PEG/PPG-10/65 COPOLYMER.

Valuable CAS - / CLEANSING, SOLVENT, SURFACTANT - CLEANSING

PEG/PPG-10/65 Copolymer is a synthetic polymer designed to integrate oil and water phases, acting as an effective emulsifier. It also functions as a skin conditioning agent, contributing to enhanced skin feel and sensory characteristics in topical formulations.

Science

Mechanism of Action

This non-ionic copolymer functions by lowering the interfacial tension between immiscible liquid phases, thereby enabling the formation and stabilization of emulsions. Its amphiphilic structure, with both polyethylene glycol (PEG) and polypropylene glycol (PPG) segments, allows it to interact with both hydrophilic and lipophilic components, preventing phase separation. Additionally, it can form a subtle film on the skin's surface, contributing to conditioning and a smoother feel.

Dusting Analysis

Not commonly dusted

PEG/PPG-10/65 Copolymer serves as a foundational formulating ingredient rather than an active compound, thus it is not subject to 'dusting' concerns, which typically apply to active ingredient concentrations.

Stability

Generally stable across a broad pH range; however, extreme acidic (below pH 3.0) or alkaline (above pH 9.0) conditions may compromise long-term stability and performance. It maintains integrity under typical formulation and storage conditions.

Synergies

  • Other non-ionic emulsifiers for enhanced emulsion stability.
  • Various emollients to optimize skin feel and spreadability.

Conflicts

  • Strong oxidizing agents which may degrade the polymer structure.
  • High concentrations of certain ionic surfactants, which may reduce its emulsifying efficacy.
