What Dibutyl Adipate does

Softens and smooths the skin feel
Helps dissolve and spread UV filters
Gives formulas a lighter, silky feel

Dibutyl Adipate is made by reacting adipic acid with butanol, a process called esterification, where an acid and an alcohol join to form an ester. The result is a light oil from the ester family, a group of ingredients many formulators rely on for smooth, pleasant textures.

In sunscreens, formulators often use it to help dissolve and disperse UV filters, the ingredients that absorb or reflect sunlight. It can also help a formula feel smoother and less tacky on the skin. On skin it spreads easily and feels light rather than heavy.

Good for

Nothing in particular for most skin types.

Frequently asked questions

Is Dibutyl Adipate safe for skin?

Dibutyl Adipate is widely used in cosmetics and is generally well tolerated. Like most ingredients, it could cause irritation for someone with sensitive skin or an allergy to it. If a product irritates you, stop using it and check with a doctor or dermatologist.

Why is Dibutyl Adipate in sunscreen?

It helps UV filters blend evenly into the formula. Some sun filters do not mix well on their own, so a helper ingredient keeps the blend even and stable. It also contributes to a lighter feel on the skin.
