DIETHYL MALATE

Description

Diethyl Malate is a versatile ester derived from malic acid, a naturally occurring alpha-hydroxy acid found in fruits like apples. This colorless, low-viscosity liquid serves as a multifunctional ingredient in skincare formulations. Primarily used as an emollient and skin-conditioning agent, Diethyl Malate helps improve the texture and feel of products while providing moisturizing benefits to the skin.

The ingredient exhibits excellent spreadability and quick absorption, making it ideal for lightweight formulations such as serums, lotions, and gels. Diethyl Malate acts as a solvent for other active ingredients, enhancing their penetration into the skin. It also functions as a pH adjuster, helping to maintain the optimal acidity of skincare products.

Research suggests that Diethyl Malate may have mild exfoliating properties, potentially aiding in the removal of dead skin cells and promoting a smoother complexion. Additionally, it can act as a humectant, attracting and retaining moisture in the skin. Its low comedogenicity makes it suitable for various skin types, including acne-prone and sensitive skin. Formulators often incorporate Diethyl Malate to improve product stability and extend shelf life.
