Common Name(s): Peg-10 glyceryl stearate,peg-10 glyceryl stearate,peg-glyceryl stearate,ethoxylated glyceryl stearate

DESCRIPTION

What It Does: Creates stable oil-in-water emulsions while softening skin, thanks to its stearate fatty acid component. a versatile emulsifier for creams and lotions.

Why It's Used: Peg-10 glyceryl stearate is selected for dual emulsifier-emollient functionality — the peg-10 chain provides hlb 10–11 precision tuning for o/w emulsion stability while the glyceryl stearate moiety contributes lipid-based emolliency absent from conventional non-glyceride peg surfactant emulsifiers.

How It Works: Peg-10 ethoxylate → hydrophilic headgroup; glyceryl stearate tail → oil phase anchoring + skin-feel emolliency; hlb ~10–11 → o/w emulsion stabilization.

Typically Found In: Lotions,creams,o/w emulsions

TECHNICAL DETAILS

Primary Category: Functional ingredient – emulsifier

Secondary Functions: Skin conditioning,barrier support

Application Areas:

Typical Concentration Range: 0.5%–10%

SOURCING & ETHICS

Vegan Status: Conditional - feedstock declaration required

Halal Status: Unverified - feedstock declaration required (plant, animal and petrochemical routes all exist)

Source Notes: Stearate from plant (palm/shea); glycerol plant-derived; eo from petrochemical. [audit 2026-07-29 rev2: origin-dependent: the same inci exists in plant, animal and petrochemical versions and the name does not discriminate. determination requires shariah-panel sign-off.]

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 1/5 – low; stearate-based

Sensitivity Concerns: Generally well tolerated. non-irritating at typical use concentrations.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Excellent safety profile. ewg score: 1.

Works Well With: Humectants,ceramides,actives as carrier

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Peg-glyceryl stearate ethoxylates show dual-function behavior — self-emulsifying at the oil-water interface while simultaneously reducing tewl through glyceride-sc bilayer interaction, making them functionally distinct from simple non-glyceride peg surfactants.
