Bis(2-ethylhexyl) adipate, also known as DEHA or DOA, has the CAS number 103 - 23 - 1. It is a colorless to light - yellow, oily liquid with a slight odor. The molecular formula of Bis(2-ethylhexyl) adipate is C₂₂H₄₂O₄, and its molecular weight is approximately 370.57 g/mol. This compound has a density of around 0.927 g/cm³ at 20°C. The boiling point is about 214°C at 5 mmHg, and it has a flash point of 196°C (closed cup). It is insoluble in water but soluble in most organic solvents such as ethanol, ether, and acetone.
- **Plasticizer**: One of the primary uses of Bis(2-ethylhexyl) adipate is as a plasticizer in the plastics industry. It can be added to polyvinyl chloride (PVC) products to increase their flexibility, durability, and workability. PVC products with Bis(2-ethylhexyl) adipate as a plasticizer are widely used in the manufacturing of cables, hoses, and vinyl flooring.
- **Lubricant**: In the lubricant industry, it can be used as a synthetic lubricant or as an additive in lubricant formulations. It helps to reduce friction between moving parts, improve the anti - wear performance of lubricants, and extend the service life of machinery.
- **Cosmetics and Personal Care**: Bis(2-ethylhexyl) adipate is also used in cosmetics and personal care products. It can act as an emollient, making the skin feel soft and smooth. It is often found in lotions, creams, and makeup products.
- **Plastic Production**: When using Bis(2-ethylhexyl) adipate as a plasticizer in PVC production, it should be added during the plastic mixing process. The appropriate dosage depends on the specific requirements of the final product, usually ranging from 5% to 50% of the total PVC formulation. Mixing should be carried out under controlled temperature and pressure conditions to ensure uniform dispersion.
- **Lubricant Formulation**: In lubricant production, it can be blended with base oils and other additives. The proportion of Bis(2-ethylhexyl) adipate in the lubricant formula typically ranges from 1% to 20%, depending on the desired performance of the lubricant, such as viscosity and anti - wear properties.
- **Cosmetics and Personal Care**: In the formulation of cosmetics, it should be added to the oil phase of the product during the manufacturing process. The dosage is usually between 1% and 10%, depending on the type of cosmetic product and the desired skin - feeling effect.
- **Case 1: PVC Cable Production**
A cable manufacturing company used Bis(2-ethylhexyl) adipate as a plasticizer in their PVC cables. By adding 30% of Bis(2-ethylhexyl) adipate to the PVC formulation, they found that the cables became more flexible, which made them easier to install. The low - temperature flexibility of the cables was also improved, allowing them to be used in cold environments without cracking. Additionally, the cables had better electrical insulation properties, reducing the risk of electrical failures.
- **Case 2: Industrial Lubricant**
An industrial machinery manufacturer incorporated Bis(2-ethylhexyl) adipate into their lubricant formulation at a ratio of 15%. After using this lubricant in their large - scale machinery, they observed a significant reduction in friction and wear of the moving parts. The machinery ran more smoothly, and the maintenance frequency was reduced, resulting in cost savings for the company.
- **Case 3: Skin Care Lotion**
A cosmetic company added 5% of Bis(2-ethylhexyl) adipate to their skin care lotion. Through consumer testing, they found that the lotion had a better spreadability and left the skin feeling softer and more moisturized compared to the previous formulation without Bis(2-ethylhexyl) adipate. This led to an increase in customer satisfaction and product sales.
