Sunscreen agents are commonly added in commercial cosmetic
products to protect skin from tanning and/or sunburn, due to
their excellent absorption capability at medium-wave ultraviolet
(280–320 nm, UVB) and long-wave ultraviolet range (320–400 nm,
UVA). Most of the sunscreen compounds are used safely for many
years. However, some chemicals such as oxybenzone (MW 228)
have been banned for cosmetics due to the carcinogenic toxicity of
oxybenzone [1]. Furthermore, in many countries such as China, the
type and amount of the sunscreen agents which can be added to
the cosmetics has been limited by Hygienic Standard for Cosmetics
of China. Thus, analytical techniques available for fast detection of
trace sunscreen agents in cream products are highly demanded.
