The main component of C13 alcohol polyether E-1340 is isotridecanol polyoxyethylene (13) ether, with an effective active content of ≥99%.

Detailed Description

C13 alcohol polyether E-1340 is a high-performance non-ionic surfactant, whose chemical essence is an ether compound prepared by the addition polymerization of isotridecanol (C13 branched-chain fatty alcohol) with about 13 ethylene oxide (EO) molecules.

According to the product specifications of Guoli Chemical, the effective active ingredient content of this product is extremely high (≥99%), making it a high-purity refined product. Its general chemical formula can be expressed as C13H27(OCH2CH2)nOH, where n ≈ 13~14. The free alcohol content in the finished product is strictly controlled (≤1%), ensuring excellent surface activity and chemical stability.

Technical Parameters

The following are the main components and physicochemical parameters of C13 alcohol polyether E-1340:
