Compounds: Compounds that contain
at least one tin-carbon bond are referred to as organotins. Organotin compounds
find use as catalytic agents, industrial biocides, plastic stabilizers, glass
coatings, antifouling paints and pesticides among its major commercial
applications. These compounds pollute the environment and are harmful to
aquatic life. Even at very low concentrations, organotins are extremely toxic
to marine and freshwater organisms. The primary source of exposure to humans of
organotin compounds is from seafood and the most common harm is damage to the
immune system. Tributyltin (TBT) and triphenyltin (TPhT) are the most common
organotins used in the textile and apparel industries, because DBT is mainly
used as a stabilizer in PVC applications and for plastisol prints instead.
Organotins are restricted by Japan, South Korea and Taiwan.
Phthalates: Most commonly used as a softener for products made
from polyvinyl chloride (PVC) these are a ubiquitous class of compounds.
Phthalate is a term referring to the di-ester derivatives of phthalic acid and
so is a group of different compounds, although they are structurally related.
commerce makes diverse use of phthalates. One common use is to soften PVC
products that require flexibility, for example blood bags and children's toys.
Phthalates are also found in many consumer products, such as textiles,
footwear and cosmetics because they are used as lubricating oils, solvents,
fixatives and detergents. Its very diversity inevitably creates human exposure
opportunities. Plastisol prints on garments often contain phthalates and they
are also present in PVC-based materials that are used for coating, shoe soles
and in many accessories produced by the garment and footwear industries. Recent
studies have shown that phthalate exposure can amend estrogen levels in the hormone
systems of humans and animals, giving rise to serious health problems like
cancers and impairments to the reproduction and development. Phthalates are
restricted by Egypt and South Korea.
hazards like those described above are regularly communicated and the public is
becoming more and more aware of the dangers they pose. When it comes to
compliance with chemical restrictions it is not enough to simply get your
merchandise into the market. Enforcing prudent chemical safety measures in your
supply chain also demonstrates your social responsibility to the public and
positively reflects on your brand image.
