Natural ingredients based cosmetics Content of selected fragrance sensitizers.

In the present study, we have investigated 42 cosmetic products based on natural ingredients for content of 11 fragrance substances; geraniol, hydroxycitronellal, eugenol, isoeugenol, cinnamic aldehyde, cinnamic alcohol, α-amylcinnamic aldehyde, citral, coumarin, dihydrocoumarin and α-hexylcinnamic aldehyde. The study revealed that the 91% (20/22) of the natural ingredients based perfumes contained 0.027%-7.706% of 1 to 7 of the target fragrances. Between 1 and 5 of the chemically defined synthetic constituents of fragrance mix were found in 82% (18/22) of the perfumes, 35% (7/20) of the other cosmetic products (shampoos, creams, tonics, etc.) were found to contain 0.003-0.0820% of 1 to 3 of the target fragrances. Relatively high concentrations of hydroxycitronellal, coumarin, cinnamic alcohol and αamyl cinnamic aldehyde were found in some of the investigated products. The detection of hydroxycitronellal and α-hexylconnamic aldehyde in some of the products demonstrates that artificial fragrances, i.e. compounds not yet regarded as natural substances, may be present in products claimed to be based on natural ingredients.
