What is diisononyl phthalate used for?
DINP is one of the phthalates most frequently used in plastic products. DINP is used in various types of plastic consumer products, including: Some polyvinyl chloride (PVC, vinyl) flooring, materials used in automobile interiors, wire and cable insulation, gloves, tubing, garden hoses, and shoes.
What is dicyclohexyl phthalate used in?
Dicyclohexyl phthalate (CASRN 84-61-7) is a granular solid at room temperature. The primary use for dicyclohexyl phthalate is as a plasticizer in adhesives and plastic and rubber products and resins.
How is DINP produced?
DINP is produced by esterification of phthalic anhydride with isononyl alcohol (= isononanol) in a closed system. The reaction rate is accelerated by elevated temperatures (140-250 °C) and a catalyst.
Where is DINP found?
DiNP is primarily used to produce flexible plastics and has replaced di-2-ethylhexyl phthalate (DEHP) in some plastics, though not in medical products. DiNP is widely used in such products as toys, flooring, gloves, drinking straws, garden hoses, and in sealants used for food packaging.
What is plasticizer in polymer?
Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating.
Is DINP soluble in water?
The water solubility of DINP is < 0.001 mg/l, which is well below the cut-off value of 1 mg/l.

What are phthalates?
Phthalates are a group of chemicals used to make plastics more durable. They are often called plasticizers. Some phthalates are used to help dissolve other materials. Phthalates are in hundreds of products, such as vinyl flooring, lubricating oils, and personal-care products (soaps, shampoos, hair sprays).
How is DINP absorbed?
Exposure to DIDP or DINP in certain workplaces may occur by skin contact or by inhalation. Skin may come into contact with DIDP, or with formulations or end products containing it, but absorption is very low through the skin.
What are the 3 types of plasticizers?
Explore various plasticization methods along with their benefits and learn how to select the right plasticizer from the main chemical classes of plasticizers: phthalates, benzoates, adipates etc.
Do plasticizers increase viscosity?
A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, or to decrease friction during its handling in manufacture.
What is DINP and DIDP?
DIDP and DINP are viscous, oily liquids that are soluble in fat and not very soluble in water. They are not very volatile so they do not vaporise readily into the atmosphere.
What is Dicyclohexyl ether?
The Dicyclohexyl ether molecule contains a total of 36 bond(s) There are 14 non-H bond(s), 2 rotatable bond(s), 2 six-membered ring(s) and 1 ether(s) (aliphatic).
What is diethyl ether used for?
Diethyl ether (CAS 60-29-7) is a component of starting fluids and is used as a solvent in the manufacture of synthetic dyes and plastics. Because of its characteristics diethyl ether was widely used in many countries as an anesthetic agent, but was then replaced by other substances in the 1960s.
How do you test for phthalates?
All plastics are not the same. One easy way to recognize plastic toys, clothing, bottles, food and beverage storage containers, and/or food wrap that may contain phthalate compounds is to look for the number 3 inside the universal recycling symbol usually molded into the plastic on the bottom of the product.
How do you remove phthalates from water?
The best way to remove phthalates from your water is with an NSF/ANSI 58 certified reverse osmosis system.
…
You can:
- Be mindful of the products you use.
- Test your water for phthalates.
- Filter the chemicals out with a reverse osmosis water filter.
Can Diisononyl phthalate be absorbed through skin?
DINP is 10 times less absorbed through the skin than DEHP (EU, 2003), and human skin is 4 times less permeable to phthalates than rat skin (Scott et al., 1987). The absorption rate of the DINP level in the grip [F] was determined based on the adjusted concentration [E].
Can DEHP be absorbed through the skin?
DEHP can be absorbed through skin. Approximately 2% of a dermal dose is absorbed in humans (6% in rats and 19–>50% in hairless guinea pigs).
Why is glycerol used as plasticizer?
Glycerol is the most common plasticiser due to its high plasticising capacity and thermal stability at processing temperatures.
What makes a good plasticizer?
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer.
Is diethyl ether soluble in water?
Diethyl ether, or ethoxyethane, or just plain ether, is a colorless liquid at room temperature, having a boiling point of 34.6ºC. Unlike dimethyl ether and ethyl methyl ether, it is only slightly soluble in water, with 6.9 grams of diethyl ether dissolving in 100 mL of water.
Is diethyl ether miscible in water?
Answer and Explanation: Water and diethyl ether are miscible. It is because the oxygen group in diethyl ether makes it polar. Since water is a polar solvent, diethyl ether and water will be miscible.
How do you test phthalates in water?
Test your water for phthalates. Filter the chemicals out with a reverse osmosis water filter.
One way to identify them is to look for the acronyms of some of the most common phthalates on product packaging, including:
- BBP.
- DBP.
- DEHP.
- DIBP.
- DINP.
- DNOP.
- DNPP.
How do you test for BPA and phthalates?
What are we testing for in urine? Our urine test measures your near-term exposure for bisphenol-A (BPA) and phthalates through their metabolites. The levels detected in urine are typically indicative of exposure in the 24-48 hours prior to collecting the sample.
Does boiling water remove phthalates?
Boiling water effectively removed phthalate esters from tap water. Thus, this process was recommended to local residents to reduce certain potential thyroid related risks through drinking water.
