OP-7.5(X-114)
Jienuo
Emulsifier OP - 7.5, also known as Alkylphenol polyoxyethylene (7.5) ether, is a non - ionic surfactant. It has excellent emulsifying properties, enabling it to effectively disperse oil in water, forming stable emulsions. Widely used in various industrial fields, such as textile auxiliaries, where it helps with dyeing and finishing processes. It also serves as a cleaning agent in metal processing, removing oil and dirt. Additionally, it can be applied in the production of pesticides and cosmetics for its good compatibility and solubilizing ability.
Product Advantage
Outstanding Emulsifying Ability: Emulsifier OP - 7.5 exhibits remarkable emulsifying performance. In industrial tests, it can emulsify 95% of common oils within 30 seconds, forming stable emulsions that remain intact for over 72 hours, which is far superior to many ordinary emulsifiers.
Wide Compatibility: It shows excellent compatibility with various ionic and non - ionic surfactants. When compounded with anionic surfactants, the synergistic effect can increase the cleaning efficiency by 30%, making it highly flexible in formula design.
Strong Temperature Adaptability: It maintains stable performance in a wide temperature range of - 10℃ to 120℃. Even at high temperatures of 100℃, its emulsifying activity only decreases by 5%, suitable for various harsh process conditions.
Low Foaming Property: During use, it generates low foam. In foam height tests, the foam height is only 15mm after 5 minutes of agitation, which is beneficial for processes requiring low - foam operation, such as textile dyeing and metal cleaning.
