Surfactant systems, using microfibrous cellulose to suspend particulates therein, are described. Methods of making these systems are also described.

Well treatment is disclosed that includes injecting a well treatment fluid with insoluble polyol polymer such as polyvinyl alcohol (PVOH) dispersed therein, depositing the insoluble polymer in the wellbore or an adjacent formation, and thereafter dissolving the polymer by reducing salinity and / or increasing temperature conditions in the environment of the polymer deposit. The method is disclosed for filter cake formation, fluid loss control, drilling, hydraulic fracturing and fiber assisted transport, where removal of the polyol at the end of treatment or after treatment is desired. The method is also disclosed for providing dissolved polyol as a delayed breaker in crosslinked polymer viscosified systems and viscoelastic surfactant systems. Also disclosed are well treatment fluids containing insoluble amorphous or at least partially crystalline polyol, and a PVOH fiber composition wherein the fibers are stabilized from dissolution by salinity.

Systems and methods are described for a chemical reaction synthesis of films, coatings or layers using surfactants. A method includes providing a surfactant as an impurity within at least one of a first precursor layer that is coupled to a first substrate and a second precursor layer that is coupled to a second substrate; forming a composition layer; and moving the first substrate relative to the second substrate, wherein the composition layer remains coupled to the second substrate. The first precursor layer includes a first chemical reactant, the second precursor layer includes a second chemical reactant, and the composition layer includes a chemical product yielded by a chemical reaction between the first chemical reactant and the second chemical reactant.

A soft, flexible, low-density, open-cell, thermoplastic, absorbent foam formed from a foam polymer formula including a balanced amount of a plasticizing agent and a surfactant in combination with a base resin. Thermoplastic elastomers can be added to the foam polymer formula to improve softness, flexibility, elasticity, and resiliency of the resulting foam. The surfactant may be either a single surfactant or a multi-surfactant system. The foam possesses a number of qualities, such as softness and strength, which render the foam particularly suitable for use in a variety of personal care products, medical products, and the like.

Mild shampoo compositions are described that are economical, have excellent in-use properties, and provide enhanced conditioning benefits. The compositions have low ocular irritation potential and are particularly suitable for use by children. The compositions include a surfactant system composed on an alkyl ethoxy sulfate having at least 3 ethylene oxide groups, a betaine surfactant, and an hydroxysultaine surfactant in specific ratios; and a non-volatile water-insoluble silicone. In-vitro tests are described that allows selection of optional ingredients that do not compromise the mildness or hair conditioning performance of the composition.

The blend of dibasic esters comprises two or more of dialkyl methylglutarate, dialkyl adipate, dialkyl ethylsuccinate, dialkyl succinate, dialkyl glutarate.

A structured liquid detergent composition in the form of a liquid matrix made up of an external structuring system of a bacterial cellulose network; water; and surfactant system including an anionic surfactant; a nonionic surfactant; a cationic surfactant; an ampholytic surfactant; a zwitterionic surfactant; or mixtures thereof, wherein said liquid matrix has a yield stress of from about 0.003 Pa to about 5.0 Pa at about 25° C. and provides suitable particle suspension capabilities and shear thinning characteristics.

A drilling fluid, comprising an aqueous continuous phase, and a surfactant system comprising a mixture of an ester phosphate and a non-ionic ethoxylated alcohol. The drilling fluid may also contain one or more of at least one salt, an alkaline material, a viscosifying agent, a starch or starch derivative, a bridging agent, a weighting material, and a diesel oil or non-aromatic oil.

We claim a fragrance delivery system consisting of a mixture of various polymers oligomers and stabilizers capable of forming a surfactant complex gel dispersion when combined with a cleansing surfactant base and yielding high levels of fragrance deposition onto the skin, hair or other surface such as a textile, from a cleansing or softening consumer product comprising a micelle forming surfactant. The internal phase or dispersible phase of this surfactant complex gel dispersion (GLPPD) is made of a mixture of various immiscible polymers, oligomers and stabilizers forming a complex gel with the surfactant platform and whose ratio and composition are selected to dissolve preferentially a wide range of fragrance raw materials. The selection criteria are, first, that the fragrance should present a higher fragrance partitioning ratio into the surfactant complex gel phase than into the free micelles of the surfactant, second, that the surfactant complex gel should not be further solubilized by the free micelles, and third, that the polymer mixture selected should complex with the surfactant system. The external or dispersing phase of the GLPPD is made of a single cationic polymer or a mixture of cationic polymers that have been hydrated and associated with the surfactant to form a complex gel structure that cannot be further solubilized by the free micelles.
