Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has an excellent conditioning effect on hair damaged by chemical treatments such as permanent hair dye, hair dye, hair bleach, etc., and is easy to use. This invention relates to a detergent composition that has significantly reduced irritation to the skin.

In today's world, hair is becoming more easily damaged due to changes in the social environment such as an increase in the number of chemical treatments for hair, an increase in the number of hair washes, hair stains due to air pollution, and drying of hair due to air conditioning, etc. In this day and age, shampoos are required to have functions. Also, just foaming property,
Not only does it have cleaning properties, but it also has a conditioning effect on the hair (making it less likely to damage the hair, protecting damaged hair, making it easier to run your fingers through the hair during washing and rinsing, making the hair less squeaky, and making the hair more manageable after drying. 〇In order to impart conditioning effects to shampoos, lanolin derivatives and protein derivatives have traditionally been used. , oil-based ingredients such as higher alcohols, humectants such as glycerin, polyethylene glycol/propylene glycol, amphoteric or nonionic water-soluble polymer compounds, natural plant extracts, etc. have been widely used. Since it has poor adsorption power to hair and is mostly washed away during the rinsing operation after shampooing, it has a satisfactory conditioning effect on damaged hair, especially hair damaged by permanent dye, hair dye, hair bleach, etc. I hadn't reached that point yet.

On the other hand, surfactants that have traditionally been added to shampoos as detergents include those used by professionals such as those used in hairdressing salons1, as well as general commercial products such as alkyl sulfate ester salts and polyoxyethylene alkyl esters. Sulfuric ester salts, alkylbensene sulfonates, α-olefin sulfonates, and the like have been widely used. Although shampoos containing these surfactants have excellent cleaning power, they are known to be highly irritating to the skin to varying degrees, and are used by barbers and beauticians. Among professionals who often come into contact with shampoo,
It tends to cause skin disorders such as rough hands. Also, recently, young people who have a particularly developed sense of cleanliness are washing their hair more often, but even the general public is washing their hair 3 to 4 times a week, or every day. Continuously washing your hair with a shampoo containing a highly irritating surfactant can cause problems such as roughness of the scalp, leading to dandruff and itching. From these points of view, there is a strong demand for shampoos that have sufficient conditioning effects and are less irritating to the skin, not only for professional use but also for general commercial use. is the current situation.

The present inventors focused on the above points, and as a result of intensive research into shampoos that have excellent conditioning effects and are less irritating to the skin, they found surfactants with a low protein denaturation rate and surfactant compositions. In contrast, surfactants and surfactant compositions with a low protein denaturation rate can be used repeatedly for long periods of time without causing severe roughness or dandruff. Skin disorders such as rough hands can occur, and the occurrence of dandruff on the scalp can be significantly reduced. It has been found that when stably blended, it is possible to impart excellent conditioning effects while maintaining low skin irritation.

That is, various surfactants and surfactant compositions, and
For samples containing various additives, measurement of protein denaturation rate, roughness test using actual human hands, measurement of amount of dandruff due to actual use (continuous use), practical usability test, hair finish quality Through tests, we have found that by incorporating a certain type of cationic polymer compound into a shampoo composition with a low protein denaturation rate, it has an excellent conditioning effect, is easy to use, and at the same time does not irritate the skin. We have completed the invention of this cleaning composition which has extremely low

The present inventors have discovered that the alkyl alkyl taurine salt type anionic surfactant represented by the above general formula (A) and the trialkylaminoacetic acid betaine type amphoteric surfactant represented by the above general formula (B) are mixed in appropriate amounts. They discovered that phenomena such as an increase in viscosity, an increase in pH, and a decrease in critical micelle concentration were observed when they were mixed at the same molecular weight ratio and when each component was used alone. However, in this mixture, the surfactant abilities such as foaming properties and detergency were as good as those of each substance alone, and at the same time, the protein denaturation rate was lower than that of each substance alone. It was discovered that there was a significant decrease in A suitable molecular weight ratio of (A):(B) is in the range of about 3:2 to about 1:2, and a molecular weight ratio as close as possible to 1:1 is desirable. If the mixing ratio is outside this range or if a large amount of other anionic surfactant is added to disrupt the balance of the system, a sufficient effect of lowering the protein denaturation rate cannot be obtained.

Further, the alkylol, amide type nonionic surfactant represented by the general formula (0>) used in the present invention is

It is.

Next, the present invention will be explained in detail with reference to examples, but prior to that, the test methods and evaluation methods employed in each example will be explained.

OlM: JOB? A sample concentration of 400 ml was prepared using Oppm artificial hard water, and the amount of foaming was measured at a temperature of 0° C. using a cylindrical cylinder equipped with a stirrer.

A solution with a sample concentration of 1% was prepared using OaO/MgO-3/l, 5° DH artificial hard water, and the artificial sebum-contaminated cloth was washed using wool surge.

f Ha: Height of the 220 nm absorption peak of ovalbumin For each sample, 5 men and 5 men each used a total hydration panel, and placed either their left or right hand in an aqueous solution with a sample concentration of 5% and a temperature of ˚C. The other hand was immersed in water at the same temperature for 10 minutes twice a day for two consecutive days, and the difference in rough skin between the left and right hands was visually determined.

I usually use general commercial lauryl ether sulfate shampoo (for dandruff itching), 6 times,
The subjects were asked to wash their hair, and the amount of dandruff was compared before and after using the sample.

The amount of dandruff on the 3rd day after washing your hair with a general commercial shampoo and the final sample after washing your hair 5 times were taken. To eliminate errors caused by other foreign substances, the amount of nitrogen was determined using the Kelpool method.
．． Multiply by 25 to find the average protein amount, and calculate the amount of dandruff (7119
/ head).

The number of panels was three for each sample, and the average values were compared.

The shampoo composition was stored under the conditions of 0°C/25"C and 50"C, and its appearance was observed with the naked eye.

A panel divides the hair into left and right halves, washes one side with a control shampoo, lauryl ether sulfate-based commercially available shampoo, and the other side with a sample at the same time, and checks how well the fingers run through the hair during hair washing and when rubbing, and whether or not the hair is squeaky. A comparative sensory evaluation was conducted.

After the panel washes the hair using the same method as described above (the Mayuzuhed method), the hair is dried, and the results are evaluated, such as how easily the left and right hair clumps together, how supple it is, how dry it is, how stiff it is, and how well it combs. A comparative sensory evaluation was performed.
