preparation example Construction
[0038] The present invention also provides a preparation method of the above shea butter composition, comprising the steps of:
[0039] (1) Mix emulsifier, co-emulsifier, liquid oil and stabilizer to obtain a uniform and transparent mixture;
[0040] (2) The mixture is mixed with shea butter to obtain a shea butter composition.
[0041] The invention mixes the emulsifier, co-emulsifier, liquid oil and stabilizer to obtain a uniform and transparent mixture. In the present invention, the mixing temperature of the emulsifier, co-emulsifier, liquid oil and stabilizer is preferably 35-80°C, more preferably 40-70°C, most preferably 45-65°C; the mixing time Preferably it is 10-30min, more preferably 12-25min, most preferably 15-20min; the mixing is preferably stirring and mixing, and the rotating speed of the stirring and mixing is preferably 100-600rpm, more preferably 150-550rpm, most preferably 200~500rpm. In the present invention, the mixing time is preferably from the time wh...

[0052] Will account for the mass percentage content of final product be 16% polysorbate 80, 15% polyoxyethylene castor oil-40, 12% isopropyl myristate, 16% ethyl oleate, 13% Octyldodecanol, 3% pentaerythritol, 5% 1,2-hexanediol, 0.5% gum arabic, and 1.5% butylated hydroxytoluene are mixed to obtain a uniform and transparent mixture. Stir and mix at a stirring speed of 300rpm for 25min in a water bath at 35°C;
[0053] Add shea butter that accounts for 18% of the mass percentage of the final product to the mixture, stir at a stirring speed of 300 rpm for 25 min in a water bath at 35°C until a uniform transparent solution is formed, and cool to room temperature , to obtain the shea butter composition.
[0054] Take the shea butter composition obtained in this example, and use ultrapure water to dilute to 100 times according to the volume multiple to obtain an O / W emulsion. At 25°C, measure the average particle size of the shea butter composition by a laser particle size analyze...
