Common Name(s): Peg-24 lanolin,polyoxyethylene-24 lanolin,ethoxylated lanolin-24

DESCRIPTION

What It Does: Conditions and moisturizes skin deeply while helping oil and water blend in formulas.

Why It's Used: Peg-24 ethoxylation of whole lanolin (not just fatty acids) provides higher molecular weight conditioning with hlb ~13–14 for o/w emulsification.

How It Works: Whole lanolin ethoxylation at 24 eo; hlb ~13–14; lanolin wax esters contribute outstanding skin conditioning; o/w emulsification capability.

Typically Found In: Rich emollient lotions,o/w emulsions,conditioning skin care,protective hand creams

TECHNICAL DETAILS

Primary Category: Functional ingredient – emulsifier

Secondary Functions: Skin conditioning,emollient

Application Areas:

Typical Concentration Range: 0.5%–5%

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: Whole lanolin from sheep wool; eo from petrochemical. [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

Sensitivity Concerns: Rare lanolin sensitization; generally well tolerated.

Safe for Sensitive Skin: Conditional – rare lanolin allergy

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile. ewg score: 1–3.

Works Well With: Peg-based emulsifiers,conditioning agents,humectants,emollients

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Peg-24 lanolin ethoxylates the whole lanolin complex (wax esters, free alcohols, fatty acids) at once; this provides a richer skin conditioning profile than lanolin fatty acid ethoxylates alone; hlb ~13-14.
