In the United States, the growing concern over BPA exposure in infants in recent years has led the manufacturers of plastic baby bottles to stop using BPA in their bottles. The FDA banned the use of BPA in baby bottles and sippy cups (July 2012) as well as the use of epoxy resins in infant formula packaging. [204]

Bisphenols A (BPA), F (BPF) and S (BPS) have been shown to be endocrine disruptors, potentially relating to adverse health effects. [3] [6] Due to its high production volumes, BPA has been characterised as a "pseudo-persistent" chemical, [7] leading to its spreading and potential accumulation in a variety of environmental matrices, even though it has a fairly short half-life.
BPA has been found to interact with a diverse range of hormone receptors, in both humans and animals. [78] It binds to both of the nuclear estrogen receptors (ERs), ERα and ERβ. BPA is a selective estrogen receptor modulator (SERM), or partial agonist of the ER, so it can serve as both an estrogen agonist and antagonist.
The same goes for vitamin B12 and ferritin (a form of iron) which women may not get enough of via food, particularly those following plant-based or vegetarian diets.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Studies have shown that at temperatures above 70 °C, and high humidity, polycarbonate will hydrolyze to bisphenol A (BPA). After about 30 days at 85 °C/96% RH, surface crystals are formed which for 70% consisted of BPA. [34] BPA is a compound that is currently on the list of potential environmental hazardous chemicals.
The over-60s usually have different skincare concerns, such as drier and thinner skin, so it's important to choose products with ingredients that focus on those symptoms.
