SYNERGISTIC COMBINATION OF POLYSACCHARIDE-BASED SURFACTANTS AND BIO-BASED SURFACTANTS
Surfactant blends are disclosed which exhibit improved stability over a wide pH range. The surfactant blends include a polysaccharide-based surfactant and a bio-based surfactant. Methods of making and using the surfactant blends are further provided.
1 . A surfactant blend composition comprising:
a dextran-based polysaccharide surfactant or dextrin-based polysaccharide surfactant; and
a bio-based surfactant comprising one or more of an alkylpolyglucoside based surfactant, a rhamnolipid surfactant, and a sophorolipid surfactant.
2 . The surfactant blend composition of claim 1 , wherein the dextrin-based polysaccharide surfactant comprises a maltodextrin.
3 . The surfactant blend composition of claim 2 , wherein the maltodextrin has a dextrose equivalent value of about 3 to about 25.
4 . The surfactant blend composition of claim 2 , wherein the maltodextrin has a dextrose equivalent value of about 4.5 to about 7.0.
5 . The surfactant blend composition of claim 2 , wherein the maltodextrin has a dextrose equivalent value of about 9.0 to about 12.0.
6 . The surfactant blend composition of claim 1 , wherein at least a portion of the dextran-based polysaccharide surfactant or the dextrin-based polysaccharide surfactant is formed as a reaction product of a polysaccharide and a fatty acid or fatty acid salt.
7 . The surfactant blend of claim 6 , wherein the fatty acid or fatty acid salt comprises a C4-C20 fatty acid or C4-C20 fatty acid salt.
8 . The surfactant blend composition of claim 1 , wherein the bio-based surfactant comprises an alkylpolyglucoside based surfactant.
9 . The surfactant blend composition of claim 1 , wherein the bio-based surfactant comprises a rhamnolipid surfactant.
10 . The surfactant blend composition of claim 1 , wherein the bio-based surfactant comprises a sophorolipid surfactant.
11 . The surfactant blend composition of claim 1 further comprises one or more additional surfactants and hydrotropes.
12 . The surfactant blend composition of claim 11 , wherein the additional surfactants comprise polysaccharide, nonionic, anionic, zwitterionic, amphoteric, or cationic surfactants.
13 . The surfactant blend composition of claim 12 , wherein the anionic surfactant comprises a sulfonic acid-based surfactant.
14 . The surfactant blend composition of claim 13 , wherein the sulfonic acid-based surfactant comprises an alkylbenzene sulfonic acid salt, a sulfate, a phosphate, or a carboxylate.
15 . The surfactant blend composition of claim 12 , wherein the cationic surfactant comprises a quaternary ammonium salt, a betaine, or a sultane.
16 . The surfactant blend composition of claim 12 , wherein the nonionic surfactant comprises an ethoxylate, a polysaccharide, or an alcohol.
17 . The surfactant blend composition of claim 12 , wherein the zwitterionic, amphoteric surfactant comprises a phospholipid, an amidobetaine, a lauryldimethylamine N-oxide, or a lecithin.
18 . The surfactant blend composition of claim 11 , wherein the hydrotropes comprise sodium xylene sulfonates, betaines and hydroxy sultaines/sulfonates proprionates, diproprionates, organic acids, alkanoates, phosphate esters and functionalized alkylpolyglucosides.
19 . A personal care product, a household cleaning product, a laundry care product, or an oilfield production surfactant product comprising the surfactant blend composition of claim 1 .
