JPS58144315A - Plaster for remedying corneum - Google Patents

Abstract

PURPOSE:Plaster for remedying corneum such as a corn, a callosity, etc., applicable to the affected part in a good adhesion state for a relatively long time, showing the maximum medicinal effect, and yet having no side effect, obtained by blending salicyclic acid with starch having adhesivity. CONSTITUTION:Salicyclic acid having effects to soften keratin without causing ache as a base for an active ingredient is blended with starch with a proper amount of water, having adhesivity, to give plaster for remedying corneum. The plaster can be prepared extremely easily, has no irritation to the affected part or its surrounding parts, and yet having sterilizing power and effect to soften the corneum and to remove it quickly, showing the highest medicinal effect because it covers the affected part well as it is bonded to it. Consequently, resection of the cornum as it is carried out in a conventional procedure is not required and remedying effect can be shown only by its application in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a drug to be used for those with a stratum corneum formed on the skin, such as corns and corns, and is a liniment containing salicylic acid as a Rh component, which has a relatively long and good effect on diseased areas. The present invention relates to a coating agent that is resistant to adhesion in a sticky state and has effective medicinal effects.

So-called "calluses" and "corns" occur when the skin in those areas becomes keratinized due to physical and mechanical stimulation from the outside, but "calluses" in particular In response to these stimuli, the skin hardens and thickens upward from the surface of the skin, becoming hard, flat, and often yellow in color, the size of a pea.

On the other hand, "fish eyes" are caused by physical damage from the outside, similar to "octopuses".
It is caused by receiving mechanical stimulation,
The hardening and thickening of the skin is reversed and occurs downwards in a round shape, so when viewed from the surface it is hard and a core is formed at the thickened center, and the lower end of the core stimulates the nerves. It causes pain.

These conventionally described treatments include, for example,
First, scrape off the stratum corneum of the skin with scissors, etc., and then
Subir plaster is applied and a bandage is firmly applied over it to fix it in place, and after 4 to 5 days, the white, softened skin is scraped off with a safety razor, a scalpel or Cooper's scissors. (Published by Social Insurance Publishing Co., Ltd. “Zenka Family Medicine No. 648”
However, forcibly cutting the stratum corneum as described above is undesirable because it causes bleeding and inflammation of the skin due to fungi.

The present invention focuses on the previously known effect of salicylic acid, which is the effect of softening keratin without causing pain, and by mixing starch containing an appropriate amount of water with a modified material of salicylic acid, it can be formed extremely easily. The present invention has completed a liniment for calluses, etc., which adheres well to the affected area with its adhesive properties and has no side effects.

We are still collecting information on the effectiveness of this liniment, but it appears that the stratum corneum will be reduced to a minimum within 4 to 5 days of application.

(Properties) The obtained liniment has salicylic acid mixed into a harmless starch containing an appropriate amount of moisture, and when applied to the skin surface, it covers the diseased area with good adhesion.

(Product) This sticky coating agent may be bottled or otherwise made into a product, and in this case, known active ingredients such as ichthyol zincated oil and nisitylol may be added.

Salicylic acid powder is mixed with hot water and starch in a predetermined container, and the mixture is stirred to obtain a sticky base material.

The liniment thus obtained is not irritating to the diseased area or its surrounding areas, has bactericidal activity and the effect of quickly softening and removing the stratum corneum, and is effective against diseases. Because it coats the skin properly and adheres well, it maximizes its medicinal effects.

Therefore, the treatment can be effective in a short period of time simply by applying it without scraping off the stratum corneum as in the past.
