Product Application of Trideceth-4 CAS#69011-36-5
As an APEO-free non-ionic surfactant, trideceth-4 boasts dependable wetting, oil-cleansing and emulsifying traits. It is widely adopted within industrial-strength cleaning agents for hardware washing, textile pretreatment and surface-oil elimination on metal workpieces.
The compound works well in mixed surfactant systems for daily-use detergents and textile auxiliaries. Thanks to its stable performance under hard-water circumstances, it can serve as an emulsifier for coating additives and agrochemical formulations. Being the environmentally-safe substitute for alkylphenol polyoxyethylene ether, it also gets utilized in leather processing and fine-chemical processing to cut surface tension of liquid systems.
