[0071] Preparation of the composition

[0072] The compositions of the present invention are generally prepared by conventional methods, such as methods for preparing topical compositions known in the art. The above-mentioned method typically involves mixing the ingredients to a relatively uniform state in one or more steps, which may or may not require conditions such as heating, cooling, and the use of vacuum. The composition is preferably prepared to optimize the stability (physical stability, chemical stability, light stability) and / or delivery of the active substance. This optimization may include an appropriate pH value (e.g., less than 7), the elimination of substances that can complex with the active substance and thus negatively affect stability or delivery (e.g., the elimination of impurity iron), and the use of methods to prevent the formation of complexes (if appropriate) Dispersant or dual-chamber packaging), using appropriate light stability methods (such as adding...

Abstract

Compositions useful for regulating the condition of mammalian keratinous tissue needing such treatments are provided. An exemplary composition comprises a safe and effective amount of glycyrrhizic acid and/or glycyrrhetinic acid; a safe and effective amount of an active selected from the group consisting of N-acyl amino acid compounds, hexamidine, cetyl pyridinium chloride, ergothioneine, and combinations thereof; and a dermatologically acceptable carrier.

Description

Invention field [0001] The present invention relates to personal care compositions containing skin and hair care actives. The above-mentioned composition can be used to adjust the keratinous tissue condition of mammals requiring the above-mentioned treatment, and is especially useful for lightening the skin. Background of the invention [0002] Many personal care products currently available to consumers aim to improve the health and physical appearance of keratinous tissues such as skin, hair, and nails. Most of these products involve delaying, minimizing or even eliminating skin wrinkles and histological changes. The changes are typically related to skin aging or environmental damage to human skin. However, there is still a need for cosmetic agents to prevent, delay, and / or treat uneven skin tone by acting as cosmetic agents that lighten the skin or reduce pigmentation. [0003] Mammal keratinous tissues, especially human skin and hair, suffer from many external and internal fa...
