Detergents useful for cold-water cleaning and mid-chain headgroup and alkylene-bridged surfactants useful therein are disclosed. The mid-chain headgroup surfactant has a C-Calkyl chain and a polar group bonded to a central zone carbon of the alkyl chain. The alkylene-bridged surfactant has a C-Calkyl chain, a polar group, and a C-Calkylene group bonded to the polar group and a central zone carbon of the C-Calkyl chain. Preferred surfactants in these classes are alcohol sulfates, alcohol ethoxylates, ether sulfates, sulfonates, arylsulfonates, alcohol phosphates, amine oxides, quaterniums, betaines, and sulfobetaines. Surprisingly, detergents formulated with the surfactants provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.

Detergents for cold-water cleaning

Laundry detergents and their use for cold-water cleaning are disclosed. The detergents comprise a lipase and a mid-chain headgroup surfactant or an alkylene-bridged surfactant. The mid-chain headgroup surfactants have a C-Calkyl chain and a polar group bonded to a central zone carbon of the C-Calkyl chain. The alkylene-bridged surfactants comprise a C-Calkyl chain, a polar group, and a C-Calkylene group bonded to the polar group and a central zone carbon of the C-Calkyl chain. Surprisingly, when combined with lipases, detergents formulated with the mid-chain headgroup or alkylene-bridged surfactants effectively liquefy greasy soils at low temperature and provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.

Cold-water laundry detergents

Provided are alkyl lactyllactate compositions that can be prepared from (1) lactide or alternatively lactic acid, and (2) a hydroxyl containing compound such as an alcohol, preferably a fatty alcohol or an alkoxylated alcohol, with (3) an acid catalyst. Preferably, the fatty alcohol contains from about 6 to 18 carbon atoms, such as lauryl alcohol. The alkyl lactyllactates can be used as surfactants, emulsifiers, skin feel agents, film formers, thickeners, rheological modifiers, etc., for personal care and other application areas. Compositions containing at least one alkyl lactyllactate are also provided. The compositions can further contain at least one surfactant.

Alkyl lactyllactates and processes of making the same

Compositions comprising sulfo-estolides and alkyl ester sulfonates are described. Detergent formulations, such as laundry detergents, softeners, and other materials, containing any of these materials are disclosed, as well as personal care formulations, hard surface cleaner formulations, and automatic dishwasher detergent formulations. Laundry methods employing these formulations are also disclosed. These formulations are useful as laundry detergents and can be biodegradable, heavy duty liquids, 2&#xd7; or 3&#xd7; and up to 6&#xd7; concentrates, low foaming, and/or effective in a high efficiency washing machine.

Compositions comprising sulfonated estolides and alkyl ester sulfonates, methods of making them, and compositions and processes employing them

Formulations of personal care compositions and personal care concentrate compositions containing sulfo-estolides are described. Personal care compositions of the present technology include liquid hand soaps, bath and shower washes, shampoos, 2-in-1 or 3-in-1 shampoos, antidandruff shampoo, facial cleaners, among others.

Personal care compositions of sulfonated estolides and other derivatives of fatty acids and uses thereof

A personal cleansing composition exhibiting enhanced skin feel (i.e., enhanced skin softness, reduced skin irritation, reduced residue, and reduced greasy, tacky, or tight skin feel), enhanced foaming and lather, and good cleansing, more specifically, a personal cleansing composition comprising a mixture of alpha sulfonated alkyl esters or sulfonated fatty acids, or salts thereof, with an alkyl sulfoacetate or ethoxylated alkyl sulfoacetate, or salts thereof, secondary surfactants, and optional additives.

Liquid cleansing composition comprising a ternary mixture of anionic surfactants

Disclosed are low solids and high viscosity fabric softener compositions and processes for preparing them. The composition contains from about 0.05% to about 10% by weight of a rheology modifying fabric softening active comprising at least one long chain amine of the present technology, a derivative thereof, or a mixture thereof, and from about 1% to 10% by weight of an additional fabric softening active dispersed in water.

Water-in-oil emulsions containing increased amounts of oil and methods for preparing same

Disclosed are hair care compositions and methods for preparing such compositions which provide the benefits of cleaning, conditioning, curl retention, styling and setting properties simultaneously to hair in the application of a single product. The hair care compositions contain fatty alkyl amine salts, long chain quaternary ammonium salts and mixtures thereof of anionic styling polymers in a non-anionic surfactant system, wherein the surfactant system contains nonionic surfactants, semi-polar nonionic surfactants, amphoteric surfactants and mixtures thereof. The styling, setting and conditioning agents are present in the form of fatty alkyl amine salts or fatty quaternary ammonium salts which form anionic styling polymer particulate networks upon dilution in water. These networks are dispersed in the aqueous non-anionic surfactant system and are stabilized and thickened by optional swellable polymer thickening agents. Hair care compositions of the present invention can be made in the form of structured liquids, pearlescent/opaque isotropic liquid and/or translucent/clear isotropic liquids. The hair care compositions of the present invention, which allow for re-styling of the hair by wetting the hair with water, contain no anionic surfactants, silicones, solvents or cationic polymeric conditioning agents. Furthermore, multiple application of these hair care compositions does not produce a noticeable build-up on the hair.
