Description

The object of the present invention is to give shine to hair after shampooing.

In recent years, people have come to enjoy hairstyles and hair colors as part of fashion, and hair coloring and perming have become commonplace. Hair is damaged by hair coloring, perms, etc., and the texture of the hair becomes dry, making it difficult to maintain the overall hair surface and making it look less shiny.

In addition, if the hair is damaged, it may become tangled during shampooing, it may not be easy to run through your fingers when rinsing, and the hair may become tangled, causing the hair to appear less shiny. Therefore, there is a need for a method to improve the shine of hair.

It is known that methods of giving shine to hair include leaving an appropriate amount of oil on the hair surface and conditioning the hair surface to suppress diffused reflection of light. Silicone is also generally known as its component. For this reason, oil-based ingredients such as silicone are often blended into shampoo and conditioner formulations that provide a glossy finish.

A composition is known in which a silicone is blended into an aqueous detergent to give gloss, manageability, and smoothness to the finished hair (Patent Document 1). By using an aqueous cleanser that contains silicone, the silicone remains on the hair after washing, giving the hair smoothness and shine.

Furthermore, in order to give shine to hair, a component obtained by hydrolyzing protein such as collagen is known as a component for repairing the hair surface (Patent Document 2). It has been reported that by incorporating these ingredients into shampoo/conditioner formulations, hair damage can be prevented, damaged hair can be repaired, and hair and skin can be moisturized.

However, in recent years, it has become known that silicone contained in shampoos remains near the pores, and an increasing number of consumers are concerned about their pores becoming clogged. Therefore, consumers have begun to demand non-silicone shampoo formulations.

Embodiments of the present invention will be described below.

In the present invention, the gloss of hair refers to the glossy state of the hair after washing the hair with a shampoo composition and drying it with a towel dryer.

<(A) Myristic acid PPG-3 benzyl ether>
(A) blended in the present invention is myristic acid PPG-3 benzyl ether. Component (A) is an ester oil obtained by alkoxylating an aromatic alcohol called benzyl alcohol, and is a petroleum-derived synthetic polymer used as an emollient. It is known to be included in shampoo compositions as a substitute for silicone, and has the effect of retaining moisture and making it moist.

Further, in the present invention, since the component has a high refractive index, it has the effect of imparting luster and shine to the hair.

In the present invention, the blending amount of (A) is preferably 0.02 to 2% by weight based on the total weight of the shampoo composition. If it is 0.02% by mass or more, the hair will have good shine, and if it is 2% by mass or less, it will give a suitable oily feel to the hair and give good shine.

<(B) Protein hydrolyzate>
(B) blended in the present invention is a protein hydrolyzate. Specific examples include hydrolyzed collagen, hydrolyzed silk, hydrolyzed conchiolin, and hydrolyzed keratin. This component is known to replenish moisture to damaged hair because it has a certain water absorbency and permeability to the hair.

In addition, in the present invention, component (B) adsorbs to the cuticle on the hair surface and repairs the hair surface, so the cuticle surface of each hair is adjusted and the surface of the hair is adjusted, which allows for light reflection. It can make your hair stronger and give it shine.

In the present invention, the blending amount of (B) is preferably 0.005 to 0.5% by weight based on the total weight of the shampoo composition. If it is 0.005% by mass or more, the hair will have good shine, and if it is 0.5% by mass or less, the odor peculiar to protein hydrolyzate can be suppressed, and the shampoo composition will have a good fragrance.

The protein hydrolyzate is not particularly limited, but hydrolyzed silk and hydrolyzed conchiolin are preferred. In the hair gloss enhancer or shampoo composition of the present invention, the component (B) may be used alone or in combination of two or more.

In the present invention, by combining (A) and (B), the gloss of the hair is synergistically enhanced by the effect of coating the hair surface and the effect of repairing and conditioning the hair surface.

<(C) Vegetable oil>
(C) blended into the shampoo composition of the present invention is a vegetable oil. Vegetable oils are oils obtained by extracting, pressing, and refining the parts of plants such as fruits, seeds, and flowers. Examples of vegetable oils include, but are not limited to, acai fruit oil, rice bran oil, camellia oil, rice germ oil, jojoba oil, tea seed oil, sunflower seed oil, apricot kernel oil, and the like.

Since component (C) is an oily component derived from plants, it imparts an emollient effect to the hair and suppresses water evaporation from the hair, thereby further improving the moist feeling after rinsing. In addition, since component (C) has a fatliquoring effect, it can reduce the feeling of squeaking when washing hair.

The blending amount of component (C) is not particularly limited, but is preferably 0.01 to 1.0% by mass based on the entire shampoo composition. If it is 0.01% by mass or more, the moist feeling after rinsing will be good, and if it is 1.0% by mass or less, it will not give a greasy feeling when used. In addition, since component (C) is extracted, pressed, and purified from plants, it has an unsaturated bond in the fatty acid site, so if it is added in an amount greater than 1%, the shampoo composition may change over time. The smell of things changes.

In the shampoo composition of the present invention, component (C) may be used alone or in combination of two or more. Preferably, this component is acai palm fruit oil.

The mass ratio of (C) and (A) ((C)/(A)) is preferably 0.05 to 1. If it is 0.05 or more, the moist feeling after rinsing will be good, and if it is 1 or less, the hair will have a good glossy feeling after drying.

<(D) Amino acid-based anionic surfactant>
(D) blended into the shampoo composition of the present invention is an amino acid-based anionic surfactant. Component (D) is an anionic surfactant consisting of an acyl group (fatty acid residue) and an amino acid (glutamic acid, aspartic acid, glycine, alanine, etc.). Component (D) has the ability to wash away oil and is a component that cleans dirt and sebum from the scalp and hair.

In the shampoo composition of the present invention, a complex called coacervate can be formed by combining the component (D) with the cationic polymer (E) described below. This coacervate adheres to the hair during hair washing, making it possible to reduce the feeling of staining. Note that the amino acid surfactant used in the present invention is capable of forming a larger amount of coacervate than a sulfuric acid surfactant.

Component (D) is not particularly limited, but it is preferable to use lauroyl sarcosine TEA, lauroyl methylalanine Na, cocoyl glutamate TEA, and cocoyl methyl taurine Na from the viewpoint of giving a feeling of reducing squeakyness during hair washing. .

In the shampoo composition of the present invention, the component (D) may be used alone or in combination of two or more in the detergent composition of the present invention. good.

The amount of component (D) to be blended is not particularly limited, but is preferably 5 to 20% by weight based on the entire shampoo composition. When the amount is 5% by mass or more, sufficient foam can be formed to exhibit cleaning performance, and the hair will not feel squeaky when washing. If it is 20% by mass or less, the detergency (degreasing ability) will not be too high and the moist feeling after rinsing will be good.

<(E) Cationic polymer>
Component (E) blended into the shampoo composition of the present invention is a cationic polymer. Ingredient (E) has a hydrophilic group that becomes a cation (positive) ion when dissolved in water, and is known to be easily adsorbed to hair, and has the effect of improving foaming properties and foam sustainability. have

In the present invention, as described above, when used in combination with component (D), a coacervate complex can be formed, and is added to provide a feeling of reducing squeakyness during hair washing.

Component (E) includes, but is not particularly limited to, polyquaternium-7, polyquaternium-10, polyquaternium-49, guar hydroxypropyltrimonium chloride, and the like.

In the shampoo composition of the present invention, the component (E) may be used alone or in combination of two or more in the detergent composition of the present invention. good.

Although the amount of component (E) is not particularly limited, it is preferably 0.1 to 0.7% by mass based on the entire shampoo composition. If it is 0.1% by mass or more, it is possible to reduce the squeaky feeling when washing hair, and if it is 0.7% by mass or less, the feeling of feeling like greasiness does not occur and the feeling of reducing squeakyness is reduced. Never.

It has been found that in the shampoo composition of the present invention, by further adding component (C) to components (D) and (E), the squeaky feeling during hair washing can be dramatically improved. This is presumed to be due to the synergistic effect of the fatliquing effect of component (C) and the coacervate forming action of components (D) and (E).

It has been found that the shine of hair can be dramatically improved by further combining components (C), (D), and (E) with the hair gloss enhancer consisting of (A) and (B) of the present invention. This is presumed to be due to the effect of the formed coacervate adsorbing and remaining on the hair, promoting the retention of component (A) and the adsorption of component (B).
