Product Information
AOS 35% liquid Package:200kg 4200 AOS 98% powder Package :25kg/bag 11500 Surface activity AOS, like other anionic surfactants (such AS LAS, As, AES, etc.), also has excellent surface activity. Within a certain concentration range, AOS can reduce the surface tension of water from 72 mn.m-1 to about 30-40 mn.m-1. The critical micelle concentrations (cmc) of several anionic surfactants measured by the surface tension method at 25℃ are as follows: The following table shows the critical micelle concentrations (cmc) of several anionic surfactants. Name: Sodium Laurate K12 LAS AOS14-16 AOS14-18 AOS16-18 Cmc 5.3 2.3 0.65 0.60 0.40 0.20 Solubility Under the same conditions, the AOS of C12, C14, C16 and C18 were determined respectively. With the increase of carbon chains, the solubility decreased. However, it has good solubility within a relatively wide range of carbon numbers (C12-C18). AOS with a carbon number distribution of C14 and C16 has good solubility and can be used in liquid detergents. Wetting force At room temperature of 27℃, the surfactant was prepared into a 0.1% deionized aqueous solution, and the wetting time of several surfactants was measured by the immersion method. The order of wetting force from large to small is as follows: LAS>AOS14-16>AES≈K12>AOS14-18>MES Foaming property Anionic surfactants such as AOS, LAS, K12, and AES all have good foaming power. In comparison, AOS14-16 and AES have better foaming properties. Resistance to hard water Titrate the surfactant solution with CaCl2 solution, and take whether the solution is turbid as the endpoint to determine. The order of the anti-hard water ability (calculated as cacO3) of several surfactants from weak to strong is: K12 Calcium soap dispersion power Based on the acid titration method and turbidimetric method, the calcium soap dispersion characteristics of surfactants such as α -enyl sulfonate and fatty acid methyl ester sulfonate were determined at 40℃ and room temperature of 20℃ respectively. The order of dispersion power from weak to strong was: LAS Decontamination power The anionic surfactant 16%, sodium tripolyphosphate 18%, soda ash and sodium silicate, etc. in the phosphorus-containing laundry powder are added in accordance with the requirements of the national standard for laundry powder.
