Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a transparent gel-like fragrance composition. More specifically, the present invention uses a specific higher fatty acid salt as a gel forming agent, a hydrocarbon compound as a carrier,
The present invention relates to a transparent gel-like fragrance composition containing a nonionic surfactant as a clarifying agent, water, and a fragrance.

<Prior art and problems> Various gel-like fragrance compositions have been known in the past, but in the past, a hydrocarbon compound was used as a carrier for an oil-based gel-like fragrance, and a sodium salt of a higher fatty acid was used as a gel-forming agent. In this case, a gel-like fragrance with good transparency could not be obtained.

<Object of the Invention> An object of the present invention is to provide a gel-like fragrance composition that continuously emits a fragrance over a long period of time and is transparent even at temperatures below 10°C.

<Means for solving the problems> According to the invention, sodium myristate, sodium palmitate, sodium stearate, sodium arachinate, sodium behenate, sodium oleate and mixtures thereof are selected from the group consisting of It is characterized by containing 1 to 15% by weight of a higher fatty acid salt, 40% by weight or more of a hydrocarbon compound, 1 to 20% by weight of a nonionic surfactant, 0.3 to 15% by weight of water, and 0.1 to 40% by weight of a fragrance. A transparent gel-like fragrance composition is provided.

The gel forming agent in the gel fragrance composition of the present invention is selected from the group consisting of sodium myristate, sodium palmitate, sodium stearate, sodium arachinate, sodium behenate, sodium oleate, and mixtures thereof. Use higher fatty acid salts.

In the transparent gel fragrance composition of the present invention, the above-mentioned higher fatty acid salt is used in an amount of 1 to 15% by weight. If the higher fatty acid salt is less than 1% by weight, the strength (hardness) of the gel will be insufficient, and if it is more than 15% by weight, it will be difficult to form a gel and the residual amount will be large, which is not preferable.

In the transparent gel-like fragrance of the present invention, 1 to 20% by weight of a nonionic surfactant is used as a clarifying agent.
Preferably it is added in an amount of 1 to 15% by weight. If the amount of the nonionic surfactant is 1% by weight, the gel fragrance composition cannot be made transparent at temperatures below 10°C;
If it exceeds % by weight, the amount remaining after evaporation becomes large, which is not preferable.

The nonionic surfactants that can be used in the present invention include hydrophilic and lipophilic balance values (hereinafter referred to as
A nonionic surfactant having an HLB of 7 to 20 can be preferably used. When HLB is less than 7 or more than 20, desired transparency may not be obtained. Among these nonionic surfactants, polyoxyethylene compounds are particularly preferred. For example, polyoxyethylene glyceryl isostearate, polyoxyethylene glyceryl diisostearate, polyoxyethylene glyceryl triisostearate, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan distearate, polyoxyethylene sorbitan tristearate. Polyoxyethylene sorbitan monoisostearate, polyoxyethylene sorbitan diisostearate, polyoxyethylene sorbitan triisostearate, polyoxyethylene nonyl phenyl ether, polyoxyethylene octyl phenyl ether, polyoxyethylene hardened castor oil, polyoxyethylene behenyl ether, polyoxyethylene stearyl ether, polyoxyethylene cetyl ether, polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, polyoxyethylene octyl ether, polyoxyethylene-2-hexyldecyl ether, polyoxy ethylene-2
-heptyl undecyl ether, polyoxyethylene-2-decyltetradecyl ether, polyoxyethylene-2-decylpentadecyl ether, polyoxyethylene polyoxypropylene cetyl ether, polyoxyethylene polyoxypropylene decyl tetradecyl ether, polyoxy Ethylene secondary alkyl ether (manufactured by Nikko Chemicals, product name "BT series", Nippon Shokubai Chemical Co., Ltd. product names "Softanol series", "Softanol M series", "Softanol L series")
etc.

Among these, polyoxyethylene polyoxypropylene cetyl ether, polyoxyethylene polyoxypropylene decyl tetradecyl ether, polyoxyethylene oleyl ether, polyoxyethylene hydrogenated castor oil, polyoxyethylene secondary alkyl ether, polyoxyethylene glycerin Particularly preferred are lyl triisostearate, polyoxyethylene-2-decyltetradecyl ether, ponooxyethylene-2-heptyl undecyl ether, polyoxyethylene nonyl phenyl ether and mixtures thereof.

As the polyoxyethylene secondary alkyl ether, for example, a polyoxyethylene adduct of a secondary alcohol having 10 to 14 carbon atoms can be used.

The number of moles of polyoxyretylene and polyoxypropylene added is preferably 1 to 50 moles. A desired HLB may not be obtained outside this range.

In the present invention, 40% by weight or more of a hydrocarbon compound is used as a carrier in the composition. Examples of hydrocarbon compounds include terpene hydrocarbons, normal paraffin hydrocarbons, and isoparaffin hydrocarbons. Preferred terpene hydrocarbons include, for example, α-pinene, β-pinene, limonene, dipentene, p-cymene, 3-carene, γ-terpinene, myrcene, ocimene, alloocimene, p-menthane, pinane, terpinolene, 1-p- Menthene, limonene dimer, dipentene dimer or hydrogenated products thereof, mixtures thereof, or mixtures thereof, such as natural essential oils such as turpentine oil whose main component is α-pinene, β-pinene, d- Examples include orange oil and lemon oil, which contain limonene as a main component.

In particular, d-limonene is an important component of citrus-based fragrances because of its aroma, and is particularly excellent as a solvent for citrus-based fragrances. In particular, when these terpene-based hydrocarbons are used as a carrier, they are good for bringing out natural flavors, and they also have the characteristic that the scent of the aromatic agent does not change until the end.

In addition, for normal paraffinic hydrocarbons and isoparaffinic hydrocarbons, the specific formula is
_{C8H18 to C18H38 , more} preferably _{C10H22 to C16H34}
are particularly suitable for the present invention.

Normal paraffin hydrocarbons, isoparaffin hydrocarbons, and terpene hydrocarbons can be mixed and used in any proportion. Even when such a mixed hydrocarbon compound is used, it is included in the transparent gel fragrance composition of the present invention. The amount added
If it is less than 40% by weight, the higher fatty acid salt as a gel forming agent becomes difficult to dissolve, which is not preferable.

Water is contained in a range of 0.3 to 15% by weight. If it is less than 0.3% by weight, the gel forming agent will not dissolve, and if it exceeds 15% by weight, each component will be likely to separate.

Furthermore, in the present invention, a solubilizing agent such as glycols, glycol monoethers or ethyl alcohol may be mixed and used in an amount of up to 10% by weight. Preferred glycols include, for example, hexylene glycol, dipropylene glycol, diethylene glycol, 1,6-hexanediol, 1,
5-pentanediol, 2,2-dimethyl-1,
Examples include, but are not limited to, 3-propanediol or mixtures thereof.

Glycol monoethers include glycol monomethyl ether, monoethyl ether,
3-Methyl-3-methoxybutanol or a mixture thereof is preferred, but is not necessarily limited to such ethers. By adding these solubilizers, the gel forming agent can be easily dissolved and the transparency may be further improved.

In the transparent gel fragrance composition of the present invention, any fragrance can be used as long as it is soluble in the hydrocarbon compound. The fragrance is used in a range of 0.1 to 40% by weight. If it is less than 0.1% by weight, it will not be possible to obtain a suitable fragrance, while if it is used in excess of 40% by weight, it will not be very effective.

In addition, in the transparent gel fragrance composition of the present invention, other additives such as antioxidants (such as BHT) and fatty acid metal salts as thickening stabilizers (such as aluminum stearate, stearin etc.) may be added as necessary. Other additives such as ethylcellulose, ethylhydroxyethylcellulose, and pigments can be used as appropriate.

When producing the transparent gel-like fragrance composition of the present invention, the gel-forming agent, nonionic surfactant, hydrocarbon compound, and water are heated to a temperature of 70 to 90°C to completely dissolve the gel-forming agent. Heat and stir until heated. Then,
After cooling to 70-80℃, add the desired fragrance,
After thorough stirring and cooling, a transparent and stable gel-like fragrance can be obtained.

<Effects of the Invention> The transparent gel-like fragrance composition of the present invention produced in this manner is transparent and remains transparent even at temperatures below +10°C, and continues to emit a fragrance for several months. It will evaporate after a while.
