PEG-30 DIPOLYHYDROXYSTEARATE ●
TL;DR. This ingredient is primarily a water-in-oil emulsifier, helping disperse water droplets evenly inside an oil phase. It is often used in creams, sunscreens, and makeup where a rich, water-resistant emulsion is needed.
What does PEG-30 DIPOLYHYDROXYSTEARATE do in a cosmetic formula?
This ingredient is primarily a water-in-oil emulsifier, helping disperse water droplets evenly inside an oil phase. It is often used in creams, sunscreens, and makeup where a rich, water-resistant emulsion is needed.
Is PEG-30 DIPOLYHYDROXYSTEARATE clean?
From a clean-beauty perspective, it has friction because it is made through ethylene oxide based chemistry and may be scrutinized for trace processing residues such as 1,4-dioxane. It is generally considered low-irritation in finished formulas when properly purified.
Is PEG-30 DIPOLYHYDROXYSTEARATE sustainable?
This material is typically partly petrochemical-derived and partly fatty-acid-derived, often from castor or other vegetable oil sources. Its biodegradability is less straightforward than simple plant oils or fatty alcohols, and the synthetic polyether portion lowers its sustainability profile.
Is PEG-30 DIPOLYHYDROXYSTEARATE COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic standards because ethoxylated materials are excluded. From a Green Chemistry view, it is compromised by petrochemical input and residue-management needs, even though it can support stable emulsions at low use levels.
How does PEG-30 DIPOLYHYDROXYSTEARATE work chemically?
This molecule is a nonionic polymeric ester with a hydrophilic polyether segment and bulky hydroxylated fatty chains, giving it strong interfacial film formation for water-in-oil systems. Typical use is often around 1 to 5 percent, and it is broadly stable across cosmetic pH ranges because it is nonionic rather than charge-dependent.
