Abstract:
1. An aqueous based solvent free degreaser composition comprising a nonionic surfactant component, wherein said nonionic surfactant component consists of two nonionic surfactants selected from the group consisting of: (1) 0.15%–5% of an alcohol alkoxylate with a fatty alcohol moiety having the Formula: wherein R is a C 8 to C 18 branched or straight chain alkyl group, m is within the range of about 0 to 14, n is within the range of about 0 to 14, o is within the range of about 0 to 14, p is within the range of about 0 to 14, and R′ is —CH 3 , —CH 2 CH 3 , and mixtures thereof, R″ is —CH 3 , —CH 2 CH 3 , and mixtures thereof, and R′″ is —OH, —CH 3 , —O—C 3 –C 18 hydroxyalkyl group and mixtures thereof; or (2) 0.15%–5% of a fatty alcohol moiety having the Formula: wherein R is a C 8 to C 18 branched or straight chain alkyl group, x is within the range of about 0 to 14; y is within the range of about 3 to 14; z is within the range of about 0 to 20; R′ is —CH 3 , —CH 2 CH 3 , and mixtures thereof, R″ is —CH 3 , —CH 2 CH 3 , and mixtures thereof, and R′″ is —CH, —CH 3 , —O—C 3 –C 18 hydroxyalkyl group and mixtures thereof; or (3) 0.15%–5% of a fatty alcohol having oxyethylate moieties having the Formula: wherein R=C 10 –C 13 branched or straight chain alkyl group and x is within the range of about 4 to 10; or (4) 0.15%–5% of a nonionic surfactant characterized as a block or heteric/block polyoxyalkylene having a cloud point in a 1 weight percent aqueous solution of about 15° C. to about 25° C. having the Formula I: wherein, Y represents the nucleus of an active hydrogen-containing organic compound having a functionality of x and (1) about 2 to about 6 carbon atoms and 2 to 3 reactive hydrogen atoms or (2) about 6 to about 18 carbon atoms and 1 to 3 reactive hydrogen atoms; A represents a lower alkylene oxide selected from the group consisting of propylene oxide, butylene oxide, tetrahydrofuran or mixtures thereof wherein up to 25 percent by weight of A is reacted directly with said organic compound in admixture with ethylene oxide in Formula I and 75 percent by weight or more of A is subsequently reacted to produce said polymer; o is within the range of about 0 to 26, m is within the range of about 0 to 110, and n is within the range of about 0 to 26, wherein further, the molecular weight range is from about 1,000 to 20,000, or (5) 0.15%–5% of a nonionic surfactant characterized as a block or heteric/block polyoxyalkylene having a cloud point in a 1 weight percent aqueous solution of about 15° C. to about 25° C. having the Formula II: wherein, Y represents the nucleus of an active hydrogen-containing organic compound having a functionality of x and (1) about 2 to about 6 carbon atoms and 2 to 3 reactive hydrogen atoms or (2) about 6 to about 18 carbon atoms and 1 to 3 reactive hydrogen atoms; A represents a lower alkylene oxide selected from the group consisting of propylene oxide, butylene oxide, tetrahydrofuran or mixtures thereof wherein up to 25 percent by weight of A is reacted directly with said organic compound alone in Formula II and 75 percent by weight or more of A is subsequently reacted to produce said polymer; o is within the range of about 0 to 26, m is within the range of about 0 to 110, and n is within the range of about 0 to 26, wherein further, the molecular weight range is from about 1,000 to 20,000, or (6) 0.15%–5% of a nonionic surfactant characterized as a block or heteric/block polyoxyalkylene having a cloud point in a 1 weight percent aqueous solution of about 15° C. to about 25° C. having the Formula III: wherein, Y represents the nucleus of an active hydrogen-containing organic compound having a functionality of x and (1) about 2 to about 6 carbon atoms and 2 to 3 reactive hydrogen atoms or (2) about 6 to about 18 carbon atoms and 1 to 3 reactive hydrogen atoms; A represents a lower alkylene oxide selected from the group consisting of propylene oxide, butylene oxide, tetrahydrofuran or mixtures thereof wherein up to 25 percent by weight of A is reacted directly with said organic compound alone in Formula and III and 75 percent by weight or more of A is subsequently reacted to produce said polymer; o is within the range of about 0 to 26, m is within the range of about 0 to 110, and n is within the range of about 0 to 26, wherein further, the molecular weight range is from about 1,000 to 20,000, or (7) 0.15%–5% of an alkyl phenol alkoxylate having the Formula: wherein P is phenyl group, R is a C 8 or C 9 branched or straight chain alkyl group, m is within the range of about 3 to 12, and n is within the range of about 0 to 12.
