Disodium C12-14 Sec-Pareth-7 Sulfosuccinate
INCI: DISODIUM C12-14 SEC-PARETH-7 SULFOSUCCINATE
A gentle, sulfate-free surfactant that effectively cleanses without stripping the skin's natural moisture barrier.
In plain English
This ingredient is a mild soap-like compound that helps water mix with oil and dirt so they can be rinsed away. It's often used in 'gentle' or 'sulfate-free' cleansers because it cleans effectively but is less likely to cause dryness or irritation compared to traditional sulfates like sodium lauryl sulfate.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant made by modifying fatty acids from coconut or palm oil with a sulfosuccinate group, creating a large, gentle molecule that cleanses without penetrating deeply into the skin.
How it works
It reduces the surface tension of water, allowing it to mix with oils and dirt on the skin. The large molecular size makes it harder for the ingredient to penetrate the skin barrier, which reduces irritation potential while still providing effective cleansing and foam.
Pros
Very gentle on skin
Its large molecular structure means it stays on the surface and doesn't penetrate the skin barrier, making it ideal for sensitive or easily irritated skin.
Sulfate-free alternative
Provides effective cleansing and foam without the harshness of sodium lauryl sulfate or sodium laureth sulfate, reducing the risk of dryness and tightness.
Cons and cautions
Potential palm oil sourcing
Often derived from palm oil, which can be associated with deforestation and habitat loss unless certified sustainable.
Not completely natural
As a semi-synthetic ingredient, it may not appeal to those seeking 100% natural or organic formulations.
Best for
- People with dry or sensitive skin
- Those looking for sulfate-free cleansers
- Anyone wanting a gentle daily face wash
Use caution if
- Individuals with known allergies to coconut or palm derivatives (rare)
- Those seeking a completely natural ingredient list
