Determination of Dry Matter

If the contents of the cosmetic products used contain excess alkali, the skin is adversely affected. According to research in the field of dermatology, the skin of women with alkaline skin wrinkles more and more over time. Due to aging, the alkaline degree of the skin also increases. This is why the skin is dry, sensitized and sensitive to wrinkles.

As people become conscious, they try to protect themselves from the effects of chemicals, from food to inhaled air, even from makeup to skin care products. To be healthy, it is necessary to be selective in both nutrition and cosmetic products. Unfortunately, most cosmetics offered to consumers are of synthetic and toxic properties.

Human skin is the largest organ of the body and the cosmetic products applied on it are immediately absorbed by the skin and spread through the bloodstream. The harmful chemicals found in cosmetics sometimes irritate the skin, cause allergies, cause skin diseases, and worst of all can lead to cancer.

After evaporation of the water, the remaining part is dry matter. Acids and salts are water-soluble substances. The dry matter property of cosmetic products is also important in terms of keeping the stability and shelf life of the products long. It also shows the quality of the products.

Therefore, dry matter determination studies are carried out by authorized laboratories within the scope of physical and chemical analyzes. During these studies, on the one hand, the criteria and limitations set by the existing legal regulations and on the other hand, the standards published by domestic and foreign organizations are followed. Sartarious Method is the most commonly used method for determining the dry matter level of laboratory walls.

Laboratories for the determination of dry matter must be accredited by national or international accreditation bodies in accordance with the TS EN ISO / IEC 17025 General Requirements for the Competence of Testing and Calibration Laboratories.
