Detergency of Sodium Alpha-Olefin Sulfonate AOS 35% 92% CAS 68439-57-6
The anionic surfactant 16%, sodium tripolyphosphate 18%, soda ash and soda ash in the phosphorous washing powder are added according to the requirements of the national standard for washing powder. Decontamination experiments of washing powder were carried out on the national standard dirty cloth and bottle decontamination machine, and the order of decontamination power from high to low was as follows:
AES(EO=3)>AOS14-16>AOS14-18>K12>LAS
In the non-phosphorus washing powder, 18% anionic surfactant, 20% 4A zeolite, soda ash and foam alkali, high molecular polymer and other components are added according to the requirements of the national standard for washing powder. Decontamination experiments of washing powder were carried out on the national standard dirty cloth and bottle decontamination machine, and the order of decontamination power from high to low was as follows:
AES(EO=3)>AOS14-16>AOS14-18>K12>LAS
Biodegradability of of AOS 35% 92% CAS 68439-57-6
Among anionic surfactants, their biodegradability deteriorates in the order of AS>AOS>MES>AES>LAS>ABS.
The biodegradation speed and final biodegradability of AOS are significantly higher than that of LAS, and it can be completely degraded and disappeared within 5-7 days in the natural environment without polluting the environment. However, it takes 20-22 days for LAS to be 100% degraded.
