Solanum Tuberosum (Potato) Starch Modified
What is Solanum Tuberosum (Potato) Starch Modified?
Solanum Tuberosum (Potato) Starch Modified is a chemically or physically altered derivative of starch extracted from potatoes (Solanum tuberosum), used primarily as a thickening agent, stabilizer, and absorbent in skincare formulations. The modification process enhances its stability, texture, and performance in products like creams, lotions, and powders by improving water-binding capacity and resistance to shear forces. It provides a smooth, matte finish and helps control oil and moisture 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.
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.
Binding
Provides cohesion by helping ingredients stick together, improving the strength and integrity of pressed powders, tablets, or solid bars.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
