Triethylamine Hexylsalicylate

INCI: Triethylamine Hexylsalicylate

A synthetic pH adjuster that helps stabilize salicylate ingredients, but may cause irritation in sensitive skin.

In plain English

Triethylamine hexylsalicylate is a lab-made ingredient that helps control the acidity of a product and keeps certain active ingredients stable. It is a salt formed from triethylamine (a pH adjuster) and hexylsalicylate (a form of salicylic acid). Because it contains a salicylate, it may have mild exfoliating or anti-inflammatory properties, but its main job is to keep the formula balanced and effective. It is used in very small amounts, but people with sensitive or reactive skin might experience irritation.

Quick decision guide

Read the cautions before using

Triethylamine Hexylsalicylate 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 Triethylamine Hexylsalicylate.
  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

A synthetic salt created by combining triethylamine (an organic base used to adjust pH) with hexylsalicylate (a salicylic acid derivative). It is used primarily as a pH adjuster and stabilizer in cosmetic formulations.

How it works

Triethylamine hexylsalicylate works by neutralizing the acidity of other ingredients, helping the product maintain a skin-friendly pH. The hexylsalicylate portion may also provide mild exfoliation by encouraging the shedding of dead skin cells, similar to salicylic acid, but in a gentler, buffered form.

Pros

Stabilizes formulas

Helps keep the product's pH balanced, which extends shelf life and ensures other active ingredients work as intended.

Gentle exfoliation potential

The hexylsalicylate component may offer mild exfoliation benefits similar to salicylic acid, but in a buffered form that is less harsh on the skin.

Cons and cautions

Irritation risk

Triethylamine itself can be a skin irritant, and the salicylate may cause redness or stinging in sensitive individuals, especially at higher concentrations.

Limited research

There is not a large body of peer-reviewed studies specifically on triethylamine hexylsalicylate in cosmetics, so its long-term safety profile is less established than more common pH adjusters.

Best for

  • People with oily or acne-prone skin looking for gentle exfoliation
  • Those using stabilized salicylate products for anti-aging

Use caution if

  • Individuals with known salicylate allergy or sensitivity
  • Those with very sensitive or easily irritated skin

Usage tips

Always patch test a new product containing this ingredient on a small area of skin before full use.
If you have sensitive skin, look for products where this ingredient appears near the end of the ingredient list, indicating a lower concentration.

Safety summary

Generally considered safe for most skin types at low concentrations, but can cause irritation in sensitive individuals. Those with salicylate sensitivity should avoid it. More research is needed on long-term use.

Research notes

Limited specific studies on triethylamine hexylsalicylate itself. Its safety is inferred from studies on its components (triethylamine and salicylates). The Cosmetic Ingredient Review (CIR) has evaluated related salicylates and found them safe at low concentrations.

Common label clues

Typical concentration
Very low, typically under 1%
Regulatory status
Approved for use in cosmetics in the EU and US, but subject to concentration limits due to potential irritation. Always follow local regulations.
Common uses
Sunscreens, Anti-aging creams, Serums
Environmental note
Triethylamine hexylsalicylate is synthetic and may not be biodegradable. Its environmental impact is not well-studied, but it is used in very small amounts in rinse-off and leave-on products.

Good to know

  • Triethylamine hexylsalicylate is sometimes used in sunscreens to improve the stability of UV filters.
  • It is not the same as pure salicylic acid and is generally considered milder, but still warrants caution for those with aspirin allergies.
