It is also known as 1,2-dihydroxypentane, 1,2-pentanediol and pentane-1,2-diol.

### What are the properties of pentylene glycol?

Pentylene glycol is considered to be non-irritating and gentle, making it ideal for use in cosmetics for sensitive skin.

### What are the regulations on pentylene glycol?

For cosmetics manufacturers, it is vital to comply with the regulations in force to ensure the conformity of their products. In the European Union, Pentylene glycol is governed by Regulation (EC) No. 1223/2009 on cosmetic products.
