Polyquaternium 10 is a white granular powder with a characteristic amine odor. In cosmetics and personal care products, it is used mainly in the formulation of hair care products, lotions and makeup.
When used in hair care products, Polyquaternium 10 can reduce static electricity. It enhances the appearance and feel of hair, by increasing hair body, suppleness, or sheen, or by improving the texture of hair that has been damaged physically or by chemical treatment.
Polyquaternium 10 is a synthetic polymer compound primarily used in hair care products due to its value as a flexible film-forming and anti-static agent. Of note, it offers conditioning and detangling benefits.

Polyquaternium 10 also shows up in skin care formulas such as cleansers, exfoliants, and moisturizers where it is known to offer emollient properties and can be used to control the viscosity of a formula, thereby enhancing the texture.

As a raw material, it has a white granular powder appearance and is soluble in water.

Polyquaternium 10 has decades of history of safe use in cosmetics and was most recently reevaluated by the Cosmetic Ingredient Review Expert Panel in 2008, where it was once again deemed safe. Their report surveyed 396 products using polyquaternium-10, with concentrations ranging from 0.004% to 1.5%.
Polyquaternium 10 is a polymeric quaternary ammonium derivative of hydroxyethyl cellulose that is used in cosmetics as a conditioner, thickener, and emollient at concentrations of I 0.1 %-5%. Polyquaternium 10 has, at most, only a low potential to penetrate the stratum corneum but is adsorbed by keratinous surfaces. The oral LDso of Polyquaternium 10 was not obtained at 16g/kg in rats. Inhalation, dermal, and ocular animal test data indicated, at most, only a low degree of toxicity at test concentrations of Polyquaternium10 greater than that used in cosmetic products. Polyquaternium-10 with and without metabolic activation was not a mutagen in three separate assay systems. Polyquaternium 10 was neither an irritant nor a human sensitizer when tested at 2.0%. Cosmetic products containing .up to 1 o/o Polyquaternium 10 were not human irritants, sensitizers, or photosensitizers. On the basis of the information presented, it is concluded that Polyquaternium 10 is safe as a cosmetic ingredient in the present practices of use.
Polyquaternium 10 is a skincare ingredient that is used in moisturizers, hair care products, and make-up. It is mainly used in hair care products to reduce static and minimize flyaways.

Polyquaternium 10 comes as a white powder with a slight amine scent. It works by absorbing to protein-containing surfaces such as the hair, enhancing the appearance of shine, increasing volume, and improving the feel of damaged or chemically treated hair.
