Cosmetic Analysis

From the ancient Egypt to the present, it is seen that people used vegetable oils for treatment purposes and obtained perfume from them. The essence of the eastern world on the fragrances and fragrances is indisputable. It is known that medicinal baths, spas and mud baths are used from ancient Egypt to the Romans. Today, spa water is used in many creams and skin care. Minerals in the waters of the spa provide health and beauty from ancient times to today.

Today the cosmetic product is defined as preparations that cleanses, moisturizes, nourishes, protects and gives a pleasant smell by acting on the upper surface of the skin.

The Cosmetic Law issued in 2005 discloses the principles for notifying these products before they are placed on the market, conducting market surveillance and inspections, and inspecting the places that produce these products in order to ensure that the cosmetic products reach people in a quality, safe and effective manner. The application area of ​​this law is determined as follows: the body of the human body, nails, hair, hair, lips and external genital organs with different parts of the teeth and oral mucosa prepared for application and clear these parts, smell, change the appearance, correct body odors, ingredients used to protect and keep in a good condition.

The Cosmetic Regulation, which was later issued, aimed at ensuring that cosmetic products could reach the consumers with accurate and understandable information that would not lead to human error and would not harm human health. In this context, the regulation sets out the principles for the measures to be taken at the end of the inspections, inspections, market launches, market surveillance and inspections, technical information, cosmetic products must have.

To better understand the testing, measurement and analysis studies carried out by the authorized laboratories, one should also look at how the cosmetics are classified. Cosmetics are mainly classified in two ways according to their application areas and basic domains. According to the place of application, cosmetics, cosmetic preparations applied to the skin, powders and pigmented preparations, cosmetic preparations applied to the hair, cosmetic preparations applied to the teeth and oral cavity and other cosmetic preparations are separated.

The main raw materials used in the production of cosmetics are: vegetable oils, animal fats and fatty substances, mineral oils and fatty substances, fatty acids, fatty alcohols, water and powders. Alkaline and ammonium salts of fatty acids, fatty alcohol, sulfuric acid esters, phosphoric acid esters, moisturizers, antioxidants, solvent suppliers, fragrances, dyes and pigments are used.

Although cosmetic substances are used for skin health and aesthetic purposes, some undesirable conditions occur during application. For example, irritation, allergic effects, photosensitivity, pigmentation, and changes in hair and nails.

Therefore, testing and analysis of cosmetic products is very important. Tests and analyzes carried out by laboratories accredited by national and international accreditation bodies in accordance with the TS EN ISO / IEC 17025 Standard for the Qualification of Test and Calibration Laboratories can be grouped as follows:

  • Physical and chemical analyzes
