Ingredient review
Dihydrogenated Tallow Phthalate
INCI: Dihydrogenated Tallow Phthalate
A synthetic emollient that helps products feel smooth and stay put, but may be too heavy for oily or acne-prone skin.
In plain English
Dihydrogenated Tallow Phthalate is a man-made ingredient that comes from animal fats (tallow) and phthalic acid. In skincare and makeup, it acts like a soft wax: it helps products spread smoothly, feel silky, and resist water. You'll often find it in lipsticks and long-wear makeup. However, because it can be heavy and potentially clog pores, it's not ideal for oily or acne-prone skin. It's considered safe in small amounts, but some people prefer to avoid phthalate-related ingredients due to general concerns about phthalates.

Quick decision guide
Useful, but context matters
Dihydrogenated Tallow Phthalate 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 Dihydrogenated Tallow Phthalate.
- 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 synthetic ester made by reacting hydrogenated tallow (a processed animal fat) with phthalic acid. It is a waxy solid at room temperature and is used as an emollient and film former.
How it works
It forms a thin, flexible film on the skin or lips, helping to lock in moisture and improve water resistance. Its emollient properties soften the skin and give a smooth, non-greasy feel.
Pros
Improves wear time
Creates a water-resistant film that helps makeup and lip products last longer without smudging.
Silky texture
Gives a smooth, non-greasy feel that makes products glide on easily and feel comfortable.
Cons and cautions
May clog pores
Its heavy, waxy nature can be comedogenic for some, potentially leading to breakouts in acne-prone skin.
Not vegan-friendly
Derived from animal fat (tallow), so it is not suitable for vegans or those avoiding animal products.
Best for
- Those looking for long-wear lip products
- People with dry or normal skin who want a smooth, protective layer
Use caution if
- Those with oily or acne-prone skin
- Vegans and those avoiding animal-derived ingredients
Usage tips
Safety summary
Generally considered safe for use in cosmetics at typical concentrations. Low irritation risk, but moderate comedogenic potential. Those with acne-prone skin should use with caution. The phthalate ester structure is different from controversial phthalates like DEHP, but some consumers prefer to avoid any phthalate-related ingredients.
Research notes
Limited direct studies on this specific ingredient, but related phthalate esters have been reviewed by the Cosmetic Ingredient Review (CIR) and found safe. The main concerns are comedogenicity and animal origin, not toxicity.
Common label clues
- Typical concentration
- Typically 1–10% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed related phthalate esters and found them safe at current usage levels.
- Common uses
- Lipsticks, Lip balms, Water-resistant creams, Makeup removers
- Environmental note
- Derived from animal fat, which may have a higher environmental footprint than plant-based alternatives. Not biodegradable in all conditions.
Good to know
- Despite its name, this ingredient is not a phthalate in the controversial sense—it is a phthalate ester that is considered safe by regulators at typical use levels.
- It is often used in combination with other emollients to balance texture.
