Science
Mechanism of Action
As a cationic polymer, POLYQUATERNIUM-30 carries a positive charge, enabling it to electrostatically adsorb onto the negatively charged surface of the skin. This interaction forms a thin, uniform film that perceptibly improves skin's sensory characteristics, imparting a smooth and silky feel. Mechanistically, this film reduces transepidermal water loss (TEWL), thereby supporting enhanced skin hydration and functioning primarily as an effective film-former and conditioning agent.

The Formula
Formulation
Stability
POLYQUATERNIUM-30 demonstrates robust stability across a wide pH range of 3-7 and exhibits heat tolerance; however, temperatures exceeding 80°C should be avoided to preserve its integrity.
Synergies
- Generally compatible with anionic, nonionic, and amphoteric surfactants, offering broad formulation versatility.
Conflicts
- Formulation compatibility requires careful consideration to avoid potential complexing, particularly with certain anionic ingredients.
- Extended use may lead to a subtle 'build-up effect' on the skin, which is generally reversible with proper cleansing protocols.
