[0003] Although silicone oil is used in cosmetics to give the product an excellent sense of use, since silicone oil may contain D4 (octamethylcyclotetrasiloxane) and D5 (decamethylcyclopentasiloxane), and D4 and D5 have nothing to do with persistence Similar to organic pollutants, it is difficult to degrade in the human body and has accumulation characteristics
And these two chemicals may cause damage to the reproductive ability of the human body, such as uterine tumors

Abstract
The invention provides emulsion cream and a preparing method thereof. The emulsion cream is prepared from, in units of the total weight of emulsion cream, 0.1-10% of an emulsifying agent, 0.5-25% of a humectant, 0.01-1% of an aqueous-phase thickening agent, 0.1-10% of an oil-phase thickening agent, 1-30% of fluid oil, 0.01-5% of a skin conditioner and 20-85% of water, and preferably, the emulsion cream is prepared from 3-6% of the emulsifying agent, 5-15% of the humectant, 0. 1-0.5% of the aqueous-phase thickening agent, 1-6% of the oil-phase thickening agent, 10-15% of the fluid oil, 0.5-2% of the skin conditioner and 55.5-80% of the water. The emulsion cream is free of silicone oil, mild, easy to degrade in the human body, free of accumulation, environmentally friendly, nontoxic and harmless and has good emulsifying capacity and does not stimulate the skin.
Description
technical field [0001] The invention includes an emulsion cream and a preparation method thereof, belonging to the field of daily chemicals. Background technique [0002] At present, most cosmetics contain silicone oil, because silicone oil has excellent properties such as heat resistance, hydrophobicity, physiological inertia and low surface tension. The application of silicone oil in the production of cosmetics can improve the performance of cosmetics. For example: the low surface tension and viscosity of silicone oil make it easy for other components of cosmetics to spread into a thin film on the skin surface without stickiness; the detackifying performance of silicone oil makes it compatible with vaseline, paraffin, beeswax, lanolin, etc. Non-sticky products can be obtained; and volatile silicone oil can also endow cosmetics with properties such as quick drying, smoothness, antifouling, and good gloss. [0003] Although silicone oil is used in cosmetics to give the pro...
