A quaternary nitrogen-containing corrosion inhibitor of formula wherein is an aromatic, nitrogen-containing ring of 5 to 14 ring atoms, optionally containing an additional N, O or S ring atom and optionally substituted with one or more alkyl, alkenyl, aryl, arylalkyl, cycloalkyl, amino, aminoalkyl, alkoxy, hydroxylalkyl, or cyano groups, or a mixture thereof; Y is a group of formula &#x2014;OC(O)Ror &#x2014;C(O)R; L is C-Calkyl, C-Calkenyl or a group of formula &#x2014;CHCH(OR)CH&#x2014;; Ris C-Calkyl or C-Calkenyl; Ris H or &#x2014;C(O)R; Rand Rare independently selected from H, alkyl, alkenyl, amino, alkoxy, hydroxylalkyl and cyano; and X is Br, Cl or I is particularly useful for inhibiting corrosion in oil and gas field applications.

Mono and bis-ester derivatives of pyridinium and quinolinium compounds as environmentally friendly corrosion inhibitors

A hair treatment composition for straightening hair. The composition comprises: i) 0.1 to 7.9 wt % of the total formulation of a sugar lactone; and ii) cationic surfactant of formula (1): [N(R)(R)(R)(R)]+(X)in which R, R, R, and Rare independently selected from (a) an aliphatic group of from 1 to 22 carbon atoms, or (b) an aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl group having up to 22 carbon atoms; and X is a salt-forming anion selected from halogen, acetate, citrate, lactate, glycolate, phosphate nitrate, sulphate, and alkylsulphate.

Hair treatment composition comprising sugar lactone

An aqueous hair treatment composition comprising: a) from 0.01% to 10% by weight of the total composition of beeswax; and b) from 0.01% to 10% by weight of the total composition of a sugar lactone.

Environmentally friendly compounds for corrosion inhibition and hydrocarbonaceous deposit removal and methods using such compounds are disclosed and claimed. The compounds are derivatives of heterocyclic bis-quaternary molecules having an amido moiety and are applicable to a variety of oil and gas operations.
