Development Of Soft-supple Shampoo And Conditioner

Now most of the shampoo and conditioner mainly use a lot of silicone oil to achievesuperior conditioning performance. However, too much conditioning ability wasn’t needed byour hair. Some strong conditioning agent, such as silicone oil, will cause itching of head andother issues. In this paper, soft-Supple shampoo and conditioner are developed throughexperiment according to the design principle of shampoo and conditioner formula.Based on the design principle of shampoo formula, we mainly study the primarysurfactants, secondary surfactants, thickening system, emollient for hair, active protein forhair, the lipid components for hair repair, etc. From experimental test and literature, wechoose SLES as the main surfactant, CAB30as the secondary surfactant, Sodium Chloride andcomplex Versathix as thickening system, Cromollient SCE as emollient for hair,Hydrotriticum QM as active protein for hair, Cutissential18-MEA40as the lipid componentsfor hair repair.According to the previous studies, formula32of soft-supple shampoo was developed.When formula32is compared to commercially available shampoo C, there is littleperformance difference in conditioning, detangling. Salon test results demonstrate that thereare essentially no differences in the attributes tested between shampoo C and formula32. Thetest based on QB/T1974-2004and the stability test on formula32show that formula32meets the designed requirement.The Rejuvasoft conditioning system which is patented by Croda is used to develop soft-supple conditioner. When Rejuvasoft conditioner, formula33, is compared to a leading brandconditioner, there is little performance difference in softness, conditioning, detangling. A half-head, double-blind study was conducted on forty-nine panelists by a cosmetologist in salontest. Salon test results demonstrate that there are essentially no differences in the attributestested. After the half-head evaluation, panelists were asked which side they preferred (forcedpreference). The result shows that the population could not discern a difference inperformance between these two conditioners. The test based on QB/T1975-2004and thestability test on formula33show that formula33meets the designed requirement.
