Revitalization of clinical skills training at the University of the Western Cape.

Most educational institutions that offer health related qualifications make use of clinical skills laboratories. These spaces are generally used for the demonstration and assessment of clinical skills. The purpose of this paper is to share our experiences related to the revitalization of skills training by introducing the skills lab method at the School of Nursing (SoN), University of the Western Cape (UWC).

[Free formaldehyde determination in cosmetic products by the HPLC method].

In order to standardize the analytical methods and procedures with the ones used in the EU, a method of free formaldehyde determination in cosmetic products preserved with formaldehyde donors, recommended by Commission Directive (90/207/EEC of 4th April, 1990), has been tested. The free formaldehyde level is determined by HPLC using post column derivatisation with acetylacetone. Formaldehyde content was determined in 44 fortified samples of cosmetic emulsions and shampoos.

[Formaldehyde determination in shampoos, bath preparations and dish washing liquids by colorimetric methods].

In the years 1992-1993 in cooperation with Province Sanitary-Epidemiological Stations 2415 samples of shampoos and bath preparations for adults and children as well as of dish washing liquids, imported and produced in Poland, were analysed. The colorimetric method either with the chromotropic acid or acetylacetone was used. Among polish preparations, only in 6% samples of cosmetic products for children the level of formaldehyde exceeded permitted level of 50 mg/kg.

[Formaldehyde determination using the colorimetric method with acetylacetone. II. Formaldehyde determination in cosmetic emulsions and certain household products].

Total formaldehyde content was determined by the colorimetric method with acetylacetone in cosmetic emulsions and household products. The commercial products not containing formaldehyde were fortified with 150 micrograms of the investigated compound. Recovery in this method was 93.
