Disodium Sebacate
INCI: DISODIUM SEBACATE
Disodium Sebacate is a gentle cleansing agent that helps remove dirt and oil without stripping the skin, making it suitable for sensitive skin types.
In plain English
Disodium Sebacate is a salt derived from sebacic acid, which comes from castor oil. In skincare, it acts as a mild surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away. It's often used in cleansers and face washes because it cleans effectively without being harsh or drying. Think of it as a gentle soap alternative that leaves skin feeling clean but not tight or irritated.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Disodium Sebacate is the disodium salt of sebacic acid, a dicarboxylic acid naturally found in castor oil. It is produced synthetically for cosmetic use and functions primarily as a surfactant and cleansing agent.
How it works
In a cosmetic product, Disodium Sebacate reduces the surface tension between water and oil, allowing oils and dirt on the skin to be emulsified and washed away. Its mild nature means it does not disrupt the skin's natural moisture barrier as much as stronger surfactants like sodium lauryl sulfate.
Pros
Gentle on skin
Disodium Sebacate is a mild surfactant that cleans without stripping the skin's natural oils, making it ideal for sensitive or reactive skin types.
Low irritation risk
It has a low irritation profile compared to many common surfactants, reducing the chance of redness or stinging during use.
Cons and cautions
Limited cleansing power
It may not effectively remove heavy or waterproof makeup, requiring a separate makeup remover or double cleansing step.
Potential dryness in high concentrations
If used in high amounts without supporting moisturizing ingredients, it can still cause some dryness over time.
Best for
- People with sensitive or dry skin
- Those looking for a mild daily cleanser
- Individuals with conditions like eczema or rosacea who need gentle cleansing
Use caution if
- Those who prefer oil-based or balm cleansers for heavy makeup removal
