Therefore, a double-agent type hair dyeing foam has appeared in the market, and a hair dyeing foam obtained by pumping a mixed solution of a primary hair dyeing agent and a secondary hair dyeing agent from a non-aerosol type foaming container can be lightly and uniformly coated on hair to achieve a uniform hair dyeing effect, but the phenomenon that the foam disappears to form a mixed solution in the hair dyeing process, drops and the like is avoided, so that the hair dyeing experience is poor, and the risk of contacting with the scalp is increased.
At present, there are many researches on two-part type foam hair dyes, such as patents CN103079532A, CN108245435B, CN103957877B, etc., which all propose a formula or composition of foam hair dyes with good foamability and foam stability, but all are applied in a formula of hair dye; patent JP2020180084A provides a composition containing stannate, anionic surfactant and zwitterionic surfactant, which according to the patent content can be used either as a one-part hair dye or as a two-part hair dye, but with anionic surfactant, further irritation may be induced or the dyeing ability may be reduced; KR20190051793A also provides a foam type hair dye composition which can be used in one or two-part hair dyeing, and can form softer hair dyeing foam and better dyeing quality by containing polyquaternium-55, shea butter and glyceryl stearate, but there is no mention about the stability of the two-part hair dye added with the composition.

Effect example 1
This effect example investigated the stability of the two-agent hair dye prepared in examples 1 to 12 and comparative examples 1 to 6 under high and low temperature conditions, in which the product was placed in an oven at 45 ℃ and the product was placed in an oven at-18 ℃ for one week and then evaluated by visual observation to confirm whether or not delamination occurred; wherein, 5 points represent no change, 4 points represent layering after 5 days, 3 points represent layering after 3 days, 2 points represent layering after 1 day, and 1 point represents layering after 1 day without placing in an oven at normal temperature; specific results are shown in table 1; the commercial product is a certain S-brand bubble hair dye color developing application milk, the commercial product in effect examples 2-3 adopts the same commercial product as the product in effect example 1, namely the certain S-brand bubble hair dye color developing application milk as a second hair dye agent, and then the first hair dye agent and the second hair dye agent are mixed according to the mass ratio of 1:1 to obtain the hair dye for testing, wherein the first hair dye agent is the first hair dye agent used in the embodiment and the comparative example of the invention;

Figure BDA0003549238540000091
Figure BDA0003549238540000101
As can be seen from the table 1, the hair dye agent II obtained by adopting the technical scheme of the invention has excellent stability at high and low temperatures; when any one or two of alkyl amidopropyl dimethylamine, fatty alcohol polyether and higher fatty alcohol are not added, the stability of the obtained product is greatly reduced, the obtained product can be layered after being placed at room temperature for one day, and the stability of the obtained product also shows a trend of reduction when the polymerization degree of the fatty alcohol polyether is reduced or branched fatty alcohol is used; meanwhile, comparing the high and low temperature stability of examples 1 to 12 of the present invention with those of commercially available products, the commercially available products were equally good in low temperature stability, but delamination occurred already at 1 day of the high temperature test.
Effect example 2
This effect example explores the properties of the foams produced by the hair dyes prepared in examples 1 to 12 and comparative examples 1 to 6, wherein the density of the foam is calculated by measuring the weight of 50mL of the foam; after 30min, the accumulated liquid is obtained by taking 10g of foam, standing in a beaker for 30min, sucking out the foam by using a suction pipe for 30min, accumulating liquid at the bottom and measuring the mass of the liquid;
the resulting test data are shown in table 2;

Figure BDA0003549238540000102
Figure BDA0003549238540000111
As can be seen from the table 2, the hair dye obtained by the invention has less effusion in the test process, less than 5.92g, high foam density, more than 0.0613g/mL and good stability, which indicates that the foam is not easy to reduce, i.e. not easy to drip, and has good use experience in the actual use process; when no fatty alcohol polyether or higher fatty alcohol is added in any of comparative examples 1-2, compared with example 1, the foam density obtained in comparative examples 1-2 is obviously reduced, the liquid loading is obviously increased, and even when no alkylamidopropyldimethylamine is added in comparative examples 3-4, the obtained hair dye can be separated out and float upwards, and cannot be shaken up for testing; from the data of example 2 and examples 7-9, it can be seen that when the content of the added alkylamidopropyldimethylamine, fatty alcohol polyether or higher fatty alcohol is outside the preferred range of the present invention, the foam density of the resulting hair dye formulation is significantly reduced, with a reduction of between 9.32 and 19.55%; as can be seen from example 6 and comparative example 5, when the degree of polymerization in fatty alcohol polyether was changed to 10, the liquid loading of the resulting product increased significantly, the liquid loading obtained in comparative example 5 was 1.34 times the weight of the liquid loading of example 6, and the foam density in comparative example 5 also tended to decrease compared to example 6; as can be seen from example 6 and comparative example 6, when the higher aliphatic alcohol used was the branched aliphatic alcohol, the amount of accumulated liquid of the resulting hair dye formulation was significantly increased, the amount of accumulated liquid obtained in comparative example 6 was 1.49 times the weight of the accumulated liquid of example 6, and the foam density in comparative example 6 also tended to decrease compared to example 6; meanwhile, the liquid loading of the product obtained by the invention is smaller than that of the product sold on the market, which shows that the overall quality of the foam formed by the product of the invention is better than that of the product sold on the market.

Effect example the evaluation of the hair dyeing ability of the hair dyes prepared in examples 1 to 6 and comparative examples 1 to 2 was investigated, and the resulting foam mixed and pumped out from the hair dye was left on the bundle of white hair for 30 minutes to dye, and then the change in the Lab value of the bundle was measured by a color difference meter and the change in the shade (Δ L value) and the change in the total color difference (Δ E value) were calculated; the results of the tests are shown in table 3;
table 3: hair dyeing agents prepared in examples 1 to 6 and comparative examples 1 to 2 and hair dyeing property test charts of commercially available products
Delta L value Delta E value Delta L value Delta E value
Example 1 -40.912 44.704 Example 6 -40.082 45.56
Example 2 -41.522 45.202 Comparative example 1 -38.426 45.032
Example 3 -41.174 45.852 Comparative example 2 -40.232 44.698
Example 4 -39.504 44.044 Commercially available product -40.862 44.502
Example 5 -40.665 45.632
As can be seen from Table 3, the measured DeltaL and DeltaE values of the hair tresses after dyeing in the examples are very significantly changed, which shows that the hair dye obtained by the invention has certain dyeing capability, and is comparable to or slightly improved from the commercial products.
Finally, it should be noted that the above embodiments are intended to illustrate the technical solutions of the present invention and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
