A surfactant composition includes a homogeneous mixture of greater than 70%, by weight, of N-acyl alaninate surfactant of formula (I) and an N-acyl amino acid surfactant of formula (II). A process for preparation of a blend of an N-acyl alaninate surfactant and an N-acyl amino acid surfactant includes combining (a) an alanine amino acid and (b) other amino acid, an anhydrous alkali salt of the other amino acid, or both, a waterless base, and a fatty alkyl ester of formula (V) to form a mixture including alanine amino acid salt of formula (III), and other amino acid salt of formula (IV). The process further includes increasing the temperature of the mixture to 180° C. or less to form a reaction mixture. The process further includes continuously removing alkyl alcohol from the reaction mixture and allowing the reaction mixture to become substantially clear to form the blend.

According to the invention, the compositions and methods provide for the complete removal of labels, synthetic glues and/or adhesives from a plurality of surfaces through the use of an aqueous or non-aqueous basic organic solvent and/or an amidine, optionally in combination with surfactants, chelants, acidulants and/or additional bottle wash additives. Beneficially, the compositions and methods are suitable for use at lower temperatures and pH conditions, along with under caustic-free and/or reduced caustic conditions to effectively remove such labels, synthetic glues and/or adhesives from a surface within less than about 30 minutes.

Liquid detergent compositions can be stably structured using amides of an aliphatic polyamine with two, three or four molecules of fully saturated hydroxyl alkyl acids, even in the presence of hydrolysing detergent ingredients such as lipase enzyme.

Water-soluble refill dose articles for forming a cleanser have a water-soluble film defining a first compartment enclosing a first composition and a second compartment enclosing a second composition, which are individual separate articles or are part of an integral article. The first composition has a rheology modifier, a first surfactant, 10% or less by weight water, 20% or less by weight glycol, and the first surfactant does not activate the rheology modifier. The second compartment has an alkaline substance that when mixed with the first composition and water activates the rheology modifier to increase the viscosity of a resulting cleanser and 10% or less by weight water. When the article is diluted in water at a 1:1 to 1:20 ratio, it produces a cleanser having a viscosity within a range of 2000 cps to 50,000 cps.

Aqueous hard surface cleaner compositions useful for removing permanent ink are disclosed. The compositions comprise 75 to 99 wt. % of water; 0.1 to 5 wt. % of a monoterpene; 0.1 to 5 wt. % of a C10-C17 fatty acid derivative; and 0.1 to 5 wt. % of one or more surfactants. The fatty acid derivative is selected from N,N-dialkyl amides, N,N-dialkyl esteramines, and N,N-dialkyl amidoamines. Preferably, a base such as sodium carbonate or monoethanolamine is also included. The invention includes concentrates comprising the non-aqueous components recited above, as well as other applications for the cleaners and concentrates such as graffiti removers and permanent ink erasers. The combination of a monoterpene and certain fatty acid derivatives, especially fatty N,N-dialkyl amides, unexpectedly enables even dilute aqueous compositions to rapidly decolorize black permanent marker from hard, non-porous surfaces.

Sanitizing cleaning/rinse aid compositions for various applications including institutional machine warewash sanitizing are disclosed. In particular, concentrated and use compositions, such as concentrated liquid rinse aid compositions or ware wash detergents, employing an amine-based surfactant and a defoaming agent are disclosed. In particular, the present disclosure provides compositions and methods for providing a sanitizing rinse with desired antimicrobial efficacy against a broad spectrum of gram-negative microbes, suitable foaming profiles, and beneficial applications of use of the same.
