Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a variable color beauty pack agent, and more specifically, it is possible to visually tell when the dry backing agent will be removed after application of the pack agent by a change in color, and at the same time, This invention relates to a new beauty pack that sometimes gives an aesthetic sensation through color change.

The beauty packs that have been mainly used in the past can be divided into liquid, paste, powder, and oil packs depending on their shape. As time passes, the pack gradually dries as water and other volatile components evaporate, causing a feeling of contraction and tension on the skin. Peeling (
The applied pack agent was removed by washing, wiping it off, or rinsing, and the pack effect was obtained.

It goes without saying that the drying speed of such packs varies greatly depending on the shape and composition of the pack itself, as well as the ambient temperature at the time of the pack, and the feeling of shrinkage and tension in the skin, which is a guideline for drying the pack, also varies from person to person. Since there is a difference and it is not clear, it is necessary to rely on the person's personal touch, such as by touching it with their hands, to determine when the solid content of the pack will be released after the pack has dried. In particular, the mainstream pack agent at present is a beer-off type pack agent, and in such a pack agent, polyvinyl alcohol, polyvinylpyrrolidone, polyvinyl methyl cellulose, or vinyl acetate resin emulsion is used as a film forming agent. However, if an attempt is made to peel the film-forming agent while it is not sufficiently dried, the film will break and cannot be peeled off properly. As a result of intensive studies to improve this drawback, the inventor of the present invention found that by incorporating a pigment that changes color as the pack dries,
We have discovered and created a beauty pack that can visually detect the dry state of the applied pack and accurately determine when the solid content of the dry pack is released, and have completed the present invention. The purpose of the present invention is to provide a beauty pack that allows the user to accurately determine with the naked eye the timing of detachment of the dry backing agent after application, based on the color change.Another purpose of the present invention is to provide a beauty pack that allows the user to understand the aesthetic sense through the color change when using the pack. Our goal is to provide beauty packs that will help your skin.

That is, the present invention provides a beauty pack that dries and solidifies and contains one or more variable color substances that have different hues immediately after the pack is applied to the skin and after drying and solidifying. It is characterized by allowing

The pack agent according to the present invention can be applied to any pack agent that dries and solidifies after being applied to the skin, regardless of whether the pack agent is in the form of liquid, paste, or powder. All conventional pack base materials can be used.

That is, such pack base materials include, for example, fats and oils such as avocado oil, almond oil, olive oil, castor oil, palm oil, and coconut oil; waxes such as beeswax, mirror wax, lanonine, and microcrystalline wax; Hydrocarbons such as liquid paraffin, paraffin, ceresin, squalane, palmitic acid, stearic acid,
fatty acids such as oleic acid, alcohols such as ethanol, isopro/benol, octanol, cetanol, stearyl alcohol, oleyl alcohol,
For example, polyhydric alcohols such as glycerin, propylene glycol, and polyethylene glycol; esters such as isopropyl myristate, octyldodecyl myristate, butyl stearate, diethyl phthalate, and diptyl phthalate; polyoxyethylene phenyl ether, polyoxyethylene lanolin alcohol,
agents such as sorbitan monolaurylate, sodium lauryl sulfate, e.g. methyl parahydroxybenzoate, o-
Preservatives such as phenylphenol, salicylic acid, and sorbic acid; polymeric substances such as polyvinyl alcohol, vinyl acetate resins, methylcellulose, sodium carboxymethylcellulose, polyvinylpyrrolidone, and carboxyvinyl polymers; such as titanium oxide, zinc oxide,
Inorganic powders such as silicic anhydride, talc, kaolin, magnesium carbonate, and bentonite, and other base materials include color pigments such as organic or inorganic dyes and pigments, and various fragrances.

The styryl-like compound applied to the present invention can be incorporated into the pack agent by dissolving it in the solvents listed above, but as such solvents, oil-based base materials that are elutritable or immovable in water may be used. is preferred.

This is because in a pack prepared by dissolving the above-mentioned styryl-like compound in a water-soluble solvent, the discoloration of the pack after drying and solidifying on the skin may lack sharpness. The amount of the styryl-like compound contained in the pack agent according to the present invention is preferably 0.0001 to 0.1% by weight based on the amount of the pack agent.

That is, if the amount is less than 0.0001% by weight, the color change, which is a feature of the present invention, becomes difficult to clearly distinguish with the naked eye after the pack applied to the skin dries and solidifies. This is because even if it is used in excess of this weight percent, the cost of the pack will only increase, and in particular, no noticeable difference in color change will be observed. More preferably, 0.001 to 0
．． 01% by weight. The beauty pack according to the present invention includes:
Most of the styryl-like compounds applied to the present invention have light absorption in the ultraviolet region and are white (including cold colors) or pale yellow compounds. Immediately after being applied to the skin, the pack is white or pale yellow, but as it dries and hardens, it becomes blue, green, yellow, light, purple, red, etc. depending on the type of styryl-like compound used. The color develops vividly.

Such a color change is easily perceptible to the naked eye,
It is possible to clearly judge when the pack has dried and solidified based on the color change without being affected by the shape and composition of the pack itself or the ambient temperature at the time of the pack, so it is different from conventional packs. The dried pack agent can be removed by wiping it off, wiping it off, or rinsing it off at the appropriate time without relying on the user's personal touch. Such properties are particularly useful in beer-off type packs, which are currently the mainstream packs. Such a color change can be achieved by adding and containing an appropriate colored coloring material in the pack agent, and it is also possible to change the color from a certain color due to the coloring material to another color based on the coloring of styryl-like compounds. Possible depending on. In addition, such a color change can provide the user with an aesthetic sensation that has not been observed in conventional packs, and from this point of view it can be said to be a completely new beauty pack.
