Polyquaternium 7

Polyquaternium-7 is a quaternary polymeric salt derived from acrylamide and dimethyldiallylammonium chloride (DMDA), used for skin treatments and similar applications. It is a water-soluble acrylic copolymer designed to provide excellent compatibility with anionic systems.

Benefits

• It provides smoothness and reduces static.

Conditioning: This chemical product offers highly efficient conditioning, capable of improving hair manageability and combability, and also increasing hair strength.

Antistatic: This substance is capable of neutralizing the negative charge of shampoos and hair proteins. The positive ion charges, on the other hand, provide benefits to the skin and hair.

Film formation: This active ingredient is able to create a lightweight film on the hair strands, sealing the cuticles without increasing volume or leaving the hair looking heavy.

Where to apply

Polyquaternium-7, due to its high detangling and conditioning potential, is compatible with anionic surfactants. It is widely used in various cosmetic products, such as shampoos, hair sprays, hair mousse, conditioners, hair dyes, soaps, skin lotions, and contact lens solutions. Its applications include properties that promote detangling, conditioning, and film formation.

• Shampoos and hair/household cleaning formulations

Features

What is polyquaternium-7?

Polyquaternium-7 is a colorless, viscous liquid with a slight characteristic odor, exhibiting low acrylamide residue and 5% to 10% of active polymer. This active ingredient has antistatic and film-forming functions, being widely used in the cosmetic industry in different types of hair and skin care products. It stands out for its ability to create transparent formulations and for its effectiveness even at low concentrations, with the recommendation to add 2% to 10% directly to the formulas, depending on the desired characteristics and functions in the final product.

Cationic polymer (CAS 26590-05-6). Conditioning and depositing agent used in shampoos and hair/household cleaning formulations to provide smoothness and reduce static.
