In plain English

TEA-Stearate is a man-made ingredient that helps oil and water mix together in skincare products. It is often used in foaming cleansers and creamy lotions to give them a nice texture and help them spread easily. However, because it can strip natural oils, it might leave dry or sensitive skin feeling tight or irritated.

Quick decision guide

Useful, but context matters

TEA-Stearate can be useful, but watch for some irritation potential.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging TEA-Stearate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

TEA-Stearate is a salt formed from triethanolamine (a pH adjuster) and stearic acid (a fatty acid). It acts as an emulsifier and surfactant, meaning it helps blend water and oil and can create foam.

How it works

In a product, TEA-Stearate reduces the surface tension between water and oil, allowing them to mix into a stable cream or lotion. In cleansers, it helps lift dirt and oil from the skin so they can be rinsed away.

Pros

Effective emulsifier

Helps create smooth, stable creams and lotions that feel pleasant on the skin.

Good foaming agent

Produces a rich lather in cleansers, which many people find satisfying and effective for removing surface oil.

Cons and cautions

Potential for dryness

Can strip the skin's natural moisture barrier, leading to tightness or flaking, especially in dry or sensitive skin types.

Irritation risk

At higher concentrations or in leave-on products, it may cause redness or stinging for those with reactive skin.

Best for

  • People with normal to oily skin who enjoy foaming cleansers
  • Those using rinse-off products like facial washes

Use caution if

  • Individuals with dry, sensitive, or eczema-prone skin
  • Anyone looking for a purely natural skincare routine

Usage tips

Use TEA-Stearate products mainly as rinse-off cleansers rather than leave-on creams if you have sensitive skin.
Follow with a moisturizer to replenish hydration after using a TEA-Stearate cleanser.
Patch test new products containing TEA-Stearate on a small area of skin before full use.

Safety summary

TEA-Stearate is generally safe for most people in rinse-off products at low concentrations. However, it can be drying or irritating for sensitive skin, and some individuals may prefer gentler alternatives.

Research notes

Studies on triethanolamine (the base component) indicate low acute toxicity and skin irritation at typical cosmetic levels. The CIR panel concluded it is safe as used, but long-term high exposure data is limited.

Common label clues

Typical concentration
Typically 1–5% in rinse-off products; lower in leave-on formulas
Regulatory status
Approved for use in cosmetics by the FDA and the European Commission within concentration limits. The Cosmetic Ingredient Review (CIR) panel has reviewed triethanolamine and its salts, noting low irritation at typical use levels.
Common uses
Cleansers, Facial washes, Creams, Lotions
Environmental note
TEA-Stearate is synthetic and may not be biodegradable in all conditions. It is not typically associated with significant environmental concerns at low concentrations.

Good to know

  • TEA-Stearate is sometimes listed simply as 'Triethanolamine Stearate' on labels.
  • It is commonly found in bar soaps and cream cleansers for its foaming and thickening properties.
