Dodecylbenzenesulfonic Acid, Isopropylamine Salt (CAS 26264-05-1) is the isopropylamine (1:1) salt of dodecylbenzene sulfonic acid, an anionic surfactant of the linear alkylbenzene sulfonate family. Amine salts of LAS are used as surfactants and emulsifiers, including in solvent- and oil-compatible systems.

Frequently Asked Questions

What is isopropylamine dodecylbenzenesulfonate?

Isopropylamine dodecylbenzenesulfonate (CAS 26264-05-1) is the isopropylamine (1:1) salt of dodecylbenzene sulfonic acid — an anionic surfactant of the linear alkylbenzene sulfonate (LAS) family. The amine salt form is used as a surfactant and emulsifier, including in solvent- and oil-compatible systems.

What is dodecylbenzenesulfonic acid (isopropylamine salt) used for?

It is used as an anionic surfactant, an emulsifier in industrial and agrochemical formulations, and a wetting agent that reduces surface tension in formulated systems. The amine-salt form offers solvent and oil compatibility versus the free acid. Application suitability should be confirmed against the CoA and SDS.

What is another name for dodecylbenzenesulfonic acid?

The parent acid is commonly called DBSA or LAS acid; this product is its isopropylamine (1:1) salt, sometimes written as DBSA isopropylamine salt or IPA-DBSA. Reference CAS 26264-05-1 to distinguish the salt from the free acid (CAS 27176-87-0). Molecular formula is C21H39NO3S.

How does the isopropylamine salt differ from the free acid?

The isopropylamine salt is the neutralized (amine) form of dodecylbenzene sulfonic acid, giving a near-neutral surfactant with improved solubility in solvent- and oil-based systems compared with the strongly acidic free acid. Choose the salt where acidity or oil compatibility is a constraint. Confirm specifications on the CoA.
