Interpretation of result:
As can be seen from Figure 2, general only contains the trolamine ester based quaternary ammonium salt as the softening agent product of softening agent raw material, and the softening agent product that especially contains the ester based quaternary ammonium salt of lower concentration just has the hydrolysis phenomenon to take place after 4 to 6 weeks.Along with the shelf time is more long, the hydrolysis phenomenon is also just more obvious.After preserving 3 months under 40 ℃ the environment (be equivalent under the normal temperature 18 months), the hydrolysis phenomenon is apparent in view, phenomenons such as breakdown of emulsion, layering occur, and its color and luster also remarkable improvement can take place.After preserving 3 months under 4 ℃ of environment, gelatin phenomenon will appear immediately.
And four kinds of softening agent products of the present invention preparation are deposited in any environment and were not had obvious variation in three months, especially keep three months under 40 ℃ high temperature and proterties does not have too big change.
Generally speaking, preserve after three months, more significantly hydrolysis all can take place in the softening agent of ester based quaternary ammonium salt type under the environment of 4 ℃ and 40 ℃.And softening agent product of the present invention above said hydrolysis phenomenon just can occur when will deposit 4.5 months to 5 months under 40 ℃ environment.
As shown in Figure 3, the viscosity of softening agent product 2 under each temperature is all highly stable.Especially, after the stability test in 24 weeks finishes, be in three kinds of softening agents under the temperature and breakdown of emulsion, layering or gelatin phenomenon all do not occur.Just the specimen under 40 ℃ of conditions has the color phenomenon of yellowing slightly that shoals, but does not influence its use properties and stability.
In Fig. 6, there is the phenomenon of a small amount of partial hydrolysis in softening agent product 4 in the starting stage, but along with time lengthening, the viscosity of softening agent under each temperature all convergence is stable.Even under 40 ℃ test condition, the hydrolysis degree of product 4 is obviously than a little less than the common ester based quaternary ammonium salt.
In Fig. 7, shelf time of softening agent product 1 is extended to 5 months, all convergence is stable under each temperature for product 1.Especially in this product the 24th when test week under 4 ℃ of conditions,, its viscosity still can remain on about 168ps, and 170cps compares with initial value, changes in 5% stable performance.And the general softening agent product (as shown in Figure 2) that only contains trolamine ester based quaternary ammonium salt type, especially contain the softening agent product of ester based quaternary ammonium salt of lower concentration after 3 months, particularly under the environment of 4 ℃ and 40 ℃, tangible demixing phenomenon occurs, can't proceed viscosity test.This contrast experiment illustrates that the stability of the product that uses this patent softening agent raw material has significant advantage.
Though in the selection of different material or the product of under different conditions of mixture ratios, producing can have the certain limit gap at resistance to hydrolysis, but through comparing with the product that only contains common trolamine ester based quaternary ammonium salt, product of the present invention can have very remarkable advantages in stability and resistance to hydrolysis.
