The invention presented in this application relates to a fragrance deposition system for high surfactant applications such as shampoo and body wash. The system will provide a long lasting release of the fragrance and is more efficient at low levels and does not deposit particles that can cause adverse properties.

Deposition from surfactant systems

The present invention provides an efficient acid conversion process by which native and modified starches may be treated to afford products with low viscosity and a higher proportion of lower molecular weight compounds than the corresponding aqueous acid conversion processes. Such converted starches demonstrate unique properties and, accordingly, are useful in a variety of products.

Thermally converted starches and the method of preparation thereof

The present invention relates to biodegradable chemical compositions wherein core substrates, particularly oil well chemicals, are adsorbed onto particulate starch, particularly granular starch, providing a stable, controlled release formulation suitable for use in oil field applications. The invention further relates to the process of preparing obtaining these compositions.

Compositions for controlled release

A stable, solid product of selected starches, active agricultural agents and optionally surfactants and or adjuvants which is readily dispersible in aqueous medium and compatible when dispersed.

Water dispersible starch based physical form modification of agricultural agents

The present invention is directed to a low VOC, non-aerosol, polyacrylic acid containing hair cosmetic compositions which contain stabilized starches, particularly those derivatized by alkylene oxides, about 01.-0.0% polyacrylic acid, up to about 15% solvent, and water. The derivatized starch may be hydrolyzed, particularly enzymatically hydrolyzed by at least one endo-enzyme. In addition, the starch may be cationically modified with a low degree of substitution. Use of such starches is novel and advantageous in that they are compatible with polyacrylic acid, providing a clear, solution with a stable viscosity. Further, the resultant composition provides a clear film which is not tacky, good stiffness, and improved humidity resistance.

Use of stabilized starches in low VOC, polyacrylic acid-containing hair cosmetic compositions

Selectively cross-linked starches are disclosed that are useful as fluid loss control additives in subterranean treatment fluids comprising starches that cross-linked to a Brabender peak viscosity of about 800 to about 1250 Brabender units after about 40 to about 70 minutes at about 92&deg; C. and provide good fluid loss control over a temperature range of from about 20&deg; C. to about 160&deg; C. (68&deg; F. to 320&deg; F.).

Method of controlling loss of a subterranean treatment fluid

The present invention is directed to low VOC, non-aerosol hair cosmetic compositions, which contain nonionically modified starches. The starch may be additionally hydrolyzed, particularly enzymatically hydrolyzed. Further, the starch may be modified using ionic substituents. Use of such starches is novel and advantageous in that they provide a clear solution with a low viscosity, and good pump spray characteristics. Further, the resultant composition provides a clear film which is not tacky, good stiffness, and improved humidity resistance.

Nonionically derivatized starches and their use in non-aerosol, low VOC hair cosmetic compositions

An aqueous, light weight paper laminating adhesive comprising a continuous aqueous phase of from about 15 to 50% by weight of polysaccharide material dispersed in water, the continuous phase polysaccharide material having a zero-shear viscosity of greater than 0.07 Pa&middot;s when measured at 26% (&plus;/&minus;1% solids) and a shear rate of 0.1s ; a shear-thinning index of 0.90 to 1.1; and bleed time of greater than 15 seconds. Also disclosed is another adhesive composition, which is particularly useful in non-contact spay applications and comprises the continuous phase polysaccharide phase described above as well as a second component comprising a water swellable, insoluble polysaccharide particulate phase.

Polysaccharide adhesives for multi-ply paper products

The present invention is directed to low volatile organic compound aerosol hair cosmetic compositions which contain nonionically derivatized starches optionally hydrolyzed and/or ionically modified, about 5-55% propellant, up to 50% solvent, and water. Such compositions provide a clear solution with a low viscosity, good spray caracteristics, a clear, non-tacky film, good stiffness, and improved humidity resistance.

Aerosol hair cosmetic compositions containing non-ionically derivatized starches

Stable, cold water soluble, ready for use starch aldehyde compositions and the method of preparation of such compositions wherein an aqueous dispersion of a converted starch acetal is hydrolyzed under acidic conditions to form the starch aldehyde which is then spray dried into a cold water soluble starch aldehyde powder.

Cold water soluble starch aldehydes and the method of preparation thereof

This invention involves skin cleaning products and tapes for removing keratotic plugs, dirt and other debris found on the skin and in skin pores and comprising a starch based remoistenable adhesive composition wherein the starch has from about 0 to 70% by weight amylose content and is converted to from about 30 WF to 20 DE.

Starch based adhesives for skin cleaning tape

Selectively cross-linked starches are disclosed that are useful as fluid loss control additives in subterranean treatment fluids comprising starches that are cross-linked to a Brabender peak viscosity of about 800 to about 1250 Brabender units after about 40 to about 70 minutes at about 92&deg; C. and provide good fluid loss control over a temperature range of from about 20&deg; C. to about 160&deg; C. (68&deg; F. to 320&deg; F.).

Fluid loss control additives and subterranean treatment fluids containing the same

Polysaccharide based thermosetting systems and compositions which utilize such thermosets are disclosed. The composition comprises a polysaccharide having a weight average molecule weight of at least 10,000 and a polycarboxylated polymer having at least two carboxylic acid functional groups and a weight average molecular weight of at least 1,000.

Thermosetting polysaccharides

Thermally-inhibited starches and flours are used in cosmetic compositions such as skin and hair care products as emulsifiers, thickeners, and aesthetic control agents. The starch or flour is inhibited by dehydrating the starch or flour to anhydrous or substantially anhydrous and then heat treating the dehydrated starch or flour for a time and at a temperature sufficient to inhibit the starch or flour and improve its viscosity stability when dispersed in water. The dehydration may be a thermal or a non-thermal dehydration (e.g., by alcohol extraction or freeze-drying). Preferably, the pH of the starch or flour is adjusted to a neutral or above (e.g., pH 8-9.5) prior to the dehydration and heat treatment.

Cosmetics containing thermally-inhibited starches

Cosmetic compositions useful in skin care are provided containing an effective aesthetic enhancing amount of calcium salt starch derivatives having the following formula: ##STR1## where ST is the starch base material, R is a dimethylene group and R' is a substituent hydrocarbon group having 10 to 16 carbon atoms.

Cosmetic compositions containing hydrophobic starch derivatives
