A process for preparing an opaque composition using ethylene glycol distearate including the steps of providing a starting composition including A) from 0.5 parts by weight to 15 parts by weight of at least one surfactant, B) from 0.5 parts by weight to 15 parts by weight of at least one emulsifier, C) from 10 parts by weight to 30 parts by weight ethylene glycol distearate, and D) from 20 parts by weight to 85 parts by weight water; b) stirring the starting composition at a temperature in a range from 60° C. to 100° C.; and c) cooling to a temperature in a range from 5° C. to 55° C. to obtain the opaque composition.

Opaque composition comprising ethylene glycol distearate

The invention relates to a process for preparing an opaque composition using ethylene glycol distearate.

The invention relates to compositions comprising

Hybrid quats in, in particular, hair treatment agents

The invention relates to cosmetic formulations comprising specific ester quats based on isopropanolamine or tetrahydroxypropyl ethylenediamine, and to the use of these ester quats in cosmetics.

The invention provides polyglycerol alkoxylate esters and for the preparation and use thereof.

Polyglycerol alkoxylate esters and preparation and use thereof

In a method for making a tris-(2-hydroxyethyl)-methylammonium methylsulfate fatty acid ester by quaternizing a tris-(2-hydroxyethyl)-amine fatty acid ester with dimethylsulfate the quaternizing is carried out in the presence of a solid acid scavenger. The method can provide a fabric softener active composition, comprising from 65 to 98% by weight of at least one tris-(2-hydroxyethyl)-methylammonium methylsulfate fatty acid ester, the corresponding non-quaternized tris-(2-hydroxyethyl)-amine fatty acid esters in amounts providing a total amine number of the composition of from 2 to less than 7 mg KOH/g, and from 1 to 1500 ppm methanol.

The invention describes novel silicone-containing graft copolymers and processes for their preparation. In particular, it relates to silicone-containing graft copolymers P, which are obtained by grafting olefinic monomers M onto polyether-containing radicals of polyoxyalkylene-polysiloxane block copolymers S with (AB)structure.

Silicone-containing graft copolymers of blockwise structure

The invention relates to novel polyester-polysiloxane block copolymers, to a process for their preparation and to the use of these polymers as a base oil or as an additive in lubricants, especially silicone oils.

Siloxane containing block copolymers, process for their preparation and their use for lubricants

The object of the present invention is to provide antifoams which have a good antifoam effect in aqueous dispersions of polymeric organic substances, cause no wetting defects when these dispersions are applied to a surface and at the same time retain their antifoam activity even after prolonged storage at temperatures down to the freezing point.

Use of grafted polyethersiloxane copolymers for improving the low-temperature stability of antifoams in aqueous dispersions
