HIGHLY BIOAVAILABLE Na-ACYL ACIDIC AMINO ACID ESTER SALT COMPOSITONS WITH ZWITTERIONIC SURFACTANTS

摘要

The present invention provides compositions comprising from about 0.01 to about 3% by weight of the composition of one or more Nα-acyl acidic amino acid ester salts represented by the formula I:;;wherein R1 is an alkyl group having from 1 to 8 carbons, R2 is an alkyl group having from 6 to 30 carbons, n is from 1 to 6 and X− is an anion; a zwitterionic surfactant; an alcohol represented by R3—OH, wherein R3 is an alkyl group having from 2 to 6 carbons; an aqueous vehicle; and an oily component, wherein the composition has a pH of less than 7. Also provided are methods of inhibiting plaque in an oral cavity comprising the step of introducing a composition of the present invention into the oral cavity and dispensing devices containing compositions of the present invention.

主权项

1. A dispensing device comprising a container containing an oral care composition and a dispensing assembly associated with the container for dispensing the composition from the device through an orifice, said composition comprising:
a) one or more Nα-acyl acidic amino acid ester salts represented by the formula I:wherein R1 is an alkyl group having from 1 to 8 carbons, R2 is an alkyl group having from 6 to 30 carbons, n is from 1 to 6 and X− is an anion;
b) a zwitterionic surfactant; c) at least 40% v/v of the total composition of an alcohol represented by R3—OH, wherein R3 is an alkyl group having from 2 to 6 carbons; and d) an oily component comprising at least one essential oil, at least one flavor oil, or a combination of two or more thereof;wherein the composition comprises less than 30% v/v of water.
