Abstract
Significantly expanding of current Egyptian market of detergent which forced the
producers to develop their products to adequately meet a wide new varieties of end-user
requests. Developing of powder and liquid laundry detergent depend mainly on
understanding the behaviors of main components of powder like surfactant, builder,
bleaching agents and enzymes. Evaluated the primary washing performance of
surfactants individually or binary with builders under optimum conditions using standard
artificially soiled fabrics which represent the common stains in Egyptian customer live.
Evaluate incrustation efficiency of some builders and its alternatives in powder and liquid
laundry detergent. Study the stability of enzymes in liquid and powder laundry detergent
compared to market products. Results indicate fatty alcohol C12-C18, 7 moles ethylene
oxide has the highest average total stains remover index among all types of selected
surfactants, and followed by sodium alkyllbenzene sulfonate C11-C13 then soap made
from 80% palm oil and 20% palm kernel oil. Fatty alcohol C10-C18, 5 moles ethylene
oxide has the lowest total stains remover index. Sodium tripolyphoshate improve washing
performance of alkyllbenzene sulfonate C11-C13 and fatty alcohol C12-C18, 7 moles
ethylene oxide and soap 80% palm oil/20%palm kernel. Sodium carbonate and sodium
silicate kept comparable washing performance with fewer amounts of alkyllbenzene
sulfonate C11-C13 and fatty alcohol C12-C18, 7 moles ethylene oxide. In case of soap 80%
palm oil/20%palm kernel they cannot compensate the reduction of its percentage. Our
prototype formulation with less amount of alkyllbenzene sulfonate C11-C13 and nonionic 7
EO or soap gave higher SRI value and lower foaming level than multinational products in
Egyptian market.
