The present invention relates to microemulsions and methods of preparing and using the microemulsions.

The present disclosure provides a surfactant blend containing (i) an extended chain anionic surfactant and (ii) an extended chain intermediate surfactant. The surfactant blend may be used in the preparation of cleaning compositions, or compositions for use in oil field treatment applications, water based metal working applications and polyurethane foam applications.

A cleaning composition is particularly suited for cleaning dirty intake valves. The cleaning composition includes a high solvency surfactant/solvent which has a Kb greater than 100 or polar Hansen solubility parameter greater than 6. The surfactant/solvent is combined with a carrier such as water or an organic carrier and a surfactant. A wetting agent may also be employed. The cleaning composition is added to the intake air as a mist as the engine is running. Aqueous and non-aqueous versions are disclosed.

The present disclosure is directed to compositions including a microemulsion comprising lecithin, a polysorbate, an alkyl polyglycoside, and optionally a solvent. Uses of the microemulsions are also disclosed.

The invention discloses synergistic combinations of surfactant blends and cleaning compositions employing the same. In certain embodiments a surfactant system is disclosed which includes an extended anionic surfactant with novel linker surfactants including one or more of an alkyl glycerol ether, an ethoxylated alkyl glycerol ether, an alcohol ethoxylate and/or a Gemini surfactant. This system forms emulsions with, and can remove greasy and oily stains, even those comprised of non-trans fats. The compositions may be used alone, as a pre-spotter or other pre-treatment or as a part of a soft surface or hard surface cleaning composition.

The present invention relates to amino silicone nanoemulsions. More specifically, the present invention relates to amino silicone nanoemulsions that may be used to protect surfaces from being soiled or wetted.

Compositions are disclosed that include PEG-modified triglycerides as a surfactant. The mixtures form stable microemulsions with oils and fatty acids which can be the resultant product, such as lubricants, sunscreens, or triglyceride-based products. These emulsions or microemulsions are stable, irreversible, and can be created at low temperature. These can be used in detergents, rinse aids and the like to form microemulsions to remove oils and greasy soils, such as non-trans fats and fatty acids from substrates/surfaces often without the need for linker or other cosurfactants. Methods of making the compositions/microemulsions are included as well as uses thereof.

Disclosed is a stable micro-emulsion comprising: water; a water soluble, hydroxy-containing polymeric material; (c) at least one a hydrotrop; and (d) a propellant comprising trans-1,3,3,3-tetrafluoropropene

The invention relates to a composition, comprising: (A) water; (B) one or more liquid olefinic unsaturated compounds having at least 8 carbon atoms in the backbone having a water solubility of less than 2 g in 1,000 g of water at 25 C., respectively; (C) optionally one or more liquid esters having a water solubility of less than 2 g in 1,000 g of water at 25 C.; (D) one or more amphiphilic liquid compounds; (E) one or more of an anionic (E1), a cationic (E2), a non-ionic (E3) and optionally an amphoteric tenside (E4); (F) optionally one or more additives.
