DCHP (Dicyclohexyl Phthalate)CAS 84-61-7
Solid-at-room-temperature phthalate used in low-volatility plasticizer applications.
Toxic Chemical Databases
Substance-specific listings — these flags are for DCHP alone, not for the broader family.
Chemical Type
Cyclohexyl Phthalate
Chemical Description
DCHP differs from the liquid phthalates — at room temperature it is a crystalline solid. Used in nitrocellulose-based finishes, some printing inks, and specialty rubber compounds. EU REACH added DCHP to the SVHC Candidate List for reproductive toxicity and endocrine-disruption properties; read-across data from the closer-studied phthalate analogs supports the classification.
Biological Activity
Severity scores specific to this substance, NOT the parent family average. Differences between siblings are real and meaningful.
Top Health Consequences
- REACH SVHC — reproductive toxicity and endocrine disruption
- Read-across hazard from short-chain phthalate family
- Lower volatility than DBP/DEHP but persistent in finished products
Pathways of Exposure
- Ingestion of dust from treated rubber and printed materials
- Inhalation of dust during processing

How We Keep DCHP Out of a House
Avoiding DCHP is only half of it. The replacement has to work in a mold free, airtight, PHPP-modeled assembly as well — and finding materials that do both is most of what we do.
If you want a house specified this way from the start, or an existing house assessed for what is already in it, that is the work we do. Earth Bound Homes builds in Los Gatos, San Jose, Santa Clara County and across the San Francisco Bay Area.
