Science
Mechanism of Action
DBP permeates the skin barrier, metabolizing into monoesters, and can induce apoptosis of keratinocytes and fibroblasts via caspase-3 activation. It also acts as an endocrine disruptor and can trigger inflammatory responses and allergic reactions, particularly in sensitive skin.

Key findings
- 01 Human skin permeation rates average 0.07-0.1 µg/cm²/hr.
- 02 Dermal exposure to 4.0 mg/kg/body DBP in mice, with sensitization, led to substantial histological and immunological skin changes.
- 03 DBP has been shown to induce apoptosis in skin keratinocytes and fibroblasts.

Safety
Safety Profile
While CIR deemed DBP safe in 1985/2002/2005 with a high margin of safety, it is banned in cosmetics by the EU and California (effective 2025). DBP is classified as an endocrine disruptor and reproductive/developmental toxicant, with FDA recommending avoidance in certain drug products.

Verdict
Dibutyl Phthalate should be avoided due to its classification as an endocrine disruptor and reproductive toxicant, its potential for skin irritation and sensitization, and its prohibition in cosmetics by major regulatory bodies.
