Appl. No.:

17/976315

Inventors:

- Northbrook IL, US
Kathryn E. Merwin - Palatine IL, US
Teresa Germain - Orland Park IL, US
Patrick Shane Wolfe - Palatine IL, US

International Classification:

C11D 1/62
C11D 3/00
C11D 3/43
C11D 3/32
C11D 3/37
C11D 11/00

Abstract:

Clear, stable concentrated liquid compositions are disclosed that comprise from 30% to 90% by weight of an esterquat active, and from 10% to 50% by weight of a particular solvent system. The esterquat active is the quaternized reaction product of a fatty acyl source having an Iodine Value of 40 to 130 reacted with an alkanolamine at a fatty acyl to alkanolamine molar ratio of 1.0:1 to 2.2:1. The concentrated liquid compositions have a VOC content of less than 5%, a Biorenewable Carbon Index (BCI) of at least 20 and a viscosity of less than 5000 cP at 25 C. The concentrated liquid compositions can be easily diluted in water to form stable aqueous dispersions.

C11D 17/00

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.

International Classification:

C11D 3/37

Abstract:

Detergent compositions comprising one or more surfactants and a polyetheramine composition are disclosed. The polyetheramine composition comprises a compound having a polyglycerol core and an aminoalkyl group or an oxidized aminoalkyl group that is bonded directly or indirectly to each available oxygen of the polyglycerol core. Optionally, oxyalkylene groups link available oxygens of the polyglycerol core to the aminoalkyl or oxidized aminoalkyl groups. Methods for laundering textile articles and other cleaning methods using the detergent compositions are also disclosed. The polyetheramines can use diglycerol, a convenient plant-based starter. Laundry detergents comprising the polyetheramines provide enhanced cold-water cleaning performance for greasy or oily stains compared with similar detergents formulated without the polyetheramines.

International Classification:

C09D 133/12

Abstract:

A film may be formed from film forming compositions which comprise at least one carboxamide based coalescing solvent. These coalescing solvents impart equivalent or improved wet-scrub resistance, block resistance, gloss, dirt pick-up resistance and leveling characteristics to the films on a substrate, without contributing to total VOC levels, when replacing conventional coalescing solvents. The present invention also includes a method for forming a film comprising applying a film forming composition comprising polyunsaturated reactive carboxamides to a substrate and curing the film under ambient conditions. The coalescing carboxamide solvents are suitable for paint, latex based caulk, adhesives and floor care applications.
