What Is Laureth-6 Citrate?
Laureth-6 Citrate is a synthetic surfactant made by reacting naturally occurring lauryl alcohol with about six units of ethylene oxide, then neutralizing the resulting laureth-6 with citric acid to form a citrate ester. This structure gives the molecule a water-loving (hydrophilic) ethoxylated chain and an oil-loving (lipophilic) lauryl tail, allowing it to interact with both water and skin oils.
Surfactants like laureth-6 citrate became popular in the 1970s when formulators sought milder, pH-balanced alternatives to traditional soaps. Its balanced charge and citric acid component make it gentler than many sulfate-based cleansers while still offering effective soil and oil removal.
Manufacturing starts with plant-derived fatty alcohols from coconut or palm kernel oil. These alcohols undergo ethoxylation, a carefully controlled reaction with ethylene oxide gas. The resulting laureth-6 is then esterified with food-grade citric acid. Quality control ensures the average of six ethoxy units, low free ethylene oxide content and consistent purity.
You are most likely to find laureth-6 citrate in facial cleansers, micellar waters, body washes, baby shampoos, makeup removers and exfoliating scrubs. It also appears in masks and wipe-off products where a gentle but thorough rinse-away agent is needed.
Laureth-6 Citrate’s Cosmetic Benefits/Uses
The main role of laureth-6 citrate in cosmetics is cleansing. Its amphiphilic structure lifts dirt, excess sebum, sunscreen and makeup from the skin so they can be rinsed away with water. Because it is milder than many anionic surfactants it helps formulas create a soft, low-irritation lather that leaves skin feeling clean but not stripped of moisture.
Who Can Use Laureth-6 Citrate
Because it is a mild, pH-balanced cleansing agent, laureth-6 citrate generally suits all skin types including oily, combination, dry and sensitive skin. Its ability to lift excess oil without stripping moisture makes it comfortable for acne-prone and mature complexions as well. People with very compromised or eczema-prone skin should still check formulas for added fragrance or exfoliating acids that could increase irritation.
The ingredient is manufactured from plant-derived fatty alcohols and citric acid, so in its raw form it is suitable for both vegans and vegetarians. Finished products that contain it can still be non-vegan if other animal-derived ingredients are present, so label reading is key.
Current safety data show no specific risks for pregnant or breastfeeding women when laureth-6 citrate is used topically in rinse-off products. It has minimal skin penetration and is widely considered low risk. This is not medical advice, so anyone who is pregnant or nursing should review their skincare routine with a healthcare professional to be sure it meets their individual needs.
Laureth-6 citrate does not increase photosensitivity and has no known effect on hair color treatments, self-tanners or common actives like retinoids and vitamin C.
Potential Side Effects/Adverse Reactions
Reactions to topical laureth-6 citrate differ from person to person. The effects listed below are only potential issues and are unlikely for most users when the ingredient is properly formulated and used as directed.
- Mild skin irritation or redness, especially on very sensitive or broken skin
- Transient stinging or burning if applied to abraded areas
- Dryness or tightness when used in a high-foaming cleanser without sufficient moisturizers
- Allergic contact dermatitis in individuals sensitized to ethoxylated surfactants
- Eye irritation if the product is accidentally rubbed into the eyes
If you experience any of the above reactions stop using the product and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 1/5 (very low)
Laureth-6 Citrate is a water-soluble surfactant that is usually rinsed off within seconds, leaving little to sit on the skin and clog pores. Its molecular structure is too large to settle inside follicles and it lacks heavy oils or waxes that normally raise comedogenicity scores.
Suitable for acne-prone skin: Yes, most people who are prone to breakouts can use products containing this ingredient without an increased risk of clogged pores.
Because it is typically paired with humectants and used at low concentrations in cleansers the real-world risk of pore blockage is minimal. Residual film is further reduced when the formula includes water-softening agents or is followed by a toner.
Summary
Laureth-6 Citrate is a gentle synthetic surfactant that lifts dirt, makeup and excess oil so they can be rinsed away with water. Its balanced hydrophilic and lipophilic segments let it create a mild lather that cleans without stripping skin of moisture.
While not as well known as heavy hitters like sodium laureth sulfate it quietly appears in many facial cleansers, micellar waters and baby washes where formulators need a softer touch. Its versatility and plant-derived feedstocks keep it in steady, if understated, demand.
Current safety data rate it low risk for irritation or sensitization when used as directed, especially in rinse-off products. As with any new skincare product it is smart to patch test first to make sure your individual skin reacts well.
