DEVELOPMENT OF THE COMPOSITION AND TECHNOLOGY OF CREAM BASED ON
PHYSICAL FILTERS
Baratova M.B., Rizaeva N.M., Aripova N.Kh.
At present, solar radiation, especially its short-wave ultraviolet part, is one of the
most powerful environmental factors that determine the conditions for the
development and existence of all life on the globe, including humans, and largely
characterizes the climate [1].
In modern cosmetics, zinc oxide is used as physical filters. They can also be found
under the name mineral filters. They are mainly used in micronized, ultra-micronized,
micronized and nanoparticulate form. This allows them to be added to creams in greater
quantities to ensure a high SPF index, while leaving no white marks on the skin.
A small amount of solar ultraviolet radiation is good for human health. An
excessive amount of sunlight can cause incomparable harm. The sun's ultraviolet light
causes premature aging of the skin (from age 35), it breaks down collagen and causes
skin hyperpigmentation, and by the age of 45, 90 percent of wrinkles are caused by UV
exposure. Especially in summer, in our climate, the effect of ultraviolet radiation is
enhanced [2]. Taking into account the above, the current issue is to expand the range of
sunscreens.
Purpose of the study. To develop the composition and technology of sunscreen.
Materials and methods. The materials for the study were hydrophobic bases and
a hydrophilic base. Based on the requirements, the following three types of
compositions are proposed in Table 1.
All of these compositions were studied for their physicochemical properties:
appearance, color, odor, pH, colloidal stability, thermal stability, spread ability
according to generally known methods [3].
Results: As can be seen from Table 2, only formulation I meets all the studied
quality indicators: appearance, color, odor, pH, colloidal stability, thermal stability and
spreadability. Formulation II did not correspond to colloidal stability, and formulation
III did not correspond to thermal stability.

Conclusions. Thus, the studies carried out have shown that the most optimal and
effective sunscreen that meets the basic requirements for the quality of creams turned
out to be a cream prepared according to formulation I.
