Functions

Product Name: Butyl Lactat
CAS No.:138-22-7

The chemical name of butyl lactate is alpha-hydroxybutyl propionate. It is a butyl ester derivative of lactic acid produced by the esterification of lactic acid and butanol produced by the fermentation of carbohydrates similar to sugar. It appears as a colorless, transparent liquid with a sweet cream and milk aroma. It is easily soluble in most organic solvents such as ethanol, ether, acetone, esters, etc. It is partially hydrolyzed when miscible with water. It is non-toxic and has good solubility.

Applications

Product Name: Butyl Lactat
CAS No.:138-22-7

1. Used as solvent for cellulose nitrate paint, printing ink, natural and synthetic resin. It is also used for dry lotion, adhesive, anti-crusting and spices. For high boiling solvent, for natural resin, synthetic resin, paint, printing ink.
2. Cosmetic solvents. Main solvent for cosmetics such as nail polish. A good solubility of the film forming agent for nitrocellulose is usually added to the solvent to adjust the viscosity and volatilization speed.
