AI Technical Summary
Existing glycerol polyoxyethylene ether fatty acid ester synthesis technology fails to effectively control the hydrophilic-lipophilic balance of the product, resulting in the product being unstable in water or unable to effectively adhere to the skin or hair, affecting the skin moisturizing and hydrating effects, and domestic production relies on imports.
Using glycerol polyoxyethylene ether and natural oils in a molar ratio of 3:1 as raw materials, the reaction was carried out under the action of an alkaline catalyst. By controlling the reaction conditions such as temperature, time and catalyst dosage, and selecting appropriate EO addition number and catalyst type, glycerol polyoxyethylene ether fatty acid esters were prepared.
A glycerol polyoxyethylene ether fatty acid ester with a good hydrophilic-lipophilic balance was prepared, forming a stable nanomicelle system suitable for personal care products and cosmetics, achieving skin moisturizing and hydrating effects.
