Stearate Composition And Method Of Production Thereof
US Patent:
7456306, Nov 25, 2008
Filed:
Jul 28, 2004
Appl. No.:
10/558591
Inventors:
Steven M. Wolfgang - Glen Carbon IL, US
Todd P. Heider - St. Louis MO, US
Todd P. Heider - St. Louis MO, US
Assignee:
Mallinckrodt Inc - Hazelwood MO
International Classification:
C07C 51/43
US Classification:
554195
Abstract:
An improved alkali earth metal stearate composition is disclosed and is prepared by reacting a fatty acid component including at least about 80% by weight stearic acid and at least about 5% by weight palmitic acid with an alkali hydroxide to form an alkali soap. An aqueous metal salt solution is then added to the soap to form the improved alkali earth metal stearate. The improved alkali earth metal stearate includes a significant amount of the dihydrate form of the stearate.

US Patent:
2006028, Dec 14, 2006
Filed:
Jun 16, 2005
Appl. No.:
11/154849
Inventors:

Steven Wolfgang - Reston VA, US
Scot Randle - St. Louis MO, US
International Classification:
C07C 51/43
US Classification:
554195000
Abstract:
An improved alkaline earth metal stearate composition is disclosed and is prepared by reacting a fatty acid component including stearic acid and palmitic acid with an alkali hydroxide to form an alkaline soap. An aqueous metal salt solution is then added to the soap, and pH adjusted to less than about pH 8 to form the improved alkaline earth metal stearate. The improved alkaline earth metal stearate provides a substantially pure amount of the dihydrate form of the stearate.
