Waxes and Lipids

Chemical Compounds
Also: peat lipids, peat waxes, cuticular waxes
Molecular weight: Varies
Solubility: Hydrophobic — extractable with organic solvents
Concentration in peat: 1–8% of dry mass

Waxes and lipids in peat derive from the original plant material — cuticle waxes, membrane lipids, and resinous compounds from sphagnum and other bog plants. They are modified during decomposition but retain their hydrophobic character.

Types

Include long-chain fatty acids, fatty alcohols, sterols, terpenoids, and wax esters. The lipid profile varies by peat type and plant source. Sphagnum-derived peat has a distinct lipid signature compared to sedge or woody peat.

Cosmetic Relevance

The lipid fraction contributes emollient and occlusive properties to whole-peat applications. In face masks and body wraps, peat lipids help seal moisture into the skin. In extracted peat preparations, the lipid fraction may be separated or retained depending on the desired product characteristics.
