Surfactant
A surfactant of formula (I):
A-(L.sub.1).sub.a-(C.sub.2).sub.b-(L.sub.2).sub.c-X(I) wherein A is a perfluoropolyether; L.sub.1 is CONR', wherein R is selected from H and C.sub.1-6 alkyl; a is 0 or 1; b is 0 or an integer between 1 and 10; L.sub.2 is a linking group; c is 0 or 1; and X is a charged group.
Novel Mining Collectors
A family of amine mining collectors that uses alkoxylates allows for the easy adjustment of solubility and molecular weight useful because anionic and cationic mineral collectors require such varying degrees of solubility and molecular weight. The family of the present invention allows for the optimization of both parameters and an increase in collector efficiency.
BIOBASED SURFACTANTS UTILIZING CO2
Methods of generating a surfactant composition from natural oil and utilizing greenhouse gas in its manufacture are described. The methods involve the reaction of a lipophilic cyclic carbonate functionalized material with a functionalized amine to form the surfactant. The surfactant has a significant level of biobased carbon content and utilizes either petroleum-derived, biobased, or fermentation-derived greenhouse gas in its manufacture.

AMPHOTERIC ESTER SULFONATES
Disclosed are a variety of amphoteric ester sulfonates, including 3-(N, N-dimethyl-cocoylpropylammonio-1-yl)-2-hydroxypropanesulfonate. These amphoteric ester sulfonates can be advantageously prepared in high yield and purity by a two-step chemoenzymatic process, and have excellent surfactant properties.
Betaines with special fatty acid chain distribution
A subject-matter of the invention are betaines with a special fatty acid chain distribution, for example based on palm kernel oil, the palm kernel oil comprising an enhanced content of unsaturated C.sub.18 fatty acids.

Aqueous primary dispersions, process of their production and use thereof
The invention relates to aqueous, cationically stabilized primary dispersions comprising dispersed polymer particles having a Z-average particle diameter of 5 to 500 nm and which are obtainable by emulsion polymerization of at least one olefinically unsaturated monomer (A). The emulsion polymerization takes place in the presence of one or more emulsifiers (EQ) having the following general formula: R.sup.1N.sup.?(R.sup.2)(R.sup.3)(R.sup.4)X.sup.?, where R.sup.1 is a moiety with 15 to 40 carbon atoms which contains at least one aromatic group and at least one aliphatic group, and which contains at least one functional group selected from hydroxyl groups, thiol groups, and primary or secondary amino groups, and/or has at least one carbon-carbon multiple bond, R.sup.2, R.sup.3, and R.sup.4, independently of one another, are the same or different aliphatic moieties containing 1 to 14 carbon atoms, and X stands for the acid anion of an organic or inorganic acid. The invention further relates to a method for producing the primary dispersions, and to coating agents which include the primary dispersions, and to the use of the primary dispersions for producing electrodeposition coatings, and also to conductive substrates coated with the coating compositions. The invention further relates to emulsifiers which are used for producing the primary dispersions according to the invention.
