Fatty alcohol phosphate ester emulsifier compositions

An oil-in-water emulsifier composition including between about 10 percent and about 70 percent by weight of a blend of mono- and diester phosphates of alkoxylated fatty alcohols containing between about 12 and 22 carbon atoms and alkoxylated with between about 1 and about 50 moles of an alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures thereof, wherein the mono- and diester ratio is between about 10:90 and about 90:10; and between about 90 percent and about 30 percent by weight of a blend of mono- and di-ester phosphates of fatty alcohols containing between 12 and 22 carbon atoms, wherein the mono- and diester ratio is between about 10:90 and about 90:10. Emulsifying waxes, oil-in-water emulsions and microemulsions, and topical compositions formulated therefrom are also disclosed.

Absolute viscosity and density of trisubstituted phosphoric esters

This paper presents measurements on the absolute viscosity (η) and density (ρ) of trisubstituted phosphoric esters which are useful in understanding their flow mechanism necessary for accessing their role as plasticizers. The effect of chain length and branching has been examined on the η and ρ trends. From η data, by using the Vogel-Tammann-Fulchur (VTF) equation, the VTF temperature (To) has been obtained which also represents the ideal glass transition temperature. To is related to the flexibility of the molecules. It is observed that To initially decreases with molecular weight, reaches a minimum, and increases thereafter. The initial decrease in To has been attributed to the enhanced flexibility of the phosphate esters. Reversal of flexibility with relative molar mass beyond 400 is due to the gentle collision of the arms of the trisubstituted phosphoric esters. This has been further corroborated from the molar mass exponent as exhibited in the η-molar mass plot. The isomeric effect on η has also been investigated in tricresyl phosphates, hitherto for the first time. The ortho isomer has highest η among the isomers. The para isomer was found to have lowest To and hence highest flexibility compared to the ortho and meta isomers.
