What Is Disodium C12-14 Sec-Alketh-5 Sulfosuccinate?
Disodium C12-14 Sec-Alketh-5 Sulfosuccinate is a synthetic surfactant created from secondary fatty alcohols that contain 12 to 14 carbon atoms. These alcohols are first reacted with ethylene oxide to attach an average of five ethoxy units, then partially esterified with sulfosuccinic acid and finally neutralized with sodium hydroxide to form the disodium salt. The process yields a water-soluble ingredient valued for its gentle yet effective cleansing profile.
The material appeared in personal care labs in the late 1960s as chemists searched for surfactants that produced rich foam without the irritation sometimes linked to traditional sulfates. Its balance of mildness and performance quickly made it a staple in rinse-off products and it has remained popular as consumer demand for gentle formulas has grown.
You will most often spot Disodium C12-14 Sec-Alketh-5 Sulfosuccinate in shampoos, body washes, bubble baths, facial cleansers, makeup removers, exfoliating scrubs and even some baby care items. Formulators choose it when they need dependable foam, quick rinse-off and compatibility with a wide range of other ingredients.
Disodium C12-14 Sec-Alketh-5 Sulfosuccinate’s Cosmetic Benefits/Uses
This multifunctional surfactant strengthens a formula in several ways
- Cleansing: Lifts away oil, dirt and product buildup so skin and hair feel fresh without a tight or squeaky finish

Who Can Use Disodium C12-14 Sec-Alketh-5 Sulfosuccinate
This ingredient is generally well tolerated by normal, oily, combination and sensitive skin because it cleanses gently and rinses away without leaving a residue. Those with very dry or compromised skin might prefer products that pair it with extra emollients since any surfactant can accentuate dryness if overused.
Because it is produced from petrochemical or plant based raw materials and involves no animal derived substances or testing mandates, it is suitable for vegans and vegetarians.
Available safety data show no specific concerns for topical use during pregnancy or while breastfeeding, especially in rinse off formats like shampoos and cleansers. This is not medical advice and anyone who is pregnant or nursing should confirm product choices with a qualified doctor to be safe.
The ingredient does not make skin more sensitive to sunlight so it does not require special photoprotection beyond normal sunscreen habits.

Comedogenic Rating
Rating: 0 / 5
Disodium C12-14 Sec-Alketh-5 Sulfosuccinate is a water-soluble surfactant that stays on the skin only briefly before being rinsed away. It does not leave an oily film or penetrate deep into pores which means it has virtually no potential to clog them. Because of this it is considered non-comedogenic and is generally suitable for people who are prone to acne or breakouts.
Its rinse-off usage further lowers any risk since contact time is short. As with most cleansing agents any drying effect that triggers excess sebum could indirectly influence breakouts but this is easily balanced by using an appropriate moisturizer.
Summary
Disodium C12-14 Sec-Alketh-5 Sulfosuccinate is best known for three jobs: it cleanses by surrounding and lifting away oil and debris it boosts a rich creamy foam that makes washing feel pleasant and it acts as a hydrotrope keeping hard-to-dissolve ingredients evenly dispersed so formulas stay clear and stable.
Thanks to its mildness and reliable performance the ingredient appears in a wide range of shampoos body washes and facial cleansers and is especially popular in products marketed as sulfate-free or gentle.
Current research and decades of consumer use show it is safe for topical application with a very low chance of irritation or sensitization when used as directed. Still skin can be unpredictable so it is wise to patch test any new product containing this surfactant before full-face or full-body use.
