[0029] Examples A1-A9 and Comparative Examples B1-B3: Preparation of an emulsifier composition forming a liquid crystal structure

[0030] According to the formula shown in Table 1, record the emulsifier, higher alcohol, and liquid oil as phase A, and deionized water and preservatives as phase B, heat phase A and phase B to 70-75°C respectively; stir in phase A Add phase B under normal circumstances, stir evenly until cooled to room temperature, and grind into powder (if it is paste, no need to grind). The performance test results of the emulsifier composition forming the liquid crystal structure are shown in Table 1.

Abstract

The invention discloses an emulsifier composition capable of producing liquid crystal structures as well as a preparation method and application thereof. The emulsifier composition capable of producing liquid crystal structure comprises the following ingredients in parts by weight: 5-20 parts of an emulsifier, 5-20 parts of higher alcohols, and 5-25 parts of liquid grease. By compounding the emulsifier of specific content with the higher alcohols of specific content and the liquid grease of specific content, the emulsifier composition capable of producing liquid crystal structures prepared bythe preparation method are capable of forming liquid crystal structures with uniform shape and particle size in large amount; moreover, the prepared liquid crystal structures are high in stability. Being applied in cosmetics, the emulsifier composition shows very good moisturizing property; moreover, the emulsifier is non-sticky when being applied onto the skin, as well as high in binding performance with the skin and good in stability. The preparation method of the emulsifier composition capable of producing liquid crystal structures is simple; and the prepared emulsifier composition is easyto store and transport, as well as convenient to use. Compared with single liquid crystal emulsifier, the emulsifier composition capable of producing liquid crystal structures prepared by the preparation method is low in melting point; so that, the emulsifier composition can be added and used at relatively low temperature. Thus, simple processes and wide application range are achieved; and energyconsumption is greatly saved during practical production.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to an emulsifier composition capable of producing a liquid crystal structure when added to cosmetics, a preparation method and application thereof. Background technique [0002] Liquid crystal is an intermediate phase between "liquid" and "solid". Liquid is a phase state with very good fluidity and continuity, while crystal is an anisotropic and birefringent phase state. The phase state between them is called "liquid crystal". The possible liquid crystal structures formed by surfactants mainly include hexagonal liquid crystals, cubic liquid crystals and lamellar liquid crystals. Lamellar liquid crystals are mainly used in skin care products. Lamellar liquid crystal has an oil / liquid crystal / water structure, which is very similar to the oil / stratum corneum / water structure of human skin. It is called "second stratum corneum". It can provide high-efficiency moisturizing and slow-release act...
