Ingredient review
TEA-Sorbate
INCI: TEA-Sorbate
TEA-Sorbate is a gentle preservative that helps keep your products fresh, but it may cause mild irritation for very sensitive skin.
In plain English
TEA-Sorbate is a preservative made by combining sorbic acid (a natural compound found in berries) with triethanolamine. Its job is to stop bacteria, yeast, and mold from growing in your skincare products, which helps them stay safe and effective longer. It is considered a milder alternative to some other preservatives, but it can still be slightly irritating for people with very sensitive skin.

Quick decision guide
Useful, but context matters
TEA-Sorbate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging TEA-Sorbate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
TEA-Sorbate is the triethanolamine salt of sorbic acid, a preservative commonly used in cosmetics and personal care products. It appears as a white to off-white powder or crystalline solid and is water-soluble, making it easy to formulate into various product types.
How it works
TEA-Sorbate works by disrupting the cell membranes of microorganisms like bacteria, yeast, and mold. It interferes with their ability to grow and reproduce, thereby preserving the product from spoilage. It is most effective in acidic to neutral pH formulations (typically pH 4.5–6.5).
Pros
Mild preservation
TEA-Sorbate is considered a gentle preservative, making it suitable for products aimed at sensitive skin when used at appropriate concentrations.
Broad-spectrum activity
It effectively inhibits a wide range of microorganisms, including bacteria, yeast, and mold, helping to keep your products safe from spoilage.
Cons and cautions
pH sensitivity
TEA-Sorbate works best in acidic to neutral formulas (pH 4.5–6.5). In higher pH products, its preservative power drops, which could lead to contamination if not balanced with other preservatives.
Potential for mild irritation
Although generally well-tolerated, some people with very sensitive skin may experience mild stinging, redness, or allergic reactions, especially at higher concentrations.
Best for
- People looking for a milder preservative system in their skincare
- Those with normal to combination skin who want reliable preservation without harsh chemicals
Use caution if
- Individuals with known allergies to sorbic acid or triethanolamine
- Those with extremely sensitive or reactive skin who may experience mild stinging or redness
Usage tips
Safety summary
TEA-Sorbate is considered safe for use in cosmetics at typical concentrations. It has low acute toxicity and is not a known carcinogen or reproductive toxin. However, it can cause mild skin irritation or allergic reactions in a small subset of individuals, particularly those with pre-existing sensitivities to sorbic acid or triethanolamine.
Research notes
Research supports the efficacy of sorbic acid and its salts as preservatives against a broad spectrum of microorganisms. Studies indicate low irritation potential compared to some alternatives, though individual sensitivity varies. Regulatory bodies like the Cosmetic Ingredient Review (CIR) have deemed sorbic acid and its salts safe for use in cosmetics at concentrations up to 0.6%.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the EU, USA, and many other regions, with concentration limits typically up to 0.6% as an acid equivalent. Always follow local regulations.
- Common uses
- Cleansers, Moisturizers, Shampoos, Conditioners, Lotions
- Environmental note
- TEA-Sorbate is biodegradable and does not persist in the environment, but its production involves synthetic chemistry. It is not typically associated with significant ecotoxicity.
Good to know
- TEA-Sorbate is often listed on ingredient labels simply as 'TEA-Sorbate' or 'Triethanolamine sorbate'.
- It is not a formaldehyde-releaser, making it a popular choice in 'free-from' formulations.
