Embodiment 1

[0051] The preparation method of water-based polyglycerol fruit acid ester compound, the steps are as follows:

[0052] Add 1.5g of sodium hydroxide to 3.5g of water to make a 30% sodium hydroxide solution, and add it to 100g of triglycerin. Under stirring, the temperature of the system was raised to 125° C., and stirring was continued for 1 hour. Then, under the condition of -0.06MPa, the 3.5g of water introduced during the addition of sodium hydroxide solution in the system was distilled off under reduced pressure.

[0053] Then, the temperature of the reaction system was lowered to 5-10°C, and under stirring, 120 g of epichlorohydrin was slowly added through the dropping funnel, during which the temperature of the reaction solution was kept between 5-10°C, and the dropping time was 3 hours. After the dropwise addition was complete, stirring was continued for 1 hour.

Embodiment 2

[0057] The preparation method of water-based polyglycerol fruit acid ester compound, the steps are as follows:

[0058] Add 1.6g of sodium hydroxide to 3.8g of water to make a 29.5% sodium hydroxide solution, and add it to 100g of triglycerin. Under stirring, the temperature of the system was raised to 125° C., and stirring was continued for 1 hour. Then, under the condition of -0.06MPa, 3.8g of water introduced during the addition of sodium hydroxide solution in the system was distilled off under reduced pressure.

[0059] Then, the temperature of the reaction system was lowered to 5-10°C, and under stirring, 120 g of epichlorohydrin was slowly added through the dropping funnel, during which the temperature of the reaction solution was kept between 5-10°C, and the dropping time was 3 hours. After the dropwise addition was complete, stirring was continued for 1 hour.

Abstract

The invention relates to a water-based polyglycerol fruit acid ester compound and a preparation method thereof. The water-based polyglycerol fruit acid ester compound has both fruit acid and polyglycerol structures, and not only has good biocompatibility, modifiability and Biodegradable, and has a large number of free carboxyl groups, as well as polyglycerol's polyhydroxyl structure, has excellent properties in terms of moisturizing, emulsification, stability, and salt resistance; the preparation method adopts the reaction of polyglycerin and epichlorohydrin to obtain epoxy Unit polyglycerin, and then react with polycarboxylated fruit acid to obtain free carboxyl units and more carboxyl groups, which greatly improves the moisture retention, emulsification and salt resistance of the product. It is used in skin care products, and at the same time Makes the skin very smooth.

Description

Technical field: [0001] The invention relates to a water-based polyglycerol fruit acid ester compound and a preparation method thereof, belonging to the technical field of chemical synthesis. Background technique: [0002] Fruit acid is a variety of organic acids extracted from fruits, mainly including lactic acid, citric acid, malic acid, tartaric acid, etc. Among them, malic acid and tartaric acid are fruit acids containing two carboxyl groups, and citric acid is fruit acids containing three carboxyl groups. fruit acid. As an important class of organic acids, fruit acids are widely used in chemical, food and pharmaceutical industries and other fields. When used in cosmetics, fruit acid can weaken the adhesion of keratinocytes at low concentrations and promote skin metabolism; at medium concentrations, it can improve skin moisturizing performance and increase the water content of glial cells and superficial dermis; at high concentrations, the penetrating power Very strong...
