Description

Hair spray of airsol type

The present invention relates to an aerosol type hairspray composition and an aerosol valve. More specifically, the present invention relates to an aerosol type hairspray composition comprising n-butane, iso-butane or a mixture thereof as a propellant, and an aerosol comprising a mixture of n-butane and dimethyl ether (DME) as a propellant. It relates to an aerosol valve in which the structure of the hairspray composition of the type and the orifice are modified.

Humans have a desire to keep their hair in various forms. In order to satisfy this desire, permanent and temporary deformation of the hair has been attempted. Permanent deformation of the hair is achieved by using chemical raw materials that react with the hair to achieve the desired effect. The temporary setting applied to the hair as a temporary deformation of the hair is a temporary arrangement that can be returned by water or by trituration. Resin or rubber is used as a material for such setting. Temporary setting forms have been achieved using aerosol or pump type hairsprays, which are applied by the user to the hair.

Conventional hairsprays in use today generally employ non-aqueous polymers, solvents, additives and propellants [Ref. Franz Frosh., "History and Future Development of European Hair Spray Polymers" Cosmetics Toiletries, Vol 108 (May, 1993) 69-70].

Propellants used in aerosol hairsprays are usually used by mixing a liquefied gas, that is, n-butane, iso-butane, propane and dimethyl ether in a constant ratio. A conventional aerosol type hairspray manufacturing method dissolves the contents except the propellant uniformly, puts them in an aerosol container, inserts a valve, and then crimps. The desired amount of propellant is then introduced through the valve into the closed aerosol hairspray container. The liquefied gas, which is a propellant, functions as a propellant and a solvent while being present in a liquid phase in a closed container.

However, when the conventional hairspray is applied only to the desired hair part and styling the hair, the spraying force is so strong that the contents are buried up to the scalp, so the feeling was not good. In addition, when evenly spraying the entire hair, the spraying force is strong, the spray length is long, so that the contents on the clothes or face, and the amount applied to the hair is less, the set force (set hold) fell. In addition, the conventional products have a strong blowing force, so that the fine particles are blown off, so the nose is likely to be inhaled and a lot of injection odor gave a sense of rejection to the user. In addition, there is a risk of explosion due to high injection pressure in high temperature conditions, such as summer, due to the characteristic of the liquefied gas that the vapor pressure increases almost proportionally with increasing temperature.

The purpose of the present invention is to provide a soft coating feeling and excellent setting power when spraying the hair is weak, so as not to be attached to the scalp, face or clothes to provide a fresh feeling and to minimize the blowing odor due to the small particle blowing, low spray pressure, high temperature in summer It is to provide a hair spray that can increase the safety of storage.

The aerosol-type hairspray composition according to the present invention comprises 5 to 60% by weight of n-butane, iso-butane, dimethyl ether or a mixture thereof as a propellant and a polymer as a balance and the content of n-butane is 10% by weight. It is characterized by more than%.

Hair spray according to the present invention comprises aerosol type hairspray composition containing 5 to 60% by weight of n-butane, iso-butane, dimethyl ether or a mixture thereof as a propellant and the content of n-butane is 10% by weight or more. That a button orifice diameter of 0.010 to 0.040 inch, stem orifice diameter of 0.010 to 0.040 inch, vapor step orifice diameter of 0 to 0.040 inch or less, and a container having an aerosol valve having a body orifice diameter of 0.010 to 0.040 inch It features.

Hereinafter, specific embodiments of the present invention will be described in detail.

The inventors have found that the reason why the conventional products have a strong injection force is due to the orifice structure of propane and valve in the propellant.

Thus, the aerosol type hairspray composition according to the present invention comprises 5 to 60% by weight of the n-butane, iso-butane or mixtures thereof as the propellant and the polymer as the balance. The content of n-butane is 10% by weight or more.

The aerosol valve according to the invention has a button orifice diameter of 0.010 to 0.040 inches, a stem orifice diameter of 0.010 to 0.040 inches, a vapor step orifice diameter of 0 to 0.040 inches or less, and a body orifice diameter of 0.010 to 0.040 inches.

Valves used in aerosol products for high pressure gas have four or more parts combined, and each of these parts has various sizes of orifices. The spray pattern has a variety of shapes depending on which size orifice size of each component of the valve is selected. If the orifice is selected incorrectly, the valve may be clogged by the setting agent during use, or there may be a serious defect that leaves the contents at the end of use. Thus, the aerosol valve of the above structure is used to invent a system having an excellent injection pattern without clogging in the valve.

The use of 35% by weight of n-butane alone significantly lowers the blowing force than conventional products. On the other hand, reducing the content of n-butane to 10% by weight or less and applying a valve without a vapor tap orifice may further weaken the injection force. However, lowering the content by using n-butane propellant alone can make the spraying power very weak.However, when spraying the hairspray on the hair, the spraying drops to the face due to the drop phenomenon. You will have problems.

In addition, adjusting the size of the valve orifices while using iso-butane results in a slightly higher injection pressure than the above invention, but a weak injection force and an excellent injection pattern. That is, at least 10% by weight of n-butane and 30% by weight of iso-butane. Mixing up to% or each, and adjusting the size of the four types of orifices in the structure of the valve, the spraying force is very weak and can provide an excellent spraying pattern even at low temperatures.

The inventors have found that in the process of developing a spray having a weak spraying force, the spray is sprayed smoothly by applying another spray composition ratio and a suitable valve.

The aerosol type hairspray composition according to the present invention comprises 5 to 60% by weight of a mixture of n-butane and dimethyl ether as propellant and a polymer as the balance. The content of n-butane is 10% by weight or more.

The inventors have found that the dimethyl ether composition has different properties from other liquefied gases, namely n-butane, iso-butane and propane, while trying to provide an excellent spray pattern at low temperatures while significantly lowering the injection pressure. . In other words, n-butane, iso-butane and propane have a small increase in injection pressure as the content increases in the container, while dimethyl ether not only has good solubility with the contents but also increases rapidly as the content increases. . In other words, it was found that, when the appropriate amount of dimethyl ether is used, the solubility with the contents is very good without the injection pressure being high, so that an excellent spray pattern can be obtained even at low temperatures.

Therefore, a mixture of n-butane at least 10% by weight and dimethyl ether at 30% by weight is used, and a valve without vapor tap orifice is applied to provide an aerosol-type hairspray composition having a low spraying force and a very excellent spraying pattern even at low temperatures. Could. This feature provides the effect of increasing the setting force, which is the main function of the aerosol-type hairspray, since the spray particles do not fall on the clothes or the face and most of them are evenly applied to the hair.

In addition to the above propellants, the aerosol-type hairspray composition according to the present invention can be used a hair setting polymer used in the aerosol-type hairspray composition, specifically, an octylacrylamide acrylate butylaminoethyl methacrylate copolymer. In addition, additives, pH adjusters, fragrances, sunscreens, and solvents such as water or ethanol may also be included which provide moisturizing and conditioning effects.

The hairspray according to the present invention comprises 5 to 60% by weight of n-butane, iso-butane or a mixture thereof as a propellant, and the aerosol type hairspray composition having a content of n-butane at least 10% by weight of a button orifice diameter. The container is filled with an aerosol valve having a 0.010 to 0.040 inch, a stem orifice diameter of 0.010 to 0.040 inch, a vapor step orifice diameter of 0 to 0.040 inch or less, and a body orifice diameter of 0.010 to 0.040 inch.

The hair spray according to the present invention comprises 5 to 60% by weight of a mixture of n-butane and dimethyl ether as a propellant, and the aerosol type hairspray composition having a content of n-butane of 10% by weight or more is 0.010 to 0.09 in button orifice diameter. The container is filled with an aerosol valve having a 0.040 inch, a stem orifice diameter of 0.010 to 0.040 inch, a vapor step orifice diameter of 0 to 0.040 inch or less, and a body orifice diameter of 0.010 to 0.040 inch.
