Abstract:
A method for manually cleaning an object comprising the step of manually washing said object in and contacting a user's hands with a washing solution comprising water and a detergent composition comprising a polymeric suds stabilizer and a diamine, wherein said diamine has a molecular weight of less than or equal to 400 g/mol; and said suds stabilizer is selected from the group consisting of:(a) polymers comprising at least one monomeric unit of the formula: â€ƒwherein each of R1, R2 and R3 are independently selected from the group consisting of hydrogen, C1 to C6 alkyl, and mixtures thereof; L is selected from the group consisting of O, NR6, SR7R8 and mixtures thereof, wherein R6 is selected from the group consisting of hydrogen, C1 to C8 alkyl and mixtures thereof; each of R7 and R8 are independently hydrogen, O, C1 to C8 alkyl and mixtures thereof, or SR7R8 form a heterocyclic ring containing from 4 to 7 carbon atoms, optionally containing additional hetero atoms and optionally substituted; Z is selected from the group consisting of: â€”(CH2)â€”, (CH2â€”CH&boxH;CH)â€”, â€”(CH2â€”CHOH)â€”, (CH2â€”CHNR6)â€”, â€”(CH2â€”CHR14â€”O)â€” and mixtures thereof; wherein R14 is selected from the group consisting of hydrogen, C1 to C6 alkyl and mixtures thereof; z is an integer selected from about 0 to about 12; A is NR6R5, wherein each of R4 and R5 are independently selected from the group consisting of hydrogen, C1 to C8 alkyl, and mixtures thereof, or NR4R5 form an heterocyclic ring containing from 4 to 7 carbon atoms, optionally containing additional hetero atoms, optionally fused to a benzene ring, and optionally substituted by C1 to C8 hydrocarbyl; and wherein said polymeric suds stabilizer has a molecular weight of from about 1,000 to about 2,000,000 daltons; (b) a proteinaceous suds stabilizer, said proteinaceous suds stabilizer having an isoelectric point of from about 7.5 to about 11.5 (c) a zwitterionic polymeric suds stabilizer; and (d) mixtured thereof; wherein said suds stabilizer is mild, suds enhancing and suds stabilizing such that suds produced by said solution is maintained for an extended period of time by said suds stabilizer and a user's hands, after submersion in a solution containing said suds stabilizer, are not irritated.
