1) Dipropylene glycol is the most ideal solvent for many flavors and fragrances and cosmetic varieties. This raw material has good water, oil and hydrocarbon co solubility, slight smell, little skin irritation and low toxicity. Isomers are evenly distributed and of excellent quality;
2) Dipropylene glycol can also be used as coupling agent and moisturizer in a variety of different cosmetic applications. In the field of perfume, the proportion of two propylene glycol is over 50%. In other application fields, the proportion of dipropylene glycol is generally less than 10% (weight). Some specific products include: hair curl, skin cleansing fluid (cold cream, shower gel, liquid soap and skin care) deodorant, face, hand and body skin care products, moisturizing skin care products and lipstick, etc.
