C12-C14 Secondary Alcohol Ethoxylate

Hard surface cleaning

The figure on the right shows an example of hard surface cleaning of various surfactants on ceramic tile surfaces. SECOL series show excellent soil removal efficiency compared with other types of non-ionic surfactants.

Wool Scouring

The figure on the right shows an example of application in wool scouring. No sodium carbonate was added to the test. Lab tank scouring results on 70s wool demonstrates wool scouring performance of SECOL is better than that of primary alcohol ethoxylates and NPE.

Formulations concentrated laundry detergent

Concentrated laundry detergents are formulated according to ref[1]. These sam-ples were stored at room temperature, (40+2)°Cand(0±2)℃ for one month，respectively, and were subjected to cold and heat cycles for24 hours at (40±2)°C and (-5±2)°C respectively. The results show that there was no significant difference in the state of the samples before and after the tests, which indicates that secondary alcohol ethoxylates SECOL-90 and SEC-OL-70 had good compatibility with other raw materials. The results also indicate thatSECOL-90 and SECOL-70. instead of AEO-9, AEO-7 used to concentrate laundry liquid formula can reduce the amount ofsolvent added in the formula.

Detergency

As shown in the chart. there is no signifi-cant difference in the detergency of three types of alcohol ethoxylates to sebum cloth,and the detergency of SECOL products and branched C13 ethoxylate to carbon black cloth are almost the same, higher than oleo ethoxylate. The results also indicate that solvents play minimum role of detergency in formulations thus their doeage should be limited in laundry formulations.
