preparation Embodiment 1-5

[0021] The oil-in-water cream provided by the invention is prepared through the following steps:

[0022] A. Add quantitative deionized water, disodium EDTA, acrylates / C10-30 alkanol acrylate crosslinked polymer and xanthan gum dispersed with glycerin into the water pot, and heat to 70-75°C, Add allantoin and methylparaben afterwards, after dissolving completely, the aqueous phase material is prepared for use;

[0023] B. Add quantitative petrolatum, polydimethylsiloxane, mineral oil, cetearyl alcohol, ethylhexyl palmitate, cetearyl glucoside and stearyl ether-21 to the oil In the pot, heat to 70-75°C and melt completely to obtain the oil phase material for use;

[0024] C. Vacuumize the emulsification pot after preheating, use negative pressure to pump 2 / 3 of the water phase material into the emulsification pot, stir and homogenize, and then use negative pressure to pump the oil phase material into the emulsification pot, and finally pump Add the remaining water phase mater...

Abstract

The invention relates to an oil-in-water emulsifiable paste, and particularly relates to an oil-in-water emulsifiable paste with high stable performance. The oil-in-water emulsifiable paste comprises the following components: deionized water, ethylhexyl palmitate, aloe extract, petrolatum, glycerol, polydimethylsiloxane, mineral oil, cetostearyl alcohol, cetearyl glucoside, steareth-21, phenoxyethanol, acrylamide/acrylic acid copolymer, allantoin, xanthan gum, methyl hydroxybenzoate, acrylics/C10-30 alkyl alcohol acrylate cross-linked polymer, EDTA (ethylenediaminetetraacetic acid) disodium salt, ethylhexylglycerin, polyisobutene and polysorbate-20. The invention further provides a preparation method for the oil-in-water emulsifiable paste. According to the oil-in-water emulsifiable paste and the preparation method for the same disclosed by the invention, oil and active matters are re-emulsified, thus reducing the influence of the oil and the active matters which are not included by water on stability, and improving the stable performance of the oil-in-water emulsifiable paste; simultaneously, more oil can be added, and lots of active substances can be added at a low temperature.

Description

technical field [0001] The invention relates to a cream, in particular to an oil-in-water cream with high stability and a preparation method thereof. Background technique [0002] Cream refers to a uniform semi-solid external preparation formed by dissolving or dispersing drugs in an emulsion-type base. It is widely used in medicines and cosmetics, and as an essential product for human life, it has always attracted the attention of consumers. [0003] Creams can be divided into oil-in-water formulations and water-in-oil formulations. Creams are used in the cosmetics industry. The main appeal is to use creams to moisturize, relieve allergies, anti-wrinkle, and whiten after cleaning the skin of the face or body; stage, the demand for functional skin care products in cosmetics is increasing day by day, and consumers need products that can bring clear use effects, so it is necessary to add a large amount of oil to play the role of moisturizing and sealing, and also need to add ...
