Each of the measured rates shows constant at first and gradually becomes small in all cases. In this paper, we discuss the behavior of drug release in constant rate region. The rate of release was found to be controlled by both the viscosity of oil vehicle and the partition coefficient of drug between oil vehicle and receptor phases. All oil vehicle-drug systems studied have small deviation between experimental rate and calculated one which is determined by both factors, viscosity and coefficient.View full abstractDownload PDF (1069K) -

The system consists of the measurement of 13C-NMR spectrum of an unknown mixture and of subsequent computer analysis of the spectrum.
Despite the facts that hair dye products are usually composed of both large amounts of various surfactants and small quantities of labile oxidizing dyes susceptible to air and that the foundations being diverse in formulation, on the other hand, contain a lot of inorganic pigments which are not amenable to CMR, analytical results on organic components in these cosmetic products were found satisfactory, thereby indicating, when our earlier work is taken into account, that this system would be successfully applicable to composition analyses of a variety of organic mixtures as well as cosmetics.View full abstractDownload PDF (744K) -

DOIhttps://njjn-jsjc-gov-cn-s-1416.res.gxlib.org.cn:443/rwt/1416/https/MSYXTLUQPJUB/10.5107/sccj.23.126JOURNAL FREE ACCESSThe effect of the alkyl chain length of fatty acid soaps (C12-C18) and the other type of surfactants using for cleansing foams on adsorption on skin and on selective cleaning ability have been studied. It has been also examined whether there is any relationship between the adsorption volume of the surfactants, selective cleaning ability and skin condition.
Squalene and cholesterol were used as indicator of the selective cleaning. The selective cleaning ability of the surfactants has been obtained from the wash-off ratio of cholesterol/squalene +cholesterol. Potassium palmitate and potassium stearate indicated to have higher wash-off ratio than other surfactants and had the selective cleaning ability. Besides these surfactants did not adsorb on skin. Moreover in an users' test of cleansing foams, the skin condition applied the sample including palmitic acid and stearic acid was better than that of another sample.
In conclusion, it has been suggested that the surfactants which do not adsorb on skin and have selective cleaning ability maintain the skin condition to be good.View full abstractDownload PDF (1073K) -

DOIhttps://njjn-jsjc-gov-cn-s-1416.res.gxlib.org.cn:443/rwt/1416/https/MSYXTLUQPJUB/10.5107/sccj.23.134JOURNAL FREE ACCESSTo provide a basis for designing more effective makeup preparations, the optical effects of mixing two colored foundations, consisting of Color-corrective Foundation (A) and Regular Foundation (B) was investigated. Attempts were made to prove the effectiveness of Foundation A through a prediction of complexion tone when both foundations were applid. In this study, a novel theory on modification of skin complexion was proposed. The application of the theory requires two factors: (1) Formation of non-mixing two-layered film, consisting of Film A and Film B on the skin and (2) Assigning of separate functions for each films, i.e., Film A primary for hinding imperfections, and film B primary for rendering color. Foundations optimizing these factors have been prepared and found to modify skin complexion much more effectively than conventional foundations.View full abstractDownload PDF (3231K)
