  • N-acyl sarcosinates as glyphosate adjuvants
    Patent number: 5985798
    Abstract: An adjuvant for glyphosate having increased activity, lower irritancy and lower toxicity than conventional adjuvants, and method of controlling weeds using the same. The adjuvant is C.sub.8 to C.sub.22 sarcosinate or sarcosinate salt, such as sodium cocoyl sarcosinate, sodium lauroyl sarcosinate, or combinations thereof, which is combined with glyphosate in low concentrations and provides effective activity.
    Type: Grant
    Filed: June 4, 1998
    Date of Patent: November 16, 1999
    Assignee: Hampshire Chemical Corp.
    Inventor: Joseph J. Crudden
  • Plant micronutrient chelating surfactant compounds
    Patent number: 5962717
    Abstract: Plant micronutrient compounds comprising N-acyl ED3A or salts thereof. The N-acyl ED3A derivatives chelate various trace metals, including iron, copper, zinc, manganese, cobalt and nickel.
    Type: Grant
    Filed: March 9, 1999
    Date of Patent: October 5, 1999
    Assignee: Hampshire Chemical Corp.
    Inventors: Arthur M. Nonomura, Barry A. Cullen, Joseph J. Crudden, John J. Nishio
  • N-acyl ethylenediaminetriacetic acid surfactants as enzyme compatible surfactants, stabilizers and activators
    Patent number: 5821215
    Abstract: Compositions including one or more enzymes and as the compatible chelating surfactant, salts of N-acyl ethylenediaminetriacetic acid ("ED3A"). Salts of N-acyl ED3A do not readily denature various enzymes, and thus are highly compatible with such enzymes, and enhance their detergent effectiveness to an unexpected degree.

  • Sarcosinates as fluazifop-butyl adjuvants and activators
    Patent number: 5686391
    Abstract: An adjuvant for Fluazifop-butyl, and preferably Fluazifop-P-butyl, having increased activity, lower irritancy and lower toxicity than conventional adjuvants. The adjuvant is C.sub.8 to C.sub.22 sarcosinate or sarcosinate salt, such as sodium cocoyl sarcosinate, sodium lauroyl sarcosinate, or combinations thereof, which is combined with Fluazifop-P-butyl and provides more effective activity.
    Type: Grant

  • Non-aqueous neutralization of N-acyl sarcosines
    Patent number: 5386043
    Abstract: A process for the non-aqueous neutralization of N-Acyl sarcosines. N-Acyl sarcosines are neutralized with anhydrous hydroxide or with hydroxide with low water content, ideally less than 20% water, using high shear. The process eliminates numerous stages previously required on route to a 100% active product. In addition, 30% solutions can be produced by the instant process, with the advantage of avoiding pH ranges at which gel phases or liquid crystals form.

  • Process for producing a synthetic detergent soap base from n-acyl sarcosine
    Patent number: 5328629
    Abstract: A method of producing a synthetic detergent soap base, comprising dissolving in an n-acyl sarcosine at an elevated temperature a fatty acid, and neutralizing the mixture with a base at a temperature sufficient to maintain fluidity to a pH of from about 4.5 to about 9.5. The resulting product is non-irritating and non-drying, and exhibits apparent skin substantivity and pleasant skin feel.
    Type: Grant
    Filed: June 26, 1992
    Date of Patent: July 12, 1994
    Assignee: Hampshire Chemical Corp.
    Inventor: Joseph J. Crudden
  • Process for producing a synthetic detergent soap base from n-acyl sarcosine
    Patent number: 5186855
    Abstract: A method of producing a synthetic detergent soap base, comprising neutralizing n-acyl sarcosine at an elevated temperature with a fatty acid salt to the desired pH, and allowing the mixture to cool. The resulting product is non-irritating and non-drying, and exhibits apparent skin substantivity and pleasant skin feel.
