PCE-228P pH meter for cosmetics |0.00 ... 14.00 pH|-1999 ... 0 ... 1999 mV (optional)|0.0...65.0 °C

The main task of cosmetics production is not just to make nice-smelling products with nice-sounding names and lists of beneficial ingredients, but to make them efficient, so that these products really improve the condition of the skin or hair and definitely don’t damage it PH measurement in cosmetics is a priority test that should be carried out not only to ensure the compliance of the pH of the product with the pH of the skin, but also to ensure good quality, appropriate viscosity, color / to ensure the smell and shelf life of the cosmetics.

A medium that is too acidic or too alkaline in e.g. shampoo, for example, can lead to a disorder and cause scalp problems. That is why the pH value in cosmetics is strictly and continuously monitored and not only in the end product! It is important to understand that monitoring is required at all stages: first in the raw materials and all the ingredients, then during the production process and finally in the finished shampoo, gel/dye/mousse... that can be found on supermarket shelves to be placed. Here it is important 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 everything was fine at first. This is proof that the manufacturer made mistakes during the production process and perhaps did not pay enough attention to pH measurement and correction.

The cosmetic product should not only be perfect and up to standard on the day of its manufacture, it should also have very good stability. Today, many hair and face products are presented as ”ORGANIC” - manufacturers of such products need to remember that it is much more difficult to produce such a product. The natural ingredients that make the product ”BIO” can be quite ”capricious” and their pH needs to be monitored very carefully. When talking about standard cosmetic products (both hair and skin), the ideal pH is between 4.5…5.5. Depending on the skin type for which the product is intended and also the function of the product (refers to chemical substances, hair dyes, strong hair and body sprays) the values can be lower and higher.

Using a pH meter with a special glass electrode is one of the well-known methods of measuring pH in cosmetics. The pH meter ensures that you get reliable results when measuring in shampoo, liquid cleaning 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 use. On the one hand, the glass electrode is perfect for the application because it is always easy to keep clean, but on the other hand, a glass electrode requires careful handling because of its fragility. Modern electrodes receive special protection, like ””a coat”” 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 carried out on the additives or finished products such as shampoo, it is imperative to maintain the required ambient temperature, as its deviation can lead to erroneous measurements. pH and maintaining the potency of cosmetics is one of the reasons why such products should be stored at certain temperatures. Some of them should be kept in the refrigerator or exposed to direct sunlight and excessively warm temperatures.
