- Powder-containing lotions that utilize the inherent properties of powder, such as water-based foundations and sebum control lawns, are made by mixing the powders together and dispersing them uniformly when using them. It is known to form a suspension and apply it to the skin of various parts of the body using a cosmetic product or by hand.

(Problem to be solved by the invention) However, when conventional lotions containing powder, such as calamine lotion and water-based foundation lotion, are used with cosmetic cotton, the powder is mixed into the cosmetic cotton. Patting is performed to reduce the amount of powder that remains and adheres to the skin, and to transfer the remaining powder from cosmetic cotton to the skin, but at this time, the lotion often scatters, and it may damage the surrounding area or clothing. Powder contaminated by powder in water and incorporated into the fiber structure of clothing has the disadvantage that it is difficult to remove even when washed, resulting in stains.

In addition, conventional powder-containing lotions have drawbacks such as when they are applied directly to the skin by hand, the lotion spills or splatters from the hands, staining surrounding areas and clothes with the powder in the lotion. It had

The present invention has been intensively researched in view of the above-mentioned drawbacks of the conventional technology, and has excellent practical properties without staining the surroundings or clothes when applied to the skin, as well as good shaking dispersibility and storage stability. An object of the present invention is to provide a self-spraying powder-containing lotion composition having the following properties.

(Effects of the Invention) When the self-spraying lotion composition of the present invention is used, for example, by shaking it, the powder and propellant are easily dispersed uniformly, and the lotion is automatically sprayed in the form of foam from the aerosol container. When applied to the skin, it does not stain the surrounding area or clothes with powder, has excellent practical properties, and also exhibits good shaking dispersibility and storage stability.

The present invention has the above-mentioned unique and remarkable effects, such as aerosol calamine lotion (anti-inflammatory lotion), aqueous foundation soap, and sebum control lotion.

The present invention provides a self-spraying foamy lotion useful as a conditioner, acne cream, etc.

(Example) EXAMPLES Hereinafter, the present invention will be explained with reference to examples.

The parts shown in the examples mean parts by weight. The properties (shaking dispersibility, storage stability, practical properties) of the self-spraying foamy lotion shown in the examples were investigated.

The test method is as follows.

(1) Dispersibility by shaking A sample composition filled in a transparent pressure-resistant glass aerosol container was manually shaken vigorously up and down and allowed to stand at room temperature for 7 days. After a few days had passed, the sample was manually shaken vigorously up and down again to determine the number of times of shaking required until the components were uniformly mixed. If the required number of shaking is 1 to 5 times, it is very good (extremely easy to use. The code is ◎), if it is 6 to 10 times, it is good (easy to use. The code is ○), and if it is ii to 20 times, it is good. It was classified as somewhat poor (slightly difficult to use, code: △), and if it was repeated 21 times or more, it was considered poor (slightly difficult to use, code: X).

Incidentally, the greater the number of times of shaking required, the more troublesome it is to shake and the more difficult it is to use.

(2) Storage stability test As in the case of (1) above, 80 bottles of each sample containing the composition were placed in 4 transparent pressure-resistant glass cracked aerosol containers.
After the above-mentioned evaluation in (1) when stored in a constant temperature room at 0° C. for 6 months and shaking, the ejection state when injected into the atmosphere was examined. The evaluation results are marked O if all of the samples (80) were able to eject smoothly, and marked X if even one nozzle was clogged with powder.

(3) Practical characteristics test A fire test was conducted on each sample by 20 testers.

The evaluation method was as follows. First, when using it, shake the powder and propellant evenly, and then automatically spray the foam into the atmosphere from the aerosol container, then take it directly in your hands and apply it to the skin of various parts of the body (especially the face, shoulders, hands, feet, and back). The applicability was investigated to see if it could be applied easily without scattering or dripping. The results are shown by the number of people who answered "good" or "somewhat good" among those who answered "good", "somewhat good", "fair", or "poor".

The specifications of the aerosol containers used in each of the above tests are as follows.

a Bottle: Transparent pressure-resistant glass bottle or aluminum can (epoxy phenol resin coated) b Valve: Nylon resin, stem hole 0.5
mm φ Install the valve.

Next, components (1) and (2) were press-fitted to prepare each kafmin rosi soda.

(3) Characteristics The various tests described above were conducted on each of the obtained calamine lotions, and the results of examining the characteristics are shown in Table 1. As shown in Table 1, good shaking dispersibility, storage stability, and practical properties were exhibited when the amount of nonionic surfactant was 0.01 to 5% by weight based on the total weight of the composition. However, when the blended amount of nonionic surfactant was less than 0.01% by weight (Comparative Example 1), the propellant could not be uniformly fractionated into the system even by shaking, and was ejected from the aerosol container into the atmosphere. When it was mixed, it did not form a uniform foam. In other words, when applied to the skin, it scattered or dripped, resulting in poor practical properties. 6% by weight
In the above (Comparative Example 2), the cafmin lotion was formed into a uniform foam, but the foam did not disappear on the desk (difficult to apply), and the nonionic surfactant had a sensual stickiness, which caused some problems in terms of practical properties. Undesirable.

Furthermore, an anionic surfactant (here, sodium N-fluoroyl L-glutamate).

A cationic surfactant (here, stearyltrimethylammonium chloride) and an amphoteric surfactant (here, a
2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine) agglomerated the powder, which clogged the valve of the aerosol container and made it unusable.

Examples 5-9. Comparative Examples 8 and 4 (Sebum control low scene) (1) Prescription (2) Manufacturing method After uniformly dissolving and dispersing the ingredients (■ to ■), place them in a designated aerosol container and degas the upper air using a vacuum pump. while installing the specified valve. Next, component (1) was press-filled to prepare a sebum control row.

(3) Characteristics The various tests described above were conducted on the obtained sebum control lotion, and the results of examining the characteristics are shown in Table 1. As shown in Table 1, when the powder content is 0.1 to 80% by weight based on the total weight of the composition, good shaking dispersibility, storage stability,
It showed practical characteristics. However, when the amount of powder blended was less than 0.1% by weight, there was no degreasing ability and sebum control was not possible, resulting in poor practical properties. Furthermore, the amount of powder blended is 80% by weight.
When the amount increased (Comparative Example 7), the dispersibility in a shaking bottle and storage stability were poor, and the sensory experience was also poor.

Examples 10 to 18 Comparative Examples 8 and 9 (Aqueous foundation) Note) DPM in the table is dimethylpolysiloxane methyl (polyoxyethylene (10 mol)) siloxane polymer (1-4LSI et al.) (2) Manufacturing method After uniformly dissolving and dispersing the ingredients (1) to (2), put them into a specified aerosol container, and attach the specified valve 9 while degassing the upper air with a vacuum pump. Component [F] was then press-fitted and applied to each aqueous foundation.

(3) The above-mentioned tests were carried out on the water-based foundation resins, and their properties were investigated. The results are shown in Table 1. As shown in Table 1, the amount of propellant added is 1 to 3 with respect to the total weight of the composition.
It showed good shaking dispersibility, storage stability, and drying properties at 0% by weight.

However, if the content of the propellant is less than 1:4%, the propellant cannot be applied to the entire surface of the powder. Pickles, agglomeration of powder (
Caking) could not be prevented, and the long-term storage stability of the product was poor.

Example 14 (Acneosis tablet) (1) DMOE in the prescription table is dimethylpolysiloxane methyl (
Polyoxyethylene (20 moles), polyoxypropylene (20 moles), siloxane polymer (HshiBP,) (2) M-adjustment method After uniformly dissolving and dispersing the ingredients, place them in a designated aerosol container and vacuum. Install the specified valve while deaerating the upper air using a pump.

Next, components (1) and (2) were press-filled to prepare the acne scene.

(3) Characteristics The above-mentioned tests were conducted on the acne scars which were evaluated as '4', and the results of examining the characteristics are shown in Table 1. As shown in Table 1, the lotion exhibited good shaking dispersibility, storage stability, and practical properties. In particular, regarding practical properties, tests were conducted by selecting testers (20 people) who had acne.

As a result, when the lotion is squirted out of an aerosol container, the foam contains precipitated sulfur and has excellent performance when applied spot-on with fingertips to areas such as acne and pimples. It turns out.

As a result of continuous application for 8 weeks, 16 out of 20 people found that it had a healing effect on acne.
