Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to shampoo compositions, and particularly to shampoo compositions that have both hair-nourishing and conditioning effects. [Prior Art] Conventionally, hair cosmetics such as hair nourishing agents have been blended with various medicinal agents that are expected to have hair nourishing and hair growing effects. Medicinal agents include vitamins such as vitamin E, amino acids such as serine and methionine, vasodilators such as acetylcholine derivatives, anti-inflammatory agents such as purple root extract, female hormones such as estradiol, and skin function enhancers such as cephalanthine. It is used to prevent and treat alopecia. Examples of hair cosmetics containing fatty acids or derivatives thereof include those containing natural vegetable oils such as olive oil and castor oil or stearic acid for the purpose of improving the physical properties of the product. but,
Almost all of these are fatty acids with even carbon chain length. Therefore, in the conventional commercially available products, there is no example in which a fatty acid having an odd number of carbon atoms or a derivative thereof is incorporated into a hair cosmetic for the purpose of hair nourishment or hair growth. Furthermore, regarding the higher alcohols used in hair cosmetics such as hair rinses, all commercially available alcohols or derivatives thereof have even-numbered chain length carbons, and odd-numbered chain length alcohols are used as hair growth ingredients. There are no examples of it being used as such. According to JP-A No. 59-27809, fatty acids with odd chain lengths or their derivatives have been found to have a hair growth effect, unlike those with even chain lengths, and fatty acids with odd chain lengths or their derivatives have been found to be effective. Ingredients and shampoo compositions were proposed. [Problems with the prior art] However, such shampoo compositions
It has the disadvantage that it leaves a squeaky feel, commonly referred to as "squeak", after washing, washing, and rinsing the hair, and that combing (combing or brushing) is poor when the hair is half-dried after being towel-dried. Furthermore, when the hair is completely dry, it has poor manageability and combability, and static electricity is likely to be generated when brushing during periods of low humidity. It has the disadvantage that it gets worse. [Object of the invention] The object of the invention is to eliminate the "squeak" when washing and rinsing the hair, to give the hair a moist, soft feel and good combability without using a hair rinse agent, and to improve the dryness. To provide a shampoo composition which prevents the hair fly phenomenon that sometimes occurs, has a conditioning effect that allows easy hair styling, and also has an excellent hair-nourishing effect. [Summary of the Invention] That is, the present invention provides (a) an anionic surfactant or an amphoteric surfactant of 3 to 40% by weight, and (b) a cationic surfactant with a cationization density of 0.0005 to 40% by weight.
0.005% by weight of a quaternary nitrogen-containing water-soluble polymer, (c) odd-numbered chain length higher fatty acids or odd-numbered chain length higher fatty acid alcohols, or derivatives thereof.
A shampoo composition containing 0.1 to 10% by weight is provided. [Effects of the Invention] The shampoo composition of the present invention can exhibit excellent hair conditioning properties and excellent hair growth effects in addition to cleansing properties, which are the basic performance of shampoos. In other words, when used to clean hair, etc., it exhibits high foaming properties and moderate cleaning power,
When rinsing, "squeak" is suppressed, and when finishing the hair, the hair becomes easier to tame, is not sticky, has a supple and moist finish, and has good combability. Furthermore, it prevents hair fries when drying. In addition, odd-number chain length higher fatty acids or odd-number chain length higher aliphatic alcohols or derivatives thereof penetrate the hair roots better than the scalp,
Demonstrates excellent hair growth effect. [Detailed Description of the Invention] The first essential component of the composition of this invention is an anionic surfactant or an amphoteric surfactant. Two or more of these may be used in combination within the same range. The anionic surfactant may be any one commonly used in shampoos. Specific examples are listed below. Alkali metal salt or alkanolamine salt of lauric acid; natural lauryl alcohol 3 mole ethoxysulfate, oxo method synthesized carbon 12-16 aliphatic alcohol 3 mole ethoxysulfate, oxo method synthesized carbon 12-16 aliphatic alcohol 1 mole ethoxysulfate Or alkali metal salts, alkaline earth metal salts or alkanolamine salts of esters such as sulfuric esters of aliphatic alcohols having 12 to 16 carbon atoms; obtained by wax slugging method, polymerization method using Ziegler catalyst, or modified methods thereof. Alphaolefin with 12 to 14 carbon atoms, 12 to 14 carbon atoms
Alkali metal salt, alkaline earth metal salt, or alkanolamine salt of anionic surfactant obtained by sulfonating 16 vinylidene olefin and inner olefin having 12 to 16 carbon atoms with sulfur trioxide, etc., and further hydrolyzing;, carbon number 12 -14 Acylamide polyglycol ether (3-8 mol) alkali metal salt, alkaline earth metal salt or alkanolamine salt of sulfuric acid ester. The amphoteric surfactant may also be any of those commonly used in shampoos. Specific examples are listed below.

If the amount is less than 3% by weight, satisfactory cleaning power and foaming performance will not be obtained, and if it exceeds 40% by weight, the liquid stability will be impaired and if stored in a cold environment, it may become cloudy or separate. occurs. The second essential component of this invention is a cationic surfactant or a quaternary nitrogen-containing water-soluble polymer with a cationization density of 0.0005 to 0.005. The cationic surfactant and the nitrogen-containing water-soluble polymer may be used in combination of two or more types within the same category.
