Dibutyl phthalate (DBP) under REACH

C16H22O4 · 邻苯二甲酸二丁酯

Status: Restricted. Dibutyl phthalate is fully registered under REACH and is **subject to multiple overlapping EU restriction + authorisation regimes**. **Distinguishing pattern: DBP is a phthalate plasticiser produced by esterification of phthalic anhydride with n-butanol; major historical downstream uses were PVC plasticiser + cellulose-based film (cellulose acetate / nitrate) + nail polish + adhesives + sealants + coating-film-former + lubricants. Use in PVC has been progressively replaced by higher-molecular-weight phthalates (DEHP successor + DINP + DIDP) and non-phthalate plasticisers (DOTP + adipates + trimellitates) due to reproductive-toxicity classification.** **REACH Annex XIV authorisation list: DBP was added to Annex XIV via Commission Regulation (EU) No 143/2011 of 17 February 2011 with latest application date 21 August 2013 and sunset date 21 February 2015** (sourced to EUR-Lex eli/reg/2011/143 + ECHA Annex XIV authorisation list https://echa.europa.eu/authorisation-list to verify). **REACH SVHC candidate list: DBP added 28 October 2008 as toxic for reproduction Repr. 1B** (sourced to ECHA candidate list https://echa.europa.eu/candidate-list-table to verify). **REACH Annex XVII Restriction Entry 51: DBP + DEHP + BBP + DIBP banned in toys + childcare articles at >0.1% by mass + consumer articles with skin contact at >0.1% by mass effective 7 July 2020 via Commission Regulation (EU) 2018/2005** (sourced to EUR-Lex eli/reg/2018/2005 to verify). **EU Toy Safety Directive 2009/48/EC: phthalates including DBP banned in toys + childcare articles at >0.1% by mass per Annex II Part III (3)** (sourced to EUR-Lex to verify). DBP is classified Repr. 1B + Aquatic Chronic 4 + suspected endocrine disruptor.

Dibutyl phthalate is fully REACH-registered but **subject to FOUR overlapping EU restriction + authorisation regimes: Annex XIV authorisation (sunset 21 February 2015 per Reg (EU) 143/2011) + SVHC candidate list (28 October 2008) + Annex XVII Restriction 51 (toys + childcare + skin-contact <0.1% by mass effective 7 July 2020 per Reg (EU) 2018/2005) + EU Toy Safety Directive 2009/48/EC + EU Cosmetic Products Regulation Annex II prohibition**. Repr. 1B + suspected endocrine disruptor. **Annex XIV authorisation is the practical EU placing-on-market compliance pivot for any use in scope; B2C placement in toys / childcare / skin-contact / cosmetics is BANNED.** Major Chinese producers: Beijing Yanshan Petrochemical + Anhui Yifeng + Hangzhou Hangwei + Jiangsu Pengrun + Shandong Hongxin Chemicals.

Classifications under this regime

  • Repr. 1B: H360Df (may damage the unborn child + suspected of damaging fertility) + Aquatic Chronic 4: H413 per harmonised CLP (verify exact harmonised classification against ECHA Annex VI to CLP Table 3.1 before relying)
  • **REACH Annex XIV authorisation list: DBP added via Commission Regulation (EU) No 143/2011, sunset date 21 February 2015** (sourced to ECHA https://echa.europa.eu/authorisation-list to verify; placing on EU market for use in scope without authorisation is prohibited)
  • **REACH SVHC candidate list: DBP added 28 October 2008 as Repr. 1B** (sourced to ECHA https://echa.europa.eu/candidate-list-table to verify)
  • **REACH Annex XVII Restriction Entry 51: DBP + DEHP + BBP + DIBP banned in toys + childcare articles + consumer articles with skin contact at >0.1% by mass effective 7 July 2020 via Commission Regulation (EU) 2018/2005** (sourced to EUR-Lex eli/reg/2018/2005 to verify)

Restrictions and conditions of use

  • **REACH Annex XIV authorisation list: DBP placed on EU market for use in scope without authorisation is PROHIBITED; sunset date 21 February 2015 per Commission Reg (EU) 143/2011 (verify against ECHA https://echa.europa.eu/authorisation-list)**

Importer obligations

A non-EU producer cannot register directly under REACH. The EU importer of record must hold a registration or rely on an Only Representative (OR). **Annex XIV authorisation: placing on EU market for use in scope without authorisation is PROHIBITED; only authorised uses (per Commission authorisation decisions) are permitted.** **Annex XVII Restriction 51: B2B / industrial-only customer declaration mandatory; B2C consumer placement BANNED in toys + childcare + skin-contact articles at >0.1% by mass.** **EU Toy Safety Directive: BANNED in toys + childcare articles.** Major non-EU producers: ExxonMobil (USA Houston TX), Eastman Chemical (USA Kingsport TN), KH Neochem (Japan), JSR (Japan). Major Chinese DBP producers: Beijing Yanshan Petrochemical (Sinopec) + Anhui Yifeng + Hangzhou Hangwei + Jiangsu Pengrun + Shandong Hongxin Chemicals; verify each producer-site pair against the producer's public website before relying.

Required documents

  • REACH registration number on EU side
