Abstract: A lime soap dispersant comprising a polyester represented by the general formula:
wherein A represents a —CO— group, R1 represents a C2-4 alkylene group, R2 represents a C3-4 alkylene group, R3 represents a phenylene group, naphthylene group or biphenylene group, R4 represents a C2-8 alkylene group, R5 represents a C2-8 alkylene group, R6 represents a phenylene, naphthylene or biphenylene group which may be substituted with a —SO3M or —COOM group, X represents H, a C1-4 alkyl group, —R7SO3M group, —R8COOM group or —C(O)R9 group, M represents H or water-soluble cation, and R7, R8 and R9 independently represent a C1-4 alkyl group, m1 and m2 are independently a number of 0 to 25 while m1+m2 is 3 to 25, n1 is a number of 1 to 40, n2 is 0 to 5, n3 is 1 to 40, n4 is 1 to 10, n5 is 0 to 5, and n6 is 1 to 40.
Abstract: Disclosed are compositions suitable for formation into mild personal cleansing or laundry detergent bars, as well as other uses. The compositions generally comprise:
(a) from about 30% to about 99% by weight of a mixture of anionic surfactants comprising:
i) an alpha sulfonated alkyl ester; and
ii) a sulfonated fatty acid;
(a) from about 0.5% to about 50% by weight of a fatty acid; and
(b) from about 0.1% to about 50% by weight water;
wherein the ratio of i) to ii) is from about 10:1 to about 0.5:1, and wherein the ratio of (a) to (b) is about 1:1 to about 11:1.

Abstract: A composition of super molecule active solid cleaning agent manufactured from super molecules and inorganic chemicals consisting of suitable amounts in weight percent of an anionic surface active agent, a sodium carbonate, a sodium silicate, a fluorescent whitening agent, a carboxymethyl cellulose, a non-ionic surface active agent, a di-sodium edetate, an oleic acid and an essence. Water molecules can be activated by the active solid particles as they are immersed in the water. The active solid particles may rub with each other to generate excessive amount of negative hydroxyl ions (OH) in water. Accordingly, the pH value in water increases and the water molecules are activated. As a result, the activated molecules of water may readily penetrate into the tissue of the fabric to weaken and soften the connection between the dirt and tissue of the fabric. The dirt attached to fabric can be readily removed.
