About

An ethoxylated lanolin acetate (9 mol EO) similar to Laneth-10 Acetate, used as a skin-conditioning emollient with a well-established safety profile.

Laneth-9 Acetate is the acetate of ethoxylated lanolin (9 mol EO) and shares the same CAS number (65071-98-9) with the Laneth-10 variant. It is listed in EU CosIng without restrictions and functions as a non-ionic emollient and skin conditioner. The slightly lower ethoxylation (9 vs 10) gives marginally different physical properties but the safety profile is equivalent. Well tolerated on sensitive skin with no significant irritation or sensitisation at cosmetic use levels.

Skin benefits

  • Emollient and skin conditioning
  • Improves skin softness
  • Good for dry and sensitive skin

Known concerns

  • Rare lanolin-related allergenicity possible
