Chemical Properties:
  1. Kelcoloid occurs as a white to yellowish colored, practically odorless and tasteless, fibrous or granular powder.
  2. Kelcoloid  is practically odorless and tasteless. The propylene glycol ester of alginic acid varies in composition according to its degree of esterification and the percentages of free and neutralized carboxyl groups in the molecule. For a detailed description of this compound refer to Burdock (1997).
  3. Kelcoloid is a stable material, although it will gradually become less soluble if stored at elevated temperatures for extended periods.
    Propylene glycol alginate solutions are most stable at pH 3–6. In alkaline solutions, propylene glycol alginate is rapidly saponified. Alginate solutions are susceptible to microbial spoilage and should be sterilized or preserved with an antimicrobial preservative. However, sterilization processes may adversely affect the viscosity of propylene glycol alginate solutions; see Sodium Alginate.
    The bulk material should be stored in an airtight container in a cool, dry place.
  1. Kelcoloid pharmaceutic aid (viscosity-increasing agent).
  2. Kelcoloid is a gum that is the propylene glycol ester of alginic acid, which is obtained from kelp. as compared to sodium alginates, it has reduced sensitivity to acid and calcium salts. it functions in acidic systems. it functions as a thickener, stabilizer, and emulsifier in beer, salad dressings, syrups, and fruit drinks.
  3. Kelcoloid extracted from brown seaweed, is reacted with propylene oxide to form propylene glycol alginate. Various grades may be obtained that differ in composition according to the degree of esterification and the percentage of free and neutralized carboxyl groups present in the molecule; complete esterification of alginic acid is impractical.
