What are Phthalates: Chemical Free Living

What are phthalates?

Phthalates are commonly used in fragranced products like skin moisturizers, soaps, shampoos, hair sprays, and perfumes to help the scent linger longer. Phthalates are a ubiquitous class of chemicals used in softeners, solvents, fragrances, plasticizers, and PVC or polyvinyl chloride products [2]. They’re used to make plastics more flexible and less prone to breakage [3].

What products are phthalates in?

Phthalates are regularly found in fragranced cosmetic & personal care products and nail polish in the United States. They’re currently found in PVC children’s toys, backpacks, food packaging products like cling wrap, medical devices, building materials such as water pipes, vinyl flooring, adhesives, inks, dyes, mosquito repellents and other personal care products [2]. They are also used as an ingredient in nail polish [1] [2] [3].

How to tell if a product has phthalates

Phthalates are typically not listed on ingredient labels. However products that contain “fragrance” on the label are likely to contain phthalates [1]. The one word “fragrance” can include more than 100 different chemicals including phthalates. The reason is that manufacturers are not required to disclose the various chemicals that make up a fragrance. This is because fragrances are considered to be “trade secrets“.

Risks associated with phthalates

Phthalates can have long-term health consequences for both adults and children. They have been banned for use in cosmetics in the European Union [1]. Though scientific studies were substantial enough for the European Union to ban their use in cosmetics, this toxic ingredient remains in common use in a variety of products throughout the United States. In January of 2012, Congress banned the use of more than 0.1% of three types of phthalates (DEHP, DBP, and BBP) from children’s toys and childcare products. Three additional types of phthalates (DINP, DIDP, and DnOP) were also banned temporarily. These phthalates, though banned in children’s products, are still widely used in cosmetics [2]. Health risks for phthalates are broad and significant including:

  • Cancer – According to The National Toxicology Program, phthalates are “reasonably anticipated to be a human carcinogen”.
  • Negatively impacts human reproduction and development
  • Negatively impacts normal human development
  • Newborn males exposed to high levels of DIP through the use of medical feeding tubes or other medical devices may be at risk of abnormal development of the male reproductive system according to the National Institute of Environmental Health Sciences.
  • Birth defects
  • Respiratory problems
  • Behavioral problems in children
  • Premature birth
  • Decreased sperm counts and damaged sperm [2] [3]

How to avoid phthalates

Avoid phthalates by reading ingredient labels and avoiding any listing “fragrance” on the label [2]. Avoid products that contain DEHP, DBP, BBP, DINP, DIDP, and DnOP. Phthalate-free alternatives include citrates, sebacates, adipates, and phosphates [4]. Also avoid products that contain DBP and plastics with recycling codes 3, 6, & 7.
