A method for enhancing the detergent properties of enzymes of an enzyme-containing detergent composition, comprising the step of adding to said composition an amphoteric polysaccharide.

Enzyme-containing detergent composition

The present invention relates to a non-cellulosic polysaccharide derivative:

Guar hydroxypropyltrimethylammonium chloride and uses thereof in hair treatment compositions

Products and processes that are related to phosphonated polysaccharide compositions, including phosphonated polysaccharide gels, having a substituent degree of substitution with a lower limit of 0.02 and an upper limit of 3, and having a weight average molecular weight with an upper limit of 5,000,000 g/mole, as well as to oil field application or fracturing fluid compositions comprising such phosphonated polysaccharide compositions.

Phosphonated polysaccharides and gels and process for making same

The present invention relates to an Automatic Dishwashing (ADW) detergent composition comprising at least one cationic polysaccharide of molecular weight of less than 1,000,000 g/mol. The invention also relates to a method for eliminating, limiting or preventing the spotting and/or filming phenomena during the washing comprising the use of a detergent composition according to claim

Detergent composition with anti-spotting and/or anti-filming effects

An aqueous fluid composition useful for the recovery of hydrocarbons from a subterranean formation, including a mixture of water, a water soluble polymer, an inorganic salt and at least one zwitterionic surfactant and methods of using same.

Addition of zwitterionic surfactant to water soluble polymer to increase the stability of the polymers in aqueous solutions containing salt and/or surfactants

Disclosed are soil additives comprised of self-situating, stimuli-responsive polymer compositions and methods of their use. In one embodiment, the polymer composition or polymer network comprises permanent cross-links and non-permanent cross-links, wherein the non-permanent cross-links are capable of being removed upon application or exposure to a stimulus, typically located within the soil. In another embodiment, the method of increasing water retention in soils includes applying a soil additive, comprising polymer networks of the present invention admixed with an aqueous solution to form a colloidal dispersion solution or suspension, to a soil surface. The suspension or colloidal dispersion solution facilitates penetration of the polymer composition through the soil surface and into the soil, migrating typically to lower water potential areas and, more typically, along drainage channels located within the soil. After penetration of the soil surface, the polymer network is then exposed to a stimulus, typically present in the soil, whereby the non-permanent cross-links are removed and the polymer composition undergoes a volumetric change. This results in the prevention, arrest or decelerated loss of water from the targeted area, for example the plant root zone, which allows for improved water usage efficiency by plants, grasses, vegetation, etc.

Compositions comprising a silyl-containing copolymer of a monomer system comprising:  

High definition printing with waterborne inks on non-porous substrates

An aqueous fluid useful for the recovery of crude oil from a subterranean formation, which includes a composition including a mixture of water, a water soluble block copolymer, an inorganic salt and at least one member of the group of a nonionic surfactant having an HLB of less than 12, and methods for using same.

Addition of nonionic surfactants to water soluble block copolymers to increase the stability of the copolymer in aqueous solutions containing salt and/or surfactants

A method for hydrophilizing a hydrophobic surface of a substrate includes the steps of (a) defining a temperature range of: (i) greater than or equal to an anticipated lower use temperature (LUT), or (ii) less than or equal to an anticipated upper use temperature (UUT), or (iii) from a LUT to an UUT, wherein LUT&#x2266;UUT, within which the substrate is intended to be used in the presence of water, and (b) depositing at least one polymer on at least a portion of the surface, said polymer being soluble in water to the extent that an aqueous solution of such polymer exhibits: (i) a lower critical solution temperature (LCST), wherein LCST&#x3c;LUT, or (ii) an upper critical solution temperature (UCST), wherein UUT&#x3c;UCST, or (iii) a LCST and a UCST, wherein UCST&#x3c;LCST and: (1) LCST&#x3c;LUT, or (2) UUT&#x3c;UCST.

Method for durable hydrophilization of a hydrophobic surface

The invention relates to a block copolymer and more especially to a thermoplastic elastomer block copolymer. The block copolymer is a diblock (block A)-(bloc B) copolymer, a triblock (block A)-(block B)-(block A), or a triblock (block A)-(block B)-(block C) copolymer, wherein block A is a stiff block, block B is a soft block, and block C is a stiff block. Block A or Block B comprises repetitive units deriving from segregation monomers.

Block copolymer

The invention relates to water-soluble block copolymers comprising at least one block of hydrophobic nature and at least one block of hydrophilic nature, the block of hydrophobic nature exhibiting hydrophilic units in an amount of between 33% and 99% by weight with respect to the total weight of the units of the hydrophobic block. These copolymers are preferably diblocks or triblocks and are prepared by a polymerization process referred to as a living or controlled. Control of their hydrophilic-lipophilic balance makes it possible to adjust their solubility in water and their self-association properties. These copolymers can be used in particular as adhesion agents or wetting agents.
