Title:
MOISTURIZING COMPOSITION FOR SIMULTANEOUS ACTING ON BOTH SURFACE AND DEEP SKIN LAYERS AND ITS USE
Document Type and Number:
Japanese Patent JP2595479
Kind Code:
B2
Abstract:
PURPOSE: To obtain the subject moisturizing composition capable of simultaneously moisturizing keratin layer, surface and deep skin layers, effectively useful for treating and caring for skin including scalp and nail.
CONSTITUTION: This composition comprises a first dispersion of lipid vesicles (A) capable of entering the deep layers of the skin and containing an active agent selected from polyols, sugars, proteins, vitamins (derivatives), ceramides, essential fatty acids and sterols for treating these deep layers and a second dispersion of lipid vesicles (B) capable of entering the surface layers of the skin and containing an active agent selected from polyols, nitrogen-containing carboxylic acid derivatives, keratolytic agents, inorganic salts and lipoamino acids for treating these surface layers. The vesicles (A) are capable of dispersing ALS in a keratin layer exceeding 1.10-7 cm2s-1 and are in a fluidized state at a room temperature and the lipid vesicles (B) are capable of dispersing ALS in a keratin layer not exceeding 1.10-7 cm2s-1 and are in a gel state at a room temperature.
