What Is Laureth-7 Tartrate?
Laureth-7 Tartrate is a synthetic ingredient made by linking ethoxylated lauryl alcohol (a substance derived from coconut or palm oil) with tartaric acid, a fruit-based acid commonly found in grapes. The name “7” points to the average number of ethylene oxide units attached to the lauryl alcohol chain, which helps the molecule mix oil and water. First explored in the 1970s as brands looked for milder ways to clean skin and hair, it soon earned a spot in modern formulas thanks to its gentle touch and good foam. Production starts with plant-sourced lauryl alcohol that goes through ethoxylation, then esterification with tartaric acid to form the final tartrate. You will most often see Laureth-7 Tartrate in face cleansers, micellar waters, body washes, shampoo and sometimes in makeup removers where a soft yet effective cleanse is needed.
Laureth-7 Tartrate’s Cosmetic Benefits/Uses
This ingredient serves mainly as a cleansing agent that lifts away dirt, oil and makeup while keeping formulas mild and easy to rinse.
Who Can Use Laureth-7 Tartrate
Because Laureth-7 Tartrate is a mild cleansing agent it is generally suitable for oily, combination, normal and mildly dry skin types. Those with very dry or compromised skin barriers may want to pair it with richer moisturizers, as any surfactant can contribute to a feeling of tightness if used in high amounts or left on for long periods. Its low irritation profile makes it a frequent pick for sensitive skin formulas, though individual tolerances can vary.
The ingredient is typically produced from plant sourced fatty alcohols and synthetic processing aids, with no animal derived components, so products using it are usually considered vegan and vegetarian friendly. Always confirm with the specific brand for full supply chain transparency.
No data suggest that Laureth-7 Tartrate poses a special risk for women who are pregnant or breastfeeding when used topically in rinse off or leave on products. This is not medical advice; anyone who is expecting or nursing should discuss all personal care products with a qualified healthcare provider to be extra safe.
The molecule is not known to cause photosensitivity, so it does not make skin more prone to sunburn. Standard daily sun protection is still recommended for overall skin health.
Potential Side Effects/Adverse Reactions
Side effects and reactions to topical Laureth-7 Tartrate vary from person to person. The points below list potential issues yet most users will not experience them when the ingredient is properly formulated and used as directed.
- Mild skin irritation such as redness, itching or a stinging sensation
- Excessive dryness or tightness, especially in very dry or eczema prone skin
- Eye irritation or tearing if the product accidentally gets into the eyes
- Rare allergic contact dermatitis presenting as a rash or hives
- Increased transepidermal water loss when used in highly concentrated rinse off formulas without follow up moisturization
If any of these reactions occur stop using the product and consult a healthcare professional or dermatologist for further guidance.
Comedogenic Rating
Rating: 1/5. Laureth-7 Tartrate is highly water soluble and rinses off easily, leaving little to no residue that could block pores. It is classed as a mild non-occlusive surfactant, so it does not sit on the skin in the same way heavy oils or waxes do. Because of this low residue profile, it is generally considered suitable for people who are prone to acne or breakouts. As with any cleansing ingredient, pore-clogging risk can rise if the finished formula contains richer emollients or if the product is not rinsed away properly.
Summary
Laureth-7 Tartrate is a gentle surfactant that lifts away dirt, oil and makeup while helping water mix with oily grime so everything rinses off cleanly. Its balanced structure provides effective cleansing without harshness, which is why you will spot it in face washes, micellar waters and shampoos that promise a soft feel.
The ingredient is moderately popular. It is not as common as classic sulfates but it appears frequently in modern mild cleansers where formulators want good foam with less irritation.
Current safety data shows it is low risk for irritation or sensitization when used at normal levels in rinse-off or leave-on products. Even so, everyone’s skin is different, so it is smart to do a small patch test whenever trying a new product that lists Laureth-7 Tartrate near the top of the ingredient list.
