Erythritol

Erythritol, a four-carbon sugar alcohol of natural origin, is a moisturizer with unique cooling properties upon dissolution. In cosmetics, it provides a fresh and light feeling on the skin, hydrates without stickiness, and synergizes with other polyol moisturizers.

What is it?

Erythritol (INCI: Erythritol) — polyol, molecular weight ~122 Da. Well soluble in water. Natural origin (fermentation). Unique property: high endothermicity of dissolution → cooling sensation upon contact with skin (endothermic reaction absorbs heat). Functions in cosmetics: moisturizer (4 hydroxyl groups), cooling agent (milder than menthol), stabilizer for preservatives, cryoprotectant. Safe: not fermented by oral bacteria (used in the food industry as a non-cariogenic sugar substitute).

Cooling mousses and gels (for legs, after sun exposure, sports cosmetics), refreshing toners and mist sprays, men's after-shave products, summer cosmetics.

Key Benefits

✦
Fresh cooling sensation without menthol
Erythritol absorbs heat upon dissolution on the skin (endothermic reaction) → feeling of coolness. Advantage over menthol: cooling effect is milder, without irritation, suitable for sensitive skin and around the eyes. Does not cause a burning sensation. Ideal for: foot products after prolonged walking, cooling masks, after-sun products, men's after-shave tonics.
◈
Soft hydration without stickiness
Erythritol is a hygroscopic polyol: 4 hydroxyl groups attract water. But less hygroscopic than glycerin → less sticky on the skin. "Clean finish": after application, the skin feels hydrated and fresh, without residues. Especially popular in light summer formulas, where "zero residue" and freshness are important. Synergy with glycerin: an effective moisturizing pair without stickiness.
✧
Antioxidant potential and cell protection
Studies have shown that erythritol has antioxidant activity: neutralizes hydroxyl radicals OH• (similar to mannitol, but weaker). Protects cells from oxidative stress: potential role in anti-aging formulas. Additionally: preserves the stability of preservatives and actives in the formula. Cryoprotective properties: protects cells from damage during cooling.

Erythritol: a small molecule with a big effect

Erythritol is the smallest polyol in cosmetics (C4, MW 122). Smaller molecule → better penetration into the SC. Unique cooling effect: endothermicity of dissolution -43 J/g (for comparison: sorbitol -111 J/g, but in water, not on skin; in the context of skin, erythritol provides a clear cooling sensation). Non-toxic, of natural origin, COSMOS-compatible. Vegan. Suitable for oral-care products (non-cariogenic).
