Oryza Sativa Starch Starch) ●
TL;DR. This ingredient is used as an absorbent, mattifying texture modifier, and bulking agent in powders, creams, deodorants, and makeup. It helps reduce greasiness, improve slip, and give formulas a softer, drier skin feel.
What does Oryza Sativa Starch Starch) do in a cosmetic formula?
This ingredient is used as an absorbent, mattifying texture modifier, and bulking agent in powders, creams, deodorants, and makeup. It helps reduce greasiness, improve slip, and give formulas a softer, drier skin feel.
Is Oryza Sativa Starch Starch) clean?
From a clean-beauty perspective, it is generally well tolerated and has little restricted-list friction. The main practical note is inhalation management in loose powders, where particle size and product format matter.
Is Oryza Sativa Starch Starch) sustainable?
This material is plant-derived, renewable, and readily biodegradable. Its footprint depends on agricultural practices, water use, and crop-region methane management, but the ingredient itself does not raise persistence concerns.
Is Oryza Sativa Starch Starch) COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic frameworks when sourcing and processing meet the standard. It aligns well with Green Chemistry because it can come from renewable feedstock, requires relatively simple processing, and biodegrades readily.
How does Oryza Sativa Starch Starch) work chemically?
The molecule is a granular carbohydrate polymer made mainly of amylose and amylopectin, which explains its oil-absorbing feel, soft-focus texture, and thickening behavior when hydrated and heated. Typical use levels range from about 1 to 10 percent in emulsions and higher in anhydrous or loose powder systems, with stability best in dry formats or emulsions where microbial control is handled by the full preservative system.
