POLYGLYCERYL-3 RICINOLEATE.

Valuable CAS - / SURFACTANT - EMULSIFYING

Polyglyceryl-3 Ricinoleate is a highly effective non-ionic emulsifier, essential for creating and stabilizing both oil-in-water and water-in-oil emulsions to achieve optimal product texture. Beyond its functional role, it acts as a significant skin conditioning agent, enhancing hydration and promoting a softer, more supple complexion.

Emulsifying Skin Conditioning Viscosity Controlling Moisturizing Surfactant Stabilizer Thickener Anticaking Agent

Science

Mechanism of Action

This ingredient functions primarily as a non-ionic emulsifier, adept at stabilizing diverse emulsion systems, including oil-in-water (O/W) and water-in-oil (W/O), which is critical for a smooth and consistent product texture. It also operates as a surfactant, effectively reducing surface tension to facilitate ingredient dispersion and offer mild cleansing properties. On the skin, Polyglyceryl-3 Ricinoleate provides direct benefits as a moisturizer and conditioning agent by helping to retain moisture, minimize transepidermal water loss (TEWL), and soften the skin. Additionally, it serves as a stabilizer, thickener, and anticaking agent, meticulously adjusting product viscosity and surface tension to prevent ingredient separation and improve the absorption of other active ingredients.

Stability

Polyglyceryl-3 Ricinoleate exhibits excellent stability under recommended storage conditions, resisting oxidation, color shifts, and changes in odor throughout a product's lifespan. It is versatile, allowing incorporation into formulations across a broad temperature spectrum, from -18°C to 50°C. For superior emulsion stability, particularly in water-in-oil systems, co-formulation with an appropriate thickener is advised, and the addition of 1% Magnesium Sulfate may be necessary.

Synergies

  • Enhanced emulsion stability when combined with suitable thickeners.
  • Improved water-in-oil emulsion stability with 1% Magnesium Sulfate.
  • Increased absorption and effectiveness of other active ingredients in formulations.

Conflicts

  • Potentially unsuitable for individuals with Malassezia folliculitis due to its ricinoleic acid component.
