  • Patent number: 11981879
    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.

  • Patent number: 11760889
    Abstract: Sulfate and sulfonate derivatives of unsaturated fatty alcohols, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester. The fatty alcohol composition is then converted to a sulfate or sulfonate derivative by one or more of alkoxylation, sulfation, sulfonation, and sulfitation. Of particular interest are the sulfate and ether sulfate derivatives. Microscopy studies indicate that the unsaturated sodium sulfates in particular have a lamellar phase that should enable formulation at high actives levels. Sulfate compositions comprising 40 to 60 wt. % of a monounsaturated fatty primary alcohol sulfate and 40 to 60 wt. % of a secondary hydroxyalkyl primary alcohol sulfate are also disclosed.

  • Publication number: 20230242475
    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.

  • Publication number: 20230030812
    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.

  • Patent number: 10781405
    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.

The amine reactant can be diethylenetriamine or (2-aminoethyl)ethanolamine, which provide imidazoline amides or esters, respectively. In one aspect, the ester derivative of the C10-C17 monounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin.

  • Patent number: 9708251
    Abstract: Unsaturated fatty alcohol alkoxylates, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol alkoxylate is made by reducing a metathesis-derived monounsaturated alkyl ester, followed by alkoxylation of the resulting monounsaturated alcohol. Microscopy reveals that the monounsaturated alkoxylates have isotropic and lamellar phases over a wider range of actives levels compared with their saturated analogs. This attribute expands formulating latitude for many end-use applications. The unsaturated fatty alcohol alkoxylates are valuable in, for example, agricultural solvents, nonionic emulsifiers for agricultural compositions, hard surface cleaners, laundry detergents, specialty foams, additives or surfactants for paints or coatings, and surfactant compositions for enhanced oil recovery.
