Product Overview

Applications

Documented applications: Uses: CIR ingredient: Stearic Acid, Used in cosmetics, pharmaceuticals, 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], Present as a glyceride in animal fats and oils and in some vegetable oils, [Merck Index] Used as intermediate for metallic soaps and greases, household soap products, synthetic rubber vulcanization activators, and alkyd and epoxy resins for surface coatings, Also used in cosmetic and pharmaceutical creams and lotions, candles, phonograph records, dental materials, insulators, lubricants, shoe and metal polishes, coatings, food packaging, and modeling compounds, Also used as a synthetic rubber polymerization emulsifier, a release agent in baked goods and confectioneries, a dispersing agent and softener in rubber compounds, a paper sizing ingredient (specialty papers), a textile auxiliary, to make metal stearates (aluminum, zinc, etc.), for impregnating plaster of Paris, to aid incorporation and dispersion of zinc oxide in rubber and paint, and to cure polybutadiene, [HSDB] Stearic acid occurs naturally in human and animal fats and oils and in some vegetable oils, Pulp and Paper Processing [Category: Industry], Textiles (Fiber & Fabric Manufacturing) [Category: Industry], Painting (Pigments, Binders, and Biocides) [Category: Paint], Plastic Composites Manufacturing [Category: Industry], For stearic acid (USEPA, OPP Pesticide Code: 079082) there are 0 labels match., SRP: Not registered for current use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses., Reported uses (ppm):, Table: Reported uses (ppm): (Flavor and Extract Manufacturers' Association) [Table#3750], For suppositories, coating enteric pills, ointments and for coating bitter remedies. Manufacturing stearates of aluminum, and other metals, stearin soap for opodeldoc, modeling compounds, impregnating plaster of Paris, in vanishing creams and other cosmetics., In preparation of sodium stearate, which is the solidifying agent for the official glycerin suppositories, in enteric tablet coating, ointments, and for many other commercial products, such as toilet creams, vanishing creams, solidified alcohol, etc., (when labeled solely for external use, it is exempt from the requirement that it be prepared from edible fats and oils)., For more Uses (Complete) data for Stearic acid (8 total), please visit the HSDB record page., Plastics -> Typical concentration range in plastic materials -> 1%, Use (kg, approx.) in Germany (2009): >10, Consumption (g per capita, approx.) in Germany (2009): 0.000122, Calculated removal (%): 100, This is an endogenously produced metabolite found in the human body. It is used in metabolic reactions, catabolic reactions or waste generation., Use Classification: EPA Safer Chemical Functional Use Classes -> Surfactants, Safer Chemical Classes -> Green circle - The chemical has been verified to be of low concern, Fragrance Ingredients, Flavouring Agent -> FLAVOURING_AGENT -> JECFA Functional Classes, Flavoring Agents -> JECFA Flavorings Index, Plastics -> Polymer Type -> Polyolefin-I, Polyolefin-II, Cosmetics -> Refatting, Emulsion stabilizing, Emulsifying, Cleansing, Plastics -> Other functions -> Plasticiser, lubricant, Industry Uses: Cleaning agent, Filler, Not Known or Reasonably Ascertainable, Soil amendments (fertilizers), Emulsifier, Intermediate, Anti-static agent, Adhesion, cohesion promoter, Softener and conditioner, Defoamer, Anti-adhesive, cohesive, Polymerization promoter, Foamant, Lubricating agent, Binder, Other, Sizing agent, Surfactant (surface active agent), Processing aids not otherwise specified, Opacifer, Consumer Uses: Processing aids not otherwise specified, Surface modifier, Thickening agent, Viscosity modifiers, Cleaning agent, Household Products: Information on 616 consumer products that contain Stearic acid in the following categories is provided:, • Auto Products, • Commercial, Institutional, • Home Maintenance, • Inside the Home, • Personal Care, • Pesticides, Methods of Manufacturing: Commercially it is produced by the hydrogenation of the unsaturated 18-carbon fatty acids of soybean, cottonseed or other vegetable oils. When obtained from animal fats by hydrolysis and fractional crystallization, commercial stearic acid is a mixture of solid organic acids, chiefly palmitic and stearic acids. Commercial products containing about 90% stearic acid are produced by hydrolysis and crystallization of a completely hydrogenated vegetable oil or by fractional distillation of fatty acid mixtures obtained from tallow., It is produced commercially from hydrolyzed tallow derived from edible sources or from hydrolyzed, completely hydrogenated vegetable oil derived from edible sources., From high-grade tallows and yellow grease stearin by washing, hydrolysis with the Twitchell or similar reagent, boiling, distilling, cooling, and pressing, from oleic acid by hydrogenation., Formulations, Preparations:, There are, three types of.
