Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is characterized in that when it is squirted into the palm of the hand from an aerosol container containing it, a fine foam is formed, and when left unattended, it forms a foam of approximately 2.
It will not defoam (liquefy) for ~5 minutes, but if you spread the foam with your palm on the desired area (on the skin), it will defoam easily (within about 2 seconds), and the liquefied cologne will not drip or drip. To provide an excellent eau de cologne composition that can be applied uniformly without stickiness, giving a light and good touch, and imparting and emitting a fragrance to the skin.

(Prior Art) Conventionally, the mainstream of products called eau de cologne has been a bottle containing liquid eau de cologne in which fragrance is dissolved in a water-alcohol system. When using the product, it drips from the palm of the hand (run-off).
There is a drawback that it is easy to do.

In addition, in order to increase the amount of flavor added to improve palatability, it is necessary to increase the amount of alcohol and solubilizer (surfactant).

However, in that case, the amount of alcohol blended should be increased (approximately 5
If the amount is 0% by weight or more), the moisture content will inevitably decrease, resulting in faster drying, poor spreadability, and difficulty in uniform application.

In addition, when the amount of solubilizer is increased, it gives a sticky and unpleasant feel to the skin.

In addition, as a means to improve the drawbacks of eau de cologne, there are methods to fill an aerosol container or a pump-type spray container with eau de cologne and spray it in a mist, but it does not adhere to clothing or other parts of the body. This has disadvantages such as staining clothes.

In addition, many foam-like aerosol compositions have been proposed for the purpose of preventing dripping and uniform application, but these aerosol compositions contain humectants and oily ingredients and are designed to form stable foam. Because of this, it contains a large amount of surfactant (foaming agent), which gives a sticky feeling and has problems such as foam that is difficult to disappear.

In Example 6 in Japanese Patent Publication No. 39-2229, Po
lawax (stearyl, alcohol ethylene oxide condensation product) 1.5% by weight, anhydrous ethyl alcohol 5
8.0% by weight, fragrance 2. omt%, 38.0% by weight water and 3% by weight isobutane (propellant) is disclosed.

However, because it contains a relatively large amount of ethyl alcohol, alcohol causes strong irritation to the skin, and the amount of surfactant stearyl alcohol ethylene ethylene oxide condensation product (Polawax) is 1.
Since the amount is as high as 5% by weight, it gives a sticky and unpleasant feel to the skin, making it undesirable as a body cologne. As a result of extensive research, we found that an eau de cologne stock solution containing a specific amount of the specific ingredients listed below has good stability, and an eau de cologne composition (aerosol type) made by adding a specific amount of a propellant to this eau de cologne stock solution can be easily dispensed from an aerosol container into the palm of your hand. When squirted, it forms uniform, fine and beautiful foam without scattering to other parts of the body, and when an appropriate amount of this foam is pressed and spread over the skin with the palm of the hand, it defoams easily (within about 3 seconds) and liquefies. Having learned that cologne can be applied evenly without dripping or stickiness, giving a light feel, and imparting and emitting a mellow fragrance to the skin, the present invention was developed. completed.

(Means for Solving the Problems) That is, the present invention provides a method for treating a fatty acid with a saturated fatty acid residue or an unsaturated fatty acid residue having 12 to 18 carbon atoms, and an added mole number of ethylene oxide of 10 to 30 moles. 0.2 to 1.0% by weight of polyoxyethylene sorbitan monofatty acid ester (weight% is based on the total amount of the final composition. The same applies hereinafter), 5 to 27% by weight of ethyl alcohol, and 0.1 to 5% of fragrance. weight%
This eau de cologne composition is prepared by blending a propellant in an amount of 2 to 20% by weight into a homogeneous eau de cologne stock solution containing 60 to 88% by weight of water.

Examples of the polyoxyethylene sorbitan monofatty acid ester used in the present invention include polyoxyethylene sorbicun monolaurate, polyoxyethylene sorbitan monostearate, and polyoxyethylene sorbitan monostearate having an added mole of ethylene oxide of 10 to 30 moles. Examples include ethylene sorbitan monopalmitate and polyoxyethylene monooleate.

The blending amount of the polyoxyethylene sorbitan monofatty acid ester is preferably 0.2 to 1% by weight based on the total amount of the final composition (eau de cologne composition). 0
．． If it is less than 2% by weight, the cologne composition will not foam even if it is squirted from an aerosol container (no foam will be generated), and if it is more than 1.0% by weight, even if it foams, the foam will be pushed out with the palm of the hand. It is not preferred because it does not defoam (liquefy) easily and also gives a sticky feeling (unpleasant sticky feel) to the skin.

The amount of ethyl alcohol blended is 5 to 27% by weight, preferably 10 to 25% by weight. If it is less than 5% by weight, it will foam as mentioned above and the foam will not defoam even if you press it with your palm.
If the amount is more than 27% by weight, the cologne composition will not foam even if it is squirted, which is not preferable.

The fragrance used in the present invention is essentially an oil-soluble natural fragrance, a synthetic fragrance, etc., and the amount thereof is 0.1 to 5% by weight. If it is less than 0.1% by weight, it will not be possible to impart and emit a sufficient fragrance as an eau de cologne to the skin, and if it is more than 5% by weight, the dispersibility in water-alcohol system and the eau de cologne composition will be affected. This is not preferable because it reduces stability.

Examples of propellants that can be used in the present invention include liquefied petroleum gas (LPG) such as propane, butane, and heptane, chlorofluorocarbon gases such as dichlorodifluoromethane, trichloromonofluoromethane, and tetrafluorodichloroethane, dimethyl ether, and carbon dioxide gas. It can be used singly or in combination of two or more.

The amount of propellant is 2 to 20% by weight, preferably 5 to 20% by weight.
It is 15% by weight. If it is less than 2% by weight, the eau de cologne composition will not eject, and if it is more than 20% by weight, the internal pressure of the aerosol container will be too high, and the foam generated by ejection will quickly defoam, which is undesirable. .

The amount of water added is 60 to 88% by weight.

In addition to the above-mentioned essential ingredients, the cologne composition of the present invention includes:
PH if necessary! Conventional optional components such as II conditioners, sequestrants, preservatives, and dyes may be added within the range that can achieve the object of the present invention.

The eau de cologne stock solution of the present invention is prepared by adding and dissolving the required amount of fragrance and the polyoxyethylene sorbitan monofatty acid ester in the required amount of ethyl alcohol under stirring.
When the required amount of water is gradually added to the rice bran solution, a uniform emulsion is formed.

Next, this stock solution of eau de cologne is delivered into an aerosol container, and then a propellant is blown into the container from a gas cylinder (filling), and the eau de cologne composition of the present invention is produced in the aerosol container, which is used as a product.

(Example) Hereinafter, the present invention will be explained in more detail with reference to Examples.

The percentages shown in the practice mean percentages by weight and also indicate the stock stability,
The test methods for foam-forming properties, defoaming properties, feel, etc. are as follows. In addition, tests other than the stability of the stock solution were conducted by three skilled professional technicians.

(b) Stock solution stability (stability of eau de cologne stock solution) Store the eau de cologne stock solution in a constant temperature bath at 20°C, and observe changes in its appearance 1 hour, 5 hours, and 20 hours after preparing the stock solution. The stability was determined by observing the presence or absence.

Evaluation Judgment Criteria O: The stock solution is stable with no abnormalities even after 20 hours.

Δ: After 5 hours, the stock solution had separated.

x: After 1 hour, the stock solution had separated.

(b) Foam-forming property (foaming property of eau de cologne composition) A sample of the eau de cologne composition contained in an aerosol container was squirted onto the palm of the hand, and the presence or absence of foam formation and the appearance of the formed foam were observed and determined. Note that the subsequent defoaming test was not conducted on samples that did not form foam.

(C) Anti-foaming properties (ease of defoaming) Spray an appropriate amount (approximately 2 g) of the eau de cologne composition sample stored in an aerosol container onto the left palm, place the right palm over the foam, and apply it toward the fingertips. The difficulty in defoaming the foam was determined by stretching the foam until it disappeared (liquefied) and comparing the time required for defoaming (hereinafter referred to as defoaming time) and the number of times of stretching.

Evaluation Judgment Criteria Q: When the foam was pressed and stretched with the palm of the hand, the foam disappeared in one try. Defoaming time: within 1 second Δ: Defoaming occurred in 4 to 4 times when the foam was pressed and stretched with the palm of the hand.
