Abstract. The aim of this pedagogical practice is to develop pupils’ interest in natural sciences through participation in practical, creative, and socially significant activities. The project demonstrates how scientific knowledge in biology, chemistry and technology can be applied in the development of a real cosmetic product with high added value and safety. Delicate baby skin requires special care and products that minimize the risk of irritation and allergies. With increasing awareness of the harms of synthetic ingredients, interest in natural and edible formulas in baby cosmetics is growing.
The study presents the formulation of an innovative cosmetic washing product – baby shampoo, created entirely from safe edible ingredients. Natural surfactants (soap nuts and Sucrose cocoate) glycerin, prebiotic thickeners and food preservatives (potassium sorbate and sodium benzoate) were used. Each component was selected for its natural origin, low allergenicity and proven benefits for sensitive skin. The final product demonstrates good washing properties and a suitable viscosity texture, while eliminating the risk associated with potentially harmful chemicals and synthetic ingredients.
