Abstract

The present invention provides personal care compositions, containing tetrahydrocurcumin alone, or in combination with tetrahydromethoxycurcumin and / or tetrahydrobisdemethoxycurcumin are provided. Methods for regulating the condition of mammalian keratinous tissue by topically applying the personal care compositions are also provided.

Description

technical field [0001] The present invention relates to personal care compositions comprising skin and hair care actives such as tetrahydrocurcumin. The compositions described above are useful for regulating the condition of keratinous tissue in mammals in need of such treatment, especially for lightening the skin. Background of the invention [0002] Many personal care products currently available to consumers are aimed at improving the health and physical appearance of keratinous tissues such as skin, hair and nails. The vast majority of these products are concerned with delaying, minimizing or even eliminating skin wrinkling and histological changes typically associated with skin aging or environmental damage to human skin. However, there remains a need for cosmetic agents that prevent, delay and / or treat uneven skin tone by use as cosmetic agents that lighten the skin or reduce hyperpigmentation. [0003] Mammalian keratinous tissue, especially human skin and hair, is ...
