Lanolin

Food additives Europe numbers: E913

Lanolin is a natural substance derived from sheep's wool [1]. It's not exactly a medication, but rather a waxy oil with various applications in skincare and health products. Here's a breakdown of its properties and uses:

Properties:

• Moisturizing: Lanolin mimics the natural oils (sebum) produced by human skin. This allows it to trap water in the skin, keeping it hydrated and supple [2, 3].
• Emollient: Lanolin soothes and softens dry, rough, or irritated skin [2].
• Protective: It can form a barrier on the skin, protecting it from environmental irritants and promoting healing [2].

Uses:

• Treating dry skin: Lanolin is a common ingredient in moisturizers, lotions, and creams for dry, itchy, or cracked skin [2].
• Diaper rash relief: Lanolin-based ointments can help soothe and protect irritated skin from diaper rash [2].
• Protection for breastfeeding mothers: Lanolin can be applied to nipples to prevent soreness and cracking caused by breastfeeding [2].
• Wound healing: Some ointments containing lanolin may be used to promote wound healing due to its protective and moisturizing properties [4].
• Other applications: Lanolin can also be found in lip balms, cosmetics, and some topical medications [1].

Things to consider:

• Lanolin allergy: While uncommon, some people may be allergic to lanolin, especially those with wool allergies [2]. A patch test is recommended before using a new lanolin product.
• Greasiness: Lanolin can feel greasy on the skin, so look for products with lighter formulations if this is a concern.
