PPG-2 C9-11 PARETH-8.

Valuable CAS - / CLEANSING, SURFACTANT - EMULSIFYING

PPG-2 C9-11 Pareth-8 is a non-ionic surfactant and emulsifying agent engineered to stabilize complex oil-in-water or water-in-oil formulations. Its molecular structure efficiently reduces interfacial tension, ensuring consistent product texture and supporting effective cleansing by solubilizing oily impurities.

Summary

Emulsifying Surfactant

Science

Mechanism of Action

This ingredient operates as a non-ionic surfactant and emulsifier, leveraging a molecular architecture derived from C9-11 synthetic alcohol with both polyethylene glycol and polypropylene glycol ether units. This structure is precisely designed to lower interfacial tension between immiscible phases, such as oil and water, enabling the formation and maintenance of stable emulsions. In topical applications, it facilitates the dispersion of impurities and aids in effective cleansing by solubilizing hydrophobic substances like sebum and environmental pollutants.

Stability

PPG-2 C9-11 Pareth-8 exhibits robust stability across a pH range of 5-7, rendering it suitable for both alkaline and acidic formulations. A 1% solution typically presents a neutral pH. Its solubility in water can be enhanced, and self-aggregation mitigated, through the incorporation of a hydrotrope or an appropriate solvent. This ingredient demonstrates notable resistance to alkalis (up to 90g NaOH/l), various oxidizing and reducing agents, and water hardness.

Synergies

  • As a non-ionic compound, it is highly compatible with both anionic and cationic surfactants, offering broad formulation flexibility.
