Abstract

The invention belongs to the filed of daily-use chemical industry, in particular to transparent nano oil-in-water emulsion and application. The oil drops of the nano emulsion have diameter less than 100 nanometers and are spread in water phase; the oil content accounts for 15-25% of the total weight; the nano emulsion contains an amphiphilic surfactant which accounts for 1-10% of the weight of the nano emulsion, is absorbed on the oil/water interface and comprises ionic and nonionic amphiphilic surfactants; wherein, the ionic amphiphilic surfactant is liquid below 45 DEG C. The nano oil-in-water emulsion has oil drops with small grain sizes and stable storage and can be applied in cosmetics or cosmeceutical and to care of skin, hair, skin around eyes and on the face, etc.

Description

technical field [0001] The invention belongs to the field of daily chemical industry, and particularly relates to a transparent oil-in-water nanoemulsion, and also relates to the application of the emulsion in cosmetics. Background of the invention [0002] As we all know, oil-in-water emulsion is an emulsification technology used in the cosmetic industry to prepare products such as emulsion, nourishing water, essence and toilet water. In addition, there are transparent microemulsions. Strictly speaking, microemulsions are not an emulsion; they are transparent solutions composed of micelles, which means that the oil in them contains a high proportion of surfactants and additives and in They dissolve under the joint action, and the particle size becomes extremely small after the oil is dissolved, making the system transparent. However, the shortcoming of microemulsion is precisely because its high proportion of surfactant content causes skin allergies or causes skin stickine...
