Problems solved by technology

If this kind of powder is made into oil dispersion slurry, it is difficult to disperse evenly, and the loss of equipment is also great, and the dispersion slurry is unstable and very easy to separate
Therefore it is difficult to make hydrophobic and oleophobic powder into simple oil dispersion slurry or water dispersion slurry like traditional hydrophobic and oleophilic or hydrophilic and oleophobic powder, and it has not been reported that hydrophobic and oleophobic powder is prepared into simple oil dispersion slurry or water dispersion slurry.

[0089]

[0090]

[0091] Preparation Process:

[0092] 1. Weigh the raw materials of phase A in a beaker in turn, heat at 80°C until the raw materials are completely melted, then stop heating and stir evenly;

[0093] 2. Add the raw materials of phase B to phase A in turn, stir (380-400 rpm) for 8-10 minutes, and then homogenize (10000-20000 rpm) for 5 minutes to disperse the powder evenly;

[0094] 3. Under rapid stirring (400-500 rpm), slowly add phase C to phase AB to make the emulsification complete. High-speed homogenization (10000 rpm) until the material body is uniform and fine;

[0095] 4. Use a three-roll machine to grind 3 to 4 times to get "1# pre-emulsified slurry of hydrophobic and oleophobic powder".

Abstract

The invention discloses a pre-emulsified powder syrup of hydrophobic and oleophobic powder, and a preparation method and application thereof. The pre-emulsified powder syrup of the hydrophobic and oleophobic powder is prepared from the following components in parts by weight: 10 to 70 parts of hydrophobic and oleophobic powder, 10 to 40 parts of grease, 0.5 to 8 parts of dispersing agent, 0.1 to 5 parts of thickening stabilizer, and 8 to 50 parts of moisturizing agent, the defects of the application limit of the hydrophobic and oleophobic powder can be overcome, the pre-emulsified powder syrup has the advantages of easiness in dispersion, uneasiness in powder leakage and color drifting, good compatibility, good stability, good makeup maintaining performance and the like in a cosmetics formula, and does not produce dust pollution in the application process.

Description

technical field [0001] The invention relates to the field of cosmetic raw materials, in particular to a cosmetic pre-emulsified slurry and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's demand for cosmetics is also increasing rapidly. In the past, most of the makeup such as liquid foundation, foundation cream or whitening cream had waterproof function, and few had oil-proof function. During use, the oil and sweat secreted by the skin can easily damage the makeup. [0003] In recent years, fluorine-containing treatment agents have been used for surface treatment of cosmetic powders, making the powders hydrophobic and oleophobic, thereby enhancing the durability of makeup products, which perfectly caters to the needs of the current cosmetics market. For example, JP2005053807 and JP2008037813 disclose the treatment of powder with fluorine-containing reagents to impart hydrophobic and oleophobic properties to the ...
