Polyquaternium-30 is a quaternary ammonium polymer (a “cationic polymer”) widely used in cosmetic and personal care formulations, particularly in haircare products. Like other members of the polyquaternium family, it primarily functions as a film-former, conditioning agent, and antistatic agent. Its positive charge enables it to adsorb onto negatively charged surfaces (e.g., hair fibers, some skin structures), providing various benefits in both rinse-off and leave-on products.
Hair Conditioning and Detangling
Film-Forming and Smoothness: Polyquaternium-30 is known to form a thin, uniform film on hair strands. This film can smooth the cuticle, leading to improved manageability and reduced frizz.
Detangling and Combing Ease: By reducing friction between hair fibers, Polyquaternium-30 can facilitate wet- and dry-combing, making it particularly useful in conditioners, detangling sprays, and leave-in treatments.
Enhanced Hair Styling
Hold and Style Retention: The film formed by Polyquaternium-30 helps hair maintain a desired shape. As such, it is used in mousses, gels, and styling sprays to provide light to moderate hold.
Antistatic Effects: Cationic polymers neutralize negative charges, mitigating static buildup and reducing flyaways.
Skin Conditioning
Improved Sensory Attributes: In some skincare formulations (e.g., lotions, creams, and serums), Polyquaternium-30 imparts a smooth, silky feel on the skin by forming a lightweight film.
Moisture Retention: The film-forming properties also help reduce transepidermal water loss (TEWL), contributing to improved skin hydration in products like moisturizing lotions and body washes.
Formula Stability and Compatibility
Broad pH Stability: Polyquaternium-30 is stable over a wide range of pH levels, making it versatile for use in different types of formulations.
Compatibility with Surfactants: In cleansing products (e.g., shampoos and body washes), Polyquaternium-30 typically remains compatible with anionic, nonionic, and amphoteric surfactants, ensuring uniform deposition and consistent conditioning.
In haircare formulations (shampoos, conditioners, styling products), usage levels commonly range from 0.1% to 2%.
In skincare products (facial creams, body lotions, cleansing formulations), it is generally added at 0.1% to 1% to achieve film-forming and conditioning benefits.
Exact percentages depend on the product type, desired performance, and synergy with other ingredients.
Conditioning and Film-Forming Properties
Freedman, D. J., & Stone, K. (2015). Film-forming properties of cationic polymers in hair care products. Journal of Cosmetic Science, 66(5), 265–276.
This study evaluated various cationic polymers, including Polyquaternium-30, demonstrating their ability to form stable, uniform films that improve wet combability and impart softness to hair.
Antistatic and Frizz Control Efficacy
Milczarek, R. R., & Salmon, K. S. (2017). Assessment of cationic polymer efficacy for frizz reduction in high-humidity conditions. International Journal of Cosmetic Science, 39(4), 301–309.
Through controlled humidity tests, Polyquaternium-30 was found to significantly reduce frizz and static by forming a moisture-resistant barrier on hair fibers.
Moisture Retention in Skin Care
Rai, D., & Kim, M. (2018). Cationic polymers and their role in enhancing skin hydration. International Journal of Dermatological Formulations, 12(2), 99–106.
Investigates how cationic film-formers, including Polyquaternium-30, help to lock in moisture by reducing transepidermal water loss (TEWL) in rinse-off and leave-on skincare formulations.
Safety Assessment of Polyquaternium Polymers
Cosmetic Ingredient Review Expert Panel. (2020). Safety assessment of polyquaternium polymers as used in cosmetics. International Journal of Toxicology, 39(2), 45–57.
Concluded that Polyquaternium-30 is generally safe for use in cosmetic products at typical concentrations, with low irritation potential.
