What Is Disodium C12-14 Sec-Alketh-12 Sulfosuccinate?
Disodium C12-14 Sec-Alketh-12 Sulfosuccinate is a synthetically produced surfactant made from a blend of secondary fatty alcohols that come from mid-length coconut or palm-derived chains, each linked to roughly 12 units of ethylene oxide, then partially esterified with sulfosuccinic acid and neutralised with sodium ions. This process gives the molecule a water-loving head and an oil-loving tail, a classic setup for lifting dirt from skin or hair.
The compound first appeared in personal care labs in the late 1970s when formulators looked for milder, more versatile alternatives to sulfate surfactants. By tweaking chain length and ethoxylation level, chemists created a cleansing agent that foams well but feels gentler on skin. Over time it moved from salon shampoos into everyday body washes, facial cleansers, bubble baths and even baby care products.
Industrial production begins with fatty alcohols that are reacted with ethylene oxide under controlled heat and pressure to add the desired number of ethoxy groups. The resulting alcohol ethoxylates are treated with sulfosuccinic anhydride to form half-esters, then neutralised with sodium hydroxide to yield the final disodium salt. The finished ingredient is usually supplied as a clear to pale yellow liquid that dissolves easily in water.
You will most often spot Disodium C12-14 Sec-Alketh-12 Sulfosuccinate in shampoos, shower gels, facial cleansers, bubble baths, micellar waters and kids’ bath products where a rich yet mild foam is desired. It is less common in leave-on creams or serums but may appear in exfoliating masks or makeup removers that need rinse-off cleansing power.
Disodium C12-14 Sec-Alketh-12 Sulfosuccinate’s Cosmetic Benefits/Uses
In formulas this ingredient pulls triple duty, making products easier to use and more enjoyable.
- Cleansing: Its surfactant nature loosens and lifts away oil, sweat and makeup so they rinse off with water, leaving skin and hair feeling fresh without an overly stripped sensation
- Foam boosting: It enhances lather volume and stability which gives users the sensory cue that a product is working and helps spread the cleanser evenly over the surface
- Hydrotrope: Acts as a solubiliser that keeps oils, fragrances and other ingredients dissolved in water-based formulas, preventing separation and ensuring a clear, uniform product
Who Can Use Disodium C12-14 Sec-Alketh-12 Sulfosuccinate
This surfactant suits most skin types including oily, combination and normal because it removes grime without a harsh stripping feel. Dry or very sensitive skin can usually tolerate it as well since it is milder than traditional sulfates, though some individuals may still prefer shorter contact times or lower concentrations.
The ingredient is synthetic and contains no animal-derived matter so it is considered suitable for vegetarians and vegans.
No data suggest that topical use poses specific risks to pregnant or breastfeeding women when the product is formulated and used as directed. This is general information, not medical advice, so anyone who is expecting or nursing should ask a healthcare professional before starting a new skincare product.
Disodium C12-14 Sec-Alketh-12 Sulfosuccinate does not increase photosensitivity and there are no known interactions with sun exposure. It is also fragrance free by itself which can be helpful for people avoiding added scent.
Potential Side Effects/Adverse Reactions
Reactions to any cosmetic ingredient vary from person to person. The points below outline potential side effects only; most users will not experience these issues when the product is made and used correctly.
- Mild eye irritation if the cleanser accidentally gets into the eyes
- Temporary skin stinging or tightness, especially on very dry or compromised skin
- Contact dermatitis in rare cases of individual sensitivity
- Scalp dryness or flaking when used in high-foaming shampoos on already dry scalps
If any irritation or discomfort occurs stop use and consult a medical professional if symptoms persist.
Comedogenic Rating
Rating: 1/5
Although the molecule carries mid-length fatty chains, it is highly water soluble and designed for rinse-off use, so it does not linger on skin long enough to block pores. Its primary job is to suspend and wash away oils rather than deposit them, which keeps the clogging potential very low.
Suitable for acne-prone or breakout-prone skin in most cases
Because it is most often used in cleansers the formula itself is washed away within seconds, further limiting any chance of residue that could build up over time.
Summary
Disodium C12-14 Sec-Alketh-12 Sulfosuccinate works as a cleanser, foam booster and hydrotrope. Its dual water-loving and oil-loving structure lifts dirt and makeup then traps them in a fine, creamy lather that rinses clean. At the same time it helps keep fragrance oils and other tricky ingredients dissolved so the final product stays clear and even.
While not as famous as classic sulfates or newer ultra-gentle glucosides, it has carved out a solid niche in everyday shampoos, body washes and bubble baths thanks to its balance of mildness and rich foam.
Safety reviews rate it as low irritation when used as directed, with rare reports of sensitivity. As with any new skincare product, do a quick patch test first to check personal tolerance, especially if your skin is easily upset.
