Overview of Whole Polyquaternium-7 / Poly (DMDAAC/AM)
Amphoteric surfactants are a unique class of surface-active agents that possess both cationic and anionic properties, depending on the pH of the system they are in. They contain both a positively charged group (like a quaternary ammonium salt) and a negatively charged group (such as a carboxylate or sulfonate), which can ionize depending on the surrounding conditions. This dual nature grants them exceptional versatility, making them effective in a wide range of pH environments and compatible with other surfactant types. They are known for their mildness and excellent dermatological compatibility, rendering them particularly suitable for personal care applications.
Features of Whole Polyquaternium-7 / Poly (DMDAAC/AM)
-
pH Responsiveness: Their charge varies with pH, becoming cationic in acidic conditions and anionic in alkaline, with a zwitterionic (neutral) state at the isoelectric point.
-
Mildness: Known for being gentle on skin and eyes, making them ideal for sensitive applications like baby care and personal hygiene products.
-
Foaming Properties: Can generate rich, stable foam even in hard water conditions, enhancing their use in cleaning products.
-
Emulsification: Efficient emulsifiers capable of forming both oil-in-water (O/W) and water-in-oil (W/O) emulsions, depending on the formulation and pH.
-
Compatibility: Because they have both anionic and cationic properties, they are compatible with other types of surfactants and can work synergistically to enhance cleaning effects.
-
Biodegradability: Many amphoteric surfactants are readily biodegradable, contributing to their environmentally friendly profile.

Specification of Whole Polyquaternium-7 / Poly (DMDAAC/AM)
Polyquaternium-7 / Poly (DMDAAC/AM) is a synthetic copolymer widely used in personal care products for its conditioning and stabilizing properties. The chemical structure combines dimethyldiallyl ammonium chloride (DMDAAC) and acrylamide (AM). This creates a positively charged polymer that interacts effectively with negatively charged surfaces like hair and skin.
The product typically appears as a clear to slightly hazy viscous liquid. It is soluble in water, making it easy to blend into formulations. The pH range is usually between 5.0 and 7.0, ensuring compatibility with most cosmetic ingredients. The viscosity varies based on concentration, often falling between 500 and 5000 centipoise at 25°C.
Polyquaternium-7 functions primarily as an antistatic agent and film-forming polymer. It binds to keratin in hair, reducing frizz and improving manageability. In skincare, it enhances the texture of lotions and creams by providing a smooth, silky feel. The polymer’s cationic nature helps it adhere to surfaces, increasing the longevity of other active ingredients.
This ingredient is compatible with a wide range of surfactants, including sulfates and non-sulfate types. It remains stable in formulations containing salts or alcohols. The recommended usage level is 0.1% to 2.0% by weight, depending on the application. Higher concentrations may improve performance but could risk over-conditioning.
Safety profiles confirm Polyquaternium-7 is mild and non-irritating for most users. It is free from harmful byproducts like acrylamide monomers due to advanced purification processes. Regulatory approvals include compliance with COSMOS, ECOCERT, and FDA guidelines.
Storage requires keeping the product in a cool, dry place away from direct sunlight. Optimal temperatures range between 10°C and 30°C. Prolonged exposure to heat or freezing conditions may alter viscosity or stability. Containers should remain tightly sealed to prevent contamination or moisture absorption.

Applications of Whole Polyquaternium-7 / Poly (DMDAAC/AM)
Whole Polyquaternium-7, also known as Poly (DMDAAC/AM), is a versatile polymer widely used in personal care and industrial products. Its unique properties make it valuable for multiple applications. The compound works as a conditioning agent in hair care products. It helps reduce static, improves hair manageability, and adds shine. Shampoos and conditioners often include it to enhance texture and prevent tangles. The polymer forms a thin film on hair strands, protecting them from damage caused by heat or environmental factors.
In skincare, Polyquaternium-7 acts as a moisturizing agent. Lotions, creams, and serums use it to keep skin hydrated. It binds water to the skin’s surface, preventing dryness. The ingredient is gentle, making it suitable for sensitive skin. Its film-forming ability also creates a barrier against pollutants and irritants.
Household cleaning products benefit from Polyquaternium-7. It prevents dirt from redepositing onto fabrics during washing. Laundry detergents and fabric softeners use it to maintain color brightness and fabric softness. The polymer’s antistatic properties reduce lint buildup on clothes.
Industrial applications include water treatment processes. Polyquaternium-7 helps clarify water by binding to suspended particles. This makes filtration more efficient. The compound is also used in paper manufacturing to improve sheet strength and reduce dust. Its adhesive properties make it useful in coatings and paints, enhancing durability and finish.
The cosmetic industry relies on Polyquaternium-7 for product stability. It prevents ingredients from separating in formulations. This ensures consistent texture and performance in products like gels and mousses. The polymer’s compatibility with other ingredients allows for flexible formulation design.
Polyquaternium-7 is valued for its safety and biodegradability. It breaks down more easily than some synthetic polymers, reducing environmental impact. Regulatory bodies approve its use in consumer products at specified concentrations. Its multifunctional nature supports innovation across industries while meeting performance and safety standards.
