What is it?

Ectoin (1,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid) is an osmotically active substance (compatible solute) synthesized by halophilic and thermophilic bacteria for survival in extreme conditions. In cosmetics, it is obtained through the fermentation of Halomonas elongata. Trademark Ectoin® (Bitop AG). Concentration in cosmetics: 0.1–1%. Stable over a wide range of pH and temperatures.

An ingredient for protection against pollutants, thermal stress, and UV damage. Popular in urban cosmetics and products for sensitive skin. Often combined with antioxidants and protective components.

Key Benefits

✦

Protection of cells from stress and pollutants

Ectoin forms a protective hydrated shell around cell membranes and proteins — a physical barrier against pollutants (PM2.5, heavy metals), thermal stress, and osmotic changes. Clinical studies by Bitop show a 47% reduction in TRPV1 activation (pain/heat sensor) — decreasing the reactivity of sensitive skin.

◈

Protection from UV damage and photoaging

Protects cells from UVA-induced oxidative stress by stabilizing membranes and proteins. Reduces the secretion of Matrix Metalloproteinase-1 (MMP-1) — a collagen-degrading enzyme — after UV exposure. Complements SPF protection but does not replace it.

✧

Strengthening the barrier and moisturizing

Stimulates the synthesis of lipids in the stratum corneum and increases NMF (natural moisturizing factor) content. Reduces TEWL and improves hydration. Effective for atopic dermatitis and dry, reactive skin.

Ectoin and Hydroxyectoin

Hydroxyectoin is a hydroxylated form of ectoin with even stronger thermal protection. Some formulas contain both. Ectoin® is a patented trademark of Bitop AG; check dosage — effective concentration from 0.1%.
