Cationic Conditioning Agent That Keeps Hair Smooth and Static-Free
Polyquaternium 7 is a water-soluble cationic polymer widely used across the hair care industry in shampoos, conditioners, detangling sprays and styling products. What makes it especially popular among cosmetic chemists worldwide is its rare ability to stay stable and active in anionic surfactant systems, where many other conditioning polymers lose their performance. This material belongs to the category of Silicones and Conditioning Surfactants for Hair, which brings together ingredients responsible for smoothness, manageability and finish in hair formulations.
The main function of this polymer is to form a thin film on the hair surface that reduces static charge, eases combing and leaves hair feeling soft without any weighing down effect. It is commonly applied in products for colored and damaged hair, in children's shampoos, in leave-in detangling sprays, and in volumizing formulas since it does not clump strands together or leave a greasy feel. In industrial shampoo manufacturing it is added to the water phase during mixing at a temperature of about 40-50 degrees Celsius, with typical usage levels ranging from 0.5 to 3 percent depending on the desired conditioning strength. In conditioners and hair masks the concentration is often raised to 2-4 percent, combined with cationic surfactants and fatty alcohols for a stronger effect.
Polyquaternium 7 pairs well with silicones, oils and plant extracts, allowing flexible formulation across many product types. For added shine and slip, formulators frequently combine it with Natural Coconut Silicone 10 ml, while for a stronger nourishing and repairing effect it works well alongside Aminosilicone 100 g, which further softens the hair structure. For larger production runs, many manufacturers rely on Natural Coconut Silicone 1 L to maintain consistency across bigger batches.
The 50 ml packaging is intended mainly for home cosmetic making and small trial batches, allowing formulators to test a shampoo or conditioner recipe before scaling it up. This volume is enough for several experimental runs, texture evaluation and precise dosage adjustment for a specific formula. The polymer remains stable across a broad pH range, works well at room temperature during addition, and does not require any special activation conditions. Store the product tightly sealed, in a dry place away from direct sunlight and heat sources, avoiding sharp temperature fluctuations.
Beyond hair care, this polymer is also used in body lotions, hand creams with a light slip feel, and in certain household chemical formulas where an antistatic effect on textile fibers is needed. This versatility makes polyquaternium 7 a foundational ingredient for laboratories working across both hair care and textile conditioning applications.
Leave-In Detangling Mist
Distilled water 91 ml
Polyquaternium 7 2 ml
Glycerin 2 ml
Panthenol 1 ml
Jojoba oil 1 ml
Fragrance 0.5 ml
Preservative 1.5 ml
Combine water with glycerin, panthenol and jojoba oil, stirring until fully blended. Slowly add polyquaternium 7 without vigorous shaking to avoid foaming, then mix gently until uniform. Add fragrance and preservative at the end, transfer the mixture into a spray bottle and apply to damp hair before combing.
