Embodiment 1
[0065] The composition proportioning and preparation process of the present embodiment are as follows:
[0066]
[0067]
[0068] Preparation Process:
[0069] ① Add the weighed sodium pyruvate, polysorbate 80, pyrrolidone carboxylic acid, propylene glycol, simethicone, methyl p-hydroxybenzoate, propyl p-hydroxybenzoate, disodium EDTA, and orange essence into the purified water, Stir well with a glass rod.
[0070] ② Slowly add cationic guar gum to the above mixed solution, and stir while adding.
[0071] ③ Use citric acid and sodium citrate to adjust the pH to 5-8;
[0072] ④Add water to 100g, stir well, and let stand to swell.
Embodiment 2
[0074] The composition proportioning and preparation process of the present embodiment are as follows:
[0075]
[0076]
[0077] Preparation Process:
[0078] ①Put half of the total amount of purified water required into a clean beaker, then add cationic guar gum, stir to disperse, let it stand for swelling, and then heat it in a water bath at 70°C for 30 minutes, stir fully while swelling, and then naturally cool down.
[0079] ②Add sodium pyruvate, polysorbate 20, polyethylene glycol stearate, glycerin, propylene glycol, simethicone, sodium benzoate, edetate disodium, and lemon essence to the other half of the total purified water required for purification water, stir thoroughly;
[0080] ③Mix the above ① and ② materials, then fully stir and disperse, and swell overnight.
[0081] ④ Use succinic acid and disodium succinate to adjust the pH to 5-8;
Embodiment 3
[0083] The composition proportioning and preparation process of the present embodiment are as follows:
[0084]
[0085] Preparation Process:
[0086] ①Mix sodium pyruvate, polyethylene glycol stearate, glycerin, propylene glycol, simethicone, methyl paraben, propyl paraben, polysorbate 80, and lemon essence, and heat to 50~70℃ to make the system uniform.
[0087] ② Add edetate disodium into purified water, stir evenly to dissolve it completely.
[0088] ③ Add cationic guar gum to ①, stir to disperse.
[0089] ④Use the homogenizer to homogenize the solution of ②, then add ③ into ②, and homogenize while adding. Use a pH regulator to adjust the pH to 5-8, add purified water to 100 g, and continue stirring until uniform.
