Distarch Phosphate

What is Distarch Phosphate?

Distarch phosphate is a chemically modified starch obtained from natural plant sources such as corn, wheat, or potato starch. It features phosphate cross-links that enhance its stability and functionality, creating a resilient structure resistant to breakdown. Primarily used in powder-based cosmetics like foundations, blushes, and dry shampoos, as well as some emulsions, it works by selectively absorbing oils and water to mattify skin and control shine. Its cross-linked network allows controlled swelling, improving product spreadability and adhesion without stickiness. This modification boosts flow properties, reduces lump formation, and strengthens cohesion in pressed formats, ensuring consistent performance and user-friendly application across various formulations.

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.

Binder

Helps hold solid ingredients together to form cohesive tablets, compacts, or sticks, improving pressability, integrity, and wear of the finished product.

Absorbent

Absorbs water and/or sebum to reduce greasiness and shine, improve dry touch, and help keep powders and emulsions feeling lighter on skin.

Binding

Provides cohesion by helping ingredients stick together, improving the strength and integrity of pressed powders, tablets, or solid bars.

Benefits

Helps control shine by absorbing excess sebum for a drier, matte finish.

Maintains powder smoothness and flow, preventing clumping during storage and use.

Strengthens product integrity by binding ingredients together for better durability.
