Description

Cationic color-protecting composition and color-protecting hair conditioner containing same

Technical Field

The invention relates to the field of hair conditioners, in particular to a cationic color protecting composition and a color protecting hair conditioner containing the composition.

Background

The simple and easy cosmetic means brings colorful life to us and brings some trouble to us at the same time of dyeing hair: why does freshly dyed hair "dulled out" for a long time? This has become a frequent complaint of consumers. How to keep the color after dyeing longer, which hair products have color protection function and how to verify the color protection claim of the products are popular research directions.

The permanent hair dyeing process can be briefly summarized as: the alkaline component in the hair dye opens the hair scale of the hair, the dye small molecular precursor, the dye coupling agent and the oxidant penetrate into the cortex layer of the hair together, oxidation condensation reaction occurs there, the dye small molecular precursor is oxidized and condensed into macromolecules with the dye coupling agent, and the macromolecules stay in the epidermis and the cortex layer of the hair fiber to display target color. Consumers who use permanent hair dyes generally want the hair to be permanently dyed or they want the bright color after dyeing to be maintained for a longer period of time to reduce the frequency of dyeing. In fact, however, neither hair dye permanently retains the color. The unavoidable factors such as hair washing, hair waving, sunlight irradiation and the like can cause the color of the dyed hair to drop and the luster to be reduced, wherein the hair washing and hair care is the first big 'basic murder' for causing the color drop after dyeing. In the hair washing and caring process, the short carbon chain surfactant in the common shampoo and the hair conditioner not only can increase the solubility of the dye in water, so that the dye is gradually transferred into the water from the surface of the hair, but also can open the hair scales, so that a large amount of dye in the hair conditioner is lost. In addition, damage to the hair surface and the resultant porous structure of the hair scale surface also accelerates dye loss. At this time, the decolorization effect of the shampoo and the conditioner is particularly remarkable. Some have been subjected to even two shampooing processes, the color of which has been far from the original post-dyeing color. Sunlight is also one of the causes of hair discoloration after dyeing. Ultraviolet rays in sunlight can damage hair fibers and hair scales, so that the hair scales are tilted, and the pores on the surfaces of the fibers are increased, thereby accelerating the falling of dyes in hair.

Currently, commercially available color-protecting alleged conditioners are less on the market, and most products are imported products, and have differences in applicability to asian hair quality. In addition, the existing commercial color-protecting hair conditioner still has certain defects in the formula structure, the formula cationic emulsifier is similar to the conventional hair conditioner in selection, and the quaternary ammonium salt of C16 or C18 is used, so that the short carbon chain cationic surfactant has strong surface activity, and the solubility of dye molecules in water can be increased, so that the dye permeates into the water from the hair surface layer; meanwhile, the short carbon chain cationic quaternary ammonium salt has no obvious effect on hair restoration, and long-term use of the short carbon chain cationic quaternary ammonium salt can not only play a role in color protection, but also continuously destroy hair scales and deepen the hair frizziness. In addition, one method of preventing post-dye fading in existing commercial color protection conditioners is to slow down the fading by simply adding an ultraviolet absorber. By combining with analysis of dye fading influence factors, the addition of an ultraviolet absorber can only weaken the color drop caused by sunlight irradiation, and cannot effectively slow down the drop of the dyed color integral caused by other factors. According to a permanent dye paste durability test method, the delta E total color difference change is measured, the color protection rate is calculated, and the fact that the existing color protection hair conditioner has the color protection rate of only 10-15% in the color protection performance is found, so that the requirements of consumers can not be met.

Experimental example

The color conditioner ingredients containing cationic color care compositions prepared in examples 1-4 are listed in table 1 below:

TABLE 1 composition of different color conditioner

In order to prove the beneficial effects of the cationic color-protecting composition-containing color-protecting hair conditioner, the following design experiment is carried out on the color-protecting hair conditioner and the commercially available similar color-protecting hair conditioner:

1. conditioning performance (comb, softness, moisturization, etc.) of hair conditioner was evaluated by hair salon half-head test (Halftest)

2. The contact angle (contact angle) of the hair conditioner on the dyed hair surface was measured, the contact angle reflects the hydrophobicity of the hair, which is a hair damage mark, and the corresponding result of the contact angle change is as follows:

+ contact angle = increased contact angle, reduced hydrophobicity, and hair restored

- Δcontact angle = reduced contact angle, enhanced hydrophobicity, damaged hair

3. The combing performance and the tensile strength of the color-protecting hair conditioner and the commercially available similar color-protecting hair conditioner are measured by a universal tester

4. The color difference of the dyed hair after care using the present invention was compared using an x-rite color difference meter for permanent dyeing (Color Fading Experiment of Permanent Hair Dye) test, characterized by the color difference symbol Δe, which is defined as the total color difference of the sample, the greater the Δe number, indicating a greater color difference and a lower degree of color protection. The corresponding results of the color difference calculation formula and the variation are as follows:

ΔE＝[△L^2+△a^2+△b^2]^1/2

the larger ΔE, the greater the color difference, indicating a higher degree of hair color fade;

the smaller ΔE, the smaller the color difference, indicating a lower degree of hair color fade;

wherein L, a, b have the meanings: l represents color brightness, a represents color redness-greenness, and b represents color yellowness-blueness.

The color protection rate is calculated through the change of the total color difference delta E, and the calculation formula is as follows:

color retention% = [ (Δe control- Δe experiment)/Δe control ] x100%

The color conditioner and the commercial color conditioner provided in examples 1 to 4 of the present invention were used as comparative examples (comparative example 1 is commercial 1, comparative example 2 is commercial 2), and are specifically as follows:
