Cleaning compositions and emulsions or microemulsions employing extended chain nonionic surfactants |
摘要 |
Synergistic combinations of extended chain surfactants and co-surfactants, emulsions or microemulsions and cleaning compositions incorporating the same are provided. In certain embodiments a surfactant system is disclosed which includes extended nonionic surfactants, and a linker surfactant. This system forms stable emulsions or microemulsions with oils, including non-trans fats and fatty acids and these emulsions or microemulsions are stable, irreversible and can be created at low temperature. The cleaning compositions may include the surfactant system alone, a stable emulsion or microemulsion with oil and the surfactant system, a pre-spotter or other pre-treatment or soft surface and hard surface cleaning compositions comprising the surfactant combination. |

1. A surfactant system for forming stable emulsions or microemulsions with oils comprising:
an extended chain nonionic surfactant having an intermediate polarity linking chain between a lipophilic segment and a hydrophilic segment of said surfactant, wherein said linking chain is selected from the group consisting of (PO)x, (EO)x, (PO)x(EO)x and combinations thereof, wherein x is from 1 to 16, wherein said extended surfactant comprises a compound of formula:
R-[L]x-[O—CH2—CH2]y where R is a linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radical having from about 8 to 20 carbon atoms, L is a linking group, x is the chain length of the linking group ranging from 5-15, and y is the average degree of ethoxylation ranging from 1 to 5; a linker co-surfactant selected from the group consisting of monoglycerides, diglycerides, fatty acids, fatty diacids and combinations thereof wherein said link co-surfactant has a small hydrophilic head and/or surfactants with twin or bulky hydrophobic tail(s); wherein the system is capable of forming a stable emulsion or microemulsion with oils. |
