شیمی ضروری برای فرموله‌کنندگان دوزهای نیمه‌جامد و مایع

A needed resource for pharmaceutical scientists and cosmetic chemists, __Essential Chemistry for Formulators of Semisolid and Liquid Dosages__ provides insight into the basic chemistry of mixing different phases and test methods for the stability study of nonsolid formulations. The book covers foundational surface/colloid chemistry, which forms the necessary background for making emulsions, suspensions, solutions, and nano drug delivery systems, and the chemistry of mixing, which is critical for further formulation of drug delivery systems into semisolid (gels, creams, lotions, and ointments) or liquid final dosages. Expanding on these foundational principles, this useful guide explores stability testing methods, such as particle size, rheological/viscosity, microscopy, and chemical, and closes with a valuable discussion of regulatory issues. __Essential Chemistry for Formulators of Semisolid and Liquid Dosages__ offers scientists and students the foundation and practical guidance to make and analyze semisolid and liquid formulations.* Unique coverage of the underlying chemistry that makes possible stable dosages * Quality content written by experienced experts from the drug development industry * Valuable information for academic and industrial scientists developing topical and liquid dosage formulations for pharmaceutical as well as skin care and cosmetic products A needed resource for pharmaceutical scientists and cosmetic chemists, Essential Chemistry for Formulators of Semisolid and Liquid Dosages provides insight into the basic chemistry of mixing different phases and test methods for the stability study of nonsolid formulations.
