An anionic surfactant of general formula (I) or general formula (II) or mixtures thereof, in which R represents hydrogen or a linear or branched alkyl, alkenyl, alkylaryl or alkenylaryl group having 5 to 25 C atoms, n represents a number from 1 to 21 and m represents a number from 0 to 20, the sum of n and m being less than 22, and X+ represents a charge-balancing cation. The invention also relates to a mixture of the anionic surfactant of general formula (I) and the anionic surfactant of general formula (II), obtainable by reacting a mixture of 3-hydroxymethylcyclopentanol monoalcoholates having secondary and primary alcoholate functions with an electrophilic alkyl, alkenyl, alkylaryl, or alkenylaryl derivative and the subsequent sulfation with a sulfating agent and optionally neutralization. The invention further relates to a method for producing the surfactant and to the use of the surfactant.

Anionic surfactants and washing and cleaning agents containing same

The invention relates to surfactants of general formula (I) in which R represents a linear or branched alkyl, alkenyl, alkylaryl or alkenylaryl group having 5-25 C atoms and Xrepresents a charge-balancing cation. The surfactants can be incorporated into detergents or cleaning agents, have excellent technological application properties and can be produced based on renewable raw materials.

Anionic surfactants and detergents and cleaning agents containing same

The invention relates to surfactants of general formula (I) in which Rand Rrepresent independently of one another represent H and SOwith the proviso that at least one of Rand Ris not H, n and m represent independently from each other numbers from 0-21 under the proviso that 4&#x3c;n+m&#x3c;26, and Xrepresents a charge-balancing anion. The surfactants can be incorporated into detergents or cleaning agents, have excellent technological application properties and can be produced based on renewable raw materials.

Surfactants with tetrahydrofuranyl system

Detergents and cleaning agents containing an anionic surfactant of general formula (I), in which n is a number from 5 to 21 and Xis a charge-balancing cation. Also disclosed are an agent or a use, characterized in that, in the compound of general formula (I), Xis selected from the group including the proton, alkali metal cations and the group NRRR, where R, Rand Rare, independently of one another, hydrogen, an alkyl group with 1 to 6 C atoms or a hydroxyalkyl group with 2 to 6 C atoms.

Detergents and cleaning agents having anionic surfactants consisting of renewable raw materials

An anionic surfactant of general formula (I) in which n and m are, independently of one another, numbers from 0 to 17 and 2&#x3c;n+m&#x3c;20, and Xis a charge-balancing cation. The invention also relates to a production method by way of: the acid-catalysed reaction of 2,5-bis(hydroxymethyl) tetrahydrofuran with an alkene having 5 to 22 C atoms in equimolar amounts, at an increased temperature; subsequent sulphation with a sulphating agent; and optional neutralisation by a subsequent reaction with XOHor XCO, where Xis an alkali metal cation or a group NRRR, in which R, Rand Rare, independently of one another, hydrogen, an alkyl group with 1 to 6 C atoms, or a hydroxyalkyl group with 2 to 6 C atoms. Detergents or cleaning agents containing&#x2014;the surfactant, and the use of same to improve the performance of the detergents or cleaning agents, are also disclosed.
