PCE-PH20P PH Tester for Cosmetics (Pastes)|0.01 pH |Data-Hold| Calibration pH 4, 7, 10 (automatic)

The main task of cosmetics production is not only to make good-smelling products with good-sounding names and lists of useful ingredients, but to make them efficient so that these products really improve the condition of the skin or hair and do not damage them in any case. The pH measurement in cosmetics is a test of priority, which should be carried out not only to ensure the correspondence of the pH of the product with the pH of the skin, but also to ensure good quality, suitable viscosity, color / odor and shelf life of cosmetics.

For example, a medium that is too acidic or too alkaline in shampoo can cause a disorder and cause scalp problems. Therefore, pH in cosmetics is strictly and continuously monitored and not only in the final product! It is important to understand that monitoring is required at all stages: first in the raw materials and all ingredients, then during the production process and finally in the finished shampoo oo, gel / dye / foam ... that are placed on the shelves of supermarkets. Here it is necessary to meet the requirements and regulations of health organizations and GMP principles! Many of us have experienced at least once that after a short time the pleasant smell of the foam worsens, although at the beginning everything was fine. This is the evidence that the manufacturer made mistakes during the production process and perhaps did not pay enough attention to the measurement and correction of pH. The cosmetic product should not only be perfect and meet the standard on the day of its production, it should also have a very good stability. Nowadays, many hair and face products are presented as ”BIO” - manufacturers of such products must remember that it is much more difficult to make such a product.

The natural ingredients that make the product ”BIO” can be quite ”capricious” and their pH must be monitored very closely. If we talk about standard cosmetic products (both hair and skin), the ideal pH is between 4.5 ... 5.5. Depending on the type of skin for which the product is intended and also on the function of the product (refers to chemical substances, hair dyes, strong hair and body sprays), the values can be lower and higher. The use of a pH meter with a special glass electrode is one of the commonly known methods of pH measurement in cosmetics.

The pH meter ensures that you get reliable results when measuring in shampoo, liquid cleansing toners and foams, gels and many other substances (containing water!). pH meters used for cosmetics are often portable, very easy to use, light in weight and convenient to handle. On the one hand, the glass electrode is perfect for use because it is always easy to keep clean, but on the other hand, a glass electrode requires careful handling because of due to its fragility. Modern electrodes get a special protection, like ”a sheath” around them, which makes them very robust. The application of the pH electrode requires attention and careful adjustment. It is necessary to follow all the rules regarding the use, cleaning and maintenance of this delicate instrument. Although the pH tests are performed on the additives or finished products, such as in the case of shampoo, it is imperative to maintain the required ambient temperature, as its deviation can lead to erroneous measurements.

The pH and maintaining the effectiveness of cosmetics is one of the reasons why such products should be stored under certain temperatures. Some of them should be stored in the refrigerator or exposed to direct sunlight and excessively warm temperatures.
