Description

  The present invention relates to a cleaning composition.

  Compositions containing a surfactant as an active ingredient for washing hair, particularly human hair, are widely known. Such compositions are generally one or more selected from conventional surfactants, particularly anionic, nonionic and / or amphoteric type surfactants, more particularly anionic type surfactants. Contains a surfactant. The composition for washing the hair is applied to wet hair and removes the various types of stains initially present in the hair after rinsing with water by foam produced by hand massaging or rubbing. It becomes possible to remove.

  Conventionally, sodium laureth ether sulfate (SLES) has been used as a surfactant in hair cleaning compositions such as shampoos. SLES is known to exhibit good detergent properties. However, SLES tends to roughen human hair and scalp because of its strong surfactant properties.

  Japanese Patent Application Laid-Open No. 2008-214263 includes alkyl ether sulfate, acyl glutamate, amphoteric surfactant, nonionic surfactant, cationic polymer, and polyether-modified silicone, and can reduce irritation to the scalp. A hair cleanser composition is disclosed. Japanese Patent Application Laid-Open No. 2010-235522 discloses a hair cleansing composition that contains an alkyl ether sulfate and an ether carboxylate type anionic surfactant and exhibits reduced irritation properties to the scalp. Japanese Unexamined Patent Publication Nos. 2007-161597 and 2010-159234 disclose hair cleansing compositions that do not contain alkyl sulfates or alkyl ether sulfates. However, there is still a need for hair cleansing compositions that exhibit unstimulation or reduced irritation to the scalp in addition to sufficient cleansing ability.

  In addition, from the viewpoint of environmental protection, particularly in the detergent market, “miniaturization of consumer products” is required. Compact size products can save energy and space. For example, compact size products can save energy to transport products from factory to store, store to home, and also save space needed to store products in warehouses, retail stores and homes Can do. In addition, compact size products can easily be handled by even handicapped or handicapped consumers.

  Regarding the miniaturization of hair cleaning compositions, Japanese Patent Application Laid-Open No. 10-182366 describes anionic surfactants and nonionic surfactants in a special ratio that can increase the surfactant concentration in the hair cleaning composition. Disclosed is a hair cleanser composition that contains a surfactant and also exhibits good foaming and cleansing properties. As a result, the amount of composition used to clean the hair can be reduced. However, the specific examples disclosed in this document include sodium laureth ether sulfate or sodium lauryl sulfate.

  WO 2010/052147 A2 discloses a concentrated shampoo composition comprising an alkali metal alkyl ether sulfate and a short chain diol. However, the anionic surfactant contained in the composition is an alkali metal alkyl ether sulfate (such as SLES). Japanese Patent Application Laid-Open No. 10-53795 discloses a concentrated hair cleansing composition containing glycolic acid N-alkylamide sulfonate ester salt as a main surfactant. JP 2012-207019 discloses a concentrated hair cleansing composition comprising an anionic surfactant in combination with a cationic polymer. However, almost all of the examples of hair cleansing compositions specifically disclosed in that document contain SLES. Formulation Example 2 disclosed in JP 2012-207019 A is 90% lautheth-4 carboxylic acid (30.0% by mass), 30% imidazolium betaine (10% by mass), and 40% as a surfactant. Contains lauryldimethylaminoacetic acid betaine (30% by weight). However, the properties of these types of combinations are not sufficient.

[Protocol for preparing shampoo]
1. Preparation of ether carboxylates. Sodium hydroxide was dissolved in water. Laureth-5 carboxylic acid was slowly added to the solution, which was then mixed uniformly.
2. Dissolve polyquaternium-6 uniformly in a mixture of water and cocamidopropyl betaine. Mix the solution of ether carboxylate prepared in Step 1, disodium laurethsulfosuccinate, disodium cocoylglutamate, caprylyl / caprylglucoside, glycerin, salicylic acid, PEG / PPG-14 / 4 methicone, and fragrance, and dissolve evenly did.
3. The pH of the mixture prepared in step 2 was adjusted to 5.3.
4. If necessary, the viscosity of the mixture obtained in step 3 was adjusted from 50 to 150 mPa.s at 25 ° C. by adding hexylene glycol.

[Protocol for sensory evaluation of composition]
a. Half Head Test The shampoo of the present invention prepared as described above was applied to one side of the head in an amount of 1.5 to 2.0 g according to the amount of hair. Reference shampoo ("Ichigo (product name)" sold by Kracie), SLES-free shampoo), with the same head in an amount of 3.0-4.0 g (approximately twice the amount of the shampoo of the present invention) Applied to the other side. A beauty specialist (n = 4) evaluated the difference between the two sides. Beauty specialists evaluated the results by grading both sides of the head according to a scale from 0 (bad) to 50 (excellent). The number of respondents to this test was 10, and the condition of the subject's hair ranged from those with little damage to those with much damage.

[result]
The following points were evaluated.
(1) Applicability of shampoo: The shampoo of the present invention was applied to hair more easily than the reference shampoo.
(2) Foamability of shampoo: The shampoo of the present invention produced finer bubbles than the reference shampoo. Despite half of the reference shampoo, the initial amount of foam produced by using the shampoo of the present invention was greater than the reference shampoo.
(3) Rinsing properties of shampoo: The shampoo of the present invention was more easily washed out than the reference shampoo.
(4) Conditioning properties of the shampoo: The hair washed with the shampoo of the present invention was well conditioned so that it was easier to pass through the hair than the hair washed with the reference shampoo, whether dry or wet.

b. Evaluation of shampoo performed by consumers This study was conducted to evaluate shampoos in the environment of consumers' daily life, eliminating the skills of beauty salon staff. This test includes two application tests at the beauty salon and one application test at home. The monitor follows the protocol described below.
First visit to the beauty salon:
-The monitor was interviewed about the usual hair care methods and products currently in use. In addition, the monitor was asked about the concepts of “half use” and “foam” shampoo.
-After a short interview, use the test shampoo to wash the hair on the monitor itself, then apply the regular conditioner at home in the way the monitor normally does at home, and then interview the performance of the test shampoo went. The test shampoo was then given to the monitor for testing at home (home use test).
Home (1 week):
-The monitors used their own test shampoo to wash their hair, and the conditioners were routinely used at home at the same frequency. The monitor could use shampoo in such an amount that the monitor felt comfortable.
-The monitor recorded all the dates when the hair was washed at home.
Second and final visit to the beauty salon:
-The monitor washed her hair by using the test shampoo, and the conditioner interviewed about the performance of the test shampoo using the normal one following the same procedure as at home.
Monitor profile:
-9 Japanese women, ages 20-49 years old;
-Users of sulfate-free shampoos with a frequency of more than 5 days per week;
-Hair length: shoulder or longer length;
-Little care for hair damage (self-reported)
