Polyquaternium-7 CAS26590-05-6

Product Description

Polyquaternium-7 is highly charged cationic copolymers developed to improve compatibility and clarity in anionic surfactant systems. Polyquaternium-7 is a clear, colorless to pale yellow liquid.Polyquaternium 7 acts as an excellent cationic conditioner for skin & hair. In cosmetics and personal care products, it is used in a wide variety of products.

Application

1. Used in hair conditioner, it can greatly improve the modifiability and conditioning of the hair. After washing the hair, it can make the hair shiny, soft and easy to comb, and make the hair have good wet and dry combing and anti-tangle properties. .
2. Used in skin care products, it is a very effective smoothing and lubricating agent. Used in hydroalcoholic tanning detergents, it can produce a non-sticky and non-greasy smooth residual film on the skin.
3. When used in shaving cream, it can produce rich, creamy, long-lasting foam, reduce shaving, and make the skin soft and smooth.
4. When used in foaming agent, it can quickly produce rich, thick and long-lasting foam, making the skin smooth without any oily film.
5. When this product is used in soap and other industries, it can reduce the expansion of soap substances in water, improve crack resistance and foaming performance, so that the product quality can be significantly improved.
6. In the formulation of shampoo products, it has good compatibility with commonly used surfactants, such as: AES, MES, 6501, OA, BS-12, APG, etc., without turbidity, precipitation and stratification.

Excellent Conditioning Performance

Polyquaternium-7 is renowned for imparting superior softness and manageability to hair and skin. Its cationic nature allows it to effectively neutralize static and improve the feel of formulations, making it a key ingredient in shampoos, conditioners, and skin care products. By forming a protective film, it reduces friction and enhances moisture retention for a smooth, hydrated finish.


Versatile Applications Across Industries

With strong compatibility to both anionic and nonionic surfactants, Polyquaternium-7 finds use in hair care, skin care, liquid soaps, lotions, and even wastewater treatment. Its ease of solubility and stable performance across a broad pH range contribute to its versatility for formulators and manufacturers alike.


Safe, Stable, and Sustainable

Polyquaternium-7 is considered non-toxic, non-irritant, and non-flammable as confirmed by standard toxicological tests. It is biodegradable, supporting sustainable formulation practices. The polymer remains stable under normal storage conditions and retains efficacy for up to 12 months when stored in tightly closed containers in cool, dry, well-ventilated areas.
