Problems solved by technology

The dispersion and stability of the emulsion are poor, and the uniformity of the product needs to be strengthened
[0004] For example, CN111643394A discloses a cosmetic emulsion containing β-nicotinamide mononucleotide and its preparation method, including the following components in parts by weight: β-nicotinamide mononucleotide: 10-60 parts; Sugar: 20-40 parts; Water: 5-10 parts; Glycerin: 40-50 parts; Mineral oil: 35-45 parts; Ethylhexyl palmitate: 30-40 parts; 6-aminonicotinamide: 25-30 parts parts; polydimethylsiloxane: 20-30 parts; polyglycerin: 20-30 parts; distearate: 15-20 parts; squalane: 5-10 parts; sodium hyaluronate: 1- 6 parts; methyl paraben: 1-2 parts, the cosmetic emulsion prepared by the above formula has excellent moisturizing, anti-oxidation and anti-aging effects, but the amount of emulsifier used in this product is relatively high, which brings more or less damage to the skin. A little astringent and heavy feeling, and some irritation to the skin

Embodiment 1

[0048] This embodiment provides an oil-in-oil emulsion, which prepares a material having a D-phase (4% butanediol, 3%, PEG40 hydrogenated castor oil 1%, pure water 2%), II phase (Hobham seed oil 16) %), Phase III (pure water 2%) and IV phase (pure water). The preparation method is as follows:

[0049] (1) Heat the D phase, II phase from 80 ° C to dissolve;

[0050] (2) Emulsified 8 min after the dissolved D phase, II phase mixed homogenization was carried out at 8000 rpm velocity and 70 ° C;

[0051] (3) The product of the step (2) is mixed with III at 5000 rpm velocity, stirred at 70 ° C for 15 min;

[0052] (4) The product was mixed with the IV phase at 5000 rpm velocity, stirred at 70 ° C for 15 min to give the water-filled emulsion.

[0053] The obtained water-in-oil emulsion was observed with TEM, such as figure 1 As shown: Emulsified particles are uniform and the particle size is small.

Embodiment 2

[0055] This embodiment provides an oil-in-water type emulsion, and the difference between the preparation of the raw material and the first embodiment is only to replace the PEG40 hydrogenated castor oil to replace the IV phase (pure water) to IV phase (essence) The amount of liquid remaining), the other components and the content remain unchanged. The preparation method is the same as in Example 1.

[0056] The obtained water-in-oil emulsion was observed with TEM, such as figure 2 As shown: Emulsified particles are uniform and the particle size is small.

Embodiment 3

[0058] This embodiment provides an oil-in-oil emulsion, and the difference in the preparation of the raw material and the first embodiment is only to replace the PEG40 hydrogenated castor oil to PEG80 hydrogenated castor oil, other components and content remain unchanged. The preparation method is the same as in Example 1.

Abstract

The invention relates to a method for preparing an oil-in-water emulsion by using a D-phase emulsification method and an application of the method. Preparation raw materials for the method comprise aD phase, a II phase, a III phase and a IV phase, wherein the D phase comprises butanediol, glycerol, PEG hydrogenated castor oil and pure water; the II phase comprises an oil-soluble component; the III phase comprises pure water; the IV phase comprises pure water or a water-soluble component. According to the method for preparing the oil-in-water emulsion, the D-phase emulsification method is adopted for preparation, under a specific component formula, the prepared oil-in-water emulsion can emulsify massive grease components with an extremely small amount of emulsifier, the astringent feelingand the heavy feeling brought by the emulsifier to the skin are reduced, besides, the greasy feeling brought by grease can be reduced, and the oil-in-water emulsion is light and easy to absorb. More importantly, the prepared oil-in-water emulsion is good in stability at normal temperature, high temperature or low temperature, the particle size of emulsified particles is smaller than 2 [mu]m, and the emulsified particles are uniform in size. The preparation method is simple in process, time-saving and energy-saving.

Description

Technical field [0001] The present invention belongs to the field of cosmetic technology, and more particularly to the preparation method of oil-in-oil emulsion and its applications, and more particularly to a method of preparing water-filled oil-type emulsion using D-phase emulsion. Background technique [0002] Most of the skin care cosmetics products are the emulsion system, while the general emulsion system is large due to the proportion of formulation components and the different processes used for different processes, and therefore, the product is dispersible, and the stability is poor. The product is uneven, the active ingredient dispersed in the ordinary emulsion system, due to the above reasons, it is difficult to play the function of functionality. At the same time, the emulsifier dosage in the ordinary emulsion system is often higher, bringing more or less astringent and thickness to the skin, and has certain irritation to the skin. [0003] For example, CN102772337A d...
