Abstract

PURPOSE:To provide a hair dressing agent containing carrageenan as a setting agent, having excellent hair-fixing power (holding power) and good feeling, free from tackiness and resistant to flaking. CONSTITUTION:The objective hair-dressing agent contains about 0.1-4wt.% of a carrageenan having low hygroscopicity and exhibiting excellent hair-fixing power in a small amount. The carrageenan is preferably kappa(kappa)-type carrageenan having a K<+>-content of <=5wt.% and a Ca<2+>-content of <=0.2wt.% and/or iota(iota)-type carageenan.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a hair styling product used for styling hair and making it last longer.

[Conventional technology]

Hair styling products are classified into oil-based hair styling products and non-oil-based hair styling products, depending on their main ingredients. Oil-based hair styling products include hair oil,
Pomades, ticks, hair creams, etc. are used as non-oily hair products such as send lotion.

There are hair liquids, hair solids, hair sprays, etc.

These mainly include oils and fats such as camellia oil, sasanquat oil, liquid paraffin, and castor oil, as well as polyvinylpyrrolidone and acrylic resins (hair centrants or hair fixing agents) that fix the hair. For example, synthetic resins such as acrylic acid-acrylic acid ester copolymers and other polymeric materials are used.

[Problem to be solved by the invention]

Hair styling products that mainly use the above oils and fats as cent agents have a large sesotonka, so they can be set firmly without heat treatment, but on the other hand, they are sticky and cannot be washed off with water alone. There is a problem that

On the other hand, hair styling products that mainly use synthetic resin as a cent agent are
When used, it does not become as sticky as those using the above-mentioned oils and fats, but since the resin itself has hygroscopic properties, curl retention is poor, and there are problems with a decrease in sesotonka and stickiness under high humidity. Furthermore, since hard type hair styling products have a high resin content, the so-called flaking phenomenon, which impairs the beauty of the hair due to peeling of the resin, is likely to occur.

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

[Means to solve the problem]

In order to solve the above problems, the hair styling product according to the present invention includes:
Contain carrageenan as a cent agent.

[For production]

Carrageenan, which is used as a cent agent, has low hygroscopicity and exhibits excellent hair fixing ability even in small amounts. Therefore, it is possible to obtain a hair styling product with high hair fixing power, less flaking, and a good texture.

〔Example〕

The present invention will be explained in detail below.

The type of carrageenan used as the cent agent in this invention is not particularly limited, and its constituent polymer components may be of the iota (t) type, campa (ni) type, or lambda (λ) type. A mixture of these materials in any proportion may be used. However, from the practical point of view that it is difficult to gel (solidify) and is easy to maintain a liquid state, Iota type and/or K" (potassium ion)
It is preferable to use a camphor type material having a content of 5% by weight or less and a content of Ca (calcium ions) of 0.2% by weight or less. In this way, the above K”
, Ca” Campa carrageenan with a low content of thione has a low cent point (solidification temperature), so
Even when used at a high concentration, gelation can be prevented, making it possible to prepare a hair styling product with a higher film-forming ability, that is, a stronger sesotoka. Note that since iota type carrageenan originally has low gelling ability (low solidification temperature), there is no problem even if it is used at a high concentration.

The content of the above-mentioned carrageenan in the hair styling product may be appropriately set depending on the type of the hair styling product, and is not particularly limited, but - numerically, it is about 0.1 to 4% by weight. It is preferable.

The form of the hair styling product according to the present invention is not particularly limited, and may include lotion, liquid, pomade, gel, cream, mousse, and the like.

Regarding ingredients other than carrageenan contained in hair conditioners,
They can be added and adjusted as desired depending on the form and purpose of use. Furthermore, as a setting agent, something other than carrageenan (normal fat 1 synthetic resin, etc.) may be used in combination. Further, the viscosity of the hair styling product may be appropriately selected depending on its form to a value that makes it easy to condition the hair (for example, a lotion type hair styling product has a viscosity of 1OcP or more at 20°C).

For example, in the case of lotion-like hair conditioners (setting lotions, etc.), humectants, plasticizers, or softeners such as glycerin, propylene glycol, higher alcohols, and polyhydric alcohol esters are blended with carrageenan, which is a cent agent. It can be obtained by dissolving it in purified water and ethanol as a solvent or by dispersing it in colloidal form.

By increasing the content of ethanol as the solvent, a quick-drying lotion can be obtained.

If it is a liquid hair conditioner, carrageenan may be dissolved in purified water and a solvent such as ethanol, and a humectant, softener, etc. may be added as necessary.

Pomade-like hair preparations are divided into water-based pomades and oil-based pomades, and the latter include mineral-based and vegetable-based pomades. In both cases, carrageenan as a centrifugal agent is used, mineral oils such as liquid paraffin and petrolatum are used for mineral pomades, vegetable oils such as castor oil and olive oil are used for vegetable pomades, and oil (oil) is used for water-based pomades. It may be prepared by adding mineral oil or vegetable oil), purified water, and a surfactant, respectively.

A gel-like hair conditioner is obtained by using a water-soluble polymer (synthetic resin) such as a carboxyvinyl polymer and dissolving it together with carrageenan in a solvent such as purified water to prepare a gel-like product.

Cream-like hair conditioners (hair creams) are made by blending carrageenan with any animal or vegetable oil or mineral oil.
It can be obtained by adding about % by weight of purified water and emulsifying it into W2C type or O/W type.

For mousse-like or foam-like hair styling products (hair mousse, hair styling foam, hair profume, etc.), 1% by weight or less of ordinary surfactants (nonionic),
An aqueous-based product containing 0.5 to 1% by weight of carrageenan is filled into an aerosol can with a liquefied propellant gas (propellant) such as chlorofluorocarbon gas or propane gas, and is turned into a foam (mousse or foam) when used. It can be prepared so that it can be sprayed.

Furthermore, each of the above types of hair styling products according to the present invention includes:
If necessary, one or more of arbitrary colorants, fragrances, preservatives, antioxidants, ultraviolet absorbers, and solvents other than those mentioned above may be included.

The method of using the above-mentioned hair styling product is not particularly limited either, but for example, the hair styling product may be applied to the hair using hands or a hair brush, and the hair may be shaped into a desired shape.

Thereafter, water, which is a solvent of the hair styling product, evaporates and dries, thereby firmly setting the hair. In addition to drying naturally, it is also preferable to accelerate drying while conditioning the hair with a hair dryer or the like.

Below, the characteristics of carrageenan as a hexasol agent will be explained in comparison with other cent agents.
