Problems solved by technology

[0009] With the advancement of technology, new alternative preservative products will be loved by more consumers. At present, domestic cosmetics use more polyols, medium-carbon chain esters, p-hydroxyacetophenone, and caprylyl hydroxamic acid. Now more and more are used in baby products, among which polyol complex p-hydroxyacetophenone and caprylyl hydroxamic acid are the choice of most children's product preservatives, but because the formula contains a lot of fresh milk, 4-Hydroxyacetophenone has potential incompatibility with certain proteins, and the formulation is prone to discoloration and instability

[0034] 2) Mix water (to make up the balance of 100 g, the same below) and glycerin and heat to 80-85° C. to obtain water phase B.

[0035] 3) After mixing phase A and phase B, homogenize for 10 minutes, start stirring at the same time, turn off homogenization after 10 minute...

Embodiment 2

[0036] Embodiment 2: The difference between embodiment 2 and embodiment 1 is only in the way of adding fresh milk.

[0037] It specifically includes the following steps: 1) first filter the fresh milk through gauze to remove the cell tissue contained in it and the impurities mixed in the collection process, and then carry out centrifugal degreasing through a large-capacity centrifuge (centrifuge speed 3000r, time 30min, temperature 25°C), filtered through gauze to obtain skimmed fresh milk, removed the fat layer separated from the upper layer, and kept the fat layer for later use; adjusted the pH of the skimmed milk to 4.6 with hydrochloric acid for acid coagulation, left it for a period of time, and centrifuged to skim it. Take the supernatant (whey) by gauze filtration; then keep the obtained casein precipitate for later use; remove most of the water and inorganic salts from the obtained whey through a hollow fiber ultrafiltration membrane, and then remove the inorganic The ...

Embodiment 3

[0041] Embodiment 3: The difference between embodiment 3 and embodiment 2 is only that the preservative components are different, and the preservatives include: propylene glycol 0.1g, o-cymene-5-alcohol 0.02g, 1,2-hexanediol 0.03g , 0.05 g of ethylhexylglycerin, 0.03 g of methylparaben, and 0.15 g of phenoxyethanol.
