Summary of the invention
Talcum powder of the present invention (also can claim prickly-heat powder) to be the applicant Hu Shizhen through for many years concentrate on studies refining forming, it really can reach the effect of expection, can not only effectively prevent infant diaper rash, to tinea pedis, injure redness etc. outward control action also arranged, pounce in trick and can also avoid mosquito bite, process comprises that the trier's that relatives and friends wait use quite is subjected to favorable comment.
The inventor is to grasp the practical experience of research and development for many years because conventional talcum powder is not attained yet as for ideal, via test of many times, generation of the present invention is arranged.
The purpose of this invention is to provide a kind of talcum powder and manufacture method thereof with biocidal efficacies, described talcum powder comprises boric acid, Pulvis Talci, zinc oxide, magnesium carbonate, Cornstarch (native starch) etc., because compositions such as boric acid, zinc oxide have sterilization, suppress the characteristic of growth of microorganism, Cornstarch has cohesiveness, moisture absorption, dry and comfortable, lasting, the characteristic that is difficult for dispersing, and therefore the talcum powder of being made by above-mentioned composition has gentle sterilization, lasting, effect such as quality is good.
The specific embodiment
Below further describe function, prescription and the manufacture method of each composition of talcum powder of the present invention, so that every function, the characteristics of talcum powder of the present invention are had further understanding and understanding.
With reference to Fig. 1, talcum powder of the present invention roughly comprises boric acid 10, Pulvis Talci 20, zinc oxide 30, magnesium carbonate 40, Cornstarch (native starch) 50 etc., wherein:
(1) boric acid 10, and its amount is the 15-20% of talcum powder gross weight, are preferably approximately 18%, and its characteristic is, it is gentle disinfectant, can be used as the medicine of collyrium and washing wound, and medicated soap is also used boric acid, and the present invention also utilizes the antibacterial of boric acid as gentleness.And the security document of boric acid 10 is according to the data of Taiwan Industrial Technology Research Institute translation from the chemicals information laser disc (CCINFO) of Canadian occupational safety health center (CCOHS), the animal median lethal dose(LD 50) of boric acid is 3.5-4.1g/kg (LD50, mg/kg, eat, rat), promptly sucking by feeding or skin gives rat every kg body weight 3.5-4.1g, half death was arranged in 14 days, the effect that exposes to the open air of its skin in addition, do not have excitement for intact skin, damaged skin there is the moderate excitement, commonly used as the wound disinfection sterilization, but unlike other strong acid (example hydrochloric acid), stimulate.In the Tomes Plus laser disc that National Library of Medicine is published, also mention the sterilization idiocratic of available boric acid and make weather-proof timber, and avoid antibacterial effects such as paper products (cardboard etc.) are mouldy (referring to Tomes Plus, February calendar year 2001 version);
(2) Pulvis Talci 20, its amount is the 30-36% of talcum powder gross weight, be preferably about 35%, domestic present talcum powder roughly all uses Pulvis Talci, its composition characteristic is a magnesium silicate natural, that contain water, and price is low, and it also can be used as paper, pottery, plastic cement stabilizing agent and hardening agent, also there is filler to have the oil suction purposes concurrently, also comprises Pulvis Talci in the toothpaste composition as cosmetics;
(3) zinc oxide 30, its amount is the 32-38% of talcum powder gross weight, be preferably about 37%, its characteristic is, it is the white light grey powder of odorless, tool bitterness, it also often adds in ceramic tile, the glass with the filler purposes, can be used as growth of microorganism inhibitor and ointment filler (only limiting to external-applied ointment), also adds composition as moisture absorption, bacteriostatic at this talcum powder;
(4) magnesium carbonate 40, its amount is the 2-10% of talcum powder gross weight, be preferably about 4%, its key property is, it is lightweight white powder, nontoxic, incombustibility, be heat insulation and refractory substance, can be used for boiler insulation material, rubber-reinforced dose and pharmacy, dentifrice, the filler of cosmetics, antacid, and the desiccant of food; It is as the inserts of moisture absorption, dry composition in this talcum powder;
(5) Cornstarch 50, and its amount is the 3-10% of talcum powder gross weight, are preferably approximately 6%, and its characteristic is that cohesiveness is strong, are difficult for dispersing, lastingly.
In manufacture process all belong to dry powderedly owing to constitute the composition of this talcum powder, so manufacturing process should note the cooperation of environment, and humidity or aqueous vapor can not be arranged, the finished product of making its also store with.Manufacture method is as follows: (one) pours above-mentioned each composition in the sieve (or other alternative utensils) into according to ratio and shakes, and allows thinner part from sifting out, and with proper container it is packed into; (2) with clean hands (or other alternative utensils, as the flat wood lath or fill the mixing agitator tool automatically), the powder mixes in the container is stirred, until evenly.The composition safety of talcum powder of the present invention:
Talcum powder of the present invention is made by the composition combination of above proper proportion, the characteristic that wherein has sterilization, inhibition growth of microorganism owing to boric acid, zinc oxide, and Cornstarch has cohesiveness, lasting, the characteristic that is difficult for dispersing, therefore made talcum powder is compared with general talcum powder, has gentle sterilization, lasting, effect such as quality is good.And the various compositions that the present invention is contained, the skin that the HSDB (Hazardous Substances Data Bank, i.e. hazardous substance security document storehouse) that consults U.S. Tomes laser disc through consulting Industrial Technology Research Institute ring regulating the spleen and stomach heart professional investigates each composition contact human body there is no injury.
The above example of lifting for this case, this example is only established for explanation, and does not limit the scope of this case, and promptly various various changes within the scope of the appended claims all should be included in the claim of the present invention.
