Question 5

How does Oryza Sativa Cera  Bran Wax) work chemically?

Accepted Answer

The molecule profile is a natural wax mixture dominated by long-chain fatty acid esters, fatty alcohols, acids, and minor unsaponifiables, giving it a high melting range around 75 to 85°C. Typical use levels are about 1 to 10% in sticks and balms, lower in emulsions, and it should be fully melted into the oil phase before cooling to manage crystallization and texture.
