    Abstract: 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

    Abstract: Surfactant compositions comprising an alkoxylate, a sulfate, or ether sulfate of a C10-C12 monounsaturated alcohol are disclosed. The alkoxylate, sulfate, or ether sulfate may derive from undecylenic acid or undecylenic alcohol. Compared with their saturated analogs, the monounsaturated alkoxylates, sulfates, and ether sulfates are less irritating, making them valuable for personal care, laundry, cleaners, and other household applications. Microscopy studies show that the alkoxylates, sulfates, and ether sulfates have favorable phase behavior over a wide range of actives levels, expanding opportunities for products with greater compaction. When combined with cationic surfactants, the alkoxylates, sulfates, and ether sulfates exhibit synergy, and they have improved solubility compared with their saturated analogs. The surfactants find value for the personal care, laundry and cleaning, emulsion polymerization, agricultural products, oilfield applications, and specialty foams industries.

    Abstract: Disclosed are improved cleaning compositions comprising soap&com ma; fatty acid, synthetic detersive surfactant, salt and a polyhydridic alcohol, which are suitable for formation into precursor cleansing/laundry bar 'soap noodles,' personal cleansing bars and laundry detergent bars. The compositions comprise: (a) from about 58 % to about 93 % by weight of an approximately 70 % aqueous soap slurry; (b) from about 1 % to about 15 % by weight of a fatty acid; (c) from about 2 % to about 30 % by weight of an approximately 55 % aqueous mixture of anionic surfactants comprising i) an alpha sulfonated alkyl ester; and ii) a sulfonated fatty acid or salts thereof, wherein the ratio of i) to ii) is from about 10:1 to about 1:10; (d) from about 0.5 % to about 2 % by weight of a salt; (e) from about 0.5% to about 5 % by weight of a 25 polyhydridic alcohol; and (f) from 0 to about 10% by weight of an alkanolamide of the formula O CH3(CH2)n C NH(CH2)yOH wherein n = 6-16, and y is 2-4; The invention additionally relates to an improved process for producing both precursor cleansing/laundry bar 'soap noodles' and personal cleansing/laundry detergent bars 35 comprising combining (a) - (e) to form a liquid mixture at a temperature of about 65 °C to about 105 °C, removing from about 50% to about 90% by weight of the water from the liquid mixture, by heating up to 150 °C under vacuum conditions or 105 °C at normal conditions to form a thickened mixture, extruding the thickened mixture to form flaked solid or semi-solid pellets or noodles, and optionally, plodding the flaked solid or semi-solid pellets or noodles to form plodded pellets or noodles,f extruding the plodded pellets or noodles to form a billet, cutting the billet, and stamping the cut billet to yield a personal cleansing/laundry detergent bar.
