ABSTRACT
With the aim of making a contribution to the phœnicicultural sector in Morocco’s eastern region, a cream and soap trial was carried out incorporating date kernel oil in the form of waste products, to produce a moisturizing cream and a foaming soap. First, the physicochemical parameters are determined. The weight of the kernel is 0.4 g and 2.9 g, with an average fat content of 11% (dry matter). On the other hand, it allows us to know the water contents, these results are 2.313% - 4.562%; the mineral elements of fresh matter, we have in cadmium: 0.0122 - 0.0775 ppm, in zinc: 0.896 - 2.1946 ppm, in cobalt: 0.0272 ppm, in lead: 0.5086 - 0.5123 ppm, in copper: 0.478 - 0.3766 ppm, nickel: 0.2348 - 0.0736, iron: 1.7424 - 2.1484 ppm, chromium: 0.214 - 0.2368 ppm, nitrate ions: 3.333 - 8.555 µM/ml, nitrite ions: 19.071 - 20.357 µM/ml, phosphate ions: 7.074 - 8.888 µM/ml, sulfate ions: 20.714 - 30.714 µM/ml. In order to gain a better understanding of the formulation for a cream and a soap, the extracted oil is incorporated with argan oil, shea butter for the cream. For the soaps, hot and cold saponification methods were used with argan oil, shea butter, and soda. These results show that date pits can be put to good use in the cosmetics sector, where they add considerable value.
