Zinc

Chemical Compounds

Also: Zn, zinc ion

CAS: 7440-66-6

Molecular weight: 65.38 Da

Solubility: Complexed with humic/fulvic acids in peat

Concentration in peat: 10–200 ppm, variable by source

Zinc is a trace mineral present in peat as complexes with humic and fulvic acids. It is one of the most important minerals for skin health, playing essential roles in cell division, immune function, wound healing, and inflammatory regulation.

Form in Peat

Present as Zn²⁺ chelated by humic and fulvic acid functional groups. The chelated form enhances bioavailability compared to free zinc ions, potentially improving transdermal absorption during peat bath treatments.

Cosmetic Relevance

Zinc is widely recognized in dermatology for wound healing, acne management, and anti-inflammatory effects. Its presence in peat adds to the mineral delivery profile of balneotherapy. Zinc-enriched peat from specific sources may be particularly relevant for acne-prone or wound-healing applications.
