Abstract
Method for synthesizing greases by adding at least one co-surfactant to the mixture of the thickener in the oil. The addition is made at the initial stage of the formation of a three-dimensional filamentary network of the grease at a temperature between the waxy transition temperature and the melting point of the thickener. The process permits good control of the mechanical behaviour of the greases.
