Science
Mechanism of Action
Operating primarily as a skin conditioning agent, Isopropyl Ricinoleate establishes a non-occlusive protective barrier on the skin's surface. This barrier effectively minimizes transepidermal water loss (TEWL), thereby significantly improving skin hydration and strengthening the natural skin barrier function. It also contributes to a desirable skin feel, promoting a glossy and smooth finish.

Key findings
- 01 Clinical observations confirm that Isopropyl Ricinoleate, within a 3-20% concentration range, delivers notable moisturizing benefits. Sensory evaluations specifically highlight its ability to enhance skin gloss and shine while exhibiting minimal tackiness and residue post-application. Its influence on transepidermal water loss (TEWL) has been substantiated through testing.

The Formula
Formulation
Stability
As an oil-soluble ester with very low water solubility (0.01125 mg/L at 25 °C), Isopropyl Ricinoleate is optimally incorporated into oil-based or emulsion formulations, where it functions effectively as a non-ionic oil derivative.
Safety
Safety Profile
The CIR Expert Panel has concluded that Isopropyl Ricinoleate is safe for use in cosmetics, provided it is formulated to be non-irritating. Studies on related castor oil derivatives and clinical experience generally indicate a low potential for irritation or sensitization reactions.

Verdict
Isopropyl Ricinoleate is a valuable emollient for enhancing skin hydration, barrier function, and aesthetic appeal, though its unknown comedogenic potential, particularly in light of other isopropyl esters, warrants careful consideration for acne-prone skin types.
