ABSTRACT:
Moisturizing units capable of moisturizing and improving flexibility, plasticity, and softness of keratinous matter, particularly mammalian skin, comprise liposomes, each having a matrix of a ternary lipid mixture of lecithin, dicetyl phosphate, and a sterol, and having cavities disposed within the liposome, the cavities containing a humectant such as sodium pyroglutamate, in an aqueous medium. The moisturizing liposomes function osmotically, serving as traps for water, which may be shared with the keratin constituents as required.
