Phthalimidoperoxycaproic acid

Phthalimidoperoxycaproic acid (CAS 128275-31-0), also known commercially as Eureco HC, is a peracid-based oxidizing agent used primarily as a bleaching and antimicrobial active in formulated systems. It delivers controlled oxidative action at lower temperatures than conventional peroxide bleaches, making it commercially relevant where process efficiency and substrate compatibility are priorities.

In textile and laundry processing, it functions as a low-temperature bleach active incorporated into detergent formulations to remove stains and brighten fabrics without requiring elevated wash temperatures. Leather and paper manufacturers use it for oxidative bleaching of substrates where gentler chemistry reduces fiber or surface degradation. In personal care, it is evaluated as a biocidal and whitening active.

This chemical is utilized in rinse-off and leave-on formulations targeting hygiene and brightening performance. Pharmaceutical and healthcare product developers have explored it as a disinfection and preservation active. It is frequently applied in surface and instrument cleaning applications. Phthalimidoperoxycaproic acid is typically supplied as a white to off-white powder available in technical grade for industrial cleaning.

Purity specifications vary by intended end use. Packaging is generally offered in small laboratory quantities through to bulk industrial volumes depending on supplier capability and specific requirements.
