Emulsions are the largest group of cosmetics among the cosmetic products. They consist of polar and non-polar phase and emulsifiers, which combine the two phases and maintain a uniform mixture. The emulsifier is a surfactant, containing in its molecule both hydrophilic and hydrophobic groups. One of the emulsifiers described in the article is a SLP of vegetable origin, forming emulsions O/W. It occurs in the form of a clear, yellow liquid with a fairly thick consistency. In cosmetics it is used in the production of lotions and preparations for the children. Another natural emulsifier, whose properties are known and used in cosmetics is the GMS of vegetable and animal origin. It belongs to the emulsifiers forming emulsions O/W. Aim. The aim was to test the quality of the self-prepared cosmetic emulsions. Materials and methods. Microscopic examination was performed on prepared cosmetic emulsions using a microscope with a magnification Jenamed 2 x 400, which was connected with an integrated camera sony ssc-dc 393P. Results. Photos of cosmetic emulsion droplets were measured twice. The measurement results have been summed and reached an average of two measurements. Conclusions. Comparing the results of measurements of the particle size of dispersed phase containing natural emulsifiers SLP and GMS, a dramatic decrease in the diameter of oil droplets in an emulsion with increasing mass fraction of emulsifier has been observed.
