Tablet coating is carried out for the purposes such as decoration and protection of tablets along with some functional properties. The coating is a homogeneous mixture of polymeric material ; a very thin layer is applied on a substrate of the drug by using various techniques. These coatings techniques are either manually operated or fully automated. The automatic process gives coating with more uniform film properties at a high production rate. The coating is the last unit operation in the manufacturing of drugs in the pharmaceutical industries. Tablet coating involves the use of various binders, colour forming agents (colorants), organic solvents and plasticizers to get the required characteristics. Coating a tablet is always a great challenge to coating a formulator as it involves various statutory requirements to qualify as well as technically it also performs well against various environmental changes. Coating plays a key role in the pharma industry to protect the drugs from different environmental challenges like changes in humidity, light, heat etc. Now a days in coating application industries various new coating techniques are available like spray and fluidised bed methods that are developed to overcome the limitations of old techniques. This review paper focuses on the various aspects of various raw materials, types of tablet coating, processes of tablet coatings, defects and remedies of tablet coatings etc. Note de contenu : - PURPOSE OF COATING THE TABLET

Revêtements -- Séchage sous rayonnement ultravioletIndex. décimale : 667.9 Revêtements et enduits Résumé : Factory-applied exterior woodfinishes are often based on acrylic emulsions or polyurethane dispersions. UV curable PUDs were evaluated as alternatives. The best showed the required high flexibility combined with high surface hardness. Retention of wood colour in QUV testing was much better than that of the commercial clear coatings used as controls. Note de contenu : - Benefits and choice of UV cured coatings
- Chemistry of WB PUDS
- Limitations of traditional exterior wood coatings

Taches pigmentaires (dermatologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : The quest for means to get a beautiful skin is endless. However, defining what is beautiful partially depends on the geographical and ethnic origins of the persons. For instance, having a white skin is an extremely important element of the women's beauty in Asian culture. The desire for white skin originally cornes from traditional Asian values and beliefs. This desire has also been reinforced by Western influences (for instance Caucasian models are often used in adverts for European or American cosmetic brands sold in Asian countries). That is the reason why whitening/lightening products are among the best-selling products in the Asian cosmetic industry and are also becoming very important in Middle East, Africa and South America. In these areas, for many people, hyperpigmentation and skin pigmentary spots are not only considered as aesthetic problems, but they are also synonymous of decreased self-esteem, premature skin ageing and may facilitate the occurrence of skin damages, exacerbated by sun exposure. Conversely, Caucasians are looking to tan their skin since many consider tanning as a marker of a healthy lifestyle. But recent global consumer surveys on the primary cosmetic concerns of women have identified uneven skin tone and age spots as major concerns relative to signs of ageing. Trying to maintain or to regain a uniform skin tone, clear of age spots, is therefore a major and shared objective to consumers worldwide. Note de contenu : - Clinical study

- Skin lightening effect

The protection of the consumer from being misled by advertising claims of a cosmetic product is essential in the regulations. Misleading advertising in cosmetics may result from the use of only traces of certain ingredients whose efficacy is generally known to consumers and which are intensively advertised on the product, in the media or on the internet.En ligne : https://drive.google.com/file/d/1b-f5GuI6ZOVhl48bKfCTXVB0PQZC8eu0/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=36557
