Product: Polyquaternium-7 (PQ-7)
Rchem Polyquaternium-7 is a high-purity, cationic polymer supplied as a clear, viscous liquid. This versatile and highly effective conditioning agent is renowned for its ability to deliver exceptional detangling, smoothness, and manageability to hair and skin. As a substantive film-former, it deposits a uniform, non-greasy layer that neutralizes static charge, reduces frizz, and provides a silky, soft feel. It is a cornerstone ingredient in rinse-off and leave-in formulations for its reliable performance and compatibility with anionic surfactants.

Frequently Asked Questions:
What is the primary function of Polyquaternium-7 in a shampoo?
Its primary function in shampoo is to provide instant conditioning and detangling while you wash. Unlike traditional conditioners that can be rinsed away by surfactants, PQ-7 is designed to be compatible with them, allowing it to deposit onto the hair and provide slip and softness even in a cleansing base, creating a 2-in-1 effect.
Both are cationic conditioners, but their origin and compatibility differ. PQ-10 is a cellulose derivative and is also anionic compatible, but it can sometimes build up more than PQ-7. PQ-7 is a synthetic polymer known for providing a very clean, non-build-up feel and is exceptionally stable in clear formulations.
How does Polyquaternium-7 differ from Polyquaternium-10?
It is known for being a low-buildup polymer compared to other quats like Polyquaternium-6 or -37. Its film-forming properties are designed to be substantive yet lightweight, rinsing cleanly over time. However, as with any cationic polymer, buildup can occur with extreme overuse, which is why it is often used in rinse-off products.
Can Polyquaternium-7 cause buildup on hair?
Absolutely. In body washes and shower gels, it deposits a light, silky film on the skin that helps to mitigate the drying effects of surfactants. It provides a smooth, moisturized after-feel without leaving a greasy or tacky residue.
Is PQ-7 suitable for use in skin care products like body wash?
Store in a cool place and avoid freezing. It is a ready-to-use liquid and can be added to the water phase at any stage of cooling. Due to its cationic nature, it may form complexes with strong anionic polymers, which can be used intentionally to create pearlescent effects or may need to be avoided for clarity. Always refer to the Safety Data Sheet (SDS) for comprehensive handling information.
