Science
Mechanism of Action
On the skin, PEG-30 Castor Oil primarily acts to emulsify and solubilize, ensuring the homogeneous distribution of both oil- and water-soluble components, including fragrances and pigments. In cleansing applications, its surfactant properties efficiently dissolve impurities and remove excess sebum. Furthermore, like other polyethylene glycols, it contributes to skin hydration by attracting and retaining water molecules, thereby minimizing transepidermal water loss.

Stability
As a hydrophilic and ethoxylated derivative, PEG-30 Castor Oil exhibits excellent water solubility, functioning effectively as an oil-in-water emulsifier and solubilizer for a broad range of ingredients, including oils and fragrances. It notably enhances formulation texture, leading to smooth and stable product consistency, and is generally resilient against microbiological degradation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG-30 Castor Oil, along with related PEGs, safe for cosmetic use at concentrations up to 50%, provided formulations are non-irritating. While generally well-tolerated topically, there's a noted potential for it to increase the sensitization risk of other ingredients within a formulation. Concerns regarding toxic impurities such as ethylene oxide and 1,4-dioxane exist, underscoring the necessity for stringent purification during manufacturing.
