What Is Tea-Lactate?
Tea-Lactate is the cosmetic name for tris(2-hydroxyethyl)ammonium lactate, a salt made by combining lactic acid, which occurs naturally in milk and fermented foods, with triethanolamine, a common pH-balancing agent. The result is a clear water-soluble liquid that draws moisture to the skin and helps products feel silky. First explored in the late 20th century as chemists searched for gentler alternatives to mineral salts, Tea-Lactate gained popularity when formulators noticed its ability to hydrate without leaving a heavy film.
Production starts with the fermentation of plant sugars to create lactic acid. This acid is neutralized with triethanolamine under controlled temperatures, producing a stable ingredient with a skin-friendly pH. Because it is synthetically refined from renewable plant sources rather than animal milk, it fits well in vegan or “clean beauty” lines.
You will most often see Tea-Lactate in lightweight moisturizers, hydrating serums, overnight masks, refreshing facial mists, anti-aging creams focused on plumping fine lines and body lotions aimed at relieving rough patches. Its versatility also makes it a supporting player in exfoliating treatments where extra moisture offsets potential dryness from acids.
Tea-Lactate’s Cosmetic Benefits/Uses
In formulas Tea-Lactate serves two main purposes that translate into real skin benefits
- Humectant: Attracts water from the environment and the deeper layers of skin to the surface, boosting immediate and long-term hydration. This helps soften rough areas and gives skin a plump smooth look.
- Skin conditioning: Improves the overall feel of a product by making it glide easily while leaving the skin feeling comfortable, not sticky. Regular use can enhance suppleness and support a healthy skin barrier.
Who Can Use Tea-Lactate
Tea-Lactate suits most skin types. Dry and normal skin benefit most from its moisture-drawing talent while oily or combination skin usually tolerates it well since it feels light and non-greasy. Sensitive skin generally does fine because the ingredient has a skin-friendly pH, though anyone with a history of lactic acid sensitivity should proceed with care.
Because the lactic acid in Tea-Lactate is made from fermented plant sugars rather than dairy, the final material is free of animal inputs. This makes it acceptable for vegans and vegetarians.
Current research shows no specific risks for pregnant or breastfeeding women when Tea-Lactate is used on the skin. Still this is not medical advice and anyone who is pregnant or nursing should run their chosen products past a healthcare professional just to be safe.
Tea-Lactate does not increase photosensitivity so it will not make skin more likely to burn in the sun. It also plays well with most other common skincare ingredients including niacinamide, hyaluronic acid and gentle exfoliating acids.
Potential Side Effects/Adverse Reactions
Reactions to Tea-Lactate differ from person to person. The points below outline possible side effects, though most users will not experience them when the ingredient is properly formulated in a product.
- Mild stinging or tingling
- Temporary redness
- Itchiness in very sensitive skin
- Rare allergic contact dermatitis
If any of these effects occur stop using the product and seek advice from a qualified medical professional.
Comedogenic Rating
Rating: 0–1 (very low). Tea-Lactate is a small water-soluble molecule that attracts moisture rather than forming an oily film, so it does not clog pores. It lacks fatty acids or heavy waxes that normally raise comedogenicity. Because of this, it is generally suitable for people prone to acne or breakouts. No additional concerns about pore blockage have been documented in clinical or consumer reports.
Summary
Tea-Lactate works mainly as a humectant and skin-conditioning agent, drawing water into the upper layers of skin and leaving it soft and smooth. Its lightweight texture, compatibility with many actives and plant-derived origin have made it a quiet staple in moisturizers, serums and masks, though it has not reached the headline status of hyaluronic acid or glycerin. Overall safety data are strong, with low irritation potential and virtually no comedogenic risk. As with any new skincare ingredient it is wise to perform a quick patch test before full use, especially if you have highly reactive skin.
