Common Name(s): C30-45 olefin,c30-45 olefin,long-chain emollient,non-polar skin conditioner
CAS Number: N/a
DESCRIPTION
What It Does: Provides non-polar emollient conditioning with spreading value determined by chain length.
Why It's Used: Long-chain synthetic emollients provide precise performance engineering โ carbon chain length and branching determining spreading coefficient, viscosity, and wax character for targeted formulation outcomes.
How It Works: Long alkyl chain van der waals forces control viscosity and spreading โ chain length above c18 transitions from emollient oil to solid wax character.
Typically Found In: Skin care,colour cosmetics,anhydrous products
