According to the general definition of cosmetic products, cosmetic products are any substance or mixture intended for application to various external parts of the human body (epidermis, hair, nails, lips, external genitalia), teeth, mucous membrane of the oral cavity exclusively or mainly for the purpose of their cleaning, aromatization, change of appearance, protection, preservation in satisfactory condition or correction of body odor;

The Technical Regulation of detergents states: “Detergent is any substance or preparation containing soap and/or other surface-active substances intended for washing or cleaning. Detergent can be in the form of liquid, powder, paste, bar, tile, tablet, etc.

P.4. The requirements of this Technical Regulation apply to:
• detergents intended for washing or cleaning and put into circulation on the territory of Ukraine for the needs of the consumer (user);
• detergents intended for soaking, rinsing, starching, dressing, softening or bleaching fabric products;
• detergents intended for cleaning surfaces, materials, products, mechanisms, mechanical devices, vehicles and auxiliary equipment, tools, equipment, etc.;
• other detergents intended for use during washing and cleaning.

P. 5. The requirements of this Technical Regulation do not apply to:
• solid soap;
• cosmetic products;
• surface-active substances that have disinfectant properties;
• detergents containing no more than 0.2 percent of surfactants.
Based on the above information: Liquid soap is identified precisely as a cosmetic product for its main purpose – exclusively for cleaning human skin and when applied directly to external skin areas, regardless of the content and percentage of surface-active substances, unlike a detergent intended for washing or cleaning of any surface if such treatment is necessary. Therefore, the Technical Regulation on detergents does not apply to cosmetic products, in particular liquid soaps.
