Problems solved by technology

However, the compatibility between water-based film formers and oil-based film-formers is poor, which makes it difficult to adjust the formula, and after the film-forming of acrylic film-formers, good elasticity and good skin-sticking effect are guaranteed, and film-forming Insufficient rigidity, when encountering acne-prone skin, it is necessary to add a large amount of fillers to ensure its concealing effect. The film-forming material itself cannot provide help for the improvement of concealing effects, and too much inorganic fillers increase the risk of pore clogging. risk
[0006] To sum up, the existing public technology cannot meet the requirements of concealer, moisturizing, long-lasting makeup, skin feeling, easy makeup removal, etc. Consumers will cause various skin problems during use

Abstract

The invention discloses BB cream containing a nonionic silicon-containing modified waterborne polyurethane dispersion. The BB cream comprises the following components: the nonionic silicon-containing modified waterborne polyurethane dispersion, pretreated pigment powder slurry, an emulsifier, a thickener, a polyhydric alcohol humectant, skin moistening grease, water and an optional adjuvant. The nonionic silicon-containing modified waterborne polyurethane dispersion is prepared from raw materials including a diisocyanate-terminated prepolymer, macromolecular siloxane and an amine chain extender through a reaction. The nonionic silicon-containing modified waterborne polyurethane dispersion is applied to a BB cream product, and the effects of concealing, good skin feeling, long makeup keeping time and easiness in makeup removal can be achieved at the same time.

Description

technical field [0001] The invention relates to the field of personal care, in particular to a BB cream, and more specifically to a nonionic silicon-containing modified aqueous polyurethane dispersion. Background technique [0002] BB cream, because it has the effects of foundation, sunscreen and isolation products, is more and more sought after by women who love beauty and has become a popular trend. [0003] BB cream (Blemish Blam) originated in Germany. It was originally designed by the Germans for patients receiving laser treatment. It has a thick texture and contains skin care and sunscreen ingredients, which can repair and regenerate damaged skin. It was later introduced by the Korean cosmetics industry and improved. After it was carried forward, it changed from a medical beauty product to a daily cosmetic beauty product, and evolved into a single product that integrates functions such as concealer, isolation, sunscreen, face repair, and base makeup. [0004] The exis...
