What it is
Polyquaternium-51 is a copolymer of butyl methacrylate and a methacrylate monomer carrying a phosphorylcholine group (an inner salt with both a positive and a negative charge). CosIng lists it as a film-forming and skin-conditioning ingredient.
Where it is used
Found in creams, serums, eye products, lotions and hair care products.
Limits of interpretation
The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.
Despite the polyquaternium name, it is not a typical cationic conditioning polymer; the label does not show its molecular weight.
Functions
- Film forming
- Producing (upon application) a continuous film on the skin, hair or nails.
- Skin conditioning
- Maintaining the skin in good condition.
