Parabens (Methyl, Propyl, Butyl, and Ethyl Paraben)
Parabens are one of many toxic environmental chemicals. They are added to plastics to impart resilience and flexibility. Smaller phthalates are used to prolong the length of time that a scented product maintains its fragrance. They are used widely as an antimicrobial, a preservative and flavorant in food, as well as cosmetic and pharmaceutical formulations to increase shelf life.

Impact on Health
- Allergic contact dermatitis
- Estrogenic activity
- Decreases testosterone levels and sperm count in animal studies
- Alkyl esters of para-hydroxybenzoic acid, parabens, are hydrolyzed to para-hydroxybenzolate, the main metabolite of parabens, via tissue esterases found in skin, subcutaneous fat, liver and kidney.
- Bioaccumulation of parabens may result from chronic exposure.
- Thyroid dsyfunction
- Liver and kidney toxicity
- Changes in behaviour and cognition.
