Problems solved by technology

This will have the following problems: 1. Gel-like phenomenon occurs during low-temperature storage, and discoloration is prone to occur during high-temperature storage; 2. The foaming ability of amino acid surfactants is inhibited; 3. The skin feel is affected by polymers during cleaning, It is sticky, dirty, and has a strong residual feeling; 4. The high price of polymers squeezes out the cost space of the formula

Embodiment 1

[0088] A liquid crystal thickener, prepared by the following method: disperse modified cornstarch into water, stir and disperse evenly, then add sodium cocoyl taurate, lauric acid, and myristic acid in sequence, and heat up to 60°C while stirring. ℃, add polyol, stir and react for 30 minutes, then cool down to room temperature; the amount of each component is calculated by mass percentage: sodium cocoyl taurate 1%, modified corn starch 30%, lauric acid 25% %, myristic acid 20%, water 20%, polyol 4%.

Embodiment 2

[0090] A liquid crystal thickener, prepared by the following method: disperse modified cornstarch into water, stir and disperse evenly, then add sodium cocoyl taurate, lauric acid, and myristic acid in sequence, and heat up to 80°C while stirring. ℃, add polyol, stir and react for 20 minutes, then cool down to room temperature; the amount of each component is calculated by mass percentage: 50% sodium cocoyl taurate, 20% modified corn starch, 10% lauric acid %, myristic acid 5%, water 10%, polyol 5%.

Embodiment 3

[0092] A liquid crystal thickener, prepared by the following method: disperse modified cornstarch into water, stir and disperse evenly, then add sodium cocoyl taurate, lauric acid and myristic acid in sequence, and heat up to 100 °C while stirring ℃, add polyol, stir and react for 10 minutes, then cool down to room temperature; the amount of each component is calculated by mass percentage: sodium cocoyl taurate 85%, modified corn starch 0.5%, lauric acid 0.5% %, myristic acid 1%, water 10%, polyol 3%.

Abstract

The invention discloses a liquid crystal thickener which is modified sodium cocoyl taurate in a surface activity solution system. The liquid crystal thickener can be applied to an amino acid system and is compounded with an amino acid surfactant to achieve the self-thickening purpose to manufacture semitransparent or opal cream type facial cleanser; at 0-50 DEG C, the cream type facial cleanser is free from obvious change in appearance and touch; the system added with the liquid crystal thickener has no drawing property or adhesion; the liquid crystal thickener further can be applied to a soap-based system, so as to effectively reduce unsmooth feeling in the soap base water rinsing process and tensioning feeling after drying and enhance the stability of the soap-based product stored at high temperature; the liquid crystal thickener can be applied to a liquid shampoo system in order to obviously strengthen the grease and silicon oil suspension stability of the system. The liquid crystal thickener can be applied to most of anionic surfactant systems, and a little affected by salt and pH value in the systems.

Description

technical field [0001] The invention relates to the technical field of cosmetic additives, in particular to a liquid crystal thickener and its preparation method and application. Background technique [0002] Cosmetics refer to smearing, spraying or other similar methods that are spread on any part of the human body surface, such as skin, hair, nails, lips and teeth, etc., to achieve cleaning, maintenance, beauty, modification and change of appearance, or to correct human body odor, maintain Chemical industrial products or fine chemical products for the purpose of good condition. With the improvement of people's material living standards, people pay more and more attention to the quality of cosmetics. [0003] In the 21st century, the cosmetics industry integrates and absorbs modern multidisciplinary high-tech achievements, improves the safety, functionality and environmental protection of cosmetics, develops new cosmetic raw materials, and adopts green and environmentally ...
