    Abstract: Compositions comprising at least one esteramine active are disclosed in which the esteramine provides conditioning, softening, and/or cleaning properties. The compositions are useful for hair care, as well as in other applications, such as cleaning compositions, fabric softening compositions, and skin care compositions. Also disclosed are esteramine compositions that comprise a synergistic mixture of at least one esteramine and mono- and di-glycerides that provides better wet and dry combing than either the esteramine or mono- and di-glycerides alone. The synergistic mixture comprises about 50% to about 90% by weight esteramines and about 10% to about 50% by weight mono- and diglycerides.

    Abstract: 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 C14-C30 alkyl chain and a polar group bonded to a central zone carbon of the alkyl chain. The alkylene-bridged surfactant has a C12-C18 alkyl chain, a polar group, and a C1-C2 alkylene group bonded to the polar group and a central zone carbon of the C12-C18 alkyl 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.

    Abstract: Methods for making efficient use of steam in a steam-assisted gravity drainage (SAGD) process for recovering heavy oils from tar sands and similar petroleum deposits are disclosed. The methods utilize a surfactant to generate steam foam in ways that maximize efficient use of steam. In some aspects, steam foam is used in water layers or gas caps that reside above steam chambers to prevent loss of steam from the steam chamber. The predominant use of relatively dry steam in SAGD processes makes it challenging to find ways to introduce surfactants and generate steam foam. However, decreasing the mobility of the steam by converting at least some of it to foam allows the wellbore and steam chambers above the injection site to be more fully developed, provides for more effective heat transfer to the heavy oil and rock, improves production, and allows recovery of the heavy oil with a minimum amount of steam usage.

    Abstract: 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 C14-C30 alkyl chain and a polar group bonded to a central zone carbon of the C14-C30 alkyl chain. The alkylene-bridged surfactants comprise a C12-C18 alkyl chain, a polar group, and a C1-C2 alkylene group bonded to the polar group and a central zone carbon of the C12-C18 alkyl 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.

    Abstract: Personal cleansers and surfactant blends useful therein are disclosed. The cleansers comprise a primary anionic surfactant, a saturated C8-C-14 alkyl N,N-dialkylamide, and water. The cleansers have good foaming properties and improved viscosity build profiles compared with cleansers that rely on alkanolamides or betaines as the secondary surfactant. The saturated C8-C14 alkyl N,N-dialkylamides are water-white liquids that solubilize cleanser components well, including high levels of fragrances, and can be formulated easily without heating at any actives level up to 100%. Importantly, the surfactant blends build viscosity with less added salt compared with alkanolamide or betaine-based blends, even with more challenging anionic surfactants. Moisturizing cleansers disclosed herein have excellent flash foaming character, foam volume, and foam feel and provide a luxurious, lotion-like after-feel. The personal cleansers include, among others, shampoos, body washes, facial cleansers, shower gels, liquid soaps, hand soaps, baby liquid cleansers, pet shampoos, and bubble baths. The fatty N,N-dialkylamides are also valuable for formulating oil-in-water emulsions with good stability.
