Disclosed is a propylene glycol hyaluronate ester having an esterification degree of 10-90% and a limiting viscosity of less than 3 dL/g.

The method is particularly suitable for the esterification of (poly)fatty acids or (poly)hydroxyfatty acids to esters with a high degree of esterification and low colouration.

Propane-1,2-diol ester of alginic acid; varies in composition according to its degree of esterification and the percentage of free and neutralised carboxyl groups in the molecule

This aqueous pectin solution contains pectin having a degree of esterification of 5-15% and a viscosity-average molecular weight of 10000-35000.

Propane-1,2-diol ester of alginic acid; varies in composition according to its degree of esterification and the percentage of free and neutralised carboxyl groups in the molecule

Disclosed is a skin-protecting alkalinity-controlling composition comprising an alkylene oxide derivative of pectin having a degree of esterification in the range from about 30% to about 100%.

The acidified pectin includes a low ester pectin with a degree of esterification of about 30 to about 50 and a pH of about 2 to about 4.

As the pectin, preferably, a high-methoxyl pectin with an esterification degree of 50% or more or a sugar beet pectin derived from beets is used.

Modified Citrus Pectin is comprised of short, slightly -branched carbohydrate chains derived from citrus fruit peels alter by decreasing the molecular weight and degree of esterification.

The ratio by weight of modified starch to propylene glycol alginate is about 60:40 to about 95:5; and the propylene glycol alginate has a degree of esterification of about 40 % to about 95 %.

In fact, Pectasol® is designed to have uniform molecular weight (between 10,000 and 20,000 daltons), a low degree of esterification (10% maximum) and the right pH for optimal absorption.
