Dextrin Myristate

What is Dextrin Myristate?

Dextrin Myristate is a modified carbohydrate ingredient formed by esterifying dextrin—a short-chain polysaccharide derived from hydrolyzing natural starches like corn or potato—with myristic acid, a saturated fatty acid sourced from plant oils such as palm kernel. Commonly found in powder-based cosmetics, cleansers, and emulsion products like foundations, dry shampoos, and lotions, it performs multiple roles. As an anticaking agent, it absorbs excess moisture to prevent particle clumping, maintaining free-flowing textures. In surfactant capacity, it reduces surface tension, aiding in dirt removal and foam generation during cleansing. As an emulsifying agent, it creates a protective film at oil-water interfaces, stabilizing formulations against separation for even application and consistent feel.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Anticaking agent
Prevents powders from clumping by reducing moisture pickup and improving flow, keeping loose and pressed powders uniform during storage and use.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Helps powders flow smoothly by absorbing moisture and preventing lumps.

Supports cleansing action by lowering surface tension for better dirt removal.

Stabilizes emulsions in lotions and creams for uniform texture.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Users of powder cosmetics seeking clump-free application.
Those with rare allergies to starch derivatives.
Individuals with dry or sensitive skin preferring stable, non-separating products.
Individuals sensitive to fatty acid esters.
People looking for gentle surfactants in cleansers and shampoos.
People preferring fully anhydrous product formulations.

Safety Notes

  • Rated low hazard by environmental working group assessments.
  • Non-comedogenic, unlikely to clog pores.
