Title : The use of tofu whey from food industry waste in the care of the scalp and hair
The aim of the study was to create cosmetic formulations used for washing and conditioning based on natural whey derived from tofu.Tofu whey used in the production of hair cosmetics turns out to be valuable waste that replaces water. Whey is an ingredient rich in proteins, oligosaccharides and isoflavones. When trying to follow the principles of sustainable development, we need also to be responsible for protecting water resources. Using whey, we limit water consumption to the necessary minimum. Hence, we also support no water waste trend. Tofu whey, which is a valuable waste that replaces water, was used in the production of masks and hair shampoos. The use of waste ingredients used in the production of tofu (whey) in cosmetics is called upcycling. The research was conducted following the approval of the Bioethics Committee, resolution number 223/22. Tests confirming or excluding the properties and performance of tofu whey declared by the Ordering Party were carried out at probands' homes and in the Dermatology Center (Centrum Dermatologii Sp. z o.o.) in Pozna?. The probands were volunteers. A group of 60 people was selected for the study according to the indications for the use of the product submitted for experiments. The selection of probands was carried out after a preliminary assessment of the condition of their hair, scalp and health. Due to the intended use of the product, the study involved people who declared their willingness to improve the appearance and condition of the scalp and hair. The study used the imaging method involving a trichological microcamera. On the basis of research carried out with the use of a scanning electron microscope (SEM) that enables observation of the topography of the tested hair, differences in its condition could be noticed.
