Personal hygiene applications

In recent years breathable PE film for personal hygiene applications has been developed. Traditional backsheet nappy film of LDPE is increasingly replaced by LLDPE film grade. This breathable film is usually manufactured from chalk compounds based on LLDPE or metallocene LLDPE. After extrusion, the films are subjected to stretching in order to introduce microperforations into the film at the interface between the polymer and the chalk particles. 

The sole objective of all hygiene and manufacturing controls is to ensure the quality of the pharmaceuhcal product for the safety and protection of the pahent. The manufacture of non-sterile pharmaceutical products requires that certain criteria of cleanliness, personal hygiene, produchon methods and storage must be met. Many such products are for oral and topical use and the question may fairly be posed as to the point of what are now quite stringent conditions. Nevertheless, some carefully controlled hospital studies have indeed shown that both types of medicine may be associated with nosocomial (hospital-acquired) infections and this risk can be minimized by the application of GMP principles. 

Table V summarizes the results of analyses for 2,k,5-T in the 2U-hour urine samples. Urinary levels ranged from <0.01 ppm for an observer to IT ppm in urine collected from applicator it who was wearing the leaking backpack sprayer. Proper maintenance of equipment and better personal hygiene probably could have prevented the relatively high exposure experienced by this individual, estimated as a dose of about 0.2 mg/kg of body weight.

Animals Isolate infected animals. Limit vector access to animals through application of pesticides. Ensure adequate personal hygiene of anyone coming into contact with the animals. Consult veterinarian familiar with possible exotic diseases. 

Personal hygiene products such as disposable diapers make use of self-adhesive strips, covered with a release tape that is removed at the point of use. Again unmodified acrylic dispersions as well as hot melts dominate this application. The same considerations apply here as in first-aid dressings, and in particular the adhesive must not cause skin irritation. 

Films that are used in disposable applications including, e.g., personal hygiene, should be highly permeable to water vapor and should exhibit a good softness. The permeability to water vapor is sometimes referred to breathability... 

Household and personal hygiene products comprise another group of samples that can be screened and examined for volatile components. Thus, 1,4-dioxane in shampoos, ethylene oxide in cosmetics, and fragrances in soaps and cleaning fluids are examples of typical applications of the technique. 

There has been a move from conventional granular gel materials to foamed (198) and flat plate (199) type superabsorbents based on poly(acrylic acid). In addition to superabsorbents for personal hygiene, the materials have wide ranging applications in many areas from biomedical to cosmetics. Some of these are petroleum recovery and sealing of sewer pipes when cross-linked with metals such as iron salts (200) flocculants in water purification (201) copolymers with...
