The present invention relates to isotropic liquids containing anionic polymers wherein the polymers are not hydrophobically modified and can still be incorporated into the compositions. By using anionic/nonionic compositions in which more than 25% of nonionic is sugar surfactant, the polymers can be incorporated without such modification.

Isotropic liquids incorporating anionic polymers which are not

The present invention relates to improved matrix or core shell enzyme capsule compositions comprising certain density modifying solids and defined core structural ingredients. Using these capsule compositions, much better active stability is obtained. In addition, higher active retention is accomplished during capsule formation. Release characteristics are not compromised. In a second embodiment of the invention, the invention relates to structured heavy duty liquid compositions comprising these capsules.

Matrix or core shell enzyme capsule compositions comprising defined

The present invention relates to isotropic liquids in which hydrophobically modified polar polymers having much higher ratios of hydrophile:hydrophobe than previously possible can be incorporated into the compositions. The compositions comprise greater than 17% to 85% surfactant and rate of hydrophile to hydrophobe on the polymers is greater than 7:1, preferably greater than 20:1, preferably 25:1 and up and most preferably no upper limit.

Isotropic liquids incorporating hydrophobically modified polar polymers

The present invention relates to liquid detergent compositions comprising linear or cross-linked, water soluble, highly salt-tolerant, nonionic polymers of MW 10,000 to 1,000,000 Daltons which, when added to structured heavy duty liquids makes the liquid highly shear thinning without decreasing pour viscosity of the composition or increasing it to a point where it is too thick. The compositions are also stable.

Structured liquid detergent compositions containing nonionic structuring

The present invention relates to a process for preparing matrix capsules having hydrocarbon cores sufficiently large to contain large size particle actives which process comprises dispersing actives in hydrocarbon core material, and dispersing the active containing hydrocarbon in a polymer solution to form a polymer matrix emulsion of drops of said core material in said solution. The key to the invention is to obtain the dispersion by utilizing low shear rates previously uncontemplated using the standard shearing machinery of the art. This in turn is accomplished by maintaining the core within defined rheological parameters. By using lower shear rates, applicants were unexpectedly able to prepare capsules capable of stably incorporating large size actives in the core.

Process for making polymer matrix capsules containing large hydrocarbon

The present invention relates to liquid detergent compositions comprising substantially linear, water soluble, highly salt-tolerant non-adsorbing, ionic polymers of MW 10,000 to 1,000,000 Daltons which, when added in defined minimum levels to structured heavy duty liquids, make the liquids highly shear thinning without decreasing pour viscosity of the composition or increasing it to a point where it is too thick. The compositions are also stable.

Liquid detergent compostions containing structuring polymers for

Isotropic liquid detergent composition comprises specific soil antiredeposition polymers containing a hydrophilic backbone and monomer with hydrophobic side chains. When the molar ratio of the number hydrophilic groups to number of hydrophobic groups on said polymers is below certain critical levels, it has been unexpectedly found that the stability (i.e., clarity) of the composition remarkably increases. The solubility of the polymer is further dependent on the type and amount (minimum required) of hydrotrope; surfactant type and levels; and minimum electrolyte levels.

Isotropic liquids comprising hydrophobically modified polar polymer

Isotropic liquid detergent composition comprises specific soil antiredeposition polymers containing a hydrophilic backbone and hydrophobic side chain; and aliphatic hydrocarbon oils. When the molar ratio of hydrophilic groups of the backbone to number of hydrophobic groups attached to the backbone is below certain critical levels; and aliphatic hydrocarbon oil of defined molecular weight (MW) range are incorporated in the formulation; it has been unexpectedly found that the stability (i.e., clarity) of the composition remarkably increases in such oil containing compositions.

Isotropic liquids comprising hydrophobically modified polar polymers

The present invention relates to a specific ternary enzyme stabilization system which unexpectedly enhances stability of a specific cellulase enzyme in isotropic liquid detergent compositions.

Heavy duty liquid detergent composition comprising cellulase

The present invention relates to heavy duty liquid composition in which solid particle or mixture of solid particles, wherein at least one side of solid has length or width of 3 to 25 microns, helps to suspend particles of much greater size (i.e., up to about 1000 microns) than possible w/o addition of the suspending solid particles.
