2、Ethyl acetate
The biological half-life value of the conversion of ethyl acetate to ethanol was found to be between 5 and 10 min. At doses higher than 1.6 g kg-1 in rats the rate of hydrolysis exceeded the ethanol oxidation leading to the ethanol accumulation in the vascular system.

NIST subscription sites provide data under the NIST Standard Reference Data Program, but require an annual fee to access. The purpose of the fee is to recover costs associated with the development of data collections included in such sites. Your institution may already be a subscriber.
5、Sorbitan Ester Nonionic Lipophilic Surfactants, Sorbitan Fatty Acid
An HLB value less than 6 indicates that the surfactant favors W/O emulsion; an HLB value greater than 8 favors O/W emulsion. HLB values in between 7 and 9 indicate that the surfactants are good wetting agents.
Hydrophilic
Hydrophilic-Lipophilic Balance (HLB) is defined as a numerical system that describes the relationship between the water-soluble and oil-soluble parts of a nonionic surfactant, with HLB values ranging from 1 to 30.

The Benefits of Using Hydrophilic
Bond Elut HLB demonstrates good recovery for a panel of targets from polar to non-polar with MeOH elution. For some non-polar targets, stronger solvents such as 1:1 MeOH/CAN, CAN and ethyl acetate can be useful to improve recovery.

Ethyl Acetate, also known as acetate or vinegar essence, is an organic compound with the chemical formula CH3COOC2H5. It is a colorless, volatile liquid with a smell similar to vinegar. In industry, ethyl acetate is widely used as a solvent and synthetic intermediate for manufacturing coatings, adhesives, plastics, rubber and other macromolecules.
The HLB value of ethyl acetate refers to the degree of dispersion of oil droplets in the emulsion formed after mixing with water. The higher the HLB value, the easier it is for the substance to dissolve in water, forming a stable emulsion. The HLB value of ethyl acetate is 4.9-6.0, which means that it has relatively strong hydrophilicity in aqueous solution and can form better emulsification with water.
The HLB value of ethyl acetate is related to its chemical structure. Ethyl acetate is produced by the reaction of ethylene and acetyl (CH3COO-) provides hydrophilicity, while the ethylene group (C2H4) provides hydrophobicity. When ethyl acetate is mixed with water, the acetyl group will face towards water molecules, making the entire molecule tend to the water phase, thus reducing the interface tension and forming a stable emulsion.
The HLB value of ethyl acetate is significant in its application areas. In the paint industry, ethyl acetate is often used as a solvent and additive to help the paint better adhere to the substrate surface. In the adhesive industry, it acts as a solvent or plasticizer to improve the flexibility and bonding force of the adhesive. In the plastics industry, ethyl acetate can be used as a plasticizer to improve the plastic's plasticity and temperature resistance.
the HLB value of ethyl acetate also determines its performance in specific applications. In situations requiring high stability and low volatility, such as food packaging materials or cosmetics, ethyl acetate may not be the best choice. In these applications, other types of solvents or plasticizers are usually required to meet specific performance requirements.
the safety of ethyl acetate is also a factor that needs to be considered. Although ethyl acetate itself is non-toxic, some by-products may be produced during production, such as acetyl anhydride, acetone and other toxic substances. when using ethyl acetate, relevant safety regulations should be followed, and necessary protective measures should be taken to ensure the safety of operators.
the HLB value of ethyl acetate plays an important role in its application in various fields. Understanding the HLB value of ethyl acetate and its interaction with other chemicals can help us better utilize this resource to meet the needs of different industrial fields. In future research, more about the application and modification methods of ethyl acetate can be explored to expand its application scope and enhance its value in industrial production.
