Cosmetic tissues

Because of the extraordinary supramolecular structure and exceptional product characteristics as high-molecular and high-crystalline cellulosics with a water content up to 99%, nanocelluloses require increasing attention. This review assembles the current knowledge in research, development, and application in the field of nanocelluloses through examples. The topics combine selected results on nanocelluloses from bacteria and wood as well as their use as technical membranes and composites with the first longtime study of cellulosics in the animal body for the development of medical devices such as artificial blood vessels, and the application of bacterial nanocellulose as animal wound dressings and cosmetic tissues. 

CDDs (TCDD, PeCDD, HxCDD, HpCDD, and OCDD) are also present in newsprint, facial (cosmetic) tissue, and recycled paper at levels ranging from <0.4 to 335 ppt (Beck et al. 1988b). OCDD was the most abundant congener detected in newsprint (37 ppt). HxCDD was the most abundant homologue detected in cosmetic tissue (79 ppt) and recycled paper (335 ppt). 2,3,7,8-TCDD was found at lower...

Shikonin [517-89-5] (Cl 75535) occurs as an acetyl derivative in the Japanese shikone, Uthospermum eTythrorhi n another member of the Boraginaceae family. It is the (R)-optical isomer of alkannin (66). Tissue cultures of E. eythrorhi n are used in Japan to manufacture shikonin mainly for cosmetic use (67). Both alkannin and shikonin are mordant dyes producing violet to gray colors on fabrics. In Japan, shikonin was used to dye fabrics a color known as Tokyo Violet. Shikalkin [54952-43-1] the racemate (11), has been synthesized (68). 

The ocular irritation caused by cosmetic ingredients has been evaluated by the determination of the amount of histamine contained in tears. Contact of surfactants and the eye tissue cause an immediate dose-dependent release of histamine through direct cytotoxic damage of cell membranes. This method has been tested with sodium lauryl sulfate with volunteers [187]. 

Highly purified hyaluronic acid, useful in medicine and cosmetic areas, has been prepared from body tissues by different treatments with the help of sodium dodecyl sulfate [199]. 

Exposure of women to cosmetic talcum powder, has been related to the observed presence of the characteristic phyUosilicate talc particles in normal and in malignant ovary tissue (Henderson etal., 1979). The experimental demonstration in rats of migration of talc particles from the vagina to the ovary, illustrates the potential route of entry into the body (Henderson etal., 1986). 

The primary goals of therapy for skin cancer are to completely eradicate the tumor and minimize the risk of tumor recurrence and metastasis. Secondary goals of therapy include preserving normal tissue, maintaining function, and providing optimal cosmetic outcomes.5... 

In order to answer questions regarding the therapeutic and cosmetic uses of the myriad dermatological concoctions available, a pharmacist must be knowledgeable about the anatomical structure and physiological functions of the skin and the chemical compositions and physicochemical properties of its constituent tissues. Some understanding of how its properties are affected by disease and damage is a must, as is... 

Breast-conserving therapy (BCT) is appropriate primary therapy for most women with stage I and II disease it is preferable to modified radical mastectomy because it produces equivalent survival rates with cosmetically superior results. BCT consists of lumpectomy (i.e., excision of the primary tumor and adjacent breast tissue) followed by radiation therapy (RT) to prevent local recurrence.
