Detailed Description
The following specific embodiments are provided to further illustrate the present invention, but the present invention is not limited to only the following embodiments.
The inventor of the patent finds that the polyethylene glycol-120-methyl glucoside trioleate and the polyethylene glycol-120-methyl glucoside triisostearate are jointly used, so that a system taking an amino acid surfactant as a main surfactant can be effectively thickened, the thickening effect is not the simple superposition of the effects when the polyethylene glycol-120-methyl glucoside trioleate and the polyethylene glycol-120-methyl glucoside triisostearate are used independently, but the combination of the polyethylene glycol-120-methyl glucoside trioleate and the polyethylene glycol-120-methyl glucoside triisostearate generates a strong synergistic effect, the viscosity of the system is remarkably and greatly improved, and an unexpected and good thickening effect is achieved.
The invention provides a thickening agent aiming at an amino acid surfactant, which consists of polyethylene glycol-120 methyl glucoside trioleate and polyethylene glycol-120 methyl glucoside triisostearate, wherein when the mass ratio of the polyethylene glycol-120 methyl glucoside trioleate to the polyethylene glycol-120 methyl glucoside triisostearate is 1:1-3, an ideal synergistic thickening effect is achieved.
The thickener of the present invention can be used for thickening a system having as a main surfactant at least one amino acid surfactant selected from the group consisting of lauroyl sarcosinate, cocoyl sarcosinate, lauroyl alaninate, cocoyl alaninate, lauroyl glutamate, cocoyl glycinate, methyl cocoyl taurate, cocoyl methyl taurate, and the like. The thickening agent has good thickening effect on various amino acid surfactants and combinations thereof, and has no selective thickening phenomenon with large difference.
The thickener of the invention can be used in transparent formulations, enabling the development of transparent products.
The thickener can be used for producing shampoo products which take amino acid surfactants as main components, in particular transparent shampoo products. The prepared shampoo product is mild and non-irritant, and has good stability and use feeling.
The addition amount of the mixed thickener in the shampoo is 1-6% of the total mass of the shampoo.
The present invention will be further illustrated with reference to the following specific examples, but the present invention is not limited to the following examples.
The experimental procedures used above and in the examples below are conventional unless otherwise specified.
The materials, reagents and the like used above and in the following examples are commercially available unless otherwise specified.
Example 1
Thickening Performance test
Different surfactants and different addition amounts are selected, so that the detersive power, the use feeling and the like of a formula system are influenced to a certain extent, and under the premise of the characteristics of the raw materials, the frequently used amino acid surfactants comprise sodium lauroyl sarcosinate (30 percent of content), sodium cocoyl alanine (30 percent of content), sodium methyl cocoyl taurate (30 percent of content) and the like. Now taking the three amino acid surfactant systems described above as examples, the effect of PEG-120 methyl glucoside trioleate and PEG-120 methyl glucoside triisostearate on system viscosity when added separately and mixed, respectively, was tested. The sodium methyl cocoyl taurate has a certain influence on the transparency, so the addition amount of the sodium methyl cocoyl taurate cannot be too large.
The amino acid surfactant system for testing comprises the following components in parts by mass:
20 parts of sodium lauroyl sarcosinate,
20 parts of cocoyl alanine sodium,
10 parts of sodium methyl cocoyl taurate.
The experimental steps are as follows: adding weighed distilled water into a beaker, adding 20 parts of sodium lauroyl sarcosinate, 20 parts of sodium cocoyl alanine and 10 parts of sodium methyl cocoyl taurate, heating to 80-85 ℃, and dissolving and stirring uniformly. Then, a certain amount of PEG-120-methylglucoside trioleate and PEG-120-methylglucoside triisostearate were added according to the following experiment and dissolved and stirred uniformly. Then, water was added to 100 parts, and the viscosity of the system was measured (25 ℃, 3#, 12 rpm). The addition amounts referred to in the experiments are in parts by mass.
Experiment one:
the addition amount of the polyethylene glycol-120 methyl glucoside trioleate is as follows: 0 part of (A).
The addition amounts of polyethylene glycol-120 methyl glucoside triisostearate are respectively as follows: 1 part, 1.5 parts, 2 parts, 2.5 parts, 4 parts, and 6 parts.
The viscosities obtained were respectively: 291mPa.s, 506mPa.s, 689mPa.s, 909mPa.s, 1691mPa.s, 3210 mPa.s.
Experiment two:
the addition amount of the polyethylene glycol-120-methyl glucoside triisostearate is as follows: 0 part of (A).
The addition amount of the polyethylene glycol-120 methyl glucoside trioleate is respectively as follows: 1 part, 1.5 parts, 2 parts, 2.5 parts, 4 parts, and 6 parts.
The viscosities obtained were respectively: 193mPa.s, 400mPa.s, 500mPa.s, 808mPa.s, 1295mPa.s, 2406 mPa.s.
As can be seen from experiments one and two: polyethylene glycol-120 methyl glucoside triisostearate and polyethylene glycol-120 methyl glucoside trioleate have certain thickening effect when being added independently, and the viscosity can be increased along with the increase of the adding amount; and the thickening effect of PEG-120 methyl glucoside triisostearate is better than that of PEG-120 methyl glucoside trioleate.
Experiment three:
the addition amounts of PEG-120-methylglucoside trioleate and PEG-120-methylglucoside triisostearate are the same, and the total addition amount is as follows: 6 portions of (2) to (3) to (4) to (5).
The viscosities obtained were respectively: 980mPa.s, 1813mPa.s, 2593mPa.s, 3405mPa.s, and 3750 mPa.s.
Combining the first experiment and the second experiment, the third experiment shows that: when PEG-120 methyl glucoside trioleate and PEG-120 methyl glucoside triisostearate are added simultaneously, the obtained viscosity is not only obviously higher than the viscosity when the PEG-120 methyl glucoside trioleate and the PEG-120 methyl glucoside triisostearate are added separately (see that the viscosity of 2 parts, 4 parts and 6 parts in the experiment I and II is compared with the viscosity of 2 parts, 4 parts and 6 parts in the experiment III respectively), but also is obviously higher than the simple numerical value addition of the viscosity when the PEG-120 methyl glucoside trioleate and the PEG-120 methyl glucoside triisostearate are added separately (see that the viscosity obtained by 1 part, 1.5 parts, 2 parts and 2.5 parts in the experiment I and II is compared with the viscosity obtained by 2 parts, 3 parts, 4 parts and 5 parts in the experiment III respectively).
Therefore, the thickening effect of the polyethylene glycol-120-methyl glucoside trioleate and the polyethylene glycol-120-methyl glucoside triisostearate when used simultaneously is not the simple superposition of the effects when the polyethylene glycol-120-methyl glucoside trioleate and the polyethylene glycol-120-methyl glucoside triisostearate are used independently, but has strong synergistic interaction, so that the viscosity of a system is remarkably and greatly improved, and an unexpected and good thickening effect is obtained.
Example 2
Influence of different proportions on thickening effect
Amino acid surfactant systems for testing the viscosity of the system (25 ℃, 3#, 12rpm) were tested by adding polyethylene glycol-120-methylglucoside trioleate and polyethylene glycol-120-methylglucoside triisostearate, respectively, in the same proportions as in example 1, following the experimental procedure of example 1. The addition amounts referred to in the experiments are in parts by mass.
4 parts of polyethylene glycol-120 methyl glucoside trioleate and polyethylene glycol-120 methyl glucoside triisostearate in proportion: and (2): 1 and 2, 1:1- (1): 2, 1: 3, 1: 4.
the viscosities obtained were respectively: 1769mPa.s, 2593mPa.s, 2796mPa.s, 2602mPa.s, 1838 mPa.s.
From the above experiments it can be seen that: the mass ratio of the polyethylene glycol-120-methyl glucoside trioleate to the polyethylene glycol-120-methyl glucoside triisostearate is approximately 1: about 2, the synergistic thickening effect is most desirable. Meanwhile, the viscosity of the mixture is 1295mPa.s and 1691mPa.s when 4 parts of the mixture is independently added in the first experiment and the second experiment, and the mixture ratio is 1:1 to 1: 3, the synergistic thickening effect is ideal, and the system viscosity is obviously improved.
Therefore, in the actual use process, the thickening effect is better by adopting two compounding forms of polyethylene glycol-120-methyl glucoside trioleate and polyethylene glycol-120-methyl glucoside triisostearate; the mass ratio of the two is approximately 1:1 to 1: 3, the viscosity can be set, and simultaneously, less raw materials are used, so that the cost is saved and the influence on the use feeling of the product is reduced.
The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
