Foaming performance of blend system of sodium fatty alcohol ether carboxylate and iso - fatty alcohol - polyoxyethylene ether
摘要
Abstract
Foaming performance of the blend system of sodium fatty alcohol ether carboxylate (C 12 ~ 14 E9 C)and iso - fatty alcohol - polyoxyethylene ether (IC 10 EO8 )were measured by Ross - Miles method. The results showed that the blend system exhibits high foaming power,and the surface energy of the system is the lowest when the mass ratio of C12 ~ 14 E9 C to IC10 EO8 is 6 ∶ 4 and the mass concentration is 2 g / L. As the mass concentration is further increasing,the foam stability of the blend system becomes declining obviously. The blend system exhibits strong resistance to hard water. Its foaming power and foam stability do not change when the water hardness is less than 400 mg / kg. Addition of salt shows no impact on the foaming power of the blend system,but 0. 5% sodium chloride and trisodium citrate can reduce its foam stability. Foaming power of the blend system increases with the temperature increasing,while the foam stability declines. Foaming power of the blend system increases with pH increasing. When pH of the system is higher than 5,its foaming power remains basically unchanged;and when pH is within 3 - 9,no significant change exhibits on its foam stability.关键词
