Silk 100A Multifunctional Solution to Formulate High Performance Conditioning Shampoos

CArBoPol® SIlk 100 PolyMEr

A Multifunctional Solution to Formulate High Performance Conditioning Shampoos

kEy BENEfItS

• Cost efficient solution to stabilize shampoo due to synergistic effects with salt and high suspending power

• Suited for challenging shampoo formulations (mild/low active systems) with pleasant flow and foam aesthetics

• Increases deposition of silicone and cationic polymer due to coacervation enhancement

• Enhances conditioning power and formulation flexibility with high performance conditioning polymers such as Merquat™ 2001 and Merquat™ 2003PR polymers

Combinations of Carbopol Silk 100 and Merquat 2003PR and Merquat 2001 polymer allow for:

• High silicone and cationic polymer deposition performance (small particle size silicone)

• Significant improvement in wet combing• Very good overall wet and dry sensory performance• Enhanced consumer experience with rich creamy shampoo

consistency and creamy dense foam
