COSMEDIA® SP by BASF is an emulsifier and rheology modifier. It is a preservative-free, anionic acrylic homopolymer of sodium salt. It provides a special sensorial experience and a touch of exclusive elegance and luxury. It offers a silky, velvety and non-tacky after-feel in different types of skin care applications.
What is cosmedia SP?
Cosmedia® SPis an emulsifying polymer with stabilizing, thickening and emulsifying properties that gives formulators precise sensorial control, enabling them to achieve light textures, good spreadability, a fresh, pleasant skin feel and good tolerability. It also allows products to be marketed as “emulsifier-free”.
Is cosmedia SP a good emulsifier?
Cosmedia® SP is a very good polymeric emulsifier for giving consumers a special sensorial experience. Cosmedia® SP has an exceptional sensory profile, offering a silky, velvety and non-tacky after-feel in different types of applications.
What are the thickening properties of cosmedia®SP?
Cosmedia®SP Thickening Properties Formation of X-linked, spherical Polymer Particles Un-hydrated spherical polymer particle size = 0.5 µm Starting with monomer (e.g. Sodium Acrylate) solved in water and dispersed in a hydrophobic phase. Polymerisation + H 2 O Na+ CH 2CH C O O Hydrated polymer particle size = 5.0 µm 11 BASF Personal Care
What is the viscosity of cosmedia®SP?
Cosmedia®SP Viscosity Stability After 1 Month at 50°C Good stability under high temperature. 1% polymer (tel quel) Viscosity BKD RVT # 6.5 rpm (23°C) 18 BASF Personal Care Cosmedia®SP pH Influence Viscosity is optimum between 5 and 12.
What is the difference between cosmedia®sp and Benchmark B-D?
Products in emulsion (Benchmark B-D) are less efficient than powder (Benchmark A and Cosmedia®SP), require higher % to reach same viscosity range. Cosmedia®SP is a cost efficient alternative. 1% polymer (tel quel) Viscosity BKD RVT # 6.5 rpm (23°C) 15 BASF Personal Care Cosmedia®SP Compatibility with Polar Solvent as Ethanol
