Ingredient review
Isopropyl Tallowate
INCI: Isopropyl Tallowate
Isopropyl Tallowate is a fatty emollient that softens skin but may clog pores for some people.
In plain English
Isopropyl Tallowate is an ingredient made from animal fat (tallow) that is chemically modified to become a smooth, spreadable oil. It helps moisturizers and creams feel silky and non-greasy on the skin. Because it is derived from animal sources, it may not be suitable for vegans or those avoiding animal products. It can also be comedogenic, meaning it might block pores and cause breakouts in acne-prone skin.

Quick decision guide
Useful, but context matters
Isopropyl Tallowate 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 Isopropyl 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
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
Isopropyl Tallowate is an ester formed by reacting isopropyl alcohol with fatty acids from tallow (rendered beef or mutton fat). It appears as a clear to yellowish liquid and functions as an emollient and skin conditioning agent in cosmetics.
How it works
It works by forming a thin, protective film on the skin's surface, which reduces water loss and leaves skin feeling soft and smooth. Its oily nature helps other ingredients spread evenly and enhances the texture of creams and lotions.
Pros
Silky texture
Creates a smooth, non-greasy feel on skin, making products more pleasant to apply.
Good moisturizer
Helps lock in moisture by forming a protective layer, beneficial for dry skin types.
Cons and cautions
Pore-clogging potential
Rated moderate on the comedogenic scale, it may cause blackheads or breakouts in acne-prone skin.
Animal-derived
Sourced from animal fat, so it is not suitable for vegans or those preferring plant-based ingredients.
Best for
- People with dry or normal skin looking for a rich emollient
- Those who tolerate fatty ingredients well
Use caution if
- Individuals with oily or acne-prone skin
- Vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
Isopropyl Tallowate is generally considered safe for topical use in cosmetics. It has low irritation potential but moderate comedogenic risk, meaning it can clog pores for some individuals. It is not associated with serious health concerns when used as directed.
Research notes
Limited peer-reviewed studies specifically on Isopropyl Tallowate; its safety profile is inferred from similar fatty esters. Comedogenicity is based on historical rabbit ear assays and anecdotal reports. Regulatory bodies consider it safe at typical cosmetic concentrations.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific restrictions at typical concentrations.
- Common uses
- Moisturizers, Creams, Lotions, Lip products, Makeup
- Environmental note
- Derived from animal agriculture byproducts, which may have a higher environmental footprint compared to plant-based alternatives.
Good to know
- Isopropyl Tallowate is sometimes used as a substitute for mineral oil in natural formulations.
- It is chemically similar to other isopropyl esters like Isopropyl Myristate, which also have moderate comedogenic ratings.
