making method of Bulk L-Cysteine hydrochloride anhydrous powder.

Hydrolysis of hair with hydrochloric acid, distillation under reduced pressure, distillation of hydrochloric acid after decolourisation, filtration, take the filtrate with ammonia and neutralisation to get the crude crystals of L-cystine, and then dissolved in ammonia and neutralisation, recrystallisation, hydrochloric acid and electrolytic reductions, concentration, cooling, crystallisation, drying system.

Frequently Asked Questions.

Q: Is this the same as NAC?

A: No-NAC is a modified form that is more bioavailable but more costly.

Q: Is it vegan friendly?

A: Most synthetic L-cysteine is vegan, but some food-grade L-cysteine is derived from duck feathers/human hair (check sources).

Q: Does it help with hangovers?

A: Indirectly helps with alcohol metabolism and glutathione recirculation.

Q: Best time to take it?

Product Methods of L-Cysteine hydrochloride anhydrous.

Hydrolysis-Electrolysis Method

Take pig hair, hair as raw material by hydrolysis, adjust the isoelectric point of cystine separation of cystine, and then electrolysis reduction of cystine, the production of cysteine. Hydrolysis to separate out cystine pig hair, hair [HCl, 117 ℃, 7h] → [acid hydrolysis] hydrolysate [NaOH, pH 4.8] → [neutralisation] L-cystine (crude) electrolytic reduction in two separate pools, a pool filled with 1 mol / L HCl inserted into the ink stick, connected to the power source of the positive electrode, this pool for the anode, the other pool is filled with hydrochloric acid solution of cystine (cystine: concentration) HCl:water=1:1:4), inserted into the lead plate, connected to the negative pole of the power supply, this pool is the cathode. Add a salt bridge between the two pools to connect.

Turn on the power to adjust the current 5A, electrolysis, about 6-7h electrolysis is completed. Take the electrolyte a little drop of pyridine, no turbidity indicates that the electrolysis is complete.L-cysteine [HCl] → [electrolysis reduction] L-cysteine hydrochloride [decolourisation, concentration, crystallisation] → L-cysteine hydrochloride crystallisation decolourisation, concentration, crystallisation after the completion of electrolysis, cut off the power supply, according to the amount of feed to add 10g / L (1%) of activated carbon, heated to 70 ° C, keep warm for half an hour. Filter the filtrate.

And will be concentrated under reduced pressure until there are crystals, stirring to make the crystals completely precipitated, filtered to take the crystals, washed with 95% ethanol, at 60 ℃ below the vacuum drying, that is, to obtain the L-cysteine hydrochloride without water of crystallisation.
