Karola Marcinkowskiego w Poznaniu Summary Introduction. Initially, individual substances acted as cosmetics. Most of them had natural origin. Sometimes their simple mixture was used. Today a cosmetologist has at its disposal thousands of simple and complex chemical individuals for use as a cosmetic raw material. Some of these substances are used particularly often, some compounds are undesirable and few of them are controversial. Knowledge of the most representative items of these groups should be widespread in order to use of cosmetics become more and more conscious choice. Aim. The aim of the study is to determine the frequency of major components in cosmetic care products, to estimate the exposure to individual components, and to provide targeted information to users of this type of formulation. Material and methods. A series of 300 products was grouped according to their form and purpose into 10 subgroups: day creams, night creams, day and night creams, eye creams, other skin care creams, gels, lotions, body creams, ampoules, masks and lotions. Random products were used to evaluate the composition of the preparations, commonly available in the shops of the Poznan and its surroundings. The list of ingredients provided by the manufacturers on the outer packaging of the products was analyzed. Results. The quality and quantity of the main components of the analyzed cosmetics declared by manufacturers were evaluated. It has been found that care products have a very rich qualitative composition. The number of substances used to make the cosmetic evaluation is in the range of 10-71. Most of the 300 tested cosmetics contain 33 to 40 ingredients. All formulations contain the most consistence-forming substances. Most preparations contain substances of natural origin. Very often it is one of the main ingredients of the care product. Conclusions. The cosmetic care composition usually consists of a large number of ingredients. Therefore, most of them have to be present in relatively small quantities. It has been shown that besides the commonly used water, the most common components in tested cosmetics are glycerol, glyceryl stearate, low molecular weight glycols and fatty alcohols. These chemicals should be the subject of extensive information about the properties of cosmetic ingredients.
