Step 3: open vacuum pump, material in water phase tank is transferred in emulsion tank, control vacuum degree for -0.06MPa~-
0.08MPa opens stirring (scraper plate speed of agitator is 40 turns/min), while opening cooling makes material be cooled to 30 DEG C or less.
4. a kind of preparation method of Benzagel according to claim 2, it is characterised in that: the S30 gel
The step of mutually preparing are as follows:
Step 1: the glycerol of partial purification water and recipe quantity is added into water phase tank, stirring (revolving speed is 300 turns/min) is opened,
It opens steam and is heated to 50 DEG C~60 DEG C, improve speed of agitator to 800 turns/min, be slowly added to the carbomer of recipe quantity
980, make the fully dispersed swelling of carbomer (swelling time is about 30min~60min)；
Step 2: open vacuum pump, gel is mutually filtered into emulsion tank (40 mesh of sieve mesh number), control vacuum degree be-
0.06MPa~-0.08MPa opens stirring (scraper plate speed of agitator is 40 turns/min), while opening cooling makes material be cooled to 30
DEG C or less.
5. a kind of preparation method of Benzagel according to claim 2, it is characterised in that: the S40 activity
The step of mutually preparing are as follows:
Step 1: the natrium adetate of suitable purified water, recipe quantity is added into stainless steel barrel, it is stirred to dissolve；It adds
The propylene glycol of recipe quantity, stirring make to mix；
Step 2: the benzoyl peroxide of recipe quantity is added, stirring makes wetting, and uniformly sample detection raw material granularity is examined according to granularity
The following granularities of the fruit that comes to an end progress comply with standard or the non-compliant step operation of granularity.
6. a kind of preparation method of Benzagel according to claim 5, it is characterised in that: the raw material granularity
Inspection method are as follows: it takes sample appropriate, is placed on glass slide and applies straticulation, thin layer area is equivalent to coverslip area, 3 are applied altogether,
It is measured according to granularity and determination of particle size distribution (Chinese Pharmacopoeia 0,982 first method of version general rule in 2015), granularity control standard: 25 μm
Particle below must not be less than 95%, and 100 μm or more of particle is not greater than 1%, must not detect 180 μm or more of particle；
It when the bulk pharmaceutical chemicals granularity meets granularity control standard, transfers the material into emulsion tank, weighs surplus purified water profit
It washes container and is transferred in emulsion tank；
When the bulk pharmaceutical chemicals granularity does not meet granularity control standard, transfers the material into colloid mill and ground, open freezing
(2 DEG C~10 DEG C) control temperature of charge of water are met the requirements of the standard at 60 DEG C hereinafter, being ground to granularity, transfer the material into emulsion tank
In, it weighs surplus purified water rinse colloid mill and container and is transferred in emulsion tank.
