Performance test

1. Color locking detection: a section of real hair sample is cut from a hair die, washed and dried by deionized water, and then the sample is dyed by the same red hair dye, 15g of the hair dye is used for dyeing three times each time, and 15 minutes is used for dyeing each time; comparing the dyed color of the sample with the 1797C standard chroma in an RAL international color number comparison table, and recording the initial l, a and b values of the sample; then dividing the sample into two parts, marking the two parts as a sample A and a sample B, uniformly coating the color-locking hair-care essential oil prepared in the embodiment 1 on the sample A, massaging for 5 minutes, washing and drying the sample A by using clear water, and washing and drying the sample B by using the same amount of clear water; and then washing the sample A and the sample B with the same amount of the same shampoo for one time, washing after washing and drying, recording the values of l, a and B detected by a spectrophotometer after the sample A and the sample B are washed for five times and washed for ten times respectively, and finishing the color locking detection test. The essential oils obtained in examples 1 to 10 and comparative examples 1 to 4 were subjected to a color-locking test one by one.

In particular, in the spectrophotometer, l represents the brightness (black and white), a represents red and green, and b represents yellow and blue; the value of l is positive, indicating that the sample is brighter than the standard plate; if the value is a negative value, the value is dark;

the value of a is positive, indicating that the sample is redder than the standard plate; if the value is negative, the value is greenish;

the value of b is positive, which indicates that the sample is more yellow than the standard plate; if the value is negative, the color is blue;

the detailed assay data for the experiments are detailed in tables 4-7 (Δ = sample value-initial value).

TABLE 4

According to the detection data of examples 1-5 in Table 4, in the same batch of samples, the values of delta l and delta a are negative numbers, the glossiness of the samples is reduced, and the reddening of the color is declined; the Δ b value is positive and the sample color shifts toward the hair primary tan. The samples A applied with the essential oils obtained in examples 1 to 5 had larger Deltals and Deltaa than those of the samples B not applied with the essential oils; the Δ B value of the sample A is smaller than the Δ B value of the sample B, which indicates that the change range of the values of the value l, the value a and the value B of the same initial value of the sample A coated with the essential oil prepared in examples 1-5 is smaller than that of the value l, the value a and the value B of the same initial value of the sample B not coated with the essential oil, the gloss reduction rate of the sample A coated with the essential oil prepared in examples 1-5 is slower, the hair fading speed is slower, and the essential oil prepared in examples 1-5 has good color locking capability. And as the number of washing times increases, the difference between the value of the sample a and the value of the sample B increases, and the color locking efficacy of the essential oils prepared in examples 1 to 5 is more remarkable.

Comparing the variation ranges of the values of the sample A, the value a and the value b of the initial comparison value of the sample A in different batches shows that the variation range of the value A of the sample A coated with the essential oil prepared in the examples 3 and 4 is smaller than that of the sample A coated with the essential oil prepared in the examples 1 and 2, which indicates that the color locking capability of the essential oil prepared in the examples 3 and 4 is stronger than that of the essential oil prepared in the examples 1 and 2, and the variation range of the value A of the sample A coated with the essential oil prepared in the example 5 is the smallest compared with that of the initial comparison value, which indicates that the color locking capability of the essential oil prepared in the example 5 is the best.

The inventor analyzes and considers that the components adopted by the raw materials in the example 5 have better associativity among the raw materials in the essential oil, and the synergistic effect among the cyclopentadimethylsiloxane, the crambe abyssinica seed oil and the argania spinosa kernel oil is better, so that the color locking effect of the essential oil is more remarkable.

TABLE 5

According to the detection data of comparative examples 1 to 6 in table 5, in the same batch of samples, the change ranges of the l value, the a value and the B value of the samples a and B coated with the essential oils prepared in comparative examples 1 to 6 compared with the initial values of the samples are similar, which shows that the gloss reduction rate of the samples a and B coated with the essential oils prepared in comparative examples 1 to 6 are similar, and the hair fading speed is similar, and the obvious change ranges of the l value, the a value and the B value of the samples a and B coated with the essential oils prepared in example 5 compared with the initial values of the samples are similar, which shows that the essential oils prepared in comparative examples 1 to 6 have weaker color locking capability and far less lasting color locking effect.

The inventor analyzes and considers that the crambe abyssinica seed oil and the crambe spinosa seed oil penetrate into hair scales of hair, and the crambe abyssinica seed oil molecules are used as nonionic surfactants, so that the surface activation energy of pigment particles can be reduced, and hydrophobic mucous membranes can be favorably adhered to the surfaces of the pigment particles; the argania spinosa kernel oil molecules have good flexibility, so that the hydrophobic mucous membrane has good ductility, the hydrophobic mucous membrane can coat pigment particles in a larger range, cyclopentadidimethyl siloxane has excellent hydrophobicity and is a source of hydrophobic characteristics of the hydrophobic mucous membrane, the hydrophobic mucous membrane generated by the combined action of the cyclopentadidimethyl siloxane, the water and the water molecules coats the pigment particles into a plurality of hydrophobic pigment particle groups in the hair scales, the effect of blocking the pigment particles and the water molecules is achieved, the phenomenon that the pigment particles are lost from the hair scales along with the water molecules is reduced, the pigment particles are stabilized in the hair scales, and the essential oil has color locking capability.

TABLE 6

According to the test data of examples 5 to 9 in table 6, it can be seen that by comparing the variation ranges of the value l, the value a and the value b of the initial value of the comparison of the sample a in different batches, the variation range of the value of the sample a coated with the essential oil obtained in example 5 is larger than that of the sample a coated with the essential oil obtained in examples 6 to 9, which indicates that the effect of the butyl stearate as the softener on the color-locking effect of the essential oil is smaller in example 5, and the effect of the mixture of cyclohexasiloxane and dimethiconol as the softener in example 6 or the mixture of cyclohexasiloxane and butyl myristate as the softener in examples 7 to 9 on the color-locking effect of the essential oil is better.

The numerical variation range of the sample A coated with the essential oil prepared in example 6 is larger than that of the sample A coated with the essential oil prepared in example 7, which shows that the gain effect on the color locking effect of the essential oil generated by using the mixture of the cyclohexasiloxane and the dimethiconol as the softener is smaller than the gain effect on the color locking effect of the essential oil generated by using the mixture of the cyclohexasiloxane and the butyl myristate as the softener.

The range of values for sample a applied with the essential oil obtained in example 7 was greater than the range of values for sample a applied with the essential oils obtained in examples 8 and 9, indicating that the essential oil obtained in example 7 in a ratio of the mass ratio cyclohexasiloxane to butyl myristate of 0.5.

The inventor analyzes that the cyclohexasiloxane and the dimethiconol can be mixed to form an adsorption film with better ductility, the adsorption film and a hydrophobic mucous membrane formed by cyclopentadimethicone, crambe abyssinica seed oil and argania spinosa seed oil are adsorbed and fused to a certain extent, and a plurality of hydrophobic color clusters are fused on the adsorption film, so that the coupling property among the hydrophobic color clusters is enhanced, the stability of the hydrophobic color clusters in the hair scales is enhanced, and the color locking effect of the essential oil is improved.

When the cyclohexasiloxane and the butyl myristate are mixed and act together, a continuous adsorption film can be formed, particularly, when the cyclohexasiloxane and the butyl myristate act together within the mass ratio range of (1.2-1.5): 1, the butyl myristate and the cyclohexasiloxane can be fully combined to form the adsorption film, the structural performance of the adsorption film is better, the adsorption strength is greater than that of the adsorption film formed by mixing the cyclohexasiloxane and the dimethiconol, the coupling property between hydrophobic color clusters can be better enhanced, and the color locking effect of the essential oil is improved; beyond this range: the bonding rate of the cyclohexasiloxane and butyl myristate is reduced, and the number of generated adsorption films is small; more cyclohexasiloxane exists, and the self-lubricating property of the cyclohexasiloxane reduces the adsorbability of an adsorption film formed by the cyclohexasiloxane and the cyclohexasiloxane, so that the cyclohexasiloxane and the adsorption film are not favorable for adsorbing hydrophobic color clusters.

TABLE 7

From the test data in Table 7, example 5 and example 10, it can be seen that the range of values for sample A for the essential oil obtained in example 5 was greater than the range of values for sample A for the essential oil obtained in example 10, indicating that the color locking ability of the essential oil obtained in example 5 using sodium carboxymethylcellulose as the thickening agent was less strong than that of the essential oil obtained in example 10 using the polyvinyldimethicone/polymethylsilsesquioxane crosspolymer as the thickening agent.

The inventor analyzes and considers that compared with other thickening agents, the vinyl polydimethylsiloxane/polymethylsiloxane silsesquioxane cross-linked polymer has a better effect of enhancing the adhesion between the adsorption film and the hydrophobic mucous membrane, so that the color locking effect of the essential oil is better enhanced, the connectivity among raw materials in the essential oil is improved, and the essential oil is durable.

TABLE 8

According to the test data of example 5 and examples 11 to 13 in Table 8, it can be seen that the range of the value of sample A applied with the essential oils obtained in examples 11 to 13 is smaller than that of sample A applied with the essential oil obtained in example 5 by comparing the variation ranges of the value of sample A to the value of the initial value of value l, value a and value b in different batches, which indicates that the color-locking ability of the essential oils obtained in examples 11 to 13 is stronger than that of the essential oil obtained in example 5.

The inventor analyzes and considers that the raw materials in the embodiments 11 to 13 have good combined connection effect, the hydrophobic mucous membrane generated by the synergistic effect of the cyclopentadienylmethane siloxane, the crambe's purse oil and the argania spinosa kernel oil has more comprehensive coating on pigment particles in hair, the color locking capability is stronger, the adsorption membrane generated by the synergistic effect of the cyclohexasiloxane and the butyl myristate has obvious gain effect on the hydrophobic mucous membrane, the color locking effect of the essential oil is further improved, and the thickener and the bis-aminopropyl polydimethylsiloxane in the raw materials play good roles, so that the better embodiment of the application is obtained.
