What is Solanum Tuberosum (Potato) Starch?

Solanum Tuberosum (Potato) Starch comes from the starchy tubers of the potato plant, a staple crop belonging to the Solanaceae family. It is a fine, white powder composed mainly of two polysaccharides: amylose (linear glucose chains) and amylopectin (branched glucose chains), which enable its water-binding and gelling abilities. In skincare products such as powders, creams, masks, and lotions, it acts as a versatile aid by soaking up excess sebum and moisture to mattify the skin, binding particles for product cohesion, adding volume to enhance texture and spreadability, and adjusting thickness for optimal stability and application. This plant-derived ingredient delivers a lightweight, velvety finish, supporting formulations that feel comfortable and non-greasy on the skin.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Absorbent
Absorbs water and/or sebum to reduce greasiness and shine, improve dry touch, and help keep powders and emulsions feeling lighter on skin.
Binder
Helps hold solid ingredients together to form cohesive tablets, compacts, or sticks, improving pressability, integrity, and wear of the finished product.
Bulking agent
Increases mass/volume to build structure and improve handling, commonly used to adjust feel, spread, and cost-in-use without acting as a primary active.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
