The category of ‘plastics’ is an umbrella term used to describe synthetic polymers made from either fossil fuels (petroleum) or biomass (cellulose) that come in a variety of compositions and with varying characteristics. These polymers are then mixed with different chemical compounds known as additives to achieve desired properties for the plastic’s intended use (OceanCare, 2015). Plastics as litter in the oceans was first reported in the early 1970s and thus has been accumulating for at least four decades, although when first reported the subject drew little attention and scientific studies focused on entanglements, ‘ghost fishing’, and ingestion (Andrady, 2011). Today, about 60-90% of all marine litter is plastic-based (McCarthy, 2017), with the total amount of plastic waste in the oceans expected to increase as plastic consumption also increases and there remains a lack of adequate reduce, reuse, recycle, and waste management tactics across the globe (GreenFacts, 2013).

  • BMF 32 - Plasticizers: Phthalates and Adipates
    BMF 32 - Plasticizers: Phthalates and Adipates Phthalate and adipate esters are widely used as surfactants and in food and per- sonal care products as plasticizers. Phthalates and adipates are also found in food as a result of leakage into food containers. Chiron offers a wide range of analytically pure deuterated and native phthalates and adipates, as well as mixes. Custom made mixes are available on request. Metabolites: Phthalate biomarkers It has been shown that dialkylphthalates are metabolized in the body to endocrine-active monoalkyl- phthalates, and appears to be linked with the prevalence of abdominal obesity and insulin resistance in men. General information Neat Compounds: Most of the compounds are also available in neat form. Please inquire for an offer. Custom solutions: Please inquire for custom solution of the plasticizers. Please inquire if you have need for others. Other labelled plasticizers are available upon request (deuterium or 13 C).
