Common Name(s): Peg-75 lanolin,peg-75 lanolin,peg-glyceryl emulsifier,ethoxylated glyceride

CAS Number: N/a

DESCRIPTION

What It Does: Provides o/w emulsification from peg-75 ethoxylation of lanolin glyceride, with hlb ~18 enabling stable oil-in-water formulations with the emollient character of the glyceride contributing skin feel alongside surfactant function.

Why It's Used: Peg-75 lanolin is selected for peg-75 ethoxylated lanolin hlb 18 emulsification — the peg chain length precisely tunes the hlb for o/w emulsion stability while the glyceride lipid moiety provides emollient co-contribution absent from conventional surfactant emulsifiers.

How It Works: Peg-75 chain: ether oxygen h-bonding → water miscibility; lanolin glyceride tail → oil phase anchoring; hlb ~18 → o/w interface stabilisation.

Typically Found In: Emollient formulas,o/w emulsions

SOURCING & ETHICS

Vegan Status: No - animal-derived

Halal Status: Conditional - wool-derived from live shorn sheep; no slaughter involved, but certifier stance varies; sheep-origin documentation required

Source Notes: Plant-derived, synthetic or animal-derived. verify source. [audit 2026-07-29 rev2: wool-derived; certifier stance varies and is not recorded. determination requires shariah-panel sign-off.]

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 1/5 – low; formulation-dependent

Sensitivity Concerns: Non-irritating.

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 emulsifier eo chain length (peg-n) is the primary hlb tuning parameter — incrementing peg-n by 5 increases hlb by approximately 1 unit.
