Description

  The present invention relates to an aerosol cosmetic, and more particularly to an aerosol cosmetic suitable for post-foaming.

  Post-form (post-foaming) cosmetics are normal cosmetics at the time of discharge, and are a form of foam that gradually foams in the process of applying cosmetics, such as applying it. It has both the feeling of use of cosmetics and the feeling of use of foam cosmetics, and has excellent use characteristics. For this reason, massage and pack cosmetics of this dosage form have been developed. (For example, refer to Patent Document 1, Patent Document 2, and Patent Document 3) However, in such a post-foamed aerosol cosmetic, gas must be held inside the ejected product when ejected, A high-hardness content and a mechanism for extruding the mixture of the content and gas are required. An ordinary so-called dip tube type aerosol can is filled with an emulsion and a gas component for foaming it. However, it is difficult to realize the structure in which the emulsion is discharged as a foam from a nozzle using the pressure of the gas component. As a means for overcoming this point, the content discharged into one space portion inside the two-chamber container separated by a partition wall that is movable and capable of separating the content is filled, and the content content is filled in the other space portion. An aerosol container (a two-chamber type aerosol container) filled with a compressed gas to be pressurized to extrude has been developed. (For example, refer to Patent Document 4, Patent Document 5, and Patent Document 6) With such a form, it has become possible to discharge a high-hardness content, but for foaming following discharge, the hardness of the content As the temperature increased, the temperature dependence of hardness increased, and the temperature difference in usability tended to become remarkable. In particular, it was very difficult to maintain post-foaming at 40 ° C. This is because the contents cannot contain the foaming gas. In other words, it has been desired to develop a content that does not decrease in hardness and has excellent gas inclusion ability even in a high temperature range of about 40 ° C.

  On the other hand, a foam aerosol containing 1) 40-50% by weight of glycerin, 2) 25-40% by weight of water, 3) 3-5% by weight of at least two polyglycerol fatty acid esters and 4) 8-20% by weight of oil. No cosmetics are known, and it is not known at all that a foam-type foam aerosol cosmetic can be obtained by taking such a constitution, and foaming without temperature dependency is obtained.

JP 2003-238352 A JP 10-316532 A Japanese Patent Laid-Open No. 9-77629 JP 11-349934 A Japanese Patent Laid-Open No. 10-72074 Japanese Patent Laid-Open No. 09-19398

  The present invention has been made under such circumstances, and is suitable for post-foaming aerosol cosmetics, which does not decrease in hardness and has excellent gas inclusion ability even in a high temperature range of about 40 ° C. It is an issue to provide.

In view of such circumstances, the present inventors have sought contents suitable for post-foaming aerosol cosmetics that do not decrease in hardness and have excellent gas inclusion ability even in a high temperature range of about 40 ° C. As a result of earnest research efforts, 1) glycerin 30 to 60% by mass, 2) water 10 to 50% by mass, 3) at least two polyglycerol fatty acid esters 3 to 5% by mass, and 4) oil 8 to 20 It has been found that a material containing 5% by mass has such characteristics, and has completed the invention.

Is an essential component. In the aerosol cosmetic composition of the present invention, such a component holds the foaming gas in the contents and releases it in use, and the temperature of the contents is adjusted to a temperature suitable for foaming in use. It also has the effect of raising. If the amount of glycerin is less than the above range of content, there may be cases where post-foaming is not preferred because gas retention is not sufficient or sufficient temperature rise for foaming cannot be obtained during use. If the amount of glycerin is too large, foam formation may be inhibited and foaming may not occur.

(2) Water which is an essential component of the aerosol cosmetic of the present invention The aerosol cosmetic of the present invention is a foam aerosol cosmetic and contains 10 to 50% by mass of water, more preferably 15 to 40% by mass. It is characterized by that. In the cosmetic of the present invention, water is an essential component for foam formation. If the amount is less than the above range, foam formation may be inhibited. There are cases where the effect is not obtained and foaming is inhibited.

(3) Polyglycerin fatty acid ester which is an essential component of the aerosol cosmetic of the present invention The aerosol cosmetic of the present invention is a foam aerosol cosmetic, comprising 3 to 5% by mass of at least two polyglycerin fatty acid esters. Preferably it contains 3.5-4.5 mass%, It is characterized by the above-mentioned. As the fatty acid ester of polyglycerol, a highly hydrophilic one is preferable, and specifically, a monoester, diester or triester having a polymerization degree of glycerol of 6 or more, more preferably 8 or more is preferable. The fatty acid residue is not particularly limited as long as it is a fatty acid usually used in cosmetics, but is not limited to stearic acid residue, palmitic acid residue, myristic acid residue, lauric acid residue, olein. Examples include acid residues, linoleic acid residues, isooctanoic acid residues, isostearic acid residues and the like. Specifically, hexaglycerin monostearate, octaglycerin monostearate, decaglycerin monostearate, decaglycerin distearate, decaglycerin tristearate, hexaglycerin monooleate, octaglycerin monooleate, decaglycerin monooleate, Examples include decaglycerin diolate and decaglycerin trioleate.

Among the above, liquid ones are hexaglycerin monooleate, octaglycerin monooleate, decaglycerin monooleate, decaglycerin diolate, and decaglycerin trioleate. In the combination of liquid and non-liquid at 1 atm 25 ° C., the mass ratio of liquid to non-liquid is preferably 2: 3 to 3: 2. By such a combination, a content suitable for post-foaming is formed.

(4) Oil which is an essential component of the aerosol cosmetic of the present invention The aerosol cosmetic of the present invention is a foam aerosol cosmetic, characterized by containing 8 to 20% by mass and 10 to 18% by mass of oil. To do. Here, oil is a component for cosmetics and has fluidity under conditions of 1 atm and 25 ° C., and esters of hydrocarbons, silicones, fatty acids and monohydric or dihydric or higher alcohols. Etc. can be illustrated.

  Among the above components, components other than the gas component for post-foaming can be processed in accordance with a conventional method, and can be manufactured by filling an aerosol can together with the gas component and sealing. As an aerosol can, there is no particular limitation, but due to the property that the high-viscosity and high-hardness contents can be ejected without increasing the gas pressure coexisting with the contents, it is separated by a partition that can move and separate the contents. The contents to be discharged into one space inside the two-chamber container and the gas component to contribute to foaming are filled, and the compressed gas to be pressurized to push out the contents is filled into the other space. It is preferred to use a two-chamber container with a structure to be filled. In this case, the pressure of the compressed gas for extrusion needs to be slightly higher than the pressure in the inner bag, and specifically, it is preferably high at a level of 0.1 hp or more.

  Under such sealed conditions, the pressure in the container (inner bag) is at least 0.05 hP at 5 ° C., and the pressure difference between the gas pressure in the container (inner bag) and the atmosphere is 0. It is preferably 2 hp or less. Outside this range, the post-foaming form may not be maintained.

  Hereinafter, the present invention will be described in more detail with reference to examples, but it goes without saying that the present invention is not limited to such examples.

  The aerosol cosmetic of the present invention was produced according to the formulation shown below. That is, (a) and (b) were each heated to 80 ° C., (b) was gradually added to a under stirring, and then stirred and cooled to produce the contents. 50 parts by mass of the contents together with 1 part by mass of gas are filled in the inner bag of the two-chamber type aerosol container, the gas is filled between the inner bag and the outer container, and the container is hermetically sealed. Certain cosmetic cosmetics 1 and 2 and Comparative Examples 1 and 2 were obtained.
