PEG/PPG-22/23 DIMETHICONE.

Valuable / SURFACTANT - EMULSIFYING

PEG/PPG-22/23 Dimethicone is a water-soluble silicone polymer that functions as a versatile emulsifier, wetting agent, and film-former in advanced skincare. It creates a breathable barrier on the skin, enhancing hydration, preventing moisture loss, and improving the sensory profile of formulations across various product types.

Emulsifying Wetting Foam Stabilizing Moisturizing Film forming

Science

Mechanism of Action

This ingredient operates as a surfactant and emulsifying agent, effectively reducing interfacial tension to facilitate the creation of stable oil-in-water or water-in-oil emulsions. Upon dermal application, it forms a protective, vapor-permeable film that minimizes transepidermal water loss (TEWL) and helps to prevent the penetration of external environmental stressors into the stratum corneum. Its inherent viscoelastic and hydrophobic properties contribute to a lubricious skin feel, providing a noticeable shine and enhanced slipperiness.

Stability

As an alkoxy polysiloxane containing a PEG moiety, this ingredient is hydrophilic, exhibiting solubility in both water and various alcohols. Its water solubility is observed to increase with a higher count of alkoxy groups within its polymeric structure, leading to its designation as a 'water-soluble silicone'.
