Ingredient review
Sodium Hydrogenated Palmate
INCI: Sodium Hydrogenated Palmate
An effective but potentially drying soap ingredient that works well for oily skin but may strip moisture from dry or sensitive skin.
In plain English
Sodium Hydrogenated Palmate is a soap-making ingredient made from palm oil that has been hydrogenated (hardened) to create a solid bar. It acts as a surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away. Because it is a true soap, it can be quite alkaline and may leave skin feeling tight or dry, especially for those with sensitive or dry skin.

Quick decision guide
Useful, but context matters
Sodium Hydrogenated Palmate can be useful, but watch for some irritation potential.
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 Sodium Hydrogenated Palmate.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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 sodium salt of hydrogenated palm oil fatty acids, used as a primary cleansing agent in solid soap formulations.
How it works
When mixed with water, it forms micelles that trap oil, dirt, and makeup, allowing them to be washed away. Its alkaline pH (typically 9–10) helps break down oils but can also disrupt the skin's natural acid mantle.
Pros
Effective cleanser
Removes excess oil, sweat, and impurities thoroughly, leaving skin feeling clean.
Good lather in bars
Creates a dense, creamy foam that many people find satisfying in a bar soap.
Cons and cautions
Can be drying
Its high pH can strip the skin's natural oils, leading to tightness and dryness after washing.
Potential irritant
May cause stinging or redness on sensitive or compromised skin due to its alkalinity.
Best for
- People with oily or combination skin who prefer a thorough cleanse
- Those who enjoy traditional bar soap textures
Use caution if
- Individuals with dry, sensitive, or eczema-prone skin
- Anyone looking for a pH-balanced, non-stripping cleanser
Usage tips
Safety summary
Generally recognized as safe for topical use in rinse-off products. However, its high pH can disrupt the skin barrier with frequent use, especially on sensitive skin. Not associated with toxicity or systemic risks.
Research notes
Limited direct studies on Sodium Hydrogenated Palmate specifically, but research on soap-based cleansers confirms they are effective but more alkaline and potentially more irritating than synthetic detergents. The Cosmetic Ingredient Review (CIR) has evaluated similar fatty acid salts and found them safe in rinse-off formulations.
Common label clues
- Typical concentration
- 5–20% in bar soaps; lower in liquid cleansers
- Regulatory status
- Approved for use in cosmetics and soaps by FDA and EU CosIng; no specific restrictions beyond general soap safety.
- Common uses
- Bar soaps, Facial cleansers, Body washes
- Environmental note
- Palm oil production can contribute to deforestation; choose products with RSPO-certified sustainable palm oil when possible.
Good to know
- Sodium Hydrogenated Palmate is often combined with other surfactants to reduce its harshness.
- Look for 'palm oil sustainable' certifications if you are concerned about environmental impact.
