Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oily foamy aerosol composition as an oily cosmetic, and more specifically, it is characterized by containing a dextrin fatty acid ester as a foaming aid and is stable and stable. The present invention relates to an oily foamable aerosol composition having excellent properties.

[0002]

2. Description of the Related Art Conventionally, when aerosolizing an oily composition or a non-emulsifying oily composition, it has been difficult to form a foam because the compatibility of the propellant and the oil is too good. No. 300108 or JP-A-3-50289.
Japanese Patent Publication discloses a non-emulsifying foam aerosol composition.

Further, O / W type stable foam, quick break type foam, jet type, slow foam type and the like have been conventionally known.

[0004]

However, among the conventional techniques, JP-A-2-300108 or JP-A-3-300108.
The non-emulsifiable foamable aerosol composition of No. 50289 has insufficient foamability and foam stability especially at a low temperature of 5 ° C. or lower, and has satisfactory results as compared with a normal O / W type foamable aerosol. Not obtained.

Further, cosmetics such as O / W type stable foam, quick break type foam, jet type and slow foam type are so-called O / W type whose outer phase is a water phase, and are propellants. Various productions are possible by the combination of the above and the stock solution, but a stable foam is not obtained only with the oily component or with the non-emulsifying oily composition.

The present inventor has been made to solve the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide an oily foam aerosol composition which is stable and has excellent feeling in use.

[0007]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have found that the incorporation of a dextrin fatty acid ester as a foaming auxiliary agent results in an oily foam excellent in stability and usability. It was found that a volatile aerosol composition was obtained, and the present invention was completed.

That is, the present invention relates to an oil-based foamable aerosol composition containing a dextrin fatty acid ester as a foaming aid and an oily component.

The dextrin fatty acid ester used as a foaming aid in the oily foamable aerosol composition of the present invention is a compound obtained by reacting dextrin with a fatty acid chloride for esterification. The ester group is an ester group of a saturated or unsaturated fatty acid having 8 to 22 carbon atoms, preferably a saturated or unsaturated fatty acid having 12 to 18 carbon atoms. Specific examples of the dextrin fatty acid ester include dextrin laurate, dextrin myristate, dextrin palmitate, dextrin oleate, dextrin stearate, and coconut oil fatty acid dextrin.

The blending ratio of the dextrin fatty acid ester in the oily foamable aerosol composition of the present invention is 0.01% to 40% by weight, preferably 0.05% to 10% with respect to the oily component. It is the following. 0.
If it is less than 01%, foaming is difficult, and if it exceeds 40%, the oily component is gelated and foaming becomes difficult.

The oily component used in the oily foamable aerosol composition of the present invention is a liquid mineral oil or fats and oils, for example, in the case of hydrocarbons, liquid paraffin, light liquid isoparaffin, squalene, squalane, α-olefin oligomer, etc. There are corn oil, safflower oil, avocado oil, rice germ oil, wheat germ oil,
Almond oil Soybean oil, rapeseed oil, sesame oil, camellia oil, southern oil, persic oil, olive oil, tea seed oil, perilla seed oil, mink oil, castor oil, linseed oil, evening primrose oil, borage oil, glyceryl triisooctanoate, tri ( Caprylic / caprylic acid glyceryl, triisopalmitic acid glyceryl, etc., and ester oils such as isopropyl myristate, isopropyl palmitate, cetyl octanoate, decyl oleate, oleyl oleate, octyldodecyl oleate, octyl stearate, benzoic acid. There are alkyl esters, octyldodecyl myristate, neopentyl glycol dioctanoate, neopentyl glycol dicaprate, diisostearyl adipate, jojoba oil, etc., and silicone oils such as dimethyl polysiloxane and methyl phenyl Polysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, methyl hydrogen polysiloxane, etc., higher alcohols such as oleyl alcohol, isostearyl alcohol, octyldodecanol, etc., fatty acids oleic acid, coconut oil fatty acid , Isostearic acid, linoleic acid, linolenic acid and the like.

In order to use the oily foamable aerosol composition of the present invention as an oily cosmetic, various surfactants, ultraviolet absorbers, antioxidants, preservatives, bactericides, resins, powders,
Coloring agents, alcohols, polyhydric alcohols, water-soluble polymers, protein hydrolysates or their derivatives may be added. A small amount of water may be added to improve the stability of the product.

The composition of the present invention generally contains one or more kinds of liquefied petroleum gas, dimethyl ether, nitrogen, oxygen, carbon dioxide, chlorofluorocarbon and the like as a propellant, as in a usual aerosol product. However, so-called non-gas type foaming is also possible by blowing air and mixing without blending a propellant.

The oily foamable aerosol composition of the present invention comprises:
It is useful as an oily cosmetic, for example, an oily cleansing agent, a tanning oil, a body oil, an oily bath agent and the like.
