Science
Mechanism of Action
This ingredient creates an occlusive barrier on the skin, reducing TEWL by forming a highly hydrophobic, water-resistant film. Its unique acetylation process enhances hydrophobicity, promoting a smooth, non-tacky feel by lubricating the stratum corneum.

Key findings
- 01 Recent cosmetic usage surveys (2022) indicate safety across 0.02% to 6.3% concentrations, reaffirming low sensitivity based on historical data from 1980 and 2005.
- 02 Undiluted animal dermal irritation tests showed related Acetylated Lanolin derivatives had a Primary Irritation Index (PII) of 1.62 (mildly irritating), indicating good tolerability in formulations.

Stability
It is highly hydrophobic and stable in cold mineral oil, requiring emulsification in water-based systems. Store in sealed containers away from heat and light to prevent oxidative degradation.
Conflicts
- Water-based systems (requires emulsification)
- Highly polar systems
Safety
Safety Profile
Recognized as safe by the CIR Expert Panel up to 7.5%, exhibiting low acute toxicity and non-sensitizing properties. However, historical reports link some lanolin derivatives to potential comedogenicity and rare sensitivity to lanolin alcohols.

Verdict
Acetylated Lanolin Ricinoleate is a valuable emollient, offering significant hydration and skin conditioning, particularly for dry and sensitive skin, though its high comedogenicity should be considered for precision formulations.
