PPG-24-Glycereth-24

What is PPG-24-Glycereth-24?

PPG-24-Glycereth-24 is a polyether compound synthesized by reacting glycerin with propylene oxide and ethylene oxide, yielding a structure with 24 propylene glycol units and 24 glycerin ethoxylate chains. This amphiphilic molecule excels in water-based cosmetic systems, commonly found in cleansers, shampoos, lotions, and hair conditioners. It works by solubilizing oils and fragrances into water phases, lowering interfacial tension to promote stable emulsions, and enabling efficient surfactant action for cleansing and foaming. Its hydrophilic nature supports viscosity control and enhances product spreadability, delivering a lightweight feel without greasiness. In formulations, it bridges hydrophobic and aqueous components, ensuring uniform distribution and prolonged stability across diverse pH environments.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Improves solubility of active ingredients in water-based formulas.

Stabilizes emulsions for smoother, consistent product textures.

Boosts cleansing and foaming for effective yet gentle washing.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Users of lightweight lotions and serums for even application.
Those with rare allergies to polyether compounds.
People with acne-prone skin, as it is non-comedogenic.
People preferring formulations without synthetic polymers.
Individuals seeking stable, hydrating rinse-off cleansers.
Individuals sensitive to glycol derivatives, per patch test advice.

Safety Notes

  • Considered low hazard overall by safety assessments.
  • Non-comedogenic, minimizing pore-clogging potential.
