Abstract

The invention provides sugar modified silicone oil and application thereof. The sugar-modified silicone oil is prepared from the following components in percentage by weight through amidation reaction, 15 to 25.8% of sugar lactone, 11.4 to 45% of amino polysiloxane, and the balance water; wherein the content of amino groups in the amino polysiloxane is 3.9-5.9 mmoL / g, the pH value of the sugar-modified silicone oil is 7, and the molar ratio of ester groups in the sugar lactone to amino groups in the amino polysiloxane is 1: 1. The sugar-modified silicone oil has good affinity with water and also has good affinity with the skin surface, a uniform protective film is more easily formed on the skin surface by the sugar-modified silicone oil, and the sugar-modified silicone oil has a good moisturizing effect. In addition, the molar ratio of the sugar lactone to the amino polysiloxane can be controlled by adjusting the ratio of the sugar lactone to the amino polysiloxane silica chain link, the variety of the sugar lactone is changed, and the dissolving performance and the moisturizing performance of the sugar lactone in water are further adjusted.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to a sugar-modified silicone oil and its application. Background technique [0002] Moisturizing cosmetics are playing an important role in improving and improving people's quality of life, and are also more and more favored by consumers. With the increasing demand for moisturizing cosmetics, its market prospects will become more and more broad, and its future development trend will revolve around the development of new and efficient moisturizing active agents and new evaluation methods for moisturizing efficacy. [0003] Traditional moisturizers mainly include glycerin, propylene glycol, butylene glycol, sorbitol, sodium pyrrolidone carboxylate, polyethylene glycol, and sodium lactate. They are all synthesized by chemical methods, except for sodium pyrrolidone carboxylate, others are still widely used cosmetic moisturizers. They all have the advantages of good moisturiz...
