What Is C10-14 Alkyl Benzenesulfonic Acid?
C10-14 Alkyl Benzenesulfonic Acid is a surfactant made by attaching a chain of ten to fourteen carbon atoms to a benzenesulfonic acid core. The carbon chain is sourced from petroleum fractions or plant oils, then reacted with benzene followed by sulfonation to add the sulfonic acid group. This process creates a molecule that is both oil loving and water loving, letting it break up grease while rinsing away with water.
The ingredient entered household cleaners in the 1960s as a more biodegradable option than older surfactants. Its strong cleaning power soon made it popular in personal care where a good lather and thorough cleanse are prized. Today you will find it in face washes, body washes, hand soaps, clarifying shampoos, exfoliating scrubs and some makeup brush cleansers.
C10-14 Alkyl Benzenesulfonic Acid’s Cosmetic Benefits/Uses
This ingredient earns its place in formulas thanks to the roles below
- Cleansing: Lifts oil, dirt and leftover makeup from skin or hair so they can be rinsed away quickly, leaving a fresh feel without heavy residue.
- Foaming: Creates a rich stable lather that spreads the product easily over the surface, helping users gauge coverage and giving a satisfying sensory experience.
Who Can Use C10-14 Alkyl Benzenesulfonic Acid
Products containing this surfactant work best for normal, combination and oily skin because they remove excess sebum with ease. Those with very dry or easily irritated skin might find it too stripping since it can take away natural oils along with dirt. Sensitive skin types should look for formulas where the ingredient is paired with milder co-surfactants or soothing agents.
The molecule is made from petroleum fractions or plant oils and involves no animal-derived substances or animal testing requirements, so it is generally considered suitable for vegans and vegetarians.
No data suggest special risks for pregnant or breastfeeding women when the ingredient is used at the low levels found in rinse-off products. This is not medical advice and anyone who is pregnant or nursing should check with a healthcare professional before adding new skincare to their routine.
C10-14 Alkyl Benzenesulfonic Acid is not known to cause photosensitivity and does not make skin more prone to sunburn. Standard sun protection habits are still recommended for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical C10-14 Alkyl Benzenesulfonic Acid differ from person to person. The points below outline possible effects though most people will not notice any problems when the ingredient is used correctly in a finished product.
- Dryness or tight feeling after rinsing
- Redness or stinging on sensitive or compromised skin
- Contact irritation or rash in rare cases of intolerance
- Eye irritation if the product gets into the eyes
If any discomfort or visible reaction occurs stop using the product and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 0/5
C10-14 Alkyl Benzenesulfonic Acid is a water-soluble surfactant that rinses off almost completely, leaving minimal residue on the skin or inside pores. Because it does not leave an oily film and has no long-chain fatty acids known to clog pores, it earns a solid zero on the comedogenic scale.
In practical terms this makes the ingredient generally safe for people who are prone to acne or breakouts. Its quick rinse-off profile further reduces any risk of pore blockage.
As with any cleansing agent, prolonged contact time or very high concentrations can be drying, which might indirectly aggravate acne in sensitive individuals, but under typical use conditions it remains non-comedogenic.
Summary
C10-14 Alkyl Benzenesulfonic Acid is a hard-working surfactant valued for two main jobs: breaking up oil and dirt for thorough cleansing and whipping up a rich foam that spreads product evenly. Its dual oil-loving and water-loving structure lets it grab grime then wash cleanly away with water, leaving skin or hair feeling fresh.
While not as famous as sulfate surfactants, it appears in plenty of facial cleansers, body washes and clarifying shampoos where a strong yet easily rinsed cleanse is desired. Formulators like it for its consistent performance and biodegradability compared with older surfactants.
Safety studies and decades of use show it is generally low risk when used at the modest levels found in rinse-off products, though it can be drying on very sensitive skin. As with any new skincare item, a quick patch test is still a smart move to make sure your skin agrees with the formula.
