Determination of Content and Chemical Characterization of Cosmetic Products
Physico-chemical tests performed to determine the content and chemical characterization of cosmetic products are used to characterize the properties, detect the behavior in the formulation and measure the performance of the components under real use conditions. These operations, performed in the early stages of the development of a new component, are necessary to optimize the component's structure or adjust its composition to the functionality and behavior expected by end product users.

From simple regular monitoring of pH value, viscosity, temperature stability or post-centrifugation of cosmetic products to techniques such as light backscattering, a combination of physico-chemical measurements are used to observe how ingredients affect the stability and strength of a formulation.
Techniques such as optical or electron microscopy, laser particle size, or dynamic light scattering are used to control the role of an emulsifier on the homogeneity and particle size of an emulsion. These techniques help verify the correct distribution of the ingredients, such as the correct dissolution or dispersion of the active ingredient within the formulation.
Physico-chemical tests are often the first step towards measuring the performance of an excipient. A number of techniques are used, selected according to the functionality of the materials and the desired activity.
Although each product's formula varies slightly, most cosmetics contain a combination of at least some of these essential ingredients: water, emulsifiers, preservatives, thickeners, emollients, coloring agents, fragrances, and pH stabilizers.
- Water forms the basis of almost every type of cosmetic product, including creams, lotions, makeup, deodorants, shampoos and conditioners. However, this water must be ultrapure, meaning it must be free of germs, toxins and other contaminants.
- Emulsifiers are any ingredients that help prevent different substances, such as oil and water, from separating. Many cosmetic products are based on emulsions, that is, small droplets of oil dispersed in water or small droplets of water dispersed in oil. Since oil and water do not mix with shaking, emulsifiers are added to change the surface tension between water and oil and a homogeneous and well-mixed product is obtained.
- Preservatives are important ingredients. It is added to cosmetic products to extend their shelf life and prevent the growth of microorganisms such as bacteria and fungi that could spoil the product and possibly harm the user. Since most microbes live in water, the preservatives used must be water-soluble. Preservatives used in cosmetics can be natural or synthetic and perform differently depending on the formulation of the product.
- Thickeners (thickeners) are used to give products an attractive consistency. These can come from four different chemical families: lipid thickeners, naturally derived thickeners, mineral thickeners, and synthetic thickeners.
- Emollients soften the skin by preventing water loss. They are used in a wide variety of lipsticks, lotions and cosmetics. A number of different natural and synthetic chemicals are used as emollients, including beeswax, olive oil, coconut oil, lanolin, petroleum jelly, mineral oil and glycerin.
- coloring substances (pigments) are used in cosmetic products to highlight or change a person's natural color. Mineral components include iron oxide, mica flakes, manganese, chromium oxide and coal tar.
- Fragrances are used to make the cosmetic product have an impressive scent. Research shows that scent is one of the key factors in a consumer's decision to purchase or use a product. Both natural and synthetic chemicals are added to cosmetics to provide an attractive scent.
- pH stabilizers are used to ensure that the cosmetic product maintains the skin's natural pH level. The skin has a certain pH level. When this pH level is disrupted, some disorders occur on the skin, such as discoloration, acne or thinning of the skin barrier.
