Ingredient review
Sodium Hydrogenated Tallowate
INCI: Sodium Hydrogenated Tallowate
An effective but potentially drying cleanser derived from animal fat, best for oily skin types.
In plain English
Sodium Hydrogenated Tallowate is a soap ingredient made from beef tallow that has been hydrogenated to make it harder and more stable. It works by helping water mix with oil and dirt so they can be rinsed away. While it cleans well, it can be drying for some skin types because it strips natural oils.

Quick decision guide
Useful, but context matters
Sodium Hydrogenated Tallowate 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 Tallowate.
- 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 tallow fatty acids, used as a surfactant in soap-making. Tallow is rendered animal fat, and hydrogenation makes it more solid and less prone to rancidity.
How it works
It acts as a surfactant, reducing the surface tension between water and oils, allowing dirt and sebum to be emulsified and washed away. In bar soaps, it contributes to a hard, long-lasting bar with a creamy lather.
Pros
Strong cleanser
Effectively removes excess oil, dirt, and impurities, making it ideal for oily skin types.
Bar soap stability
Contributes to a hard, long-lasting soap bar that doesn't dissolve quickly in water.
Cons and cautions
Can be drying
May strip the skin of natural oils, leading to tightness or irritation, especially for dry or sensitive skin.
Animal-derived
Sourced from beef tallow, so it is not suitable for vegans or those avoiding animal products.
Best for
- People with oily or combination skin who need thorough cleansing
- Those who prefer traditional bar soaps over liquid cleansers
Use caution if
- Individuals with dry, sensitive, or eczema-prone skin due to potential drying effects
Usage tips
Safety summary
Generally recognized as safe for topical use in rinse-off products. However, it can be drying and may cause irritation for sensitive skin due to its strong cleansing action.
Research notes
Limited direct studies on Sodium Hydrogenated Tallowate, but tallowate soaps have a long history of safe use. Their cleansing efficacy and potential for skin barrier disruption are well-documented in surfactant research.
Common label clues
- Typical concentration
- Typically 5–30% in soap formulations
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database as a surfactant and cleansing agent.
- Common uses
- Bar soaps, Facial cleansers, Body washes
- Environmental note
- Tallow is a byproduct of the meat industry, so its use can be seen as reducing waste, but it is not plant-based or vegan-friendly.
Good to know
- Hydrogenation makes the tallow more stable and less likely to go rancid in soap.
- Commonly found in traditional bar soaps like many drugstore brands.
