Main Application Areas

1. Cosmetics (Primary Application)

Powder Compacts / Loose Powder / Face Powder

Usage: 2%~5% (for pressed powder), 5%~10% (for loose powder).

Function: Binder, anti-caking agent, provides slip, and improves makeup longevity.

Eyeshadow / Blush / Highlighter

Function: Enhances color payoff and adhesion, provides water resistance, and ensures a smooth, easy-to-blend texture.

Foundation / Concealer (Creams / Sticks)

Function: Improves spreadability, provides a matte oil-control finish, and ensures waterproof, long-lasting wear.

Mascara / Eyeliner

Function: Waterproofing, anti-smudging, and increases the smoothness of the paste.

Solid Perfume / Antiperspirant Sticks

Function: Solidifying agent (structuring) and provides a lubricious skin feel.

2. Pharmaceutical Industry

• Used as a lubricant and glidant for tablets and capsules. It functions similarly to Magnesium Stearate but offers superior slip.

• Improves the glossy appearance of pills and reduces sticking to punches (sticking).
