toxicity review of diethyl phthalate (dep) cpsc,dep is a minor use plasticizer found in a variety of consumer products. oral exposure to dep resulted in oral ld50s > 5,500 – 31,000 mg/kg in rat studies, 6,172 – 8,600 mg/kg in mice studies, > 4,000 – 8,600 mg/kg in guinea pig studies, and 5,000 mg/kg in a dog study. dermal exposure to dep resulted in dermal ld50s > 11,000 mg/kg in rats
plastic products have been widely used in everyday life due to their excellent stability, low cost, and high durability (tang et al. 2022).in 2021, 390 million tons of plastics were already produced or used globally annually, and this number is expected to increase to 1.48 billion tons by 2050 (maddela et al. 2023).

permittees desiring to use a new chemical additive should: 1. check dep’s approved list of chemical additives (approved list) to ensure that the product is approved for use. 2. if a product is not found on the approved list, the permittee may complete and submit the new chemical additives request form (3800-fm-bcw0486) (request form) along with a
additives of plastics: entry into the environment and,a steep rise in global plastic production and significant discharge of plastic waste are expected in the near future. plastics pose a threat to the ecosystem and human health through the generation of particulate plastics that act as carriers for other emerging contaminants, and the release of toxic chemical additives.

in this article, we will explore the characteristics, uses, and significance of diethyl phthalate (dep). chemical structure and properties: dep has the chemical formula c12h14o4 and is a clear, colorless liquid with a faint odor. it is derived from the reaction of phthalic anhydride with ethanol, resulting in the formation of diethyl phthalate.
instructions for using dep’s approved chemical additives list,a. a specific chemical additive can be found by unchecking ‘null’ and typing in the name of the chemical additive. b. to view a list of chemical additives by manufacturer use the drop down menu to select the manufacturer’s chemical additives you would like to view. c. the approved list is sorted alphabetically by chemical additive name.
- Which processing aids are suitable for use in plastics and rubber compounds?
- These processing aids are suitable for use in plastics and rubber compounds. Plasticizers soften polymer compounds in order to improve processing, lower compound viscosity and increase the flexibility of polymer compounds.
- What are processing aids & plasticizers?
- Processing aids and plasticizers are chemical additives used in compounds to increase the plasticity, fluidity or lubrication of a material. These processing aids are suitable for use in plastics and rubber compounds.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- Why do plasticizers soften polymer compounds?
- Plasticizers soften polymer compounds in order to improve processing, lower compound viscosity and increase the flexibility of polymer compounds. Because there is a wide range of chemicals used as processing aids and plasticizers, the individual properties of each compounding material can differ greatly.
- Are dibenzoate plasticizers good for flexible PVC?
- viscosity depressing additives in flexible PVC. Dibenzoate plasticizers are valued primarily for their strong solvency. But they are defensive against phthalate plasticizers. This is because of reduced low-temperature flexibility and poor plastisol viscosity characteristics.
- Can DEHP be used in food packaging?
- It cannot be used in most products. It extracts readily into non-polar solvents (oils and fats in foods packed in PVC). Therefore, the US Food and Drug Administration (FDA) permits the use of DEHP-containing packaging only for foods that predominantly consist of water.
