Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an aerosol hair removal agent, and more particularly to a quick-drying aerosol hair removal agent that causes very little pain during hair removal (also has very little skin irritation or side effects).

[Conventional technology]

Conventionally, wax-type, adhesive-type, and adhesive-type hair removal agents are known as hair removal agents used by women to remove unwanted hair from their arms and legs.

Aerosol type hair removal agents are not in practical use. [Problem that the invention seeks to solve] Conventionally known wax type and adhesive type.

No matter which adhesive type hair remover is used, each hair is forcibly pulled and removed, which can cause pain and, in some cases, inflammation. Also, wax type hair removers require waxing at a high temperature before use. Must be used after melting 1
It has the disadvantage of poor workability.

In this way, conventional hair removal agents have poor workability (and can cause irritation to the skin and side effects during hair removal). The problem was devising a drug.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present inventor 0 and others conducted various studies, and in particular examined various aerosol-type hair removal agents, and found that low boiling point solvents and liquefied gases cause very little irritation and side effects to the skin. The discovery that liquefied gas gives a cold sensation to the skin (and has the effect of temporarily paralyzing the nerves) led to the creation of the present invention.

In other words, the present invention is a resin! ~30 parts, plasticizer θ, 7~]
θ part, 40 parts of a low-boiling bath agent, and 20 to 73 parts of liquefied gas as a propellant, or these and an appropriate amount of pigment or dye, each with a total amount of 100 parts. This is an aerosol hair removal agent in which an aerosol container is filled with a resin, a plasticizer, a low-boiling solvent, and a liquefied gas as a propellant, and if necessary, a pigment or dye, and is equipped with an aerosol valve and a button. The present invention will be explained in detail.As the resin used in the present invention, any resin can be used as long as it is effective for forming a resin film.
Preferred specific examples include butyral resin, acrylic resin, styrene resin, etc. These resins may be used alone or in a mixture of two or more. Ha coooo.

It can be put to practical use by selecting θθθ0θ).

Next, as the plasticizer, any plasticizer can be used as long as it imparts plasticity to the resin coating to be formed.Normally 1Plasticizers listed in the Food Additives Official Standards or Cosmetic Raw Materials Standards are used. Specific examples of preferred plasticizers include, but are not limited to, lipophilic nonionic surfactants (eg, sorbitan fatty acid esters, glycerin fatty acid esters), phthalic acid diesters.

Alternatively, a mixture selected from these may be used.These plasticizers have almost no irritation to the skin.Next, as a low boiling point solvent, the boiling point is about 0°C to ♂0°C and is not toxic to the skin. A semi-nonflammable material with little irritation is suitable.A specific example of this is nonflammable trichloromonofluoromethane C or less.

Fil), trichlorotrifluoroethane (hereinafter referred to as Fll3), or a semi-nonflammable mixture selected from Fil, Fll3, and alcohol.

Although it is flammable, it can be used by considering the amount used or by mixing it with nonflammable Fll, Fll3, etc.

Pentane, hexane, etc. can also be used, mainly acting as propellants (liquefied gases include dichlorodifluoromethane C and below, written as F12), and monochlorodifluoromethane C and below.

F22) or F12%F22. Dichlorotetrafluoroethane (hereinafter referred to as Fll4), monochlorodifluoroethane (hereinafter referred to as F142b),
A preferred example is a mixed liquefied gas selected from dimethyl ether and liquefied petroleum gas.0F12. Nonflammable liquefied gases such as F22 can be used alone, but flammable gases such as dimethyl ether and liquefied petroleum gas must be used within a range that maintains nonflammability to slightly flammability (flame length as specified in Ministry of International Trade and Industry Notice No. 7). is less than 2 J-σ, and the explosive concentration is 0,2 j f / A or more].
θ: 3θ Liquefied petroleum gas can be used (up to the weight)
This is aimed at the effect of cooling the affected area using the heat of vaporization. The same thing can be said about aerosol hair removal products.
F12 with a low boiling point. When you apply F21 Prono-kun, etc., it numbs the area where you want to remove hair by cooling the area.

It is desirable to use a large amount of these liquefied gases.In addition, liquefied gases should be used so that the internal pressure of the aerosol hair removal product is below the ♂'j'/crl specified by law in Jj'C. 0 Furthermore, in order to make the resin film formed using the aerosol hair removal agent of the present invention look more beautiful, the present invention uses pigments,
O The aerosol depilatory agent of the present invention can also contain an appropriate amount of dye etc. The above-mentioned resin.

A plasticizer, a low-boiling solvent, and a liquefied gas as a propellant, and if necessary, a pigment or dye are added to the resin mixture.
゛0.1% IQ part of plasticizer, t-go part of low boiling point solvent, and liquefied gas θ~7 as propellant! or an appropriate amount of pigment or dye, which is filled into an aerosol container so that the total amount of each is 700 parts, and is manufactured by attaching aerosol pulp and buttons. In this case, by appropriately selecting a low boiling point solvent and a liquefied gas as a propellant, it is possible to obtain an aerosol depilatory agent that is quick drying and has a slightly flammable or better rating. Furthermore, filling the aerosol container, attaching the aerosol pulp and buttons, etc., can be carried out according to conventional methods for manufacturing aerosol products.

When manufacturing the aerosol hair removal agent of the present invention, the resin! If the amount is less than 3 θ parts, the formed resin film will become stiff and the workability will be poor. If the resin exceeds 3 θ parts, it will dry too quickly and will not adhere to the skin and the hair removal effect will be lost. Therefore, it is appropriate to use 5 to 30 parts of resin.
Also. Plasticizer is 0. If the amount is less than 1 part, the plasticity of the formed resin film will decrease, and if it is more than 10 parts, the plasticity will increase and the hair removal effect may be impaired.
% 10 parts is appropriate. Low boiling point solvent!
If it is below 100 ml, it dries too quickly and does not adhere to the skin (
(If the amount of low boiling point solvent exceeds 60 parts, the hair removal effect will decrease.)

Avoid using low-boiling point solvents as the applied aerosol contents may flow or run quickly on the skin, making workability difficult.
It is appropriate to make it a department. In addition, if there is little liquefied gas as a propellant, the injection performance may be insufficient, and if there is a large amount of liquefied gas with a low boiling point, the pressure will be high (3J at °C/[
(P/dr or less) may occur, and liquefied gas may exceed 20~20 liters! It is appropriate to make it a department.

Next, the use of the aerosol hair removal agent of the present invention and the mechanism of hair removal will be described.

Press the button of the aerosol hair removal agent of the present invention to remove hair from the hair removal area (
If you apply this hair removal product to the hair removal area, the heat of vaporization of the liquefied gas will cool and numb the hair removal area and numb it. A resin film is formed, and the hair is trapped in an upright shape within this resin film.The vaporized liquefied gas is much heavier than air, so the hair removal area is continuously cooled and numbed.About 1 minute After that, when the resin film that has become a wind-flap shape is crushed, the liquefied gas that has vaporized at the same time flies away, and most of the hairs that were in an upright shape are pushed from above, resulting in a pack that has crushed the wind-flap-shaped resin film. Leave it for about 1 minute until the stickiness disappears, and then peel off the resin film that has formed in the shape of a bag.It is removed from the root of each hair, so it is less painful (hair removal can be done).
