Tricarballic acid

Synthetic, fat-tike substances Lhat arc resistant to hydrolysis by digestive enzymes. One type is a mixture of the hexa-to-octaesters of sucrose others are esterified propoxylated glycerols and dialkyl dihexadecylmalonate (DDM), which has been used in potato and tortilla chips trialkoxytricarbaliate-tricarballic acid esterified with fatty alcohols, currently under trial for use in margarine- and mayonnaise-type products. 

There is confusion in the literature concerning the nature of the polymers used in glass-ionomers. This stems from the early research of Wilson et al., who studied a range of mono-, di- and tri-carboxylic acid monomers in polymers for cement formation, including itaconic and tricarballic acid [20] and this has led to the assumption that these must be used in practical cements. In fact proprietary materials are all based on the two polymers previously mentioned.
