Description
Technical Field
The invention relates to the technical field of cosmetics, in particular to a cosmetic makeup composition with a spatial three-dimensional structure.
Background
The epidermis of both humans and animals belongs to the stratum corneum protein. The composition for fixing the skin is one of cosmetic compositions, and can be used for fixing the skin and stabilizing different makeup. The skin make-up composition is primarily in the form of a make-up spray or a make-up lotion. The makeup mist and the makeup water have little difference in their compositions, but are different in their applications. A makeup spray is applied to the moist skin as an aid to model the makeup. In contrast, a make-up spray is sprayed onto dry, already patterned skin to secure the makeup. In addition to the make-up spray or make-up lotion, there are also forms of skin make-up gels.
The development of the prior art still stays in a stage that the pyrrolidone PVP is used as a main make-up fixing component, and the make-up fixing effect can be brought by a hard film of the pyrrolidone PVP.
The new patent technology forms a frame structure on the skin by macromolecular PVP and VPVA with about one hundred thousand daltons, then forms a framework of an interpenetrating network by polyurethane-10 with medium molecular weight and PVP and VPVA with large molecular weight with about one ten thousand daltons, and finally embeds polyalcohol and active ingredients on the framework of the space network to form an elastic three-dimensional space film. The whole film forming process is that with the volatilization of water, firstly, the macromolecular PVP and VPVA copolymer slowly stretches out from an agglomerated state through the acting force of a hydrogen bond to form a linear chain, then the acting force of the hydrogen bond is formed through NCO groups and CH groups on branched chains, and finally, a linear macromolecular chain is strung into a space net-shaped structure. Secondly, the polyurethane-10 with medium molecules also enables the polymer chain to slowly extend from an agglomerated state to be a linear chain, and then a linear molecular chain with different sizes is connected in series to form a compact space network structure through the acting force of hydrogen bonds formed by NCO groups and NH groups on the main chain. Finally, because the polyol of the small molecules contains a large number of hydroxyl groups, the hydroxyl groups can be dissociated in gaps of a space network structure formed by the polymer, so that a three-dimensional integrated three-dimensional space cross network of the large, medium and small molecules is formed.
