CBDa Isolate Powder, 5 g

Description

Five grams of CBDa isolate powder, the raw acid form of cannabidiol that has never been heated. That is the whole specification and it is a chemistry statement rather than a marketing one: cannabidiolic acid is what the living plant makes, and it converts to cannabidiol when heat is applied, which is why almost everything else in this catalogue contains the second rather than the first.

What is in a jar of cbda isolate powder

One compound, an assay percentage and a weight, with the certificate converting the percentage into milligrams.

• CBDa isolate powder: 5 g of cannabidiolic acid
• Form: crystalline powder, with the assay percentage on the certificate
• State: the raw acid form, never heated
• Storage: cool and dry, because heat converts it
• Sold as: bulk material by weight, not portioned
• Price: $79 a jar, with the price per milligram printed under it

Why cbda isolate powder has to stay cool

Because decarboxylation is a temperature and time reaction. Cannabidiolic acid loses a carbon dioxide molecule and becomes cannabidiol when it is heated, which happens slowly at room temperature and quickly in an oven. A jar left somewhere warm for long enough is gradually converting itself into a different compound, and the assay would show it. That is not a shelf life claim about spoilage, it is a statement about what the material is, and it is why the storage instruction on CBDa isolate powder is more than boilerplate.

What the acid form rules out

Baking, cooking and anything involving heat, which removes a great many of the uses the other isolates are bought for. It also means this cannot be smoked or dabbed and remain what it is: the nail converts it on contact. CBDa isolate powder is bought for cold preparations, tinctures made without heat, and for formulation work where the acid form is the point. The bulk and isolate range states the form on every listing because the difference is not visible in a jar.

Weighing and dissolving it

Use a scale that reads to a hundredth of a gram. Volume measures are unreliable with a powder this fine, and the difference between a level and a heaped spoon is larger than most of the amounts anyone is working to. The acid form has somewhat different solubility behaviour from cannabidiol, being more polar, which affects how readily it goes into a given carrier. Nothing on this page suggests a quantity to take, because material sold by weight is not a serving.

Testing

Every lot of CBDa isolate powder is assayed by an independent laboratory: the cannabinoid profile with the assay percentage stated and the acid and neutral forms reported separately, residual solvents in parts per million, heavy metals, pesticides and microbials. Separating the two forms on the sheet is the part that matters here, because a lot that has partially converted would still look like a high purity cannabinoid on a sloppier panel. Lots under their stated purity are withdrawn and the failing certificate stays published, as this note explains.

What is published on cannabidiolic acid

Much less than on cannabidiol, and mostly preclinical. Cannabidiolic acid has been studied in cell culture and animal models, with very little human work, and there is no established human dose range and no approved medicine containing it. Some published work has looked at how its absorption compares with cannabidiol, with results that do not settle anything. Cannabidiol itself has the proper record, anchored by a prescription oral solution at 10 to 20 mg per kilogram per day. Those are descriptions of published research and its doses rather than claims about this powder, and the indexed papers are at PubMed.

Keep it sealed, cool, dry and out of the light. The certificate for the current lot is linked here.
