Cosmetic Grade Raw Material Polyquaternium-7 cas 26590-05-6 For Hair Care
Products Description
Polyquaternium-7 is highly charged cationic copolymers developed to improve compatibility and clarity in anionic surfactant systems. These copolymers are recommended to improve wet and dry properties of hair care products, and to enhance feel in skin care products. Acts as an anti-static agent and film former. It strengthens and stablizes the foam and delivers luster, soft and silky feel. Polyquaternium-7 makes hair easy to comb and keep the frizzle firm during hair styling process.
Polyquaternium-7 is used as a cationic conditioner for shampoos, shower gels, shaving lotions, styling water, etc. Industrially,it treats municipal wastewater and is also widely used in the paper industry.
Physical and chemical properties
- Appearance: usually colorless to light yellow transparent viscous liquid, this appearance makes it easy to mix and disperse in a variety of product formulations.
- solubility: It has good water solubility and can quickly dissolve in water to form a uniform solution, which ensures its stable existence and effective role in water-based system products.
- Stability: shows good stability under conventional storage and use conditions. However, contact with substances such as strong oxidants and anionic surfactants should be avoided to avoid chemical reactions and affect their properties.
- Charge characteristics: Because the molecular structure contains quaternary ammonium salt cationic groups, polyquaternary ammonium salt-7 has a positive charge. This positive charge characteristic enables it to generate electrostatic attraction with negatively charged substances (such as hair surface, skin cuticle, etc.), thus achieving excellent adsorption and adhesion properties.

Function:
- Regulating effect: In hair care products, polyquaternium-7 can adsorb onto the surface of hair, forming a protective film that effectively improves hair combing, reduces static electricity generation, makes hair softer and smoother, and enhances hair glossiness. In skin care products, it can form a moisturizing film on the surface of the skin, helping the skin retain moisture and make it feel soft and moisturized.
- Antistatic effect: With its positive charge characteristic, polyquaternium-7 can neutralize the negative charge on the surface of objects, effectively reducing the generation of static electricity. In industries such as textiles and plastics, it is often used as an anti-static agent to improve the performance and comfort of products.
- Thickening effect: In some cosmetics and detergent formulations, polyquaternium-7 can increase the viscosity of the product, improve its rheological properties, and give it better stability and texture. It can regulate the fluidity and spreadability of the product, making it easier to use and apply evenly.
- Sterilization and anti-corrosion effects: Polyquaternium-7 has a certain inhibitory and bactericidal effect on some bacteria, fungi and other microorganisms, so it can play an auxiliary anti-corrosion role in some products, extending the shelf life of the products.
Applications
- Personal care products: widely used in shampoo, conditioner, hair gel, mousse, shower gel, moisturizer and other products. In shampoo, it can improve the cleaning effect and combing of hair; In hair conditioner, it can enhance the softness and glossiness of hair; In shower gel and moisturizer, they can moisturize and regulate the skin.
- Textile printing and dyeing industry: used as anti-static agents and softeners, it can improve the anti-static performance of textiles, make the fabric feel soft and smooth, and also improve the dyeing performance of fabrics, increasing dyeing uniformity.
- Paper industry: Adding it to paper coatings and paper processing agents can improve the strength, water resistance, and anti-static properties of paper, as well as enhance its surface properties and printability.
- In the field of water treatment:as a cationic flocculant, polyquaternium-7 can undergo flocculation with negatively charged suspended particles, colloids, and other substances in water, causing them to precipitate and separate, thereby achieving the goal of purifying water quality
safety
Polyquaternium-7 is safe for human use under normal conditions. Its usage concentration in cosmetics is usually low, and after extensive safety evaluation and practical application verification, it generally does not cause irritation to the skin and eyes. However, for a very small number of people with allergies, it may cause allergic reactions. When using products containing polyquaternium-7, if any discomfort symptoms occur, the use should be immediately stopped and professional assistance sought. At the same time, relevant safety operating procedures should be followed during production and use to avoid contact with high concentration products.
