Description

Description: TECHNICAL FIELD The present invention relates to a hair styling product used for styling hairstyles and making the set last longer.

[Conventional technology]

Hair styling products are classified into oil-based hair styling products and non-oil-based hair styling products according to their main ingredients.
Pomades, tics, hair creams and the like, and non-oil hair styling agents include set lotions, hair liquids, hair solids, hair sprays and the like. These include mainly camellia oil, southern oil, liquid paraffin, as a setting agent (hair setting agent or hair fixing agent) for fixing hair.
Fats and oils such as castor oil, or polyvinylpyrrolidone,
Synthetic resins typified by acrylic resins (for example, acrylic acid-acrylic acid ester copolymers) and other polymer materials are used.

[Problems to be Solved by the Invention]

The hair styling agent which mainly uses the above-mentioned oils and fats as a setting agent has a large setting power, and therefore, a strong setting can be performed without heat treatment, but on the other hand, it is sticky or can be washed off only with water. There is a problem that it does not exist.

On the other hand, hair styling products that mainly use synthetic resins as setting agents are
Although it is not as sticky as the one using the above-mentioned fats and oils at the time of use, curling retention is poor because the resin itself has hygroscopicity, and there is a problem of reduction in setting force and stickiness under high humidity. Further, in the hard type hair styling agent, since the content of the resin is high, the so-called flaking phenomenon which easily impairs the aesthetics of the hair due to the peeling of the resin easily occurs.

In view of such circumstances, it is an object of the present invention to provide a hair styling product which is not sticky and has a good texture, is excellent in hair fixing power (holding power), and is less likely to cause flaking.

[Means for Solving the Problems]

In order to solve the above problems, the hair styling product according to the present invention is
As a setting agent, iota type and / or K ⁺ ion content is 5% by weight or less and Ca ²⁺ ion content is 0.2
A kappa-type carrageenan of less than or equal to wt% is included, and carrageenan other than the above is substantially not included.

[Action]

The specific carrageenan used as a setting agent has low hygroscopicity and exhibits excellent hair-fixing ability with a small amount. Therefore, it can be a hair styling product having high hair fixing power, less flaking, and good texture.

In addition to iota type and kappa type, carrageenan also includes lambda type carrageenan.
However, this lambda carrageenan has a very high gelling ability and forms a gel when added to the hairdressing preparation,
It cannot function as a set agent.

The setting agent is in a dissolved state when added to the hairdressing preparation, and when the hairdressing preparation is attached to the hair during use, when a volatile component disappears, a film is formed to cover the hair, The function of fixing the hair is a component that can fulfill. Without such film-forming ability, it is not effective as a setting agent.

Since a material having a high gelling ability such as lambda carrageenan forms a gel when it is added to the hair styling product, the hair cannot be thinly covered when the hair styling product is applied to the hair.
Also, the preformed gel breaks during handling when applied to the hair. Since the broken gel cannot form a film, lambda carrageenan cannot sufficiently exhibit its function as a setting agent for fixing hair. Not only that, the presence of lambda carrageenan has the drawback of giving a sticky feel due to the thickening effect of lambda carrageenan and impairing the quality performance of the hair styling product. Among kappa carrageenan, those which do not satisfy the above-mentioned specific ion content condition also have the same problem as lambda carrageenan.

〔Example〕

 The present invention will be described in detail below.

The types of carrageenan that is a setting agent in the present invention are limited to the following. That is, carrageenan includes iota (ι) type, kappa (κ) type, and lambda (λ) type as its constituent polymer components. However, from the practical viewpoint that it is difficult to gel (solidify) and it is easy to maintain a liquid state,
^{Alternatively} , a kappa type one having a K ⁺ (potassium ion) content of 5% by weight or less and a Ca ²⁺ (calcium ion) content of 0.2% by weight or less is used. Moreover, the kappa-type carrageenan and the lambda-type carrageenan that deviate from the above-mentioned ion-containing conditions are substantially not included. Thus, the above K ⁺ , Ca ²⁺
Kappa carrageenan, which has a low content of both cations, has a low set point (solidification temperature), so it can prevent gelation even when used at high concentrations, and has a higher film-forming ability, that is, a higher settability. It is possible to prepare a strong hair styling product. Since the iota type carrageenan originally has a low gelling ability (low solidification temperature), there is no problem even if it is used at a high concentration.

The content of the carrageenan in the hairdressing composition may be appropriately set according to the type of the hairdressing composition and is not particularly limited, but it is generally preferably about 0.1 to 4% by weight. .

The form of the hair styling product according to the present invention is not particularly limited to a lotion form, a liquid form, a pomade form, a gel form, a cream form, a mousse form and the like. Ingredients other than carrageenan contained in the hair styling agent can be optionally added and adjusted depending on the form and purpose of use. Furthermore, as the setting agent, a substance other than carrageenan (normal oil, synthetic resin, etc.) may be used in combination. In addition, the viscosity of the hair styling material may be appropriately selected according to its form (for example, in the case of a lotion type hair styling material, the viscosity at 20 ° C. is 10 cP or more).

For example, in the case of a lotion-shaped hair styling agent (set lotion, etc.), a wetting agent such as glycerin, propylene glycol, higher alcohol, polyhydric alcohol ester, a plasticizer or a softening agent is mixed with carrageenan as a set agent, and these are added. It can be obtained by dissolving purified water and ethanol as a solvent or dispersing them in a colloidal form. A quick-drying lotion can be obtained by increasing the content of ethanol as the solvent.

In the case of a liquid hair styling agent (hair liquid), carrageenan may be dissolved in purified water and a solvent such as ethanol, and a wetting agent, a softening agent, etc. may be added if necessary.

The pomade hair styling material is divided into an aqueous pomade and an oily pomade as a raw material, and the latter further includes a mineral type and a vegetable type. In both cases, carrageenan as a setting agent, liquid paraffin and vaseline which are mineral oils in the case of mineral pomade, castor oil and olive oil which are vegetable oils in the case of plant pomade, and oil ( (Mineral oil or vegetable oil), purified water and a surfactant may be added respectively to prepare.

The gel-like hair styling agent is obtained by using a water-soluble polymer (synthetic resin) such as carboxyvinyl polymer, and dissolving this together with carrageenan in a solvent such as purified water to prepare a gel.

A creamy hair styling agent (hair cream) is a mixture of carrageenan with any animal or vegetable oil or mineral oil, and 30 to 70% by weight of purified water is added to this to emulsify it into a W / O type or O / W type. It is obtained by doing.

If it is a mousse-like or foam-like hair styling agent (hair mousse, hair styling foam, hair blow foam, etc.), an ordinary surfactant (nonionic type) is used in an amount of 1 wt% or less,
An aqueous base containing 0.5-1% by weight of carrageenan is filled in an aerosol can together with a liquefied propellant gas (propellant) such as CFC gas or propane-based gas, and is sprayed into a foam (mousse or foam) at the time of use. It may be prepared as follows.

Furthermore, each of the above types of hair styling products according to the present invention,
If desired, one or more kinds of optional colorants, fragrances, preservatives, antioxidants, ultraviolet absorbers, solvents other than the above may be contained.

The method of using the hair styling agent described above is not particularly limited, and for example, the hair styling agent may be attached to the hair by using a hand, a hair brush or the like to shape the hair into a desired shape.
After that, the hair is strongly set by evaporating and drying water, which is a solvent of the hair styling agent, to dry the hair. However, it is preferable to dry the hair in addition to accelerating it while adjusting the hair with a dryer or the like.

The characteristics of carrageenan as a setting agent will be described below in comparison with other setting agents.
