In plain English

Laureth-7 Tartrate is a mild cleansing ingredient that helps water mix with oil and dirt so they can be rinsed away. It's made from lauryl alcohol (from coconut or palm oil) and tartaric acid (a natural fruit acid). Because it's gentle, it's often used in products for sensitive skin that need to clean without causing dryness or irritation.

Quick decision guide

Useful, but context matters

Laureth-7 Tartrate 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Laureth-7 Tartrate.
  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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

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

Laureth-7 Tartrate is a semi-synthetic surfactant created by reacting lauryl alcohol with ethylene oxide to form laureth-7, then esterifying it with tartaric acid. This gives it both water-loving and oil-loving properties, allowing it to act as a mild cleanser and emulsifier.

How it works

In a cosmetic product, Laureth-7 Tartrate reduces the surface tension between water and oil, helping to lift dirt, sebum, and makeup from the skin so they can be rinsed away. Its tartrate group adds extra mildness, making it less likely to disrupt the skin's natural moisture barrier compared to harsher sulfates.

Pros

Very gentle on skin

Laureth-7 Tartrate is designed to clean without stripping the skin's natural oils, making it ideal for daily use on sensitive or dry skin.

Good for combination formulas

It helps blend water and oil phases in a product, improving texture and stability without needing harsh solvents.

Cons and cautions

Lower foam than sulfates

If you enjoy a rich, bubbly lather, this ingredient may feel less satisfying compared to stronger surfactants like sodium lauryl sulfate.

Not fully natural

Because it undergoes ethoxylation (reaction with ethylene oxide), it is considered semi-synthetic, which may not align with all-natural skincare preferences.

Best for

  • People with sensitive or dry skin
  • Those looking for a mild daily cleanser

Use caution if

  • Individuals seeking a high-foam, sulfate-based cleanser
  • Those who strictly avoid any ethoxylated ingredients

Usage tips

Use in rinse-off products like cleansers and shampoos for best results.
Pair with other mild surfactants to boost cleansing power while maintaining gentleness.
Avoid using in leave-on products unless specifically formulated for that purpose.

Safety summary

Laureth-7 Tartrate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for sensitive skin. As with any ethoxylated ingredient, trace impurities like 1,4-dioxane are possible but are minimized through good manufacturing practices.

Research notes

Research on laureth compounds indicates they are mild surfactants with low skin irritation. While specific studies on Laureth-7 Tartrate are limited, the broader class of alkyl ether carboxylates and tartrate esters is well-documented for gentle cleansing. The Cosmetic Ingredient Review has affirmed the safety of similar laureth ingredients.

Common label clues

Typical concentration
Typically 1-10% in rinse-off products
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed similar laureth compounds and found them safe at typical use levels.
Common uses
Cleansers, Shampoos, Body washes, Facial washes
Environmental note
Laureth-7 Tartrate is biodegradable, but its production involves ethoxylation, which has a moderate environmental footprint. Sourcing of lauryl alcohol from sustainable palm oil can improve its eco-profile.

Good to know

  • Laureth-7 Tartrate is often found in sulfate-free cleansers.
  • The 'laureth' prefix indicates it has been ethoxylated, which can sometimes produce trace amounts of 1,4-dioxane during manufacturing, though reputable brands purify to remove it.
