This application claims the priority of Korean Patent Application No. 10-2017-0147645 (filing date: November 7, 2017) and No. 10-2018-0123647 (filing date: October 17, 2018), for reference , the entire content of the basic application is included in this specification.

The present invention relates to a foam-type hair dye composition, in particular, it relates to the formation of softer foam and the reduction of the volume of the foam due to the inclusion of PQ-55, shea butter, and glyceryl stearate, so that it can be applied when applied A foam-type hair dye composition with improved properties and dyeing qualities.

The most typical and common method of using hair dye is to mix the first hair dye and the second oxidizing agent in the form of cream or lotion and apply it to the hair. The demand for simple dyeing methods that are easy to dye has increased, and interest in foam dyeing has gradually increased.

Foam-type hair dyes are attracting more and more attention because they can be easily dyed by themselves like shampoo, but when applied to hair and left for a long time, compared with cream-type or emulsion-type products, the content The low viscosity of the substance will cause the content to flow down, so it is also difficult to Drawbacks to achieve uniform coloring of the hair. In addition, it has low adhesion to hair, so compared with cream or lotion-type products, not only the dyeing ability and decolorization ability will be greatly reduced, but also the damage to hair will increase.

Therefore, for foam-type hair dyes, there is an urgent need to ensure the convenience of a foam-type that does not flow down the content and can be easily dyed by oneself, while ensuring better dyeing ability and decolorization ability, and reducing hair damage. to minimum.

In addition, foam-type hair dyes are roughly classified into aerosol-type and non-aerosol-type. The aerosol-type is a method in which the content is mixed with gas and the content is discharged by the pressure of the gas. Conversely, non-aerosol types do not contain gas, but instead cause the contents to pass through the mesh screen of the foaming mesh to form a foam. The aerosol hair dye that uses a propellant has the advantage of being easy to use multiple times after the content is used up, but for bleaching that needs to be used in a large amount at one time, its efficiency will be lower than the price of auxiliary materials. reduce. In addition, for aerosol hair dyes, since the foam is discharged with a strong spray pressure, resulting in low foam density, the concentration of the dye delivered to the hair is relatively reduced compared with the conventional cream type or emulsion type, thereby having the advantages of The problem of reduced hair dyeing ability.

In conventional foam-type hair dyes, it is intended to improve the elasticity of the foam by using anionic surfactants with excellent foam-forming ability or utilizing a large amount of zwitterionic surfactants and polymer thickeners. However, when anionic surfactants are used, further irritation is caused or the dyeing ability is reduced, and when a large amount of zwitterionic surfactants are used, the dyeing ability is significantly lowered than when anionic surfactants are used. In addition, polymer thickeners can make the foam more viscous immediately after being discharged, but when left for a long time after being applied to the hair, the foam tends to defoam, so there is a problem that the content tends to flow down.

In addition, cationic polymers that greatly affect the hair conditioning feel are difficult to contain in large amounts in the first or second agent from the viewpoint of the stability of the content, and depending on the type of use, the hair conditioning effect may be different. showed a large difference.

In addition, there are cases where a defoamer including oil is used to increase the foam density, but even if a small amount of this substance is used, the discharged foam will disappear sharply, or the foam will not be discharged smoothly, so it will reduce the foam density. Ease of use.

Therefore, in order to obtain a foam dosage form with the required properties, it is very important to select and mix appropriate raw materials.

In particular, the foam-type oxidation hair dye composition of the present invention is characterized in that it is an aerosol type.

Polyquaternium-55 (Polyquaternium-55; PQ-55) used in the present invention is the quaternary ammonium salt compound that belongs to cationic surfactant, relative to the gross weight of the first agent or the second agent composition (that is, Based on the weight of the formulation containing PQ-55), the hair dye composition of the present invention contains 0.1 to 5% by weight of PQ-55. When the content of PQ-55 is less than 0.1% by weight, it is difficult to expect the desired effect, and when the content of PQ-55 exceeds 5% by weight, the sticky feeling in use may lead to a decrease in spreadability.

The low-melting-point lipids used in the present invention refer to lipids with a melting point of 40°C or lower.

In addition, components generally used for hair dyes can be used in the oxidation hair dye composition of the present invention within the range that does not reduce the effect of the present invention. For example, antioxidants, chelating agents, solvents, surfactants, thickeners, fragrances, conditioners and the like can be used, but these are components generally used in hair dyes and are not particularly limited.

Chelating agents reduce the reactivity of metal salts and therefore should not be included in the compositions of the present invention, or should be included only in minimal amounts. Examples of the chelating agent include ethylenediaminetetraacetic acid (EDTA), disodium edetate, tetrasodium edetate, pentasodium pentetate, etidronic acid, and salts thereof.

And anionic polymers, paraffin, light liquid isoparaffins, etc., cationic polymers, quaternary ammonium salts or silicon can be used as conditioners.

Next, the components of the second part of the oxidation hair dye composition of the present invention will be described.

The second agent contains an oxidizing agent, and the oxidizing agent can be selected from hydrogen peroxide, carbamide peroxide, alkali metal bromate, ferricyanide, perborate and persulfate commonly used in oxidative hair dye compositions. One or more of them, especially hydrogen peroxide is preferably used.

Relative to the total weight of the composition, the propellant is used in an amount of 5-10% by weight. The reason is that when the amount of the propellant used is less than 5% by weight, the injection pressure is low, resulting in the failure to normally discharge the contents from the container, and when the amount of the propellant used exceeds 10% by weight, the injection state changes. Poor, and the gas pressure is high, so it is difficult to develop into a desired form, that is, it is difficult to develop into a mousse type dosage form with rich foam.

The hair dye composition of the present invention is used by mixing the first part and the second part before applying it to the hair. At this time, although not particularly limited, it is preferable to mix and use the first agent and the second agent in a weight ratio of 1:1 to 1:2.

When mixing, if the ratio of the first agent is reduced, the amount of the dye will become less, resulting in less dye penetrating into the hair, thereby reducing the color development ability, and if the ratio of the second agent is increased, the reaction speed will be sharp Increase, so that an addition reaction will occur, if the proportion of the second agent decreases, the reaction rate will slow down.

In addition, the method of dyeing hair using the hair dye composition of the present invention may include the following conventional hair dyeing methods, that is, mixing the first agent and the second agent to prepare an oxidative hair dye, and applying the oxidative hair dye Apply to hair and wash after the specified time.
