Products Description
Polyquaternium-51 is an advanced biocompatible copolymer composed of 2-methacryloyloxyethyl phosphorylcholine (MPC) and butyl methacrylate. Known for mimicking the structure of human cell membranes, this premium cosmetic raw material delivers exceptional moisture retention and cellular protection. Its unique zwitterionic structure allows it to form a breathable, highly stable hydration barrier on the skin and hair surface, significantly outperforming traditional humectants like hyaluronic acid in sustained moisture delivery. Primarily utilized in high-end skincare, hair care, and daily chemical formulations, it is favored for its ability to restore barrier function and impart a smooth, non-sticky tactile feel.
As an established manufacturer and raw material supplier, Xi'an Hao Ze Bio Technology Co., Ltd. offers comprehensive B2B partnership solutions, including bulk Polyquaternium-51 supply, custom synthesis, and private label OEM/ODM services. We support cosmetic brands, formulators, and global distributors with rigorous quality control, stable mass production, and flexible packaging options to meet diverse commercial specifications.

Detailed Information
What makes Polyquaternium-51 superior for moisture retention?
Polyquaternium-51 features a phospholipid polar group that mirrors the natural cell membrane structure of human skin. This allows the molecule to integrate seamlessly with the stratum corneum, creating a resilient biomimetic membrane. Unlike conventional humectants that simply draw moisture from the air, this ingredient actively locks in hydration and prevents transepidermal water loss (TEWL) even under low-humidity conditions.
Formulators choose this compound because it provides long-lasting hydration without leaving a heavy or greasy residue. Its dual hydrophilic and hydrophobic properties enable it to remain bound to the skin or hair cuticle through multiple rinse cycles, ensuring sustained performance in daily-use cosmetic formulations.
How does Polyquaternium-51 enhance hair care products?
In hair care applications, Polyquaternium-51 acts as an exceptional conditioning agent that repairs damaged cuticles and improves overall manageability. It adsorbs effectively onto the hair shaft, forming a protective shield that guards against thermal styling damage, UV exposure, and environmental pollution.
Brands incorporate this ingredient into shampoos, conditioners, and leave-in treatments to reduce frizz, enhance combability, and restore natural shine. Because it does not cause heavy buildup, it is particularly effective for fine or damaged hair types requiring lightweight structural repair.
