Regulatory Information
Chemical: Octadecanoic acid, magnesium salt
Octadecanoic acid, magnesium salt (2:1) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Octadecanoic acid, magnesium salt (2:1) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)
Octadecanoic acid, magnesium salt: Does not have an individual approval but may be used under an appropriate group standard
Other Safety InformationIMAP assessments - Octadecanoic acid, magnesium salt: Human health tier I assessment
Fire HazardsCombustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.
Hazards Summary
This TLV Documentation applies only to stearic acid and magnesium, sodium, and zinc stearates. It excludes stearates of other metals. TLV Basis is lower respiratory tract irritation. No acute systemic effects of stearic acid have been reported after ingestion. . . . Sprague-Dawley rats fed stearic acid in their diet at 3000 ppm for 209 days showed 'severe pulmonary infection consisting of tracheobronchitis, lobular pneumonia, lipoid histiocytic response, and abscess formation.' [ACGIH] See Stearic acid.
Chemie und Industrie
Verwendung und Herstellung
Uses
CIR ingredient: Magnesium Stearate
Used in cosmetics, pharmaceuticals, food additives, waterproofing agents, plastic stabilizers, emulsifiers, and rubber lubricants and dusting agents; Stearic acid occurs naturally in human and animal fats and oils and in some vegetable oils, including cocoa oil. Stearic acid can be prepared from animal fat (triglyceride) by treating with water at high temperature, leading to hydrolysis of triglycerides, or by hydrogenation of unsaturated vegetable oils such as cottonseed oil. [ACGIH]
Used in baby dusting powders; as lubricant for plastics; as emulsifying agent in cosmetics; as drier in paints and varnishes; as flatting agent; as anticaking agent in foods and fire extinguishers; and as lubricant in making pharmaceutical tablets; [HSDB]
Painting (Pigments, Binders, and Biocides) [Category: Paint]
IN BABY DUSTING POWDERS
Dusting powder, lubricant for plastics, emulsifying agent in cosmetics, drier in paints and varnishes and flatting agent.
Impuritiescontains small amounts of the oleate and 7% magnesium oxide. /technical grade/
