Cornstarch ●
TL;DR. This ingredient is an absorbent and texture modifier that takes up oil and moisture, reduces tack, and improves slip. It is common in powders, dry shampoos, deodorants, and emulsions where a softer, drier skin feel is needed.
What does Cornstarch do in a cosmetic formula?
This ingredient is an absorbent and texture modifier that takes up oil and moisture, reduces tack, and improves slip. It is common in powders, dry shampoos, deodorants, and emulsions where a softer, drier skin feel is needed.
Is Cornstarch clean?
This ingredient is generally well-tolerated and has little clean-standard friction, with no common restricted-list issues. As with any fine powder, airborne dust can be mechanically irritating if inhaled during use or manufacturing.
Is Cornstarch sustainable?
This material is plant-derived, renewable, and readily biodegradable. Its footprint depends on agricultural practices, including fertilizer use, water demand, and whether the supply is certified organic or non-GMO.
Is Cornstarch COSMOS-approved?
It is permitted under COSMOS natural and organic frameworks when sourced and processed according to the standard, including GMO restrictions. It fits Green Chemistry well because it is renewable, biodegradable, and usually made through relatively simple physical processing.
How does Cornstarch work chemically?
Chemically, it is a high-molecular-weight glucose polymer made mainly of amylose and amylopectin granules, and it is insoluble in cold water but can swell and thicken with heat. Typical use is about 1; 10% for sensory modification in emulsions and higher in anhydrous powders, depending on absorbency and skin-feel targets.
