  • Patent number: 7612136
    Abstract: An anionic surfactant concentrate and method for making includes providing compound (I) R1—OH where R1 represents a branched C6-22 radical with average branching of about 2-8 per radical; providing compound (II): where R2 represents a C8-16 radical; mixing (I) and (II); ethoxylating to obtain a reaction product; reacting with a sulfating, phosphating, or sulfitation agent to obtain R1—O—[CH2—CH2O]n-A and where R1 represents a branched C6-22 radical with average branching of about 2-8, R2 represents a C8-16 radical, A represents —SO3M, —PO3M, —PO3M2, —OCCH2CH(SO3Na)COO—, or HOOCCH2CH(SO3Na)COO—, M represents a positive counterion, n represents a value from 0-100, and x and y each represents a value from 0-100, where the sum of x and y represents a value of at least 1 to 100 are provided. Anionic surfactant compositions containing the concentrate and methods for stabilizing are also provided.

  • Publication number: 20080176997
    Abstract: A surfactant concentrate including a compound according to general formula (III): R1—O—[CH2—CH2O]n—H, and a compound according to general formula (IV): is provided. A liquid, surfactant composition including the surfactant concentrate in water is also provided. A surfactant concentrate and a liquid, surfactant composition including a compound according to general formula (V): R1—O—[CH2—CH2O]n—A and a compound according to general formula (VI): are also provided. Methods for stabilizing an emulsion polymer or polymer dispersion, and for adding to an emulsion polymer reaction or a polymer dispersion to carry out the polymerization reaction, are also provided.
