What Is Disteareth-5 Lauroyl Glutamate?
Disteareth-5 Lauroyl Glutamate is a silky, oil-in-water friendly ingredient made from a mix of plant-derived fatty alcohols, natural glutamic acid and a controlled amount of ethylene oxide. The fatty part often comes from coconut or palm oils while the glutamic acid is sourced from fermented sugar. These raw materials are blended then gently reacted to form a mild surfactant that marries oil-loving and water-loving pieces in one molecule. The “5” in its name shows the average number of ethylene oxide units attached, which balances solubility and softness.
Its roots trace back to the 1990s when formulators searched for gentler cleansers to replace harsher sulfates. By coupling soothing fatty alcohols with amino acid chemistry they created a versatile compound that conditions skin and hair while lifting dirt. Today manufacturers use efficient, low-temperature processes that limit waste and energy, producing a biodegradable powder or paste that blends easily into finished products.
You will spot Disteareth-5 Lauroyl Glutamate in creamy facial cleansers, hydrating body washes, sulfate-free shampoos, leave-in conditioners, lightweight lotions, sheet masks and even some anti-aging serums where a soft after-feel is desired alongside gentle cleansing.
Disteareth-5 Lauroyl Glutamate’s Cosmetic Benefits/Uses
In formulas this multitasker brings three main perks
- Hair conditioning – coats the cuticle so strands feel smoother, look shinier and resist static without a heavy or greasy residue
- Emollient – softens and moisturizes the skin surface helping creams glide on and leave a velvety touch
- Cleansing – lifts away oils, sweat and makeup while maintaining the skin’s natural barrier making washes feel mild and non-stripping
Who Can Use Disteareth-5 Lauroyl Glutamate
This ingredient is considered friendly for most skin types including dry, normal, combination and oily because it cleans without stripping natural oils and leaves a light conditioning film. Sensitive skin usually tolerates it well thanks to its mild amino-acid base, though anyone with a known allergy to coconuts or corn-derived sugar sources should stay alert.
Disteareth-5 Lauroyl Glutamate is suitable for vegans and vegetarians. Its fatty portions are typically sourced from plant oils rather than animal tallow and the amino acid part comes from fermented plant sugars so no animal-derived material is required in its production.
Current safety data show no specific risks for women who are pregnant or breastfeeding when the ingredient is used in rinse-off or leave-on cosmetics at normal levels. This is not medical advice and anyone who is expecting or nursing should check with a healthcare professional before starting a new product to be sure it fits their personal needs.
The molecule does not cause photosensitivity so it will not make skin more prone to sunburn. It is also odorless and free of common essential oil allergens which helps reduce scent-related reactions.
Potential Side Effects/Adverse Reactions
Responses to topical Disteareth-5 Lauroyl Glutamate differ from person to person. The points below cover potential but uncommon issues. When used at the levels normally found in cosmetics most people have no trouble.
- Mild skin redness or stinging with very sensitive or compromised skin
- Contact dermatitis in individuals allergic to coconut or corn-derived ingredients
- Eye irritation if the product accidentally gets into the eyes before rinsing
- Temporary dryness if used in a formula that is left on too long or paired with other strong surfactants
If you notice any discomfort stop using the product and consult a healthcare professional if symptoms persist.
Comedogenic Rating
Rating: 1 out of 5. Disteareth-5 Lauroyl Glutamate is water friendly and forms a thin conditioning film that rinses away instead of building up. The hydrophilic glutamate and ethoxylated portions keep the fatty chains dispersed so they do not lodge in pores.
It is generally suitable for people who are prone to acne or breakouts.
This score applies to normal use levels under 5 percent. Very rich leave-on creams that pair it with heavy waxes could feel more occlusive for extremely oily skin.
Summary
Disteareth-5 Lauroyl Glutamate cleanses, softens and conditions by combining an oil loving fatty tail with a water loving amino acid head. The molecule lifts away dirt while leaving a silky finish that smooths hair cuticles and moisturizes skin.
It is not the most common surfactant on store shelves but brands focused on gentle or sulfate free formulas pick it for its mildness and versatility.
Safety reviews rate it low risk for irritation or allergy in both rinse off and leave on products. Issues are rare but it is wise to patch test any new product that contains it before full use.
