Dibutyl Phthalate (CAS no. 84-74-2)

Dibutyl Phthalate (DBP) is a synthetic compound commonly used as a plasticizer, which is a substance that is added to materials to increase their flexibility, transparency, durability, and longevity.

Usage in Cosmetics:
In the realm of cosmetics, DBP is often utilized as a solvent for dyes and as a plasticizer in nail polish, providing the polish with flexibility upon drying and thus preventing it from becoming brittle. It helps to maintain the smooth and sleek appearance of the nail polish, making the product more appealing and effective.

Skin Sensitivities and Allergies:
Dibutyl Phthalate is known to be a potential skin irritant, especially for those with sensitive skin. Prolonged exposure may cause skin dryness or cracking. It can also potentially cause allergic skin reactions in some individuals, although the frequency and severity of such reactions can vary.

Other Risks:
Apart from skin sensitivities, there are other health concerns associated with DBP. It has been linked to reproductive issues, hormonal disruptions, and developmental problems in children. Some studies have also suggested a potential connection between exposure to DBP and cancer.

Regulatory Status:
In California, as per Assembly Bill No. 496, CHAPTER 441, the manufacture, sale, delivery, holding, or offering for sale of cosmetic products containing Dibutyl Phthalate is prohibited, effective from January 1, 2025. This ban reflects growing concerns about the safety of DBP, particularly its potential health impacts beyond skin irritation.

Summary of Ban:
The prohibition on DBP in cosmetic products in California is aimed at safeguarding public health, particularly in light of the ingredient's potential to cause skin irritations, hormonal disruptions, and other health issues. This measure reflects a broader trend of increasing scrutiny and regulation of potentially harmful ingredients in cosmetics, to ensure the safety and well-being of consumers, especially those with sensitive skin.
