Summary: | Surface active agents or surfactants are important class of compound in laundry detergent
and fabric softeners as they are the key ingredient that determines the performance of the
products. Anionic surfactants for laundry detergent and cationic surfactants for fabric
softener both perform independently, can be derived from renewable vegetable based
feedstock, namely, and saturated palm stearin fatty acid or methyl ester which provide
equivalent carbon chain length as that of tallow based feedstock. Methyl ester sulphonate
(MES), an anionic surfactant, has been prepared by a sulphonation process between palm
stearin methyl ester and sulfur trioxide followed by bleaching and neutralization processes
while quartenized triethanolamine ester or esterquats, a cationic surfactant, has been
prepared either by the condensation reaction between fatty acid and triethanolamine or
interesterification reaction between methyl ester and triethanolamine. The cationic
property was provided on triethanolamine ester through a quaternization reaction by
dimethyl sulfate. As a household fabric care products, these two surfactants meet the
biodegradability criteria as they are being discharged into the sewarage systems. The two
surfactants, when formulated into laundry detergent and fabric softeners, respectively, are
branded under the 'PALM TOUCH' product series. |
