Abstract

The invention discloses a water-resistant personal care oil-in-water emulsion composition, which comprises an emulsifier, at least one oily or fatty substance, a thickener and water, and is characterized in that: the emulsifier consists of components A and Composition of component B, wherein, component A is a phosphate ester surfactant, and component B is the mixture of one or more in the following nonionic emulsifiers: general formula is the alkyl glycosides of R4-O-(G1)a , the general formula is (R5COO)b-G2 sugar esters, and the general formula is (R6COO)c-(G3)d glycerin fatty acid esters or polyglycerol fatty acid esters. The invention provides an oil-in-water emulsion. When used as a personal care product, it can solve the greasy and residual problems caused by water-in-oil emulsions, film-forming polymers or special oils in the prior art, and bring refreshing Excellent feeling of use, and not easy to be washed off by water, especially suitable for making sunscreen cosmetics or foundation cosmetics.

Description

technical field [0001] The invention relates to a composition for personal care products, in particular to an oil-in-water emulsion, which is especially suitable for sunscreen or foundation products. Background technique [0002] Water resistance is known to be beneficial for personal care products, especially products such as sunscreen cosmetics or foundations. [0003] In the prior art, the method of preparing water-in-oil emulsion is usually used to meet the water resistance requirements of products such as sunscreen or foundation, that is, oil is used as the dispersion medium and water is used as the dispersed phase to form a water-in-oil emulsion. For example, Chinese invention patent publication CN1471903A discloses a water-in-oil type emulsion foundation, Chinese invention patent application CN1543331A discloses a water-in-oil emulsified sunscreen composition, etc. However, with the trend of more and more diversification of sunscreen components, it becomes more and m...
