04Formulation & handling notes

Formulation & handling notes

The practical points our technical team raises with buyers of this material — the things that decide whether a batch behaves in your process.

Taurine is a sulphonic acid, not a carboxylic amino acid, and that single structural fact drives most of its formulation behaviour: the sulphonate group is a far stronger acid than a carboxyl (a dissociation constant of about 1.5 is reported), which is why a 5% solution sits at pH 4.1-5.6 and why taurine is stable in the low-pH carbonated systems where energy drinks live.

This lot is supplied without anti-caking agent, which is a genuine differentiator. Most bulk taurine is sold with silicon dioxide added for flow. If you are formulating for a clean-label market, a 'no additives' declaration, or an application where silica would be an unwanted excipient, an anti-caking-free grade is the one to specify — and it will need to be handled in a controlled-humidity room to compensate.

It is effectively insoluble in alcohol: 100 parts of 95% ethanol dissolve 0.004 parts of taurine at 17 °C. Alcohol-based liquid formats are off the table entirely, and hydro-alcoholic systems need bench testing.

Aqueous solubility of 94.9 g/L at 25 °C is high enough that the 1000-2000 mg/can typical of an energy drink is trivially achievable — taurine is essentially never the limiting solubility in a beverage.

Documented shelf life is unusually well-characterised for a bulk amino acid: three batches stored in sealed polyethylene bags showed a 36-month shelf life at 25 °C, with no loss over six months under accelerated conditions at 40 °C. That is a defensible answer when a customer asks for stability data.

Bulk density is 0.65-0.75 g/cm3 against a true density of about 1.7, so the powder is roughly 60% void. For scoop-filled and can-dosed products, use the bulk figure, and re-measure it on the anti-caking-free grade because removing the silica changes flow and packing.

It decomposes rather than melting (about 325 °C per the Merck Index) and evolves both SOx and NOx on thermal decomposition — relevant to your own dust-explosion and thermal-hazard assessment, not just to cooking steps.

06Regulatory status by market

Regulatory status by market

Status of the raw material, stated as conservatively as our sources allow. This is supply-chain information, not regulatory advice — confirm the position for your finished product and destination market with your own regulatory counsel.

Market	Status	Basis
United States	GRAS Notice GRN 586 (notifier Intertek Scientific & Regulatory Consultancy) for taurine closed with an 'FDA has no questions' letter on 9 December 2015. The notified use was narrow: 'for use as an ingredient in enhanced water beverages at a concentration of 45 parts per million (0.0045%)'. Taurine is not one of the amino acids listed in 21 CFR 172.320. GRN 586 is not a general food clearance and does not cover the far higher taurine levels used in energy drinks or supplements, which rest on other bases.	FDA GRAS Notice Inventory GRN 586; 21 CFR 172.320
European Union	EFSA has published a scientific opinion covering taurine, and PubChem's taurine record cites EFSA Journal 10(6):2736 (2012) as the source of its physical, pH, density and shelf-life data. The precise regulatory consequence of that opinion for food and supplement use must be read from the opinion and the relevant authorisation.	EFSA Journal 10(6):2736 (2012); EU food and feed additive law
China	Taurine is widely used in Chinese beverages and infant formula; its status as a nutrient fortification substance under GB 14880-2012 needs confirming for the specific application.	GB 14880-2012 and NHC announcements
Japan	No JP XVIII Official Monograph for this substance was located.	JP XVIII

A meta-analysis of ten peer-reviewed studies with taurine doses from 1 to 6 g/day reported an improvement in overall endurance performance, and used meta-regression to assess the contribution of dose and of acute versus chronic supplementation periods. Waldron M, Patterson SD, Tallent J, Jeffries O. Sports Med. 2018;48(5):1247-1253. PMID 29546641 DOI 10.1007/s40279-018-0896-2 Source
A three-level meta-analysis of 23 randomised trials (69 effects, N = 308) reported small-to-moderate improvements in overall performance after a single acute taurine dose (g = 0.25, 95% CI 0.10-0.39), with no significant dose-response detected across the commonly used 1-6 g range and both capsule and beverage formats appearing effective. Deng H, Song T, Yin M, et al. Scand J Med Sci Sports. 2025;35(9):e70123. PMID 40852891 DOI 10.1111/sms.70123 Source
A meta-analysis of seven randomised controlled trials (402 individuals) reported that taurine, alone or combined with exercise training, did not show significant effects on cognitive scores, and concluded the evidence was insufficient to support an effect on cognitive function. Cao Q, Nie Z, Liu Y, Xu J, Chen L, Han S. Int J Food Sci Nutr. 2025;76(4):370-380. PMID 40320621 DOI 10.1080/09637486.2025.2499044 Source

09Procurement FAQ

Procurement FAQ

01What exactly does 'JP' mean on this taurine?

We are checking it rather than assuming, because it matters to your QA. Our offer sheet says JP grade; we could not confirm a Japanese Pharmacopoeia Official Monograph for taurine in the JP XVIII English text, so 'JP' here may refer to the Japanese Standards of Food Additives or to a manufacturer's grade designation. Ask us for the specification document the grade actually refers to and we will send it before you order.

02Why does anti-caking-free matter?

Most bulk taurine ships with silicon dioxide added for flow. This lot has none, which is what you want for clean-label declarations, for applications where silica is an unwanted excipient, or where you do your own granulation. The trade-off is handling: without the flow aid you need a drier room and tighter first-in-first-out.

03Do you have stability data for taurine?

Yes, and it is unusually solid for a bulk amino acid. Published data on three batches stored in sealed polyethylene bags show a 36-month shelf life at 25 °C, with no loss after six months of accelerated storage at 40 °C. We will send the batch COA and the manufacturer's own retest date with your quote.

04Can I use it in an alcohol-based shot?

No. Taurine is effectively insoluble in ethanol — 100 parts of 95% alcohol dissolve 0.004 parts. It is an aqueous and dry-blend ingredient.

05How much bulk taurine can you hold for a beverage programme?

Around 7.8 tonnes in ready stock, cartoned, out of Shanghai. For a canning programme tell us your monthly draw and we will discuss holding stock against a schedule.

06What is the MOQ for L-Taurine?

MOQ is quote-based and flexible. Tell us your target quantity in the RFQ — for core in-stock SKUs we can usually accommodate both trial orders and multi-tonne volumes.

07Can I get a sample of L-Taurine before ordering?

Yes — samples are available on request for evaluation and lab verification. Mention it in your RFQ and we will confirm the arrangement.
