Compatibility

Works well with:
Glycerin Tocopheryl Acetate Ceramides Cholesterol Fatty Alcohols Hyaluronic Acid

Use caution with:
Strong oxidizing agents High concentrations of ethanol

Hydrogenated Lecithin is broadly compatible with most cosmetic ingredients and is frequently used alongside cholesterol and ceramides to construct lamellar or liposomal delivery systems. Its saturated fatty acid chains give it greater oxidative stability compared to standard lecithin, making it more robust in formulations containing antioxidants or actives. High concentrations of ethanol can disrupt phospholipid bilayer structures, so care should be taken in alcohol-containing formulas.

Formulation notes

Hydrogenated Lecithin is a phospholipid mixture derived by catalytic hydrogenation of lecithin, converting unsaturated fatty acid chains to saturated ones for improved oxidative stability. Formulators use it as an emulsifier, skin-conditioning agent, and liposome-forming ingredient to enhance delivery of actives into the stratum corneum due to its structural similarity to skin lipids. It is generally considered safe and non-irritating, with its plant-derived (typically soy or sunflower) origin making it suitable for 'natural' and 'clean beauty' positioning.
