Science
Mechanism of Action
This ingredient operates by establishing a non-occlusive, emollient layer on the skin's surface, effectively diminishing trans-epidermal water loss and promoting a soft, smooth tactile sensation. Concurrently, its refatting properties aid in the replenishment and maintenance of the skin's natural lipid barrier.

Formulation
Stability
As an ester derived from soybean oil, Soybean Palmitate is inherently oil-soluble. While specific optimal pH or stability data for this isolated ester are not available, general guidance for soybean oil suggests enhanced stability when protected from atmospheric oxygen, with minimal degradation observed around pH 6-7. Storage in airtight, light-resistant containers at temperatures not exceeding 25°C is recommended to preserve integrity.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific safety assessment for Soybean Palmitate (CAS 227200-28-4). While the CIR has reviewed other soy-derived ingredients, some of these assessments have concluded with insufficient data for certain components. No SCCS (Scientific Committee on Consumer Safety) opinion is available for this ingredient, indicating a lack of comprehensive, dedicated safety data.

Verdict
Despite its proposed emollient and refatting properties beneficial for dry and normal skin types, the current absence of specific clinical studies and comprehensive safety reviews (CIR 'not reviewed') for Soybean Palmitate necessitates further data for a conclusive assessment.
