Polyquaternium-7 (PQ7) is a synthetic polymer used in cosmetics and toiletries for its conditioning, detangling, moisturizing, and lather-enhancing properties. It is a multifunctional component that provides benefits to both hair and skin. However, it can cause persistent stains on textiles, especially when used in shampoos and shower gels. It is restricted in cosmetics and has use, concentration, or manufacturing restrictions.
Conditioning: PQ7 reduces frizz and improves manageability of hair. Detangling: It aids in detangling hair by reducing inter-fiber friction. Moisturizing: Some polyquats act as humectants, attracting and binding moisture to the skin, improving hydration and reducing dryness. Skin Conditioning: PQ7 creates a protective barrier on the skin's surface, minimizing water loss and protecting against environmental irritants, resulting in smoother and softer skin.

Generally considered safe for topical application. However, allergic reactions may occur in some individuals, especially those with hypersensitive skin or skin conditions. The suggested concentration of Polyquaternium 7 in skincare and haircare formulation is 0.5-5%., above which it is considered to cause an allergic reaction on your body.
For external use only. Avoid contact with eyes. If irritation occurs, discontinue use and consult a healthcare professional.
Polyquaternium-7 is a synthetic copolymer derived from diallyl dimethyl ammonium chloride and acrylamide.

Environmental Concerns: While polyquats are safe for human use, concerns have been raised about their impact on the environment. Some polyquats are not easily biodegradable and may accumulate in aquatic environments, potentially posing a risk to aquatic organisms. However, more research is needed in this area. Recommended usage level: 1 - 4% Appearance: Clear, colorless viscous liquid Preserved with: Sodium Benzoate Solubility: Soluble in water Storage & Shelf-Life: 2 years from the date of manufacture if stored in a clean, dry place at 20 - 40°C, away from direct heat and sunlight. Textile Stains: Polyquaternium-7 can cause persistent stains on textiles, especially when used in shampoos and shower gels. This is due to the strong bond between the polyquaternium-film and the dirt, making it nearly impossible to remove the stains. Other Concerns: Use restrictions (high): Restricted in cosmetics and has use, concentration, or manufacturing restrictions. Non-reproductive organ system toxicity (moderate): Classified as expected to be toxic or harmful. Ecotoxicology (low): Suspected to be an environmental toxin and be persistent or bioaccumulative. Contamination concerns (high): Chemical - Acrylamide.
