Abstract: Condensation products (esters or amides) are prepared from an alkylolamine and an aliphatic acid having a carbon chain of at least 8 carbon atoms.  Alkylolamines specified are triethanolamine, diethanolamine, tri-isopropanolamine and 2 - amino - 2 - methyl - 1 - propanol.  The aliphatic acid may be lauric acid or a mixture of acids such as those obtained from coconut oil.  In an example, diethanol-amino-ethyl laurate is prepared by steam-heating a mixture of coconut oil fatty acids and triethanolamine to 160-165 DEG  C. until the viscosity of the reaction product is 320-340 s.v.s. at 100 DEG  F., and then cooling the mixture.  Partial esters of phosphoric acid are prepared by reacting an aliphatic alcohol having a carbon chain of at least 8 carbon atoms with phosphorus pentoxide.  The aliphatic alcohol may be lauryl, n-octyl, n-nonyl or n-undecyl alcohol or decanol.  In an example primary n-decyl phosphate is prepared by mixing n-decanol and phosphorus pentoxide in a reaction vessel and maintaining the mixture at about 110 DEG  C. for 3 hours while it is continuously circulated by withdrawing the mixture at the base of the vessel and re-introducing it at the top.ALSO:A lubricating and conditioning anti-static composition for textile fibres comprises mineral lubricating-oil and (A) a partial ester of phosphoric acid with a long-chain aliphatic alcohol, (B) a condensation product formed from an alkylolamine and a long-chain aliphatic acid with loss of water, (C) an alkylolamine, and (D) an alkyl phenol.  The composition is free from sulphonated and/or sulphated compounds.  By "long-chain" is meant a chain of at least 8 carbon atoms.  The partial ester (A) may be formed from lauryl alcohol, n-octyl alcohol, n-nonyl alcohol, decanol, or n-undecyl alcohol.  The product (B) may be prepared by condensation of an alkylolamine such as triethanolamine, diethanolamine, tri-isopropanolamine or 2-amino-2-methyl-1-propanol, with lauric acid or a mixture of acids such as those from coconut oil; the alkylolamine (C) may be any of those specified in forming this product.  The alkyl phenol (D) may be 2,4-ditertiaryamyl-phenol, 2,4,6-tritertiary-amyl-phenol, or 3-methyl-4,6-ditertiary-butyl-phenol.  The composition may be applied to filaments of cellulose esters such as the acetate, propionate, butyrate, acetate-propionate and acetate-butyrate and to cellulose ethers such as ethyl cellulose and benzyl cellulose. In an example, a composition is formed of 60 parts by weight of white mineral oil, 9 parts of primary n-decyl phosphate, 20 parts of diethanolaminoethyl laurate and 2.5 parts each of triethanolamine and 2,4-ditertiaryamyl-phenol.ALSO:A lubricating composition for textile fibres comprises mineral lubricating oil and (A) a partial ester of phosphoric acid with a long-chain aliphatic alcohol, (B) a condensation product formed from an alkylolamine and a long-chain aliphatic acid with loss of water, (C) an alkylolamine and (D) an alkyl phenol.  The composition is free from sulphonated and/or sulphated compounds. By "long-chain" is meant a chain of at least 8 carbon atoms. The partial ester (A) may be formed from lauryl alcohol, n-octyl alcohol, n-nonyl alcohol, decanol, or n-undecyl alcohol.  The product (B) may be prepared by condensation of an alkylolamine such as triethanolamine, diethanolamine, tri-isopropanolamine or 2-amino-2-methyl-1-propanol, with lauric acid or a mixture of acids such as those from coconut oil; the alkylolamine (C) may be any of those specified in forming this product.  The alkyl phenol (D) may be 2, 4-ditertiary-amyl-phenol, 2, 4, 6-tritertiary-amyl-phenol, or 3-methyl-4, 6-ditertiary-butyl-phenol.  In an example, a composition is formed of 60 parts by weight of white mineral oil, 9 parts of primary n-decyl phosphate, 20 parts of diethanolaminoethyl laurate and 2.5 parts each of triethanolamine and 2, 4-ditertiarymyl phenol.
