The invention relates to a method of making a solid product in a form capable of being handled based on hydrophobic mineral powder such as talcum or mica powder, in particular for cosmetic or hygienic use. This process is characterized in that a hydrophobic mineral powder, particularly based on talcum or mica, is impregnated using a volatile liquid binder in proportions by weight such that the proportion of volatile liquid binder is at least equal to 5% and the proportion of mineral powder at least equal to 80%, and in that the resulting impregnated powder is pressed so as to shape it and to provide it with cohesion ensuring the rigidity of the product. The solid product obtained can take the form of a stick ( ) that can be used to ensure a deposit of talcum or mica by contact.
