Science
Mechanism of Action
On the skin, Myristyl Myristate acts as an emollient by forming a non-occlusive, protective film that effectively minimizes transepidermal water loss (TEWL), thereby enhancing skin hydration, softness, and smoothness. In formulations, it significantly improves texture, stability, and spreadability, preventing oil and water separation and imparting a desirable velvety, non-greasy finish.

Dusting Analysis
As an emollient designed to integrate into the oil phase and enhance product feel, Myristyl Myristate is not associated with 'dusting' or a powdery, chalky residue. Instead, it contributes to a smooth, velvety skin feel.
The Formula
Formulation
Stability
Myristyl Myristate maintains stability across a wide pH range (4-9) and is resilient to heat. It is compatible with anionic, nonionic, and cationic surfactants, improving product texture, spreadability, and emulsion stability. For optimal integration, it should be added to the oil phase of formulations.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined Myristyl Myristate to be safe for cosmetic use at reported concentrations up to 10%. It exhibits low to no reported toxicity, and is considered non-irritating and non-sensitizing to the skin. The FDA permits myristic acid, from which Myristyl Myristate is derived, for direct addition to food.

Verdict
Myristyl Myristate is a safe and effective emollient and texture enhancer, offering significant benefits for dry, sensitive, and normal skin types; however, its high comedogenicity warrants careful consideration for facial applications, especially for blemish-prone skin.
