    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.

    Abstract: N-Acyl amino acid salt compositions and an improved process for making them from fatty alkyl esters are disclosed. The process comprises reacting a fatty alkyl ester with an amino acid salt in the presence of an alkoxide catalyst at a pressure of at least 5 psig. At least 1 0 mole percent of catalyst is used based on the amount of fatty alkyl ester used as a reactant. Pressure and a minimum level of alkoxide catalyst are needed to give high fatty alkyl ester conversions and good yields of the desired N-acyl amino acid salt. The resulting N-acyl amino acid salt compositions have low color, an acceptable level of fatty acid soaps, and a small proportion of di-acylated by-products. Single-phase mixtures produced by combining various amino acid salts with glycinates, or by using an excess of either the fatty alkyl ester or amino acid salt, promote high conversions when the mixtures are reacted to give the desired N-acyl amino acid salt.

    Abstract: Improved processes for making an N-acyl amino acid salt from a fatty alkyl ester or a polyol ester are disclosed. Each process uses a polyol selected from glycerin or propylene glycol in an amount effective to keep the reaction mixture fluid until conversion to the N-acyl amino acid salt reaches the desired level of completion. In one process, a fatty alkyl ester reacts with an amino acid salt in the presence of glycerin or propylene glycol to produce an N-acyl amino acid salt. In another process, a polyol ester reacts with the amino acid salt in the presence of added glycerin or propylene glycol to produce the N-acyl amino acid salt. We surprisingly found that an effective amount of glycerin or propylene glycol minimizes or eliminates reaction mixture solidification or foaming, reduces color, and minimizes the level of di- and tripeptide by-products. In a related process, water is added when conversion of the amino acid salt to the N-acyl amino acid salt is in the range of 50 to 90 mole %. Water addition improves processability, advances conversion without producing excessive soap, and helps to ensure that the N-acyl amino acid salt will have low color and a small proportion of by-products.
