摘要:
Cosmetic compositions are widely used to obtain certain benefits like e.g. anti-aging, skin lightening and moisturizing effect. These benefits are delivered by benefit agents (actives) like e.g. anti-oxidants, hyaluronic acid and resorcinol, pheynylethyl resorcinol and 4-alkyl substituted resorcinol. However, these actives have a certain shelf life beyond which they tend to degrade in terms of chemical activity and/or their color stability. The present invention discloses a novel process to prepare cosmetic compositions that improved color stability of resorcinol, pheynylethyl resorcinol and 4-alkyl substituted resorcinol and compositions comprising such actives when prepared as per said process.
