摘要：
The solution according to the invention consists in the first place, in order to obtain a pre-emulsion, a certain amount of oil phase consisting of a fragrance composition and emulsifier and an aqueous phase, being a mixture of water and preservative, is dispersed using a mechanical stirrer with a rotational speed of agitators from 450 to 550 rpm for 10 to 15 minutes. The process is carried out at a temperature of 20°C to 30°C, and the obtained pre-emulsion is then subjected to a homogenization process using an ultrasonic probe with a sonication power of 10 to 30 W. The time for the homogenization process is determined by obtaining a transparent system. The oil phase is obtained by combining from 5 to 10% by weight of an emulsifier and 5 to 15% by weight of a fragrance composition, the weight ratio S: O of the emulsifier (S) to the fragrance composition (O) ranging from 1: 1 to 1 : 3. On the other hand, the aqueous phase is obtained by combining the preservative in an amount of 0.00025 to 1% by weight with water in an amount to make up to 100% by weight of the ingredients.
