JPH02300108A - Non-emulsion-type foaming aerosol composition - Google Patents

Abstract

PURPOSE:To obtain a non-emulsion type foaming aerosol composition having excellent detergency, applicability and stability and useful as a cleansing agent for oily cosmetic, etc., by using a liquid oil component and a propellant in combination with an organic silicone resin. CONSTITUTION:The objective non-emulsion type foaming aerosol composition contains a liquid oil component (e.g. avocado oil, camellia oil, squalane and lauryl alcohol), an organic silicone resin (preferably having an average molecular weight of about 1,500-10,000) and a propellant (e.g. trichlorofluoromethane or propane). The preferable amounts of the liquid oil component, the organic silicone resin and the propellant are about 30-75wt.%, >=0.1wt.% or thereabout and about 3-90wt.%, respectively. The defoaming time can be prolonged and the foam can be stabilized by adding water to the system to an extent not to deteriorate the stability. The composition is useful e.g. as a cleansing agent for oily cosmetic and has excellent detergency, applicability and stability.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a non-emulsifying foam aerosol composition useful as a cleansing agent for oil-based cosmetics, and more specifically, the present invention relates to a non-emulsifying foam aerosol composition that is useful as a cleansing agent for oil-based cosmetics. The present invention relates to a non-emulsifying foam aerosol composition containing a propellant and a propellant, which has excellent detergency, usability, and stability.

[Prior Art] Conventionally, aerosol compositions include stable foam, rapidly disintegrating foam, spray type, etc. depending on the combination of stock solution and propellant. The stable foam is formed of an O/W emulsion consisting of two phases: an inner phase consisting of an oil phase in which a propellant is dissolved, and a main phase in which the propellant has poor solubility. Foam type aerosol compositions of O/W type emulsions are available as cleansing cosmetics, but they have low cleaning power and are unsuitable for cleaning oil-based makeup. Oil is the most effective for removing oil-based makeup, and it is most preferable if a stable foam can be obtained with a undiluted solution of oil and propellant, but oil and propellant are very compatible and the propellant evaporates quickly. Therefore, it was difficult to obtain stable foam.

[Problem to be Solved by the Invention 1] As a result of studying the above-mentioned problems, the present inventor has found that a composition that is stable and has excellent detergency can be obtained by using an organic silicone resin, and has completed the present invention. reached.

[Means for Solving the Problems] That is, the present invention provides a liquid oil and an organic silicone 4+.
The present invention relates to a non-emulsifying foam aerosol composition containing 4 fats and a propellant.

Hereinafter, the configuration of the present invention will be explained in detail.

The liquid oil used in the present invention is one that is liquid at room temperature, such as avocado oil, etc. ~ Ki oil, turdle oil, macadamia nut oil, corn oil, mink oil,

Higher alcohols such as octyldodecanol, methylpolysiloxane, methylphenylpolysiloxane, methylhy-1herodienepolysiloxane, silicones such as dicamethylpolysiloxane, isopropyl myristate, isopropyl palmitate, hexyl ester, oleyl, Examples include esters such as decyl oleate, ocdyldodecyl myristate, hexyldecyl dimethyloctanoate, diethyl phthalate, and dibutyl phthalate.

The amount of liquid oil used in the present invention is preferably 10 to 89.99% by weight, more preferably 30 to 75% by weight based on the total amount of the stock solution.

The organic silicone (l (fat) used in the present invention is R3S
i 01/2 unit, R2S i O unit, RS i
It consists of an appropriate combination of 03/2 units and 5i02 units, and the ratio is determined by the average formula RnS i O(4-o1/2
(R represents a hydrocarbon group or phenyl group with a cooking number of 1 to 6, and n represents a value of 1.0 to 1.8.) It is desirable to have an average molecular weight. This silicone resin can be easily obtained by mixing corresponding known silanes, diluting with a solvent such as toluene or hexazide, hydrolyzing the mixture, and then polymerizing it by heating. 5i0
Similar silicone resins can be obtained by using water glass in addition to the silanes for the 2 units.

The amount of organic silicone resin blended is 0.01 in the total amount of the stock solution.
It is at least 0.05% by weight, more preferably at least 0.1% by weight. If the amount is less than 0.01% by weight, stable foam cannot be obtained.

As the propellant used in the present invention, propellants commonly used in aerosol products can be used.

Specific examples include chlorofluorocarbore such as trichlorofluoromethane, dichlorodifluoromethane, dichlorofluoromethane, trichlorotrifluoromethane, dichlorotetrafluoroethane, propane, isobutane,
Liquefied petroleum gas (normal butane and its mixtures)
It is a liquefied gas such as LPG (hereinafter abbreviated as LPG). In addition to these propellants, dimethyl ether, carbon dioxide, and nitrogen gas may also be used. These gases can be used alone or in combination!
Can be used together. The blending amount is preferably 3 to 90% by weight. If it is less than 3% by weight, good foam cannot be obtained.

In addition to the above-mentioned essential ingredients, the foam-type aerosol composition of the present invention contains preservatives, colorants, powders, antioxidants, fragrances, surfactants, drugs, solid oils, semi-solid oils, alcohol, and moisturizers. Agents, etc. can be added. Furthermore, adding water within a range that does not impair the stability of the system can roughly lengthen the defoaming time and stabilize the foam.

[Effect of the invention] The non-emulsifying foam aerosol composition of the present invention can be used for oil-based makeup i.
It is useful as a positive cleansing agent, etc., and has excellent detergency, usability, and stability.
