A too acidic or too alkaline medium in shampoo can, for example, lead to a disorder and cause scalp problems. Therefore, the pH value 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 the ingredients, then during the production process and finally in the finished shampoo application, gel / dye / foam that are on the shelves of the supermarkets. Here, it is necessary to fulfill the requirements and regulations of health organizations and GMP principles.
Many of us have experienced at least once that after a short while the pleasant smell of the foam worsens, even though in the beginning everything was fine. This is proof that the manufacturer made mistakes during the production process and perhaps did not pay enough attention to measuring and correcting the pH. The cosmetic product should not only be perfect on the day of its manufacture and meet the standard, it should also have a very good stability. Today, many hair and facial products are presented as "BIO". Manufacturers of such products need to remember that making such a product is much harder. The natural ingredients that make the product "BIO" can be quite capricious.
The pH and maintenance of the efficacy of cosmetics is one of the reasons why such products should be stored at certain temperatures. Some of them should not be refrigerated or exposed to direct sunlight and excessively warm temperatures.
