A process is disclosed for making a solid composition comprising at least one quaternary ester ammonium compound and at least one substantially saturated fatty acid compound, a solid composition obtainable by that process, and a solid composition containing essentially more than 50 wt % of at least one quaternary ester ammonium compound, at most 50 wt % of at least one substantially saturated fatty acid compound, and less than 5.5 wt % of impurities.

Process for making solid compositions comprising quaternary ester

The invention relates to a solid composition comprising a hygroscopic amphoteric surfactant and a fatty acid which is substantially free from other detergents and/or detergent additives. Preferably, the fatty acid is a linear, saturated C.sub.6 -C.sub.22 acid. The weight ratio of amphoteric surfactant to fatty acid in said composition preferably is from 4:1 to 1:2. Examples of amphoteric surfactants include amine oxides and betaines. The solid composition of the invention may be shaped into a particulate form, such as granules. The invention further pertains to a process for preparing said composition and to the use of same, for example, in soap bars.

Fluidized bed coated amidoperoxyacid bleach composition

This disclosure relates to an aqueous peroxide composition with improved safety profile, the composition comprising a solid, substantially water-insoluble organic peroxy acid stably suspended in an aqueous medium, wherein the aqueous medium also comprises an effective amount of a safety booster selected from the group consisting of triethylene glycol, polyethylene glycol and mixtures thereof. The preferred organic peroxy acid is 1,12-diperoxydodeandioic acid. The aqueous peroxide composition is particularly useful in detergent, bleaching, cleaning and/or disinfecting formulations.

Aqueous peroxide compositions with improved safety profile

This disclosure relates to pourable bleaching compositions comprising a solid substantially water-insoluble organic peroxy acid stably suspended in an aqueous medium containing at least two polymers wherein the first polymer is selected from polysaccharides having at least 60% of the units in the polysaccharide backbone being linked together by a 1,4-.beta.-oxy linkage and the second polymer is selected from the group consisting of polyvinyl alcohol, one or more cellulose derivatives and mixtures thereof. The bleaching composition also may contain an electrolyte and/or a safety booster. The preferred organic peroxy acid is 1,12-di peroxydodecanedioic acid.

Stable pourable aqueous bleaching compositions comprising solid organic

A process for the preparation of salt granulates particularly useful as carrier media for liquid washing agent raw materials in detergent compositions of high bulk density. The process includes granulation under pressure of salt powder having a content of water of crystallization of at least 10% and an average particle size of 1 to 500 .mu.m, and subsequent extraction of the water of crystallization in a fluidized bed at a temperature of the bed which is below the melting point of the granulate. In the granulation process use is preferably made of a mixture of water of crystallization-holding salts and anhydrous salts.

Process for the preparation of salt granulates

The invention relates to bleaching granules containing a solid, water-insoluble peroxy acid and a hydratable inorganic material. The bleaching granules are made by a process wherein the constituents to be used are mixed to form a powder at low temperature and granules are formed from the powder as the temperature is increased to at least the hydration temperature of the hydratable inorganic material. The invention also relates to bleaching compositions and detergent compositions comprised of such bleaching granules.

Bleaching granules

This disclosure relates to pourable bleaching compositions comprising a solid substantially water-insoluble organic peroxy acid stably suspended in an aqueous medium containing at least two polymers wherein the first polymer is one or more natural gums and the second polymer is selected from the group consisting of polyvinyl alcohol, one or more cellulose derivatives and mixtures thereof. The bleaching composition also may contain an electrolyte. The preferred organic peroxy acid is 1,12-diperoxydodecanedioic acid. The preferred first polymer is xanthan gum. The second polymer is preferably a cellulose ether.

Stable, pourable aqueous bleaching compositions comprising solid organic

The invention relates to a process for the preparation of bleaching granules containing a solid, water-insoluble peroxy acid and a hydratable inorganic material, in which process the constituents to be used are mixed to form a powder at low temperature and granules are formed from the powder as the temperature is increased to at least the hydration temperature of the hydratable inorganic material. The invention also relates to bleaching compositions and detergent compositions comprised of such bleaching granules.
