Patent number: 5609855Abstract: Antiperspirant compositions in the form of gel sticks, which provide the user with excellent antiperspirant efficacy while exhibiting good stability, are disclosed. These compositions utilize particular gelling agents which are stable under the acidic conditions required in antiperspirant compositions. Specifically, the compositions have an acidic pH and include an antiperspirant active, a gelling agent which comprises dibenzylidene alditols substituted on the benzene ring with an electron withdrawing group, and a solvent for the gelling agent. Examples of preferred gelling agents include di(meta-fluorobenzylidene) sorbitol and di(meta-chlorobenzylidene) sorbitol. The method of preventing and controlling perspiration wetness using these compositions is also disclosed.Type: GrantFiled: October 18, 1995Date of Patent: March 11, 1997Assignee: The Procter & Gamble CompanyInventors: Young S.

Patent number: 5334764Abstract: Amines such as methyl amine are reacted with materials such as reducing sugars in hydroxy solvents such as methanol to prepare N-alkyl polyhydroxy amines. Accordingly, glucose is reacted with methyl amine and the resulting adduct is hydrogenated to yield N-methylglucamine. The N-alkyl polyhydroxyamines can be subsequently reacted with fatty esters to provide polyhydroxy fatty acid amides useful as detersive surfactants. Thus, detersive surfactants are available from non-petrochemical precursors such as sugars and sugar sources such as corn syrup, and fatty acid esters derivable from various fats and oils.Type: GrantFiled: May 6, 1993Date of Patent: August 2, 1994Assignee: The Procter & Gamble CompanyInventors: Jeffrey J. Scheibel, Daniel S. Connor, Robert E. Shumate, James B. St. Laurent

Patent number: 5298636Abstract: Polyhydroxy amines reacted with fatty acid esters yield polyhydroxy fatty acid amide surfactants, such as the C.sub.11 -C.sub.17 fatty N-methyl glucamides, which may be contaminated with secondary amines. Such amines are acylated by a reaction with acetic anhydride. The resulting "clean" polyhydroxy fatty acid amide surfactants are preferred for use in the presence of oxidants, especially in the formulation of modern, colorless liquid detergents.Type: GrantFiled: September 23, 1992Date of Patent: March 29, 1994Assignee: The Procter & Gamble CompanyInventors: Daniel S.

Patent number: 5298634Abstract: Near-quantitative conversion of maleate to D,L-malate is rapidly secured by heating an aqueous alkaline mixture of maleate and excess of the divalent cations calcium, magnesium or mixtures thereof in a reactor at autogenous pressures and at temperatures above reflux. The simplest raw materials for the process are maleic anhydride and calcium hydroxide. The product is secured as an unusual, typically granular solid form of the divalent metal malate salt which is very useful in processes for preparing other malate salts, malic acid, or 2,2'-oxodisuccinate laundry detergent builders.Type: GrantFiled: December 10, 1987Date of Patent: March 29, 1994Assignee: The Procter & Gamble CompanyInventors: Daniel S.

Patent number: 5188769Abstract: The synthesis of polyhydroxy fatty acid amide surfactants exemplified by the compound C.sub.11 H.sub.23 C(O)N(CH.sub.3)CH.sub.2 [CHOH].sub.4 CH.sub.2 OH by reacting a fatty acid ester with an N-alkyl sugar amine can result in contamination of the product surfactant by residual sources of fatty acids. These residual fatty acids may be unacceptable in high sudsing detergent compositions, such as dishwashing liquids, especially with Ca or Mg cations. The process of this invention reacts such contaminants with alkyl amines or, especially, ethanolamine, to convert them into fatty alkyl- or alkanolamides, which are quite acceptable in fully-formulated detergent compositions for home or industrial use.Type: GrantFiled: March 26, 1992Date of Patent: February 23, 1993Assignee: The Procter & Gamble CompanyInventors: Daniel S. Connor, Jeffrey J. Scheibel, Bruce P. Murch, Mark H. Mao, Eugene P. Gosselink, Roland G. Severson, Jr.

Patent number: 4798907Abstract: High yields of 2,2'-oxodisuccinate are secured by reacting maleate and malate in aqueous alkaline media containing mixtures of particular divalent (e.g., Ca.sup.2+) and solubilizing monovalent (e.g., Na.sup.+) cations. In a preferred embodiment, the process has both an elevated temperature primary reaction step and one or more low temperature maturation steps. Yields of 2,2'-oxodisuccinate are increased and formation of fumarate byproduct is minimized.Type: GrantFiled: February 26, 1988Date of Patent: January 17, 1989Assignee: The Procter & Gamble CompanyInventors: Clifford L. MacBrair, Jr., Daniel S. Connor, Herbert C. Kretschmar, James A. Cleary
