Lubricant and surface conditioner for formed metal surfaces

A liquid concentrate suitable for mixing with water to produce a liquid lubricant and surface conditioner forming composition, said concentrate comprising water and:

• (A) an amount of a component selected from the group consisting of molecules of oxa acids and their methyl esters and mixtures thereof corresponding to general formula (I):
• H3C—(CH2)n—CH═CH—(CH2)m—O—(CH2CH2O)x—CH2—C(═O)—OR (I)
• where each of m, n and x, which may be the same or different, is a positive integer, x is not less than 2, and R represents H or CH3;
• and
• (B) an amount of a component selected from the group consisting of:
• (B.1) molecules conforming to general formula (II):
• R1O(CH2CH2O)y(CH2CHCH3O)zH (II),
• where R1 is a moiety selected from the group consisting of (i) saturated and unsaturated straight and branched chain aliphatic monovalent hydrocarbon moieties and (ii) saturated and unsaturated straight and branched chain aliphatic monovalent hydrocarbon moiety substituent bearing phenyl moieties in which the aromatic ring in the phenyl moiety is directly bonded to the oxygen atom appearing immediately after the R1 symbol in formula (II);
• y is a positive integer, and z is zero to 20;
• (B.2) molecules conforming to general formula (III):
• R2C(O)O(CH2CH2O)pH (III)
• where R2 is selected from the group consisting of saturated and unsaturated straight and branched chain aliphatic monovalent hydrocarbon moieties and p is a positive integer;
• (B.3) molecules conforming to general formula (IV):
• HO(CH2CH2O)q(CH2CHCH3O)r(CH2CH2O)q′H (IV),
• where each of q and q′, which may be the same or different, represents a positive integer from 2 to 10 and r represents a positive integer from 3 to 60;
• (B.4) molecules conforming to general formula (V):
• HO(CH2CHCH3O)s(CH2CH2O)t(CH2CHCH3O)s′H (V)
• where each of s and s′, which may be the same or different, represents a positive integer from 10 to 63 and t represents a positive integer from 2 to 20;
• and mixtures thereof;
• wherein the amount of component (B) has a ratio to the amount of component (A) that is from about 5.0:1.0 to about 20:1.0.
