What Is Disodium Lauriminobishydroxypropylsulfonate?
Disodium Lauriminobishydroxypropylsulfonate, sometimes shortened to DLHS, is a mild surfactant made by linking a plant derived fatty chain, usually from coconut or palm kernel oil, with hydroxypropyl and sulfonate groups. These extra water-loving parts let the molecule mix oil and water, a key trait for cleansers. The ingredient first appeared in personal care labs in the late 1990s when formulators were searching for gentler foaming agents that would not strip skin. Today it is produced through a two-step reaction. First the natural fatty amine is treated with propylene oxide to add the hydroxypropyl groups. That intermediate is then reacted with sodium bisulfite to attach the sulfonate sites and finally neutralized with sodium hydroxide, yielding a readily water-soluble powder or paste.
You will most often spot this surfactant in rinse-off products that need a soft, cushiony lather such as shampoos, body washes and facial cleansers. It can also appear in shaving creams, bubble baths and micellar waters where extra foam is desirable but skin feel must stay silky.
Disodium Lauriminobishydroxypropylsulfonate’s Cosmetic Benefits/Uses
Formulators choose this ingredient for the way it improves both performance and user experience in wash-off products.
- Cleansing – lifts away dirt, oil and daily grime without leaving skin tight or hair squeaky
- Foaming – creates a rich lather that spreads easily, helping consumers feel the product is working
- Foam Boosting – partners with other surfactants to increase bubble volume and stability so the foam lasts throughout use
Who Can Use Disodium Lauriminobishydroxypropylsulfonate
This gentle cleanser is considered suitable for nearly all skin and hair types. It works well for normal, dry, oily and even sensitive skin because its mild formula removes buildup while helping the skin barrier hold on to moisture. Those with very reactive or allergy-prone skin should still read full ingredient lists since irritation can arise from other components in the final product rather than from DLHS itself.
DLHS is typically sourced from coconut or palm kernel oil so it contains no animal-derived materials and is therefore appropriate for vegetarians and vegans. As always, check the brand’s overall cruelty-free stance if that is important to you.
Current safety assessments show no specific concerns for pregnant or breastfeeding women when DLHS is used in rinse-off products. Because every pregnancy is unique, this is not medical advice and expectant or nursing mothers should have their healthcare provider review any personal care routine before use.
The ingredient is not known to trigger photosensitivity, so it will not make skin more prone to sunburn. It is also readily biodegradable which can be a plus for consumers who prioritize eco-friendliness.
Potential Side Effects/Adverse Reactions
Individual responses to topical ingredients can differ. The effects listed below are possible yet uncommon when DLHS is formulated and used as intended.
- Transient eye stinging if the cleanser is accidentally rubbed into the eyes
- Mild skin redness or itching in people with a true sulfonate sensitivity
- Dryness if used in very high concentrations or alongside multiple other cleansers in the same routine
- Rare allergic contact dermatitis presenting as a rash or swelling
If any of these reactions occur stop using the product and consult a medical professional for personalized guidance.
Comedogenic Rating
Rating: 0/5. Disodium Lauriminobishydroxypropylsulfonate is a highly water-soluble surfactant that rinses off completely and does not leave an oily film behind, so it does not block pores. Its molecular structure is designed to interact with water rather than stay on the skin, which further reduces any clogging potential. Because of this it is generally suitable for people who are prone to acne or breakouts. Since it is used almost exclusively in rinse-off formulas, contact time on the skin is short, keeping the comedogenic risk minimal.
Summary
Disodium Lauriminobishydroxypropylsulfonate works as a gentle surfactant that excels at cleansing, foaming and foam boosting. The hydroxypropyl and sulfonate groups pull water while the fatty tail grabs oils, allowing it to lift grime then rinse away easily. In formulas it teams up with other mild surfactants to create a creamy stable lather that feels plush rather than stripping.
The ingredient is fairly common in modern shampoos, face washes and body cleansers, though it has not reached the name recognition of classic sulfates or newer sulfate-free stars. Formulators appreciate its mildness and ability to enhance foam without harshness, which is why its use has been steadily climbing.
Safety reviews rate it as low risk when used in typical rinse-off concentrations, with irritation or allergen potential considered rare. As with any new skincare product it is wise to perform a quick patch test before full use just to be on the safe side.
