Myrica Cerifera Fruit Wax is a versatile, plant-derived lipid that acts as an emollient and film-former, enhancing formulation stability and sensory experience. It contributes a soft, buttery feel to products while providing a protective barrier on the skin.

Summary

Emollient Film-forming Viscosity controlling Skin conditioning agent Co-emulsifier

Science

Mechanism of Action

This ingredient forms a flexible, protective layer on the skin, mimicking its natural function on the bayberry fruit to prevent moisture loss and environmental stress. This film helps to retain moisture in the deeper epidermal layers, promoting a smoother and more elastic skin appearance. In cosmetic formulations, it significantly increases viscosity and consistency, functioning as a co-emulsifier to stabilize oil-in-water emulsions and reduce tackiness. Chemically, it is classified as a 'vegetable tallow' or hard butter, predominantly composed of saturated long-chain fatty acid glycerides, which imparts its characteristic light and soft skin feel.

Stability

Possesses a low melting point of 40-55°C combined with high hardness, facilitating excellent spreadability. Its chemical structure, rich in saturated fatty acids, confers high oxidative stability, minimizing the risk of rancidity. It is broadly compatible with virtually all cosmetic fats and oils.

Synergies

  • Compatible with virtually all cosmetic fats and oils for enhanced stability and texture.

Conflicts

  • Can lead to crystallization, known as a 'blooming effect', when combined with clays, effect pigments, or dyes, particularly on lipstick or hot melt surfaces. This effect makes it generally not recommended for color cosmetic preparations where visual uniformity is paramount.
