What Is Disodium Deceth-5 Sulfosuccinate?
Disodium Deceth-5 Sulfosuccinate is a synthetic surfactant created from decyl alcohol that has been reacted with ethylene oxide to form Deceth-5, then combined with maleic anhydride, sulfonated and finally neutralized with sodium hydroxide to yield its disodium salt. Chemically it belongs to the sulfosuccinate family, molecules known for their ability to lower surface tension and mix oil with water. Sulfosuccinates first entered personal care labs in the 1950s as a gentler alternative to harsher soaps, quickly finding favor in baby shampoos and sensitive-skin washes. Today the ingredient is produced in large-scale reactors where temperature and pH are tightly controlled to ensure consistent mildness and purity.
You will most often spot Disodium Deceth-5 Sulfosuccinate in foaming facial cleansers, micellar waters, sulfate-free shampoos, body washes, bubble baths, makeup removing wipes, peel-off masks and even pre-shave treatments that need quick, gentle rinsing. Formulators like it because it plays well with other surfactants and remains effective across a wide pH range.
Disodium Deceth-5 Sulfosuccinate’s Cosmetic Benefits/Uses
This multitasking surfactant offers several perks when blended into a formula
- Cleansing – lifts away dirt, excess oil and makeup by surrounding grime with micelles that can be rinsed off with water leaving skin or hair feeling fresh but not stripped
- Foam Boosting – enhances lather volume and stability so products feel rich and cushiony during use improving the overall sensory experience
- Hydrotrope – helps keep other ingredients dissolved in water based systems preventing cloudiness or separation which allows brands to create clear elegant gels and liquids
Who Can Use Disodium Deceth-5 Sulfosuccinate
Because it is a mild, sulfate-free surfactant, Disodium Deceth-5 Sulfosuccinate generally works well for normal, oily, combination and sensitive skin types. Dry or eczema-prone skin can usually tolerate it too, although formulas that pair the ingredient with ample moisturizers tend to feel more comfortable for those groups. People with extremely compromised or cracked skin may still notice slight stinging from any cleanser, so caution is advised.
The ingredient is fully synthetic and does not rely on animal-derived raw materials, making it suitable for vegans and vegetarians.
Current safety data show no reproductive toxicity, so products that contain Disodium Deceth-5 Sulfosuccinate are considered safe for use during pregnancy and breastfeeding. This is not medical advice; anyone who is pregnant or nursing should check with a doctor before starting a new personal care product just to be sure.
Disodium Deceth-5 Sulfosuccinate does not increase photosensitivity, so there is no special need to avoid sunlight beyond regular sun protection habits.
Potential Side Effects/Adverse Reactions
Reactions to topical Disodium Deceth-5 Sulfosuccinate vary from person to person. The following list covers potential side effects, most of which are uncommon when the ingredient is used at appropriate levels in well-formulated products.
- Mild eye irritation
- Transient skin dryness or tightness
- Contact dermatitis in individuals allergic to sulfosuccinates
- Scalp itching or flaking when used in shampoos by very sensitive users
If any discomfort or irritation occurs while using a product that contains this ingredient, discontinue use and consult a healthcare professional.
Comedogenic Rating
Rating: 0 / 5. Disodium Deceth-5 Sulfosuccinate dissolves completely in water, rinses off easily and does not leave an oily film on the skin so it has virtually no ability to clog pores. It is therefore considered suitable for people who are prone to acne or breakouts. If a product that contains this surfactant still triggers congestion the culprit is almost always another, more occlusive ingredient rather than the sulfosuccinate itself.
Summary
Disodium Deceth-5 Sulfosuccinate is prized for three main jobs: it cleans by surrounding dirt and oil so they rinse away, it boosts foam to give washes a rich lather, and it acts as a hydrotrope that keeps formulas clear and stable. This combination makes it a handy choice for sulfate free shampoos, gentle face washes and micellar waters. While it is not as famous as household names like Sodium Lauryl Sulfate, it enjoys steady use in products aimed at sensitive skin because it offers good performance with less sting.
Current research shows the ingredient is low risk with very limited irritation potential when used at typical cosmetic levels. Still, skin is personal so it is wise to patch test any new product that lists Disodium Deceth-5 Sulfosuccinate just to be sure it suits you.
