A deodorant is a substance applied to the body to prevent or mask (hide) body odor due to bacterial breakdown of perspiration in the armpits, groin, and feet, and in some cases vaginal secretions. A subclass of deodorants, called antiperspirants, prevents sweating itself, typically by blocking sweat glands. Antiperspirants are used on a wider range of body parts, at any place where sweat would be inconvenient or unsafe, since unwanted sweating can interfere with comfort, vision, and grip (due to slipping). Other types of deodorant allow sweating but prevent bacterial action on sweat, since human sweat only has a noticeable smell when it is decomposed by bacteria.

Treatment device

A treatment device having a first portion in a first plane, a treatment portion with a cover in a second plane that defines a treatment volume extending between the first and second planes, and a flexible transition portion that connects the first portion to the treatment portion. The treatment portion including a polymeric foam ring having interior and exterior walls extending from the first plane to the second plane. The cover spanning the interior wall thereby forming a closed treatment volume. The polymeric foam ring may be impregnated with a medicament selected from the group including an antibiotic material, an antifungal material, an antimicrobrial material, a deodorant material and nitric oxide. The cover may include a pocket for use with an accessory, such as a heater or mapping grid.
A method of treating a treatment area on a patient's skin with the treatment device. The treatment device includes a closed treatment volume having polymeric foam ring impregnated with a medicament. The treatment device is attached to the patient's skin, such that the closed treatment volume encloses the treatment area. The medicament is released into the treatment volume to bring the medicament into contact with the treatment area. Additional steps may include inserting a heater into the pocket or inserting the mapping grid into the pocket and tracking the treatment area with the mapping grid.

Process and apparatus for the production of a deodorant or antiperspirant composition

InactiveUS6338840B1Quicker and easy to control temperatureLess heat lossCosmetic preparationsToilet preparationsParticulatesActive agent
In a first aspect, a process for forming deodorant or antiperspirant sticks by continuously forming a mobile composition for dispensing into containers or molds at a rate matched with the rate at which it is dispensed, and in other aspects a process in which a mobile deodorant or antiperspirant composition is dispensed by injection molding, i.e. a process in which the deodorant or antiperspirant composition is dispensed under pressure. The composition at the time of injection moulding is preferably either in the vicinity of its regular set temperature, particularly in the range of about 0-3° C. below the regular set temperature and/or partially structured at the time of its delivery it into a container or mold. The deodorant or antiperspirant composition is preferably continuously produced in a screw extruder, especially a twin screw extruder, which is controlled to deliver the composition in a substantially semi-solid state, at a temperature close to its regular set temperature and is injected into the container or barrel at a pressure at the point of injection that is often greater than 15 psi. and in many instances from 200 to 400 psi in the injection head. Apparatus for forming deodorant or antiperspirant sticks by injection molding is also described. The combined process offers benefits for incorporating sensitive ingredients and ameliorating sedimentation of particulates such as particulate antiperspirant actives.

Antibacterial and environment-friendly deodorant of microorganism strains

The invention relates to an antibacterial and environment-friendly deodorant of microorganism strains and a preparation method thereof. The traditional method for removing odor generally uses essence to cover up the odor or pumping odor physically or uses ozone to oxidize and degrade the odor or uses a chemical method. The methods also can alleviate the odor to a certain extent, but finally the problem can not be solved really and fundamentally and the essence and chemical deodorization also have secondary pollution. The microbial deodorization technology utilizes the effects of high-efficient absorption, absorption and metabolism of particular microorganism strains which can convert or degrade odorant, to purify the odorous gases of amyl mercaptan, benzene methanethiol, methyl sulfide, ethanethiol, hydrogen sulfide, sulfur dioxide, p-benzyl mercaptan, ammonia, dimethylamine, trimethylamine and carbon disulfide and the like which are emitted from human life areas, domestic sewage and domestic garbage and the like and to convert the odorous components of amyl mercaptan, benzene methanethiol, methyl sulfide, ethanethiol, hydrogen sulfide, sulfur dioxide, p-benzyl mercaptan, ammonia, dimethylamine, trimethylamine and carbon disulfide and the like into matters without harm and odor, thus achieving the purpose of thoroughly improving air quality and protecting health of people. The preparation method utilizes a fermentation method of microorganism strains to prepare deodorant products.
