Cosmetic Grade Hydroxyl Lanolin（CAS 68439-49-6）
Hydroxyl Lanolin (CAS 68439-49-6) is a hydrophilic modified lanolin derivative modified by hydroxyl grafting reaction on natural refined lanolin. Compared with ordinary crude lanolin, it improves water dispersibility, reduces stickiness and skin allergy risk greatly. This cosmetic grade hydroxyl lanolin adopts deodorization and decolorization refining process, low impurity, stable emulsifying and moisturizing capacity. It is a mild multi-functional emollient, widely approved for global daily cosmetic addition, steadily supplied for B2B cosmetic factories, baby care brands and hair care formulation manufacturers worldwide.
Key Benefits
• Improved hydrophilicity: Water dispersible, easier emulsification than common natural lanolin
• Low hypoallergenic property: Modified purification, lower irritation than crude lanolin
• Strong skin barrier repair: Supplement cutaneous lipid, relieve dry chapped skin efficiently
• Moderate thickening effect: Stabilize cream emulsion system, prevent formula delamination
• Global cosmetic compliance: Approved for adult and infant skincare commercial use
• Fine skin feel: Low greasiness, non-sticky after skin absorption
Applications
• Dry Skin Skincare: Barrier repair cream, anti-dry body lotion, winter moisturizing balm
• Lip Care Products: Moisturizing lip balm, anti-crack lip gloss, lip primer base oil
• Gentle Infant Care: Baby moisturizing ointment, newborn diaper rash repair cream
• Hair Care Series: Anti-frizz hair conditioner, dry hair repair essence oil
• Special Emulsion Raw Material: Low-irritation cosmetic emulsifier, formula stabilizer
