Hydroxypropyl Starch Phospate ●
TL;DR. This ingredient is primarily a texture modifier and absorbent, used to thicken water-based formulas, reduce greasiness, improve slip, and give creams, gels, powders, and makeup a smoother feel.
What does Hydroxypropyl Starch Phospate do in a cosmetic formula?
This ingredient is primarily a texture modifier and absorbent, used to thicken water-based formulas, reduce greasiness, improve slip, and give creams, gels, powders, and makeup a smoother feel.
Is Hydroxypropyl Starch Phospate clean?
From a clean-beauty perspective, it is generally well tolerated, non-sensitizing, and not a common restricted-list concern. The main review point is processing quality, since residual reagents from chemical modification should be controlled by supplier specifications.
Is Hydroxypropyl Starch Phospate sustainable?
This material is typically derived from plant polysaccharides, often from food-crop sources, and is expected to biodegrade more readily than persistent synthetic film-formers. Its footprint depends on crop sourcing, agricultural inputs, and the chemistry used to modify the base material.
Is Hydroxypropyl Starch Phospate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulations when made from approved plant-derived feedstocks and compliant modification chemistry. Its Green Chemistry profile is favorable because it uses renewable carbon and provides texture and absorbency without persistent silicone or fluorinated materials.
How does Hydroxypropyl Starch Phospate work chemically?
This compound is a chemically modified plant polysaccharide with it substitution and phosphate crosslinking, which improves swelling, viscosity control, and stability versus the native polymer. It is commonly used around 0.5% to 5% depending on whether the goal is sensory improvement, oil absorption, or aqueous thickening, and it is broadly compatible across typical cosmetic pH ranges.
