    Abstract: Compositions comprising at least one dialkyl amino acid ester salt as a cationic active are disclosed. The compositions are useful for hair care, as well as in other applications, such as cleaning compositions, fabric softening compositions, and skin care compositions. The dialkyl amino acid ester salts are derived from the esterification reaction of an amino acid having at least two carboxylic acid groups with a fatty alcohol, wherein the amine group of the amino acid is protonated with an acid. The compositions may further include a glyceride component comprising monoglycerides, diglycerides, or a combination thereof.

    Abstract: Compositions comprising a synergistic mixture of at least one neutralized amino acid ester and a glyceride component as a composition active are disclosed. The mixture comprises from 35% to 85% by weight neutralized amino acid ester, and from 15% to 65% by weight of a glyceride component comprising selected monoglycerides, diglycerides, or a combination thereof. The compositions are useful for hair care, as well as in other applications, such as cleaning compositions, fabric softening compositions, and skin care compositions. When formulated into a hair care formulation, the compositions provide better wet combing than either the neutralized amino acid ester or the glycerides alone. Also disclosed are end use compositions comprising the mixture of neutralized amino acid ester and selected glycerides.

    Abstract: Dilutable concentrates useful for hard surface cleaners with improved film/streak performance on high-energy surfaces are disclosed. The concentrates comprise a nonionic alkoxylated surfactant and a polyetheramine. A relatively minor proportion of a polyetheramine can resolve film/streak issues that characterize hard surface cleaners formulated with nonionic surfactants. The efficacy of polyetheramines for improving film/streak performance of hard surface cleaners formulated with nonionic alkoxylated surfactants far exceeds the benefits available from known improvements, such as the use of hydrotropes. Other inventive dilutable concentrates and hard surface cleaners comprise an amine-functional hydrophobe and an auxiliary surfactant. Still other dilutable concentrates or hard surface cleaners comprise a nonionic alkoxylated surfactant and lactic acid. An improved method for measuring film/streak properties of hard surface cleaners is also disclosed.
