DIMETHICONE PEG-8 OLIVATE.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING

DIMETHICONE PEG-8 OLIVATE is a precision silicone derivative, uniquely infused with olive oil fatty acids, designed to optimize skin hydration and tactile sensation. It acts as a sophisticated emollient and skin conditioner, simultaneously functioning as a vital emulsifier in complex formulations.

Science

Mechanism of Action

This ingredient operates by forming a breathable, protective film on the skin's epidermal layer. This polymeric barrier effectively minimizes transepidermal water loss, thereby preventing dehydration and promoting sustained moisture retention. The result is a perceptibly smoother and silkier skin texture, which can subtly diminish the appearance of fine lines. The 'olivate' component, derived from olive oil fatty acids, is believed to augment its superior conditioning and emollient properties. Furthermore, its emulsifying capability ensures the stable integration of immiscible oil and water phases in cosmetic products.

Stability

Optimal stability is observed within a functional pH range of 5.5 to 8.5. Hydrolysis rates are dependent on both pH and active concentration; for example, at pH 5 and 1% active, approximately 20% hydrolysis occurs within 45 days, while at pH 8 and 5% active, the same degree of hydrolysis takes roughly 165 days. It must be incorporated into the water phase of formulations and should not be heated above 50°C (122°F/125°F). When formulating emulsions, DIMETHICONE PEG-8 OLIVATE should be blended in once the temperature has dropped below 50°C.

Although a direct Cosmetic Ingredient Review (CIR) assessment specifically for DIMETHICONE PEG-8 OLIVATE was not identified, its close chemical relative, PEG-8 Dimethicone, was reviewed by the CIR Expert Panel in 2014 and deemed safe for cosmetic applications at concentrations up to 5.6%. Furthermore, dimethicone, methicone, and other substituted-methicone polymers have collectively been assessed as safe for cosmetic use when formulated to be non-irritating, supporting a low risk profile for this ingredient.
