Development of a cosmetic product for the face based on hyaluronic acid and honey

Abstract

We developed facial hydrating serum with the following composition of components (wt.%): hyaluronic acid 2.5, honey 4.5, alpha-hydroxy acids 1.5, propolis 0.5, chitosan 1.5 and bergamot hydrolate 89.5 (the bergamot content is 1–2%). The composition of the cosmetic was optimized using regression and sensory analysis. The effect of the concentrations of hyaluronic acid and honey on the kinematic viscosity of the solution was determined by the method of a full factorial experiment. Using the profile method of sensory analysis, the characteristics of serum consistency were evaluated according to such indicators as gel-likeness, homogeneity, turbidity and transparency. It was determined that the mixing of honey and hyaluronic acid in a ratio of 1.8:1 provides the required cosmetic effect and serum consistency. The moisture content of the facial skin of volunteers aged 20–60 was measured with a BBS-3000A cosmetology analyzer. After two weeks of using the developed moisturizer three times a day, it was recorded that the moisture content of the volunteers' facial skin increased to an average of 43%. According to the conducted quality control, when storage at temperatures of 5–250С for 12 months, the serum remains transparent, homogeneous without sediment, colloidal and thermally stable, pH=5.000.15. It was concluded that the face serum contains natural components that are safe for the skin, and contribute to intensive moisturizing and nutrition of the skin. It should be noted that the face serum is available in terms of components and economically beneficial. The technological scheme was proposed for the industrial production of the developed serum for the face.
