What Is Propylene Glycol Monobutyl Ether (PGBE / 1-Butoxy-2-propanol)?
- Not listed as US EPA HAP (Hazardous Air Pollutant, Clean Air Act Section 112(b)) - unlike EGBE (CAS 111-76-2, HAP listed); eliminates EGBE-attributable HAP emission monitoring and reporting obligations for large US coating, cleaning, and industrial manufacturing facilities. Confirmed via US EPA CompTox Dashboard (DTXSID9021908). Sinolook provides formal non-HAP confirmation letters for EPA air permit applications and supply chain compliance records.
- Not classified as Repr. 1B/2 under EU CLP - no REACH Annex XVII consumer product restriction; no CMR designation; not SVHC listed. Fully eligible as co-formulant in EU-authorized plant protection products under Regulation (EC) No 1107/2009. P-series (propylene glycol) backbone reduces hemolysis and reproductive toxicity tendency observed in shorter-chain E-series solvents (EGME Repr.1B, EGEE Repr.1B).
- EGBE-equivalent solvency - nearly identical boiling point (165–175 °C vs EGBE 168–173 °C), matching flash point (~61 °C), same density (0.901 g/cm³), full water miscibility; direct near-drop-in non-HAP substitute for EGBE in most coating, cleaning, and industrial formulations. Also known as Dowanol PnB (Dow Chemical commercial grade). Precursor to PGBEA (CAS 131737-44-5) - a non-HAP companion retarder for automotive and industrial coatings.
Propylene Glycol Monobutyl Ether (PGBE, CAS 5131-66-8) - also known as 1-Butoxy-2-propanol (IUPAC) or Dowanol PnB - is produced by addition of n-butanol to propylene oxide under catalytic conditions, yielding predominantly the 1-butoxy-2-propanol isomer (secondary hydroxyl). Molecular formula C₇H₁₆O₂, MW 132.20 g/mol. PGBE belongs to the P-series (propylene glycol ether) family - structurally analogous to E-series glycol ethers but derived from propylene oxide rather than ethylene oxide, with a methyl-substituted backbone that imparts meaningfully improved toxicological properties while retaining comparable solvency to its E-series counterpart EGBE (CAS 111-76-2, Butyl Cellosolve).
The P-series methyl side-group on the propylene glycol backbone reduces hemolysis tendency and reproductive toxicity risk observed in shorter-chain E-series solvents - confirmed by ECHA substance dossier (EC 225-878-4) and GESTIS occupational safety database (IFA/DGUV). PGBE is fully miscible with water and all common organic solvents. Its boiling point (165–175 °C) and flash point (~61 °C) position it in the same evaporation zone as EGBE, enabling direct or near-direct substitution in the majority of waterborne coating, cleaning, and industrial formulations where EGBE's HAP listing creates US compliance burden.
PGBE is also available in its acetate form: Propylene Glycol Monobutyl Ether Acetate (PGBEA, CAS 131737-44-5) - esterification with acetic acid yields a slower-evaporating companion retarder for high-performance automotive and industrial coatings. The PGBE + PGBEA solvent pair provides a fully non-HAP alternative to the EGBE + EGBEA combination. Sinolook supplies both products. Purity ≥99.0%, ISO 9001 and ISO 14001 certified, full COA, GHS SDS, REACH documentation. Class 3 DG (UN 3272, PG III).
Key Performance Advantages of PGBE / Propylene Glycol Monobutyl Ether
Six properties define PGBE's strategic market position - the only P-series butyl glycol ether that simultaneously delivers EGBE-equivalent solvency while providing non-HAP US status, non-Repr.1B EU status, no CMR classification, and EU 1107/2009 agrochemical co-formulant eligibility.
🔄 Near-Drop-In Non-HAP EGBE Substitute - Matching Physical Properties
PGBE offers the closest physical property match to EGBE of any commercially available non-HAP solvent: boiling point 165–175 °C vs EGBE 168–173 °C (within 5 °C); flash point ~61 °C - identical; density 0.901 g/cm³ - identical; full water miscibility - matching. Enables direct or near-direct substitution in the majority of waterborne coating, cleaning, and industrial formulations. In cleaning concentrate formulas, substitution is typically weight-for-weight with minor adjustments to fragrance masking and surfactant ratios. In waterborne coatings, minor co-solvent ratio adjustments may be needed. No other non-HAP P-series glycol ether (PGME, PGPE, DPGME, DPGBE) simultaneously matches EGBE on boiling point, flash point, and density - PGBE is unique in this position.
🇺🇸 Not US HAP Listed - Preferred for US Manufacturing Compliance
PGBE is confirmed not listed as a Hazardous Air Pollutant (HAP) under US Clean Air Act Section 112(b) - directly verifiable via US EPA CompTox Dashboard (DTXSID9021908). Unlike EGBE (HAP listed), PGBE carries no US air emission monitoring, reporting, or MACT obligations under 40 CFR Part 63. Large US coating, cleaning, and industrial product manufacturing facilities using EGBE may be subject to NESHAPs compliance and annual HAP emission reporting; transitioning to PGBE removes EGBE from the facility's HAP raw material inventory, potentially reducing air permit complexity and eliminating periodic HAP reporting. Sinolook provides formal non-HAP confirmation letters for EPA air permit applications, supply chain audit records, and government procurement requirements.
🇪🇺 Non-Repr.1B + EU 1107/2009 Eligible - P-Series Toxicological Advantage
PGBE is not classified as Repr. 1B/2 under EU CLP - no reproductive toxicant designation, no REACH Annex XVII consumer restriction, no CMR classification, not SVHC listed. P-series methyl-substituted backbone structurally reduces hemolysis tendency and reproductive toxicant potential vs. shorter-chain E-series solvents - confirmed by ECHA dossier (EC 225-878-4) and GESTIS (IFA/DGUV). Fully eligible as co-formulant in EU-authorized plant protection products under Regulation (EC) No 1107/2009 - unlike EGME (Repr. 1B, restricted) and EGEE (Repr. 1B, restricted). The combination of non-HAP (US) + non-Repr.1B (EU) makes PGBE the uniquely dual-market-compliant butyl solvency alternative.
🎨 Coalescing Agent & Coupling Solvent - Waterborne Coatings
In waterborne architectural and industrial coating systems, PGBE performs the same coalescing and coupling functions as EGBE - reducing MFFT of latex polymer dispersions, enabling defect-free film coalescence at low temperatures, extending the wet edge, improving flow and leveling. Boiling point 165–175 °C provides a comparable coalescence window to EGBE. Formulation substitution is typically minor - modest co-solvent ratio adjustments and VOC recalculation. For US coating manufacturers, switching from EGBE to PGBE eliminates EGBE-attributable HAP inventory and potential NESHAPs obligations, reducing compliance cost and air permit complexity. Fully compatible with acrylic, latex, alkyd, and polyurethane resin systems.
🧹 Grease-Cutting Active - Non-HAP Cleaning Products
In household, institutional, and industrial cleaning formulations, PGBE delivers EGBE-equivalent grease-cutting and coupling performance - rapid dissolution of greasy soils, fatty residues, adhesive stains, and organic deposits; full water miscibility; compatibility with alkaline builders, chelating agents, surfactants, and fragrances; minimal residue after evaporation. The critical US regulatory advantage: PGBE's non-HAP status means US cleaning product manufacturing facilities are not subject to MACT standards or annual HAP emission reporting that EGBE's HAP listing imposes under 40 CFR Part 63 - especially valuable for large-volume institutional and industrial cleaning product manufacturers operating under Title V air permits.
⚖️ PGBEA Precursor - Fully Non-HAP EGBE/EGBEA Alternative Pair
PGBE is the direct precursor to Propylene Glycol Monobutyl Ether Acetate (PGBEA, CAS 131737-44-5) - esterification with acetic acid yields a slower-evaporating companion retarder for high-performance automotive refinishing and industrial maintenance coatings. PGBEA shares PGBE's non-HAP status - making the PGBE + PGBEA solvent pair a fully non-HAP alternative to the EGBE + EGBEA combination. This non-HAP pair strategy is particularly valuable for automotive refinish coating manufacturers and industrial coating formulators serving US facilities with HAP air permit constraints. Sinolook supplies PGBEA as a companion product - combined quotation available.

Frequently Asked Questions About PGBE / Propylene Glycol Monobutyl Ether
Technical and commercial questions from B2B buyers in coatings, cleaning, agrochemicals, and industrial applications - especially those evaluating PGBE as an EGBE substitute or Dowanol PnB alternative.
What is Propylene Glycol Monobutyl Ether (PGBE) and what is it used for?
PGBE (CAS 5131-66-8), also known as 1-Butoxy-2-propanol or Dowanol PnB, is a P-series glycol ether that delivers EGBE-equivalent solvency (BP 165–175 °C, FP ~61 °C, density 0.901 g/cm³) while being not listed as a US EPA HAP and not classified Repr. 1B/2 under EU CLP. Primary uses: coalescing agent in waterborne architectural and industrial coatings; grease-cutting active in household, institutional, and industrial cleaning products; co-solvent in water-based printing inks; EU 1107/2009-eligible agrochemical co-formulant; pharmaceutical topical co-solvent; personal care solubilizer; reaction solvent and PGBEA precursor in specialty synthesis.
What are the synonyms and CAS number for PGBE?
The PGBE CAS number is 5131-66-8 (EC 225-878-4). Synonyms: 1-Butoxy-2-propanol (IUPAC), Propylene Glycol n-Butyl Ether, Dowanol PnB (Dow commercial grade), 1-Propylene Glycol Monobutyl Ether. Additional synonyms at NCBI PubChem (CID 12837). Distinguish from DPGBE (dipropylene glycol monobutyl ether), PGME (CAS 107-98-2, methyl end-group), or PGPE (propyl end-group) when specifying P-series glycol ethers.
Can PGBE directly replace EGBE in cleaning and coating formulations?
In the majority of industrial and institutional cleaning formulations and waterborne coatings, PGBE can replace EGBE as a near-drop-in substitute. Both share nearly identical boiling points (PGBE 165–175 °C vs EGBE 168–173 °C), identical flash points (~61 °C), identical density (0.901 g/cm³), and full water miscibility - enabling weight-for-weight substitution in most cleaning concentrates with minor fragrance masking and surfactant ratio adjustments. In waterborne coatings, minor co-solvent ratio adjustments and VOC recalculation are typically required. The primary motivation is regulatory: eliminating EGBE's HAP status from US facility inventories (removing potential MACT and NESHAPs obligations under 40 CFR Part 63) and simplifying EU product hazard communications. Sinolook recommends bench-scale trials before full scale-up; qualification samples available.
What is Dowanol PnB and how does Sinolook's PGBE compare?
Dowanol PnB is Dow Chemical's commercial grade of Propylene Glycol Monobutyl Ether (CAS 5131-66-8) - a well-established benchmark product in coatings and cleaning industries. Sinolook's PGBE is manufactured to a specification (purity ≥99.0%, water ≤0.2%, color ≤10 Pt-Co) consistent with Dowanol PnB's primary industrial applications. Customers transitioning from Dowanol PnB to Sinolook PGBE should request a Certificate of Analysis for direct comparison and, if required, conduct qualification testing in their specific formulation system. Sinolook provides samples for this purpose; our technical team assists with qualification protocols and EGBE-to-PGBE transition documentation.
What is PGBEA and does Sinolook supply it?
Propylene Glycol Monobutyl Ether Acetate (PGBEA, CAS 131737-44-5) is produced by esterification of PGBE with acetic acid - a slower-evaporating, less polar companion retarder for high-performance automotive refinishing and industrial maintenance coatings requiring maximum open time and gloss. PGBEA shares PGBE's non-HAP status, making the PGBE + PGBEA solvent pair a fully non-HAP solution for premium coating systems currently using the EGBE + EGBEA combination. Contact sales@sinolookchem.com for PGBEA availability and combined PGBE + PGBEA quotation.
