Potassium Alginate

Potassium alginate is used as a gelling agent where a calcium source is present, and as a thickener, stabiliser and bulking or binding agent where it is not. In food it contributes texture and suspension; in cosmetic and personal care formulations it is used for viscosity and film behaviour; in pharmaceutical formulation and in pet food or feed it appears as a binder and structuring aid. Allzone makes no medical or efficacy claim for this material — suitability for any regulated use is confirmed for the specific grade and intended application.

Viscosity type and particle size are the first decisions: they set hydration rate, dispersibility and the texture the finished system reaches. After that, whether you are gelling with a calcium source or simply thickening, the pH of the system, the process temperature and the documentation your sector requires decide the grade quoted.

Sodium alginate is the most widely used alginate salt and has its own canonical page on this catalogue; potassium alginate is the potassium counter-ion equivalent and is selected for formulation reasons rather than as a generic substitute. Alginic acid is the free acid form and is a separate record, as is propylene glycol alginate, the esterified derivative. Moulding alginate for lifecasting is a formulated impression product, not a raw alginate salt, and remains a distinct page. Carrageenan and agar are different seaweed hydrocolloids entirely.

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.

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.

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.

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.
