ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cosmetic composition containing charcoal as a main ingredient and a method for its manufacture. More particularly, the present invention relates to an improved cosmetic composition containing charcoal which has an excellent adsorptive capacity for treating the skin and removing waste materials such as sebum, old corneous tissue or dust disposed on the skin.
2. Description of the Related Art
Various types of cosmetic compositions and methods for the preparation thereof are known in the art. Generally, the human skin is covered with skin oil, sweat, dust, old corneous tissue and cosmetic residue. Also, pimples develop on the human face in the summer months or at puberty and frequently sebhorreic dermatitis is produced from such pimples. Therefore, in order to clean the skin surface, a number of cosmetics have been developed. However, these conventional cosmetics do not provide the desired excellent improvement in the beauty treatment of the skin.
Even though charcoal has been utilized in cosmetic soaps, at the present time, such charcoal functions as a kind of abrasive cleanser. Therefore, charcoal has never been used in a cosmetic composition as a main ingredient for treating the skin in a beauty sense since the black coloration of the charcoal was thought to block an improvement in the beauty treatment of the skin. Thus, when conventional cosmetic soap containing charcoal is manufactured, there is the disadvantageous that the manufacturer must always keep in mind that the color of charcoal may adversely affect the skin.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an improved cosmetic composition containing charcoal as a main ingredient and a process for the preparation thereof which eliminates the above problems encountered with conventional cosmetic compositions and method for the preparation thereof.
Another object of the present invention is to provide a cosmetic composition containing charcoal as a main ingredient plus suitable amounts of a moisture agent, an additive agent, an oil, a preservative, an alcohol, a perfume and emulsifying agent for improving the beauty treatment of the skin and preventing the formation of black color on the skin.
A further object of the present invention is to provide a cosmetic composition containing charcoal for preparing various types of beauty treatments such as the peel-off type, the wash-off type, the sheet type pack and the cleansing cream and massage cream gel types so as to improve the removal of waste materials from the skin and provide an excellent non-harmful cosmetic effect for beautifying the skin.
Still another object of the present invention is to provide a method for the preparation of an excellent cosmetic composition from the charcoal as a main ingredient.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
Briefly described, the present invention is directed to a cosmetic composition containing charcoal which is present in an amount of 0.1 to 50 parts by weight, preferably 5 to 20 parts by weight, and having a particle size of about 200 to 500 mesh and to a process for the preparation thereof, for improving the beauty treatment of the skin which includes the removal of waste materials on the skin.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention pertains to a cosmetic composition containing charcoal and a process for the preparation thereof. Particularly, the cosmetic composition of the present invention comprises 0.1-50 parts by weight of charcoal such as medicated charcoal, activated charcoal, etc. having a particle size of about 200 to 500 mesh improving the beauty treatment of the skin including the removal of waste materials such as skin oil, old corneous tissue or dust from the skin.
The charcoal having a particle size of 200 to 500 mesh includes charcoal having a plurality of pores having various types of pores for increasing the adsorptive capacity of the charcoal which, in turn, improves the adsorptive ability and moisture possessing ability of the cosmetic composition containing the charcoal. Also, medicated and activated charcoals are not harmful to the human body, and this provides an excellent cleansing effect for the skin.
The cosmetic composition containing charcoal can be used in various types of preparations, such as packs of a wash-off type, a peel-off type, and a sheet type, cleansing creams, massaging creams, and bath gels for preventing coloration from the charcoal on the skin.
The process for the preparation of the cosmetic composition containing charcoal as a main ingredient according to the present invention comprises dissolving and mixing about 50 to 99.9 parts by weight of suitable cosmetic agents at room temperature or an elevated temperature, and adding about 0.1 to 50 parts by weight of charcoal and emulsifying the mixture to prepare the various types of preparations as described in detail hereinafter. The charcoal is made from Korean pine tree, oak tree and bamboo and can be utilized as white charcoal and black charcoal and preferably medicinal charcoal and activated charcoal.
