Product Uses

Quaternium-73, also known as Pionin, is an extremely effective active ingredient widely utilized in the treatment of acne and inflammatory skin conditions. It works by inhibiting the growth of Propionibacterium acnes and Malassezia furfur, the primary culprits behind breakouts and dandruff. Beyond its antimicrobial prowess, it helps regulate sebum production and reduce skin irritation. This ingredient is highly recommended for targeted acne spot treatments, clarifying serums, anti-dandruff shampoos, and balancing creams. Given its high efficacy at trace amounts (ppm levels), it offers formulators a cost-effective solution with massive market potential in the "clean beauty" and "dermaceutical" sectors.

Formula Suggestions

The recommended dosage for Quaternium-73 is typically between 0.001% and 0.005% for leave-on products and up to 0.01% for rinse-off products. It should be pre-dissolved in a solvent like Propylene Glycol or Ethanol before being added to the formula, preferably during the cool-down phase (below 45°C) to maintain stability. It is compatible with most non-ionic and cationic surfactants but may form precipitates with certain anionic polymers. Synergy Tip: Combine with Salicylic Acid for enhanced follicular penetration and a comprehensive approach to acne clearing.
