l RapiThix A-60 and A-100 rheology modi- fiers are newly offered by International Specialty Products Inc. (ISP), Wayne, NJ. RapiThix products are easy to use, shear tolerant, shear thinning and effective at low use levels. RapiThix A-60 is a pre-neutralized, cross-linked, anionic thickening homopolymer. It does not require pre-swelling and can be used in O/W emulsions for fast viscosity build. RapiThix A-100 has a high polymer content and fully-active functionality for increased efficiency and greater formulation flexibility, especially in the preparation of oil-free products or products where additional oil is not acceptable.
