Here is a detailed description of glycerol ether oleate, including its usage characteristics, regulatory parameters, and quality standards:
Glycerol Ether Oleate
1. Usage Characteristics
Glycerol ether oleate is primarily used in the preparation of leveling agents and detergents. Its specific applications include:
- Preparation of Wool Leveling Agents: By combining glycerol ether oleate with other components like tartaric acid, fatty amine polyoxyethylene ether, and ethylene glycol fatty acid ester, a wool leveling agent can be formulated. This agent enables softer dyeing on wool, with reduced fading after dyeing.
- Preparation of High-Efficiency Detergents: Glycerol ether oleate, along with fatty amide, ethylene oxide, coconut fatty acid, pentaerythritol, and oleic acid diethanolamide, can be used to create a detergent with excellent emulsifying, cleaning, antistatic, and degreasing properties. It is suitable for surface degreasing in the metal processing industry and can inhibit rusting of steel.
- Preparation of High-Temperature Leveling Agents: By incorporating glycerol ether oleate with tartaric acid, glacial acetic acid, and other components, a high-temperature leveling agent can be formulated. This agent exhibits excellent dye dispersion and initial dye retardation properties, making it suitable for high-temperature and high-pressure dispersion leveling of polyester fibers.
- Preparation of Fabric Dispersion Leveling Agents: Glycerol ether oleate can also be used in the preparation of fabric dispersion leveling agents, which possess superior migration, dye retardation, and dispersion properties.
2. Regulatory Parameters
The production and use of glycerol ether oleate must comply with relevant regulatory standards. For instance, the standard HG/T 5729-2020 specifies the structural formula, technical requirements, test methods, inspection rules, as well as marking, packaging, transportation, and storage of glycerol ether oleate. This standard ensures that the product meets certain quality and safety criteria.
3. Quality Standards
The quality of glycerol ether oleate is evaluated based on several parameters:
- Appearance: It should be a yellow to red-brown transparent liquid at room temperature.
- Acid Value: The acid value, measured in milligrams of potassium hydroxide per gram of sample, should be within a specified range.
- Saponification Value: The saponification value, also measured in milligrams of potassium hydroxide per gram of sample, should meet certain criteria.
- Moisture Content: The moisture content of the product should not exceed a specified percentage.
In addition, the product should be packaged in plastic containers with a net content determined by mutual agreement. It should be transported with care, kept away from moisture and rain, and stored in a cool, dry, and well-ventilated place.
Conclusion
Glycerol ether oleate is a versatile chemical with a wide range of applications in the textile and detergent industries. Its usage characteristics, regulatory parameters, and quality standards ensure that it meets the requirements for safe and effective use in various formulations. By adhering to these standards, manufacturers can ensure that their products meet the highest quality and safety criteria.
