Problems solved by technology

This scheme mainly has two deficiencies: 1. The surfactant with strong hydrophilicity itself has a strong degreasing ability, which will stimulate the skin when used; 2. When using this method to make a microemulsion system, it needs high-speed stirring, Slowly add the pre-dispersed surfactant phase, which is inconvenient to operate

Embodiment 1

[0021] S1. Add 1 g of hydrolyzed jojoba esters to 2 g of glycerin, and stir for 15 min with a stirrer at a speed of 15 rpm;

[0022] S2. Add 2g of methylpropanediol to the mixed solution prepared in step S1, and stir for 15min at a speed of 15 rpm;

[0023] S3. Heat the mixed solution to 45°C, add 10g of 45°C purified water at a speed of 15 rpm, stir for 15min, cool down to 20°C, and keep warm for 10h to obtain the jojoba ester translucent system.

Embodiment 2

[0025] S1. Add 0.8 g of hydrolyzed jojoba esters to 1.6 g of glycerin, and stir for 5 min with a stirrer at a speed of 15 rpm;

[0026] S2. Add 1.6 g of methylpropanediol to the mixed solution prepared in step S1, and stir for 5 min at a speed of 15 rpm;

[0027] S3. Heat the mixed solution to 37°C, add 30g of 37°C pure water at 15 rpm, stir for 25min, cool down to 15°C, and keep warm for 8h to obtain a translucent jojoba ester system.

Embodiment 3

[0029] S1. Add 1.2 g of hydrolyzed jojoba esters to 2.4 g of glycerin, and stir for 25 min with a stirrer at a speed of 15 rpm;

Abstract

The invention provides a preparation process for a hydrolyzed jojoba ester semi-transparent system, in particular to a semi-transparent system which is formed by dissolving hydrolyzed jojoba esters into polyol, mixing a product with water under the heating condition, and performing stirring. The system can be directly added in a water agent product an the emulsified product as desired. In the preparation process, provided by the invention, the hydrolyzed jojoba esters are dissolved into the polyol, then the product is mixed with an aqueous solution without a clear water surfactant, irritationof the polyol to skin is greatly lowered after the polyol is dissolved into water as the polyol has the moisturizing effect self, and the semi-transparent system has very strong water-retaining property. The process provided by the invention is simple to operate and relatively low in energy consumption, can be finished under low-speed stirring, enables a product to form a target system at a room temperature after discharging and can well adapt to all semi-transparent or full-transparent water agent product systems.

Description

technical field [0001] The invention relates to the technical field of production of skin care products, in particular to a preparation process and application of a hydrolyzed jojoba ester translucent system. Background technique [0002] Jojoba esters are a kind of oil whose molecular structure is relatively close to the lipids of human skin itself. It is often used in skin care and moisturizing cosmetics to moisturize and nourish the skin; water agents represented by daily use lotion Skin care products can moisturize the stratum corneum and replenish moisture in the stratum corneum; the use of hydrolyzed jojoba esters in products such as lotion can well nourish and moisturize the skin. However, the raw materials of jojoba esters or hydrolyzed jojoba esters are oil-soluble substances and cannot be stably dissolved in water-based products. Most of the existing solutions are to solubilize jojoba ester or hydrolyzed jojoba ester in aqueous solution by adding a surfactant with...
