Abstract
Skin dysfunctions are a common problem. To restore and maintain skin functions, we modeled original semisolid hydrophobic systems from natural crude materials, using the experimental planning technique. The evaluation of the quality of the modeled systems according to the flow characteristics showed that the beeswax content in the systems affected their yield stress, consistency coefficient, and the flow behavior index, while the effect of cholesterol was slight. At temperatures of 40 and 50°C, the systems have pseudoplastic properties, while at 60°C – Newtonian. The evaluation of the viscoelasticity of the systems showed that the systems had elastic properties, and the most stable structure at different temperatures was demonstrated by formula VC6, containing: beeswax (5.828 g); solid paraffin (5.0 g); white vaseline (5.0 g); cocoa butter (10.0 g); cholesterol (3.0 g); and olive oil (70.0 g). Introduction of 0.5% liquorice root powder into the modeled base showed that this substance made the system thinner. The evaluation of the sensory properties of the bases showed that the characteristics of the VC6 system were most acceptable to the customer. Key words: Rheological characteristics, semisolid bases, beeswax.
