Not all Carbomer is the same Carbomer. A grade-by-grade reference for choosing between AM-940, AM-941, AM-980, AM-981, AM-U10, AM-U20, AM-U21, AM-2020, and AM-U30 — rheology, clarity, and what each grade is best for.

Carbomer gels only build their full network after neutralization — and once neutralized, they're sensitive to metal ions. Find out why a metal spoon can thin your gel, and why lab SOPs call for plastic or ceramic tools.

Carbomer clumping instead of forming a smooth gel is almost never a formula problem. Learn how expired or moisture-exposed raw material breaks the cross-linked network — and how a side-by-side hydration test confirms it.
