehyde resin, and camphor. However, some of these brands still contain other ingredients that may not be the safest, such as triphenyl phosphate. Some nail polish brands are also rated as highly hazardous by the EWG Skin Deep Cosmetic database. On the other hand, some nail polish brands are marketed as 10-free, meaning they are free of 10 of the most harmful leading polish ingredients. These brands are also marketed as having long-lasting wear. However, it can be tough to find exact details on what non-toxic means for these brands.
-
Nail care products: Nail care products sold in the United States must be safe for consumers when used according to directions on the label. Many nail products contain potentially harmful ingredients, but are allowed on the market because they are safe when used as directed. For example, some nail ingredients are harmful when swallowed, but not when used on the nails, because the nail is a barrier, which prevents absorption. Some nail products contain resins that form a strong coating on the nails, rather than hardening the nails themselves. There is evidence that some people may become allergic to certain nail product ingredients.
-
Artificial nails: Artificial nails are composed primarily of acrylic polymers and are made by reacting together acrylic monomers. Some artificial nails are made of silk, linen, paper, or fiberglass. Acrylic nails are applied by mixing a liquid with a powder and brushing the mixture onto the nails. Silk nails are fabric wraps that are glued in place to strengthen weak nails or help a cracked nail grow out. Some people may become allergic to certain artificial nail product ingredients.
In summary, nail polish brands and nail care products may contain potentially harmful ingredients, but are allowed on the market because they are safe when used as directed. Some nail products may cause allergic reactions in some people. Artificial nails are made of acrylic polymers or fabric wraps and may also cause allergic reactions in some people.
