Key Ingredients

Ingredients Details
Paraffin
Common Name(s): Mineral oil/paraffin,petroleum hydrocarbon emollient,occlusive barrier
CAS Number: N/a
DESCRIPTION
What It Does: Forms an occlusive lipid film reducing tewl, softens and smooths skin, and provides a long-lasting emollient effect from the hydrocarbon film's low volatility and high stability.
Why It's Used: The most extensively safety-tested cosmetic emollient โ cosmetic-grade mineral oil has a 80+ year safety record with zero documented systemic absorption or sensitisation concerns. its inertness makes it the reference standard for hypoallergenic baby care.
How It Works: Linear and branched c15โc40 paraffin hydrocarbons form a non-polar surface film with water contact angle ~0ยฐ (spreads on skin). the film reduces tewl by 40โ60% through physical occlusion of the sc surface; the inert hydrocarbon chains have no biological interaction with skin proteins explaining the exceptional safety and non-sensitising profile.

SCIENTIFIC NOTE
Petrolatum's wound healing mechanism (moist wound healing) was first systematically studied by george winter (1962) and demonstrated that wounds heal 2ร faster under occlusion than air-exposed. all subsequent wound dressings and occlusive skin treatments are based on this fundamental finding, with petrolatum remaining the most effective occlusive agent 60 years later.
