Formulation view O/W balm containing petrolatum, paraffin, cholesterol, and ceramide, combined with oleic and palmitic acids. Targets barrier repair and maximum occlusion for severely dry or eczema-prone skin. Formulator's note: the high load of mineral oils and waxes demands robust anionic thickener (Carbomer) neutralization to ensure gel stability and prevent lipid separation.

Ingredients explained
- Petrolatum
- Mineral oil occlusive and antistatic; requires full refining history to ensure absence of potential carcinogens.
- Aqua
- Solvent, main base; microbial control is critical
- Paraffin
- Paraffin wax for occlusion/viscosity control; inert/safe, may affect breathability
- Paraffinum Liquidum
- Mineral oil occlusive; high moisture retention but heavy feel, moderate comedogenicity, caution for acne-prone skin.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Sorbitan Oleate
- Non-ionic emulsifier for oil-in-water systems; plant-derived, check oxidative stability
- Copernicia Cerifera Wax
- High-melting plant wax; thickener and abrasive for exfoliation or texture, high load may clog
- Cholesterol
- Cholesterol; barrier repair lipid mimicking stratum corneum; often blended with ceramides, plant or fermentation source.
- Ceramide 6
- Not decoded yet
- Oleic Acid
- Oleic acid for emolliency/emulsification; high levels may increase skin penetration
- Palmitic Acid
- Palmitic acid for emulsification/emollient; solid fat, high melting point, occlusive.
- Tromethamine
- pH adjuster, alkaline; precise dosing required
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
