Science
Mechanism of Action
This ingredient functions primarily as a surfactant, effectively bridging oil and water phases to create stable emulsions and improve product consistency. Its solubilizing properties ensure uniform dispersion of fragrances and pigments, preventing separation. Additionally, it offers skin conditioning benefits for a smoother feel and aids in cleansing by attracting and lifting impurities from the skin's surface.

Key findings
- 01 Related PEG-30 Castor Oil was found safe for topical application, demonstrating non-irritating and non-sensitizing properties at these low concentrations.
- 02 PEG-30 and -40 Hydrogenated Castor Oil, related components, were deemed safe for cosmetic use by the CIR Expert Panel, with no observed dermal or ocular irritation.
Transparency
Dusting Analysis
As a functional ingredient primarily serving as an emulsifier, solubilizer, and surfactant, its concentration is determined by specific formulation requirements rather than a minimum 'active' threshold for direct skin benefits. Therefore, it is not typically 'dusted' in the context of active ingredients.
The Formula
Formulation
Stability
The ingredient exhibits stability within a pH range of 6.0 to 7.5, aligning with the typical pH of a 5% aqueous solution of PEG-30 Castor Oil. It is susceptible to hydrolysis and degradation when exposed to strong acid or strong alkali conditions.

Safety
Safety Profile
The CIR Expert Panel has concluded that PEG-30 HYDROGENATED CASTOR OIL PCA ISOSTEARATE, among 130 related PEGylated oils, is safe as used in cosmetic formulations when properly purified and formulated to be non-irritating. While low concentrations (1-5%) of PEG-30 Castor Oil are considered non-irritating, some irritation has been observed at higher concentrations (e.g., 50%) with other related PEG Castor Oils. Potential contamination risks, such as ethylene oxide and 1,4-dioxane, are a concern if not adequately purified. This ingredient, derived from Castor Oil and PEG Castor Oil, holds approval by the FDA as both direct and indirect food additives.
