Feminine hygiene products

Disposable polypropylene nonwoven fabrics are widely used as the coverstock for disposable baby diapers. The expansion of the disposable diaper market throughout the world has been the primary source of growth in the consumption of polypropylene in the fiber market. In addition, nonwoven polypropylene fabrics are used in a variety of other disposable sanitary products, such as baby wipes, adult incontinence, and feminine hygiene products. Use of polypropylene nonwovens in disposable medical apparel, such as surgical gowns, has increased as a means of reducing the spread of infection. 

Functional derivatives of polyethylene, particularly poly(vinyl alcohol) and poly(acryLic acid) and derivatives, have received attention because of their water-solubility and disposal iato the aqueous environment. Poly(vinyl alcohol) is used ia a wide variety of appHcations, including textiles, paper, plastic films, etc, and poly(acryLic acid) is widely used ia detergents as a builder, a super-absorbent for diapers and feminine hygiene products, for water treatment, ia thickeners, as pigment dispersant, etc (see Vinyl polymers, vinyl alcohol polymers). 

Poly(3-hydroxybutyrate—3-hydroxyvalerate) [80181 -31 -3] resin, produced from a bacterium during a sugar fermentation process, has been reported to be biodegradable, and its target markets include "flushables" such as feminine hygiene products and disposable diapers (99). 

Efficacy Decline in the amount of blood lost with menses (monitor a decline in the number of times feminine hygiene products such as pads and tampons require changing during menses) monitor for an increase in hemoglobin/hematocrit if anemia was present as a result of menorrhagia. 

Super slurper has wondrous properties, and it amazed people when it was first demonstrated. For some time no one seemed to know how to exploit its potential, then in 1968 chemists came up with the idea of incorporating polyacrylates into diapers, Here was a way to keep urine away from a baby s bottom and reduce diaper rash. The Japanese, always at the forefront of high-tech innovation, ate it up. Not literally, of course, but they could have — toxicity tests showed that the material was remarkably safe. By 1984 North Americans had also discovered the advantages of superabsorbent diapers, and the product rapidly dominated the market. Soon feminine hygiene products were also incorporating the new technology, as were adult incontinence products. 

Candida albicans, a yeast, and Trichomonas vagi-nalisis, a protozoa, can cause numerous health problems including vaginal infections, diaper rash, and thrush. The results below show that silver compositions of the present invention produced nearly a 100% kill of both organisms. The results show the utility of silver compositions of the present invention in a feminine hygiene product and in a diaper rash product. 

Potential applications for PHA include feminine hygiene products, packaging, appliances, electrical and electronics, consumer durables, agriculture and soil stabilisation, nonwovens, biomedical device adhesives, and automotive parts. 

Major applications for PL A fibres and non-wovens include clothing and furnishings such as drapes, upholstery and covers. Some interesting potential applications include household and industrial wipes, diapers, feminine hygiene products, disposable garments, and UV resistant fabrics for exterior use (awnings, ground covers). 

Nodax has the benefit of degradation in septic systems, which offer possibilities for application in feminine hygiene products such as wipes and tampon applicators. These flushable products may exist in the form of paper coatings, fibres, films and foams. 

Oligomeric agents were prepared by condensing trimethylolpropane with ethylene and/or propylene oxides and capping with acrylic acid. These materials were subsequently crosslinked using 2,2 -azobisamidinopropane dihydrochloride, which formed superabsorbent swellable hydrogel addition polymers and were useful as components in diapers or in feminine hygiene products. 

Personal care and hygiene Baby diapers, feminine hygiene products, adult incontinence items, dry and wet pads, nursing pads, nasal strips, etc. 

The first example can be found in disposable consumer products. In products which are designed for single-use, the shorter shelf-life of degradable polymers is not an issue. Especially in nappies, feminine hygiene products and wet wipes, biodegradable materials present interesting alternatives [169]. 

Although there are many uses of addition polymers, perhaps one of the most interesting applications is the use of sodium polyacrylate in superabsorbent diapers and some feminine hygiene products. The monomer for this polymer is sodium acrylate. This... 

In 2003, global demand for superabsorbents was 1.05 million tones and was found to increase at an average of 3.6% per annum. Out of the total demand, baby diapers account for about 81%, feminine hygiene products about 5%, adult incontinence about 8%, and other 6%. Other applications of superabsorbents are in removal of toxic heavy metal ions from industrial effluents, as drying agents, and removal of colloidal particles from potable water [106]. 

A novel superabsorbent polyacrylic acid/montmorillonite nanocomposite with an absorbency of about 1100 times its own weight has been made by Chinese scientists interested in the development of materials for use in babies nappies and feminine hygiene products. 

Nonwoven fabrics are used in several areas, probably the most well known being for the liners in disposable diapers. Similar fabric is also used in feminine hygiene products. At the other extreme, civil engineering fabric and tarpaulins are also produced from nonwoven fabrics. 

The porous superabsoibent polymers synthesized from cassava starch exhibited very fast water absorption properties and spongy texture (Figure 4.6). The water absorption capacity was found to be about 200 g/g and maximum absorbency was reached in 8-9 min. The fast swelling of SPHs in aqueous solution is due to the absorption of water by capillary forces through intercoimected pores. The fast-swelling property is a desirable characteristic in the development of personal-care products such as baby diapers, feminine hygiene products, athletic garments, and so forth.
