Pharmaceutical grade talc is produced in Guangxi without sand.
It can be used in tablets.
Talc talc is made by purifying, crushing and drying
.
Talc is a white or off-white, fine, non-sand-like powder with a greasy feel to the touch
.
Gas micro, tasteless
.
Talc is insoluble in water, dilute hydrochloric acid or dilute sodium hydroxide solution
.
[Identification] Take talc powder and perform the tests in [Identification] (1) and (2) under the item of talc, and it shows the same reaction
.
[Check] pH Take 10g of this product, add 50ml of water, boil for 30 minutes, replenish the evaporated water from time to time, and filter
.
The filtrate should show a neutral reaction when it encounters neutral litmus paper
.
Take 5g of the product soluble in water, accurately weigh it, put it in a 100ml beaker, add 30ml of water, boil for 30 minutes, replenish the evaporated water from time to time, let it cool, filter it through a slow-speed filter paper, add 5ml of water to the filter residue to wash, and the washing solution is mixed with The filtrates were combined, evaporated to dryness, and dried at 105°C for 1 hour.
The remaining residue should not exceed 5 mg (0.
1%)
.
Take about 1g of the product soluble in acid, accurately weigh it, put it in a 100ml conical flask with stopper, add 20ml of dilute hydrochloric acid precisely, weigh it, soak it at 50°C for 15 minutes, let it cool, and weigh it again.
Make up the lost weight with dilute hydrochloric acid, shake well, filter through medium-speed filter paper, accurately measure 10ml of the subsequent filtrate, add 1ml of dilute sulfuric acid, evaporate to dryness, ignite to constant weight, and the remaining residue should not exceed 10.

.
The talc in the tablet is a purified hydrous magnesium silicate that acts primarily as a flow aid
.
There is also a lubricating white subdivision containing magnesium stearate
.

.
Features: Contains a large amount of silicon
.
It has the effect of blocking infrared rays, thus enhancing the sunscreen and anti-infrared properties of cosmetics
.
Talc is used as an additive in the pharmaceutical and food industries
.
Features: It has the characteristics of non-toxic, tasteless, high whiteness, good compatibility, strong gloss, soft taste and strong smoothness
.
