Disodium Sebacate/Palm Kernelate Triglyceride
INCI: DISODIUM SEBACATE/PALM KERNELATE TRIGLYCERIDE
A gentle, soap-like cleanser that effectively removes oil and makeup without stripping the skin, making it a good choice for sensitive or dry skin types.
In plain English
This ingredient is a mild cleansing agent made by combining sebacic acid (from castor oil) with fatty acids from palm kernel oil. It works like a very gentle soap, helping to lift away dirt, oil, and makeup from your skin without leaving it feeling tight or dry. Because it's less harsh than traditional soaps, it's often used in cleansers for sensitive or dry skin.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Disodium Sebacate/Palm Kernelate Triglyceride.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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
A semi-synthetic surfactant and emulsifier created by esterifying disodium sebacate with triglycerides from palm kernel oil. It acts as a mild cleansing agent that helps water mix with oil and dirt so they can be rinsed away.
How it works
In a cosmetic product, this ingredient reduces the surface tension between water and oil, allowing them to blend. When you wash your face, it surrounds oil and dirt particles, lifting them off your skin so they can be rinsed away with water. Its mild nature means it doesn't strip the skin's natural moisture barrier as aggressively as harsher surfactants.
Pros
Gentle on skin
This cleanser is much milder than traditional soap, so it won't leave your skin feeling tight or dry after washing. It's a good option if you have sensitive or easily irritated skin.
Effective oil removal
Despite its gentleness, it still does a solid job of breaking down and rinsing away excess oil and daily grime, making it suitable for normal to combination skin as well.
Cons and cautions
Sustainability concerns
Palm kernel oil is a key source, and unless certified sustainable, its production can contribute to deforestation. Look for products with RSPO-certified palm oil if this matters to you.
Not for heavy makeup
If you wear long-wear or waterproof makeup, you may need a separate makeup remover or oil cleanser first, as this ingredient alone may not fully dissolve those products.
Best for
- People with dry or sensitive skin who need a gentle cleanser
- Anyone looking for a mild, everyday face wash that won't over-strip
Use caution if
- Those who prefer exclusively plant-based or fully natural ingredients, as this is semi-synthetic
