Applications and Usages

It is used in cosmetics, cream, lotion, gel, toothpaste and other products.

1,3-butanediol molecular particles are very large, not easy to evaporate water, but can absorb more water, so it has moisturizing effect on the skin, without toxicity and irritation. It is very refreshing after adding it to skin care products. Skin whitening must first moisturize. As a combination of water molecules and hydrogen molecules, 1,3-butanediol can alleviate the problem of skin dryness and desalinate many fine lines and wrinkles on the skin in a short time, so it is a common ingredient in many anti wrinkle and whitening products.
