Zea Mays Starch/Corn Starch ●
TL;DR. This ingredient is used as an absorbent, bulking agent, and texture modifier, especially in powders, dry shampoos, deodorants, and mattifying products. It helps take up oil and moisture while giving formulas a soft, dry feel.
What does Zea Mays Starch/Corn Starch do in a cosmetic formula?
This ingredient is used as an absorbent, bulking agent, and texture modifier, especially in powders, dry shampoos, deodorants, and mattifying products. It helps take up oil and moisture while giving formulas a soft, dry feel.
Is Zea Mays Starch/Corn Starch clean?
It is generally well tolerated and has little clean-standard friction when used in topical products. The main practical consideration is fine-particle dust in loose powders, which can be irritating if inhaled.
Is Zea Mays Starch/Corn Starch sustainable?
This material is plant-derived, renewable, and readily biodegradable. Its sustainability profile depends mostly on agricultural practices, water use, and whether the supply chain uses certified organic or non-GMO sourcing.
Is Zea Mays Starch/Corn Starch COSMOS-approved?
It is permitted under COSMOS-natural and can contribute to COSMOS-organic content when the agricultural source is certified organic. It aligns well with Green Chemistry principles because it can be made through relatively simple physical processing from renewable feedstock and breaks down readily in the environment.
How does Zea Mays Starch/Corn Starch work chemically?
This is a granular alpha-glucan polysaccharide material composed mainly of amylose and amylopectin, not a single defined molecule. It is insoluble in cold water, swells with heat, often appears at about 1 to 30% depending on format, and water-containing formulas need appropriate preservation because hydrated carbohydrate-rich materials can support microbial growth.
