Polyquaternium-7, often referred to as PQ-7, is a synthetic polymer used in the cosmetic and personal care industry. It is a cationic quaternary ammonium compound with a high molecular weight. PQ-7 is well-known for its exceptional conditioning properties, making it a popular ingredient in hair care and skin care products. In this article, we will explore the properties, applications, and benefits of Polyquaternium-7.
Properties: Polyquaternium-7 is a water-soluble polymer that forms a clear, viscous liquid or gel when dissolved in water. It is cationic in nature, meaning it carries a positive charge. This positive charge allows PQ-7 to bind to the negatively charged surfaces of hair and skin, making it an effective conditioning agent. PQ-7 is compatible with a wide range of cosmetic ingredients, making it easy to incorporate into various formulations.
Applications:
- Hair Care Products: PQ-7 is widely used in hair care products, including shampoos, conditioners, hair masks, and styling products. Its conditioning properties help to improve the texture and manageability of hair. PQ-7 also reduces static, frizz, and flyaways, leaving the hair looking smooth and shiny.
- Skin Care Products: In skin care products, Polyquaternium-7 functions as a moisturizing and film-forming agent. It forms a thin film on the skin, which helps to retain moisture, leaving the skin feeling soft and hydrated. PQ-7 is often found in lotions, creams, body washes, and moisturizers.
- Personal Cleansing Products: PQ-7 is used in personal cleansing products like shower gels and liquid soaps to provide a luxurious and silky feel to the skin. Its conditioning properties make the cleansing experience more pleasant and less drying to the skin.
Benefits:
- Improved Hair Manageability: PQ-7 enhances the combability and manageability of hair by reducing tangles and knots. This results in easier styling and reduced hair breakage during combing or brushing.
- Enhanced Hydration: In skin care products, PQ-7 helps to lock in moisture, preventing water loss from the skin. This enhances skin hydration and helps to maintain a smooth and supple complexion.
- Static Reduction: PQ-7’s anti-static properties make it beneficial for controlling static electricity in both hair and skin, reducing frizz and flyaways.
- Non-Toxic and Safe: Polyquaternium-7 is considered safe for use in cosmetic and personal care products. It is non-toxic and non-irritating when used at recommended concentrations.
Conclusion: Polyquaternium-7 (PQ-7) is a versatile and effective conditioning agent commonly used in hair care and skin care products. Its cationic nature allows it to bond to hair and skin surfaces, providing enhanced manageability, moisturization, and static reduction. With its safe and non-toxic profile, PQ-7 continues to be a favored choice for formulators looking to improve the performance and sensory attributes of cosmetic and personal care formulations.
