BACKGROUND OF THE INVENTION
The present invention relates to a shampoo, and more particularly to a shampoo with less hair squeak during and after shampooing.
[0002]
[Prior art]
In general, the role of the shampoo is to wash away secretions and dandruff attached to the scalp and hair, dirt attached from the outside, used hair styling, and the like due to the surfactant action of the surfactant.
[0003]
However, conventional shampoos have a problem that squeaks are generated in the hair after shampooing.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to solve the problems of the conventional shampoos as described above, and to provide a shampoo with less hair squeak during and after washing.
[0005]
[Means for Solving the Problems]
The present invention comprises a shampoo by combining an anionic surfactant, an acylated silk polypeptide, and linoleamidopropyl PG-dimonium chloridolinate dimethicone (Linoleamidopropyl PG-Dimonium Chloride Phosphate Dimetone), It solves the above problems.
[0006]
That is, an anionic surfactant is a main agent that exerts detergency, but an acylated silk polypeptide improves hair slip during rinsing, and linoleamidopropyl PG-dimonium chloride dimethicone is hair. Moisture is introduced into the hair to improve the softness of the hair after rinsing and after drying, thereby reducing the squeaking of the hair during and after washing.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the anionic surfactant is a main agent that exhibits detergency, and examples of the anionic surfactant include alkyl ether carboxylates, alkenyl sulfates, olefin sulfonates, alkenyls. Ether carboxylate, sulfosuccinate, unsaturated fatty acid salt, acylated taurine salt, acylated glutamate, acylated alaninate, alkyl sulfonate, alkyl sulfate, polyoxyethylene alkyl ether sulfate, acylated hydrolyzed collagen Examples of such salts include sodium salts, potassium salts, ammonium salts, and triethanolamine salts. Among them, triethanolamine salts are particularly preferable because they can improve foaming of shampoo. . And as a compounding quantity to the shampoo of this anionic surfactant, 5-18 mass% is preferable and 7-16 mass% is more preferable.
[0008]
However, as the surfactant, in addition to the anionic surfactant, an amphoteric surfactant, a nonionic surfactant, and the like may be used together with the anionic surfactant. Examples of the amphoteric surfactant include imidazoline betaine, alkyl betaine, alkylamido betaine, alkylamidopropyl betaine, and alkyldimethylamidopropyl betaine. Nonionic surfactants include, for example, alkyl polyglucoside, Examples include alkylol amide, coconut oil fatty acid alkylol amide, and coconut oil fatty acid dialkyrol amide. And as the compounding quantity of these amphoteric surfactant and nonionic surfactant, since an anionic surfactant is already mix | blended, although it does not specifically limit, amphoteric surfactant is 1-5 mass. %, The nonionic surfactant is preferably 0.1 to 3% by mass.
[0009]
As described above, the acylated silk polypeptide has an effect of improving the feeling of slipping during rinsing, but the amount of the acylated silk polypeptide is not particularly limited, but is small. If the amount is too large, the above-described effects may not be sufficiently exhibited, so 0.2% by mass or more is preferable, 0.5% by mass or more is more preferable, 0.8% by mass or more is further preferable, and when the amount is too large. Since foaming at the time of shampooing worsens and it may be difficult to increase the viscosity even in viscosity adjustment, it is preferably 2% by mass or less, more preferably 1.8% by mass or less, and further preferably 1.5% by mass or less.
[0010]
As described above, linoleamidopropyl PG-dimonium chloridolinate dimethicone has an action of improving the softness of hair after rinsing and drying by introducing moisture into the hair. -Dimethicone chloride dimethicone has the following formula:

Wherein a, b, c, m, and n are arbitrary numbers, and such linoleamidopropyl PG-dimonium chloridolinate dimethicone is manufactured by ICI Corporation from the Unichema office as “MONASIL”. What is marketed with the brand name of "PLN" can be used. In addition, if the amount of this linoleamidopropyl PG-dimonium chloridolinate dimethicone is too small, it may not be possible to sufficiently exhibit the above-mentioned action, so 0.01% by mass or more is preferable. 05 mass% or more is more preferable, 0.08 mass% or more is more preferable, and if it increases too much, the effects of cationic treatment, rinsing, conditioner, etc. after shampooing may be diminished, so 0.25 mass% or less Preferably, 0.20 mass% or less is more preferable, and 0.15 mass% or less is more preferable.
[0011]
And the shampoo of the present invention is formulated with water or an aqueous liquid containing water as a main component, the anionic surfactant, acylated silk polypeptide and linoleamidopropyl PG-dimonium chloride dimethicone as essential components, Further, if necessary, the above amphoteric surfactants, nonionic surfactants, polyols such as cationized cellulose, glycerin, propylene glycol, sorbitol, thickeners, pearlizing agents, perfumes, UV absorbers, antioxidants In addition, a chelating agent, an anti-inflammatory agent, an antiseptic and the like are appropriately blended, and these components are prepared by dissolving or dispersing them in the above water or an aqueous liquid mainly containing water.
[0012]
【Example】
Next, the present invention will be described more specifically with reference to examples. However, this invention is not limited only to those Examples. In the following examples and the like,% indicating concentration is mass%.
[0013]
