Alginic Acid
Alginic acid is the free acid form of the alginate family — the polysaccharide extracted from brown seaweed before it is neutralised to a soluble salt — and is identified in food additive systems as E400. Unlike the sodium and potassium salts it is only slightly soluble in cold water; it swells and hydrates, and it dissolves once neutralised in situ. That behaviour is exactly why it is used where the alginate has to be delivered in acid form or activated within the formulation. Allzone quotes this material per enquiry: grade, packing, origin, documentation and Incoterm are decided in your quotation, not fixed by this page.

Technical & procurement detail
Functions in formulation+
Alginic acid is used as a thickener, stabiliser, emulsifying aid and general formulation aid, and as a swelling and disintegration component in solid formulations. In food it contributes texture and structure; in pharmaceutical, nutraceutical and personal care formulation it is used for its swelling and structuring behaviour. Allzone makes no therapeutic, medical or disease-treatment claim for this material; regulatory suitability is confirmed for the specific grade and intended use.
What decides the alginic acid you actually need+
Whether your process can neutralise the acid in situ or genuinely needs a pre-formed soluble salt is the first question, and it often redirects an enquiry to sodium or potassium alginate instead. Beyond that, particle size, swelling and hydration behaviour, the process step where the material is added, and the documentation your sector requires decide the grade quoted.
Alginic acid is the precursor, not a soluble alginate salt+
Sodium alginate and potassium alginate are the neutralised, water-soluble salts and each has its own canonical page. Alginic acid is the free acid and behaves differently in water, so the three are not interchangeable. Propylene glycol alginate is the esterified derivative and is a separate record again. Carrageenan and agar are unrelated seaweed hydrocolloids with their own pages on this catalogue.
What this page does not state+
This page asserts no viscosity, assay, purity, particle size, moisture, ash, degree of esterification, origin, packing, minimum quantity, certification, approval, availability or price. Every commercially meaningful value is taken from producer documentation for the exact grade offered and confirmed in writing before order.
Sourcing and origin+
Allzone sources seaweed-derived hydrocolloids through producer channels and quotes them per enquiry. Origin is selected against your technical requirement, quantity, documentation need and destination, and is stated in the offer rather than fixed by this page.
Documentation supplied with an offer+
Technical data sheet, safety data sheet and certificate of analysis for the exact grade offered are requested from the producer and shared with the quotation. Where a declaration matters to your application — food contact, pharmaceutical or cosmetic use, allergen, kosher or halal — it is confirmed for that specific grade and intended use rather than assumed from this page.
How Allzone quotes this+
Send the functional target, the application, the quantity, the destination and the documentation you need. Several hydrocolloids can be listed in one enquiry and reviewed together rather than split into separate requests.
Frequently asked questions
Does Allzone publish a price for alginic acid?+
No. Price, minimum quantity, origin, packing and lead time depend on the grade, the volume and the destination, and are confirmed at quotation. Nothing on this page is an offer.
Which grades or presentations of alginic acid can be quoted?+
Powder presentation, Granular presentation, Food, pharmaceutical or cosmetic documentation are handled inside this single product record. Grades of one material are not published as separate pages; the grade offered and its published data are confirmed in the quotation.
What documentation is available for alginic acid?+
Technical data sheet, safety data sheet and certificate of analysis for the exact grade offered are requested from the producer and shared with the quotation. Where a declaration matters to your application — food contact, pharmaceutical or cosmetic use, allergen, kosher or halal — it is confirmed for that specific grade and intended use rather than assumed from this page.
Can alginic acid be supplied into Ontario and the GTA?+
Delivery and logistics into Ontario, Quebec and the rest of Canada are reviewed per enquiry alongside the rest of the offer. We publish no stock, inventory or delivery-window guarantee on this page.
