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.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

moderate

May be fine for many users but deserves caution if you are breakout-prone.

Evidence level

emerging

The 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

Always patch test a new product containing this ingredient on a small area of skin before full application.
Use in moderation—products with high concentrations may feel heavy or cause buildup on hair.

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.

Research notes

There is minimal peer-reviewed research on this specific ingredient. Most safety assessments rely on general knowledge of similar amide compounds and industry self-regulation.

Common label clues

Typically used at 0.5–5% in formulations
Regulatory status
Approved for use in cosmetics in the US and EU, but subject to concentration limits and labeling requirements. Always check local regulations.
Common uses
Hair styling products, Creams, Lotions
Environmental note
Derived from animal fat (tallow) and synthetic phthalic acid; not biodegradable and may have environmental persistence concerns.

Good to know

  • This ingredient is synthetic and not suitable for vegan or plant-based routines.
  • It is often used in combination with other film formers to achieve desired texture and hold.
