NAPHTHYL SALICYLATE Meaning and
Definition
-
Naphthyl salicylate is a chemical compound that is commonly used as an ingredient in various cosmetic and sunscreen products. It belongs to the salicylates group, which are organic esters derived from salicylic acid.
Specifically, naphthyl salicylate is derived from the condensation reaction between naphthol and salicylic acid. It is also known by its systematic name, methyl 2-hydroxybenzoate 1-naphthalenecarboxylate. The compound is composed of a naphthalene ring, which has a fused benzene ring structure, attached to a salicylate group.
Naphthyl salicylate is primarily used as a UV filter or sunscreen agent due to its ability to absorb and block certain types of ultraviolet (UV) radiation. It acts as a physical and chemical barrier, preventing the harmful UV rays from penetrating the skin and causing damage such as sunburn, premature aging, and increased risk of skin cancer.
In addition to its UV-filtering properties, naphthyl salicylate also possesses emollient properties, making it beneficial for skin moisturization and hydration. It is often included in cosmetic formulations such as lotions, creams, and sunscreens to offer both sun protection and skin nourishment.
It is important to note that naphthyl salicylate may cause skin irritation or allergic reactions in some individuals, especially those with sensitive skin. Therefore, it is advisable to conduct a patch test before using products containing naphthyl salicylate and to follow the instructions and precautions provided by manufacturers.
