| Résumé : |
Sensitive skin is becoming a rising concern in our modern society. Many different extrinsic and intrinsic factors such as pollution, increased exposure to chemicals, stress of our hectic lives, hormones etc., affect the quality and the condition of the skin. Formulating with ingredients that enable milder products with simplicity, pleasant aesthetics and sensory, while maintaining the performance expected by consumers, has become a challenge. A new generation of multifunctional acrylate-based polymeric emulsifier contributes to overcome the limitation of existing technologies. Mildness of this generation of polymeric emulsifier has been compared to well-known skin irritant substances by surface tension measurement. Formulators are nowadays offered with a robust and highly efficient solution for emulsion stability and mildness without compromise on the pleasant sensory and the variety of galenics in the skin and sun care markets. |

- How is sensitive skin impacting the quality of life ?
- Barrier function is critical in sensitive skin
- New generation of hydrophobically modified polymer for emulsion stabilization
- Minimize surface activity and the skin's percutaneous absorption of emulsion stabilizers
- Water resistance with good sensory for the suncare market
- Speed up and ease the formulation process while making affordable formulations with good aesthetics
- FIGURES : 1. Skin barrier disruption by surfactant and permeation of non desirable substances - 2. Emulsion stabilization by polymeric emulsifier. Oil droplets are dispersed into a polymer associative microgel network - 3. Surface tension measurements using kruss tensiometer at 25°C, 30 min - 4. No re-emulsification mechanism enabling water-resistance of sunscreens stabilized with non surface-active polymeric emulsifier - 5. A quantity of 0.05% of Permulen TM EZ-4U polymeric emulsifier is sufficient to stabilize a liquid macro-emulsion of Sesame Seed Oil of 600-1, 100 mPa-s (Brookfield DV-1, 20 rpm, 25°C, 24 hours, spindle 2) |
