The liposomogenic UV absorbers according to the invention are preferably used as sunscreen agents in cosmetic preparations. They are capable of self-organization into bimolecular layers, and can thereby penetrate into the stratum corneum to a high extent and behave there in an extremely wash-resistant manner.

Description

Can form the UV absorption agent of liposome
The present invention relates to a kind of UV absorption agent that can form liposome, the preparation method of this compounds, and they in cosmetic formulations as the purposes of sun-screening agent.
Known wavelength is that the ultraviolet ray of 285-400nm can cause or quicken many different human body skins infringements, as erythema, and accelerated deterioration, phototoxicity and photoallergy etc.Be the localised protection human body skin, recommendation can prevent the compound of the cosmetic formulations form of UV radiation deleterious effect.
People further become known for chemical UV absorption agent itself in the cosmetic formulations of anti-UV and can only adhere on the skin deficiently or in the skin.So need to eliminate this deficiency as emulsion, gel or oil by the suitable prescription of exploitation.This prescription should allow UV protection material the long period to rest on the outer skin or in the outer skin.In addition, allow UV absorption agent hypersynchronous to enter stratum corneum, also make these compound long periods rest on the there simultaneously, this improved possibility is with the form of liposome packing (liposomal packaging) corresponding UV absorption agent to be coated on the skin.This method is described in, for example, and among WO-92.05761 and the WO-93.02659.
Unexpectedly, found a kind of UV chromophoric group and unitary compound of special chemical structure that on 285-400nm, has receptivity that contain, this structural unit make these compounds can be in bilayer self, this compound porous works in wash-resistant especially mode there to the stratum corneum depths.
