Cosmetic Grade Suspending Thickener Agent Liquid Carbomer SF-1
Product Description
Carbomer SF-2 is a type of carbomer, which is a high molecular weight polymer of acrylic acid. Carbomers are widely used in the cosmetic and pharmaceutical industries as thickening, gelling, and stabilizing agents. They are known for their ability to form clear gels and to stabilize emulsions.
1. Chemical Structure and Properties
Chemical Name: Polyacrylic acid
Molecular Weight: High molecular weight
Structure: Carbomers are cross-linked polymers of acrylic acid.
2.Physical Properties
Appearance: Typically appears as a white, fluffy powder or milky liquid.
Solubility: Soluble in water and forms a gel-like consistency when neutralized.
pH Sensitivity: The viscosity of carbomer gels is highly dependent on pH. They thicken at higher pH levels (usually around 6-7).
