Product: Polyquaternium-39 (PQ-39)
Rchem Polyquaternium-39 is a high-performance, ternary copolymer supplied as a clear, viscous liquid, specifically designed for the ultimate 2-in-1 and 3-in-1 conditioning system. This advanced polymer is a cornerstone of modern shampoo technology, uniquely capable of forming a stable, coacervate complex with anionic surfactants and silicones. This action allows conditioning agents to deposit efficiently onto the hair during the shampooing process, delivering detangling, softness, and shine in a single step without compromising lather or cleansing.

Frequently Asked Questions:
What is the primary mechanism that makes PQ-39 work in 2-in-1 shampoos?
Its primary mechanism is coacervation. When the shampoo is diluted with water during use, the cationic PQ-39 forms a complex with the anionic surfactants. This complex, which also entraps silicone droplets, becomes insoluble and deposits directly onto the hair shaft. This delivers the conditioning agents precisely where they are needed, while the lather rinses cleanly away.
While PQ-7 and PQ-10 are excellent conditioning agents, PQ-39 is specifically engineered as a deposition polymer. PQ-7 and PQ-10 provide conditioning but are not as effective at depositing and stabilizing high levels of silicones in an anionic system. PQ-39 is the key to creating a true, stable 2-in-1 shampoo that doesn't separate.
How does Polyquaternium-39 differ from other conditioning polymers like PQ-7 or PQ-10?
Yes, absolutely. PQ-39 itself is a clear liquid and is perfectly suited for clear shampoo formulations. The "pearlescent" coacervate phase only forms upon dilution with water during use, so the product in the bottle can remain perfectly clear.
Can PQ-39 be used in a clear shampoo?
Because it is designed to deposit its complex onto the hair, there is a potential for cumulative buildup over time, especially if combined with heavy silicones. This is a trade-off for the high level of conditioning it provides. Formulators often balance this by recommending occasional use of a clarifying shampoo.
Is there a risk of buildup with PQ-39?
It is typically added to the water phase of the formulation. The final product pH is critical and should usually be in the range of 5.5 to 7.0 for optimal coacervation and performance. It is compatible with a wide range of anionics like SLES but should be evaluated for compatibility with other cationic ingredients. Always refer to the Safety Data Sheet (SDS) for comprehensive handling information.
