BI THK AVP (INCI name: Ammonium Acryloyldimethyltaurate/VP Copolymer) is a pre-neutralized thickener that can be used in aqueous gels and O/W systems. Compared with traditional carbomers, it has many advantages.

How to use
| No neutralization/soaking required, can be added at any step to adjust the viscosity during production. | Soaking is required before use. Viscosity can only be achieved after neutralization. |
Skin feel
| Super refreshing | Sticky
|
| UV light stability | Stable | Prolonged exposure to UV light may cause a decreased viscosity. |
| Shear stability | Stable | Prolonged shearing may cause a decreased viscosity. |
| Applicable pH range | Stable at pH 4-9. The viscosity remains basically unchanged. | The viscosity reaches its optimum value at pH 6-8. |
