What Trimethylpentanediyl Dibenzoate does

  • Softens and smooths the skin
  • Helps pigments disperse evenly
  • Gives a light, non-greasy feel
  • Keeps film formers flexible

Trimethylpentanediyl Dibenzoate is made by attaching two benzoic acid molecules to a branched diol called 2,2,4-trimethyl-1,3-pentanediol. Its branched structure keeps it liquid and easy to blend, so it mixes well with many cosmetic oils and esters.

Formulators use it as an emollient, which means it softens skin and helps it feel smooth. It also helps pigments disperse evenly in makeup and can keep film formers flexible so they do not crack. The finish is soft and light rather than greasy, so it shows up in lotions, creams and color cosmetics.

Good for

Suits people who want a silky, non-greasy feel in lotions, creams and makeup, including those who find heavy oils too rich.

Frequently asked questions

Is Trimethylpentanediyl Dibenzoate the same as a silicone?

No. It is an organic ester, not a silicone. Silicones are built on silicon-oxygen chains, while this ingredient comes from benzoic acid and a branched diol. Both can give a smooth, slip-like feel, so they are often compared in formulas.

Does it make skin oily?

It is an oil-type ingredient, but it is usually light and spreads without leaving a heavy layer. It typically leaves a soft feel rather than a greasy shine. How much shine you notice also depends on the other ingredients in the product.
