How To Choose a Prenatal Vitamin Without Lead, Pesticides, or
This lead to a $1.75-million settlement and the company agreeing to a rigorous testing protocol that would further reduce the level of lead in its prenatal vitamins. The company now has to test its prenatal vitamins every six months to determine if the vitamins contain lead in amounts greater than 0.2 micrograms per day.

This is a mix of limestone, PVC, and plasticizer. It’s low in offgassing due to the high amount of limestone – it’s usually 60-80% limestone and the rest is PVC and plasticizer with no foaming agent. Look out for companies that call this a “limestone core” without mentioning the PVC/vinyl content (it’s still there).
Plasticizer
Some common phthalate plasticizers are: Low Molecular Weight Ortho Phthalates Dimethyl phthalate (DMP), used in fragrances, as an insect repellent, and in several industrial processes as a solvent/carrier Diethyl phthalate (DEP), used in fragrances as a carrier and extender/fixative Diisobutyl phthalate (DIBP)
Shipping Plasticizers: Classifications, Examples, Benefits
Phthalate Plasticizers. Phthalate plasticizers contain useful properties, including low volatility, weather-resistance, low solubility in water, and remarkable resistance to biodegradation. These properties make it useful for a variety of purposes. However, its compatibility with the PVC polymer is its trump card.

Plasticizers, in general, pose a much greater concern for health than BPA's. Pool liners also used to contain heavy metals such as lead and arsenic as well as formaldehyde, styrenes and other toxic chemicals which are restricted in use, or altogether banned, from modern day manufacturing processes.

- 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.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- Are phosphates a good plasticizer for PVC?
- Phosphates are primary plasticizers for PVC. They can be utilized as sole plasticizers or in a cost-optimized blend. Triaryl phosphates show excellent flame retardancy with low volatility. However, they have poorer low-temperature flexibility.
- Does a PVC plasticizer need to be labeled in California?
- If it can be demonstrated that a flexible PVC product containing (Proposition 65 listed) DEHP plasticizer, for example, cannot expose a consumer to more than the maximum acceptable daily limit of DEHP (established by the state of California), no labeling is required in California.
