Four-layer low-viscosity liquid cosmetic without perfluorinated compound

Abstract

The invention discloses a four-layer low-viscosity liquid cosmetic without perfluorinated compound, which comprises four layers of liquid phases, namely a liquid phase A, a liquid phase B, a liquid phase C and a liquid phase D; wherein the liquid phase A is a carbon chain alkane solvent with a mass percent of 5%-55%; the liquid phase B is polydimethylsiloxane with a mass percent of 5%-55% and derivatives of the polydimethylsiloxane; the liquid phase C is a water-alcohol solvent with a mass percent of 5%-55%; the liquid phase D is a special grease with a mass percent of 1%-35%. The invention adopts common cosmetic raw materials, and aims to provide a four-layer low-viscosity liquid cosmetic which has no physical separation between the layers but has clear layered interfaces between the layers. After shaking, the four layers can be mixed together, and after standing, a four-layer low-viscosity liquid cosmetic with clear layered four layers can be recovered, which has stable clear interfaces without oil drop hanging on the wall; and according to different dosage proportions of the raw materials, skin-care or skin-cleaning effects such as moisturizing, moistening and makeup removing can be provided.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a four-layer low-viscosity liquid cosmetic that does not contain perfluorinated compounds. Background technique [0002] The low-viscosity liquid cosmetics popular in the market are usually uniform, only a few low-viscosity liquid cosmetics have two layers, and there are very few low-viscosity liquid cosmetics with three layers, but no four layers Low viscosity liquid cosmetic products for sale. However, in the four-layer liquid cosmetics patents that have been applied for research, they all use perfluorinated organic compound solvents with relatively high density as important components. There are two small disadvantages in the application of perfluorinated compounds: [0003] One: Perfluorinated compounds are not easy to decompose naturally, so they were considered safe at first. After in-depth research, it was found that this was not the case. After it is absorbed by the human body...

Problems solved by technology

[0004] Two: Due to its low boiling point, perfluorinated compounds will quickly volatilize at a slightly higher ambient temperature. When preparing products containing this raw material, there are special requirements for the preparation process and ambient temperature. Controlling the stirring speed is cumbersome and inconvenient, and poses a great challenge to large-scale production
