Ingredient review
Dihydrogenated Tallow Phthalic Acid Amide
INCI: DIHYDROGENATED TALLOW PHTHALIC ACID AMIDE
A synthetic film-forming ingredient that helps products spread smoothly and hold their shape, but its safety data is limited and it may not suit sensitive or acne-prone skin.
In plain English
This is a man-made ingredient that helps cosmetic products form a thin, flexible film on your skin or hair. It's often used in styling products to help hold a hairstyle or in creams to improve their texture. Because it's derived from tallow (a type of animal fat) and phthalic acid, it's not plant-based. There isn't a lot of independent research on its long-term safety, so it's best used in moderation, especially if you have sensitive or breakout-prone skin.

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 Phthalic Acid Amide.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic amide compound created by reacting hydrogenated tallow fatty acids with phthalic acid. It functions as a film former and viscosity modifier in cosmetic formulations.
How it works
When applied, it forms a thin, flexible film on the skin or hair surface. This film helps other ingredients stay in place, improves the texture of the product, and can provide a light hold for hairstyles. It also helps control the thickness of the product so it spreads easily.
Pros
Improves product feel
Helps creams and lotions spread smoothly without feeling greasy, making the application experience more pleasant.
Light hold for hair
Provides a flexible, non-stiff hold in styling products, allowing hair to move naturally while maintaining shape.
Cons and cautions
Limited safety research
There is little independent or long-term safety data available, so its full safety profile is not well understood.
May clog pores
Some users with acne-prone skin may find it comedogenic, so it's wise to patch test before regular use.
Best for
- Those looking for a lightweight film former in styling products
- People who want improved texture in creams and lotions
Use caution if
- Individuals with very sensitive or acne-prone skin should patch test first
Usage tips
Safety summary
Generally considered safe at low concentrations in cosmetics, but long-term safety data is limited. Some individuals may experience irritation or clogged pores. Patch testing is recommended.
