Ingredient review
Acetylated Hydrogenated Tallow Glyceride
INCI: Acetylated Hydrogenated Tallow Glyceride
A semi-synthetic emollient that softens skin but may clog pores for some people, especially those prone to breakouts.
In plain English
This ingredient is a modified fat made from beef tallow (animal fat) that has been hydrogenated (hardened) and acetylated (chemically altered) to improve its texture and stability. In skincare, it acts as an emollient, meaning it helps soften and smooth the skin by forming a protective layer that reduces water loss. It's often used in moisturizers and lip balms for a rich, non-greasy feel. However, because it is a heavy oil, it can be comedogenic (pore-clogging) for some skin types.
Quick decision guide
Useful, but context matters
Acetylated Hydrogenated Tallow Glyceride can be useful, but watch for possible clogging concerns.
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 Acetylated Hydrogenated Tallow Glyceride.
- 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
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic lipid derived from hydrogenated tallow (beef fat) that has been acetylated to change its melting point and feel on the skin. It is a waxy, solid material at room temperature that melts on contact with skin.
How it works
It sits on the skin's surface, filling in gaps between skin cells and creating a barrier that locks in moisture. This reduces transepidermal water loss (TEWL) and leaves skin feeling soft and smooth. It also helps other ingredients spread evenly.
Pros
Excellent emollient
Softens and smooths dry, rough skin effectively, making it a good choice for winter moisturizers and lip balms.
Improves product feel
Gives creams and balms a rich, luxurious texture without feeling overly greasy, enhancing the user experience.
Cons and cautions
Potential pore clogger
Rated as moderately comedogenic, meaning it can cause breakouts or clog pores in people with acne-prone or oily skin.
Animal-derived
Sourced from beef tallow, so it is not suitable for vegans or those who prefer plant-based ingredients.
Best for
- People with dry or very dry skin
- Those looking for a rich, protective moisturizer for cold weather
Use caution if
- People with oily or acne-prone skin
- Vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at typical concentrations. Low irritation risk, but moderate comedogenic risk means it may not suit all skin types.
Research notes
Limited direct clinical studies on this specific ingredient, but its safety profile is supported by its long history of use in cosmetics and similarity to other hydrogenated glycerides. The Cosmetic Ingredient Review (CIR) panel has reviewed related tallow derivatives and found them safe as used.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) as a skin-conditioning agent. No known restrictions at typical use levels.
- Common uses
- Moisturizers, Lip balms, Bar soaps, Hair conditioners
- Environmental note
- Derived from animal byproducts of the meat industry, which may be considered more sustainable than virgin oils by some, but raises ethical concerns for others.
Good to know
- Acetylation reduces the melting point of hydrogenated tallow, making it feel less waxy and more spreadable on skin.
- It is often used in combination with lighter oils to balance texture and reduce comedogenic potential.
