Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a gel composition, more particularly to a gel composition containing lanolin fatty acid alkali metal salts, which can be used as a fragrance or a cleaning agent. .

(Prior Art) Conventionally, when preparing a gel fragrance composition, fatty acid sodas such as sodium stearate and sodium palmitate are combined with terpene hydrocarbons and isoparaffin hydrocarbons, as well as glycols, glycol monoethers, and ethyl alcohol. However, the gel compositions obtained in this way all have a certain hardness, and it is not possible to obtain a soft gel composition in the form of a paste. However, it was also not possible to adjust the hardness of the gel composition.

(Problems to be Solved by the Invention) According to the present invention, it is possible to easily adjust the hardness of not only a hard gel composition but also a soft paste gel composition. The purpose of the present invention is to provide a gel-like composition having the following properties.

(Means for solving the problem) According to the present invention, lanolin fatty acid alkali metal salt 2-2
Provided is a gel composition characterized in that it contains 2% by weight of volatile terpene hydrocarbons and/or 40% by weight or more of volatile terpene hydrocarbons and/or isoparaffinic hydrocarbons.

The present invention will be explained in more detail below.

In the present invention, volatile terpene hydrocarbons and/or isoparaffin hydrocarbons are used instead of conventionally used solvents such as glycols, glycol monoethers, and ethyl alcohol.

As the terpene hydrocarbon used in the present invention, any volatile terpene hydrocarbon may be used.

Preferred volatile terpene hydrocarbons include:

For example, α-pinene, β-pinene, limonene, dipentene, p-cymene, 3-carene, γ-terpinene, myrcene, ocimene, alloocimene, p-menthane, binane, turbinolene, 1-p-mentene and limonene dimer, dipentene. Dimer or its hydrogenated product, or a mixture thereof, or a mixture thereof, such as natural essential oils, such as turpentine oil whose main component is α-pinene, β-pinene, or d-limonene. Examples include orange oil, lemon oil, etc.

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 hydrocarbons are used as a solvent, they are good for bringing out a natural flavor, and the aroma of the aromatic agent does not change easily until the end. Although these natural terpene hydrocarbons contain small amounts of oxygen-containing compounds such as alcohols, ketones, and aldehydes, they do not affect gel formation, so mixing in oxygen-containing compounds is not a problem. The isoparaffinic hydrocarbons that can be used in the general formula C: n H, n+, (n is 8 to
(an integer of 20), is itself non-toxic, has very little odor, has moderate volatility, and is inexpensive, so it is very preferable as a solvent.

Among imparaffinic hydrocarbons, the characteristic formula is C.

Hl, -C,,H,, more preferably C1,Ho~
C,, H□, are particularly suitable for the present invention. It is also possible to use a mixture of isoparaffin hydrocarbons and volatile terpene hydrocarbons. The use of such mixed volatile hydrocarbons is also included in the gel composition of the present invention.

The gel composition of the present invention contains a lanolin fatty acid alkali metal salt. Lanolin fatty acid alkali metal salt is prepared by dissolving lanolin fatty acid in a volatile terpene hydrocarbon and/or isoparaffin hydrocarbon under heating, and then preparing an aqueous alkali metal salt solution, such as an aqueous solution of caustic soda or caustic potash (the water in the R final composition). (preferably in an amount of 0.2 to 15% by weight) into the final composition, or by preparing a lanolin fatty acid alkali metal salt in advance and carbonizing the volatile terpene. To prepare in advance lanolin fatty acid alkali metal salt which may be heated and dissolved in hydrogen and/or isoparaffinic hydrocarbon.

It is obtained by heating and dissolving lanolin fatty acids in an alcohol such as ethanol, reacting with an aqueous solution of an alkali metal salt such as caustic soda or caustic potash, and then removing ethanol and water by evaporation.

The lanolin fatty acids used in the present invention contain large amounts of isofatty acids and hydroxy fatty acids in addition to straight chain fatty acids.

The carbon number of such lanolin fatty acids is C-7 to C-41.
In particular, fatty acids with a carbon number of C-22 or higher (consisting of branched fatty acids and oxyfatty acids) are non-crystalline, but have a high melting point (70"C or higher), and contain such fatty acids. Lanolin fatty acids provide gel-like compositions with good water-holding properties.On the other hand, they are stable against external water and have the property of completely repelling water.

Preferred lanolin fatty acids are those obtained by hydrolyzing lanolin and have a low iodine value.

These fatty acids can be produced industrially and are commercially available.

In the gel composition of the present invention, myristic acid, balmitic acid, isopalmitic acid, stearic acid, isostearic acid, oleic acid, behenic acid, etc. can be used and reacted together. By using these acids, the hardness and appearance of the gel composition can be adjusted appropriately.

In the present invention, the ingredients are blended so that the final gel composition contains 2 to 22% by weight of lanolin fatty acid alkali metal salt and 40% by weight or more of volatile terpene hydrocarbons and/or isoparaffinic hydrocarbons. Make it. If the lanolin fatty acid alkali metal salt is less than 2% by weight, a gel-like composite acid with good stability cannot be obtained, while if it exceeds 22% by weight, the non-volatile components are too large and the desired volatility cannot be obtained. If less than 40 weight by weight of undesirable volatile terpene hydrocarbons and/or isoparaffin hydrocarbons are contained, a gel fragrance composition having desired volatility cannot be prepared.

In the present invention, a fragrance may be included in the gel composition. Any fragrance can be used as long as it is soluble in volatile terpene hydrocarbons and/or isoparaffin hydrocarbons. Although the amount of fragrance added is not particularly critical, it is usually preferably blended within the range of 0.1 to 40% by weight.

In addition, in the gel composition of the present invention, other additives 1 such as antioxidants (such as BHT) and fatty acid metal salts as thickening stabilizers (such as aluminum stearate, magnesium stearate, etc.) may be added as necessary. Dextrin fatty acid ester (aluminum 2-ethylhexylate, etc.), ethylhydroxyethylcellulose, and other additives can be used as appropriate.

In producing the gel composition of the present invention, lanolin fatty acids are dissolved in volatile terpene hydrocarbons and/or isoparaffin hydrocarbons at a temperature of 60 to 70°C, and each component is stirred and mixed until uniform. Then, an aqueous caustic alkali solution is added and stirred at a temperature of 70 to 80°C until the saponification reaction or neutralization reaction is completely completed. When the reaction is completed, the solution becomes transparent.Next, perfume and other ingredients are added as necessary, the mixture is further stirred at 70°C or higher, and the mixture is filled into a container to obtain a solid gel-like composition. In addition, after adding fragrance and other ingredients, a soft paste-like gel composition can be obtained by cooling to about 30"C without stirring. °Prepare alkali metal salt, 70-80℃
After stirring and mixing with volatile terpene hydrocarbon and/or isoparaffin hydrocarbon until completely dissolved.

It may be processed in the same manner as described above. Lanolin fatty acid alkali metal salt is prepared by dissolving lanolin fatty acid in ethanol at 60-70°C and adding aqueous caustic alkali solution to 70-70°C.
It can be easily obtained by reacting at °C and then evaporating ethanol and water.

(Effects of the Invention) In the present invention, the hardness of the gel composition can be easily changed by adjusting the simple operations of heating, stirring and cooling. A gel composition can be obtained. Furthermore, the gel composition of the present invention is very stable and does not separate or dissolve over a long period of time.
