If you’re buying industrial and institutional cleaning products for operations in California, New Jersey, Oregon, or any state whose environmental agency is watching those states for a model to copy, your product formulations are being affected right now. Some products have already been reformulated. Others have been pulled from shelves in regulated states. And some distributors are selling the same SKU in two different formulations — one for California, one for everyone else — without making that obvious on the label.
This guide is for procurement officers and facility managers who need to understand what’s changing, which product categories are most affected, and what questions to ask suppliers before a purchase or a multi-year contract. It does not require a chemistry degree. It does require about 20 minutes of your time to avoid a compliance problem or a product performance surprise.
The most common failure mode this guide prevents: a BSC or FM buys a “VOC-compliant” product from a national distributor, deploys it across all facilities, then discovers it’s compliant in 38 states but not in California or New Jersey — where half their facilities operate.
What VOC Means in Cleaning Chemistry
VOC stands for volatile organic compound. In the context of cleaning product regulation, the working definition comes from EPA and state air quality agencies, not from chemistry textbooks. The regulatory definition of VOC excludes certain compounds (like acetone, which is technically organic and volatile but excluded because it has low ozone-forming potential) while capturing others that do react in the atmosphere to form ground-level ozone — smog.
Ground-level ozone is not the beneficial kind in the upper atmosphere. It’s an air pollutant that irritates the lungs, triggers asthma, reduces agricultural yields, and contributes to the brown haze visible over industrial corridors. States in non-attainment areas for ozone under the federal Clean Air Act have strong legal incentive to reduce VOC emissions from every source they can regulate — including cleaning products.
The organic solvents used in many degreasers — glycol ethers, petroleum naphtha, d-limonene, alcohol ethers — are typically regulated VOCs. When you spray a solvent degreaser in a building, some of those compounds evaporate into the air. In a well-ventilated industrial space, this is primarily a worker exposure issue (handled under OSHA standards). But in aggregate, cleaning product emissions contribute measurably to regional ozone formation, which is why air quality districts regulate them.
The GHS SDS and VOC Content
Under the GHS 16-section SDS format (aligned with OSHA’s Hazard Communication Standard, 29 CFR 1910.1200, final rule updated May 2024), VOC content may appear in Section 9 (Physical and Chemical Properties). Not all SDS documents report VOC content in a standardized way — some report it as a weight percentage, others in grams per liter, and some not at all if the manufacturer doesn’t sell in regulated states. If VOC content isn’t in the SDS, ask the manufacturer directly. Get it in writing.
The CARB and SCAQMD Rules: The Regulatory Model Everyone Else Copies
The California Air Resources Board (CARB) Consumer Products regulation sets VOC limits by product category — expressed in grams of VOC per liter of product (excluding water and exempt compounds). It covers a wide range of products including general purpose cleaners, degreasers, glass cleaners, floor strippers, disinfectants, and aerosol products. California’s limits are generally the lowest in the country, and they’ve been tightening over successive regulatory cycles.
Within California, the South Coast Air Quality Management District (SCAQMD) adds another layer. SCAQMD Rule 1171 specifically governs solvent cleaning operations in the South Coast Air Basin (the Los Angeles Basin and parts of surrounding counties). Rule 1171 sets VOC limits on cleaning solvents used in industrial and commercial operations, with different limits for different use categories — general solvent cleaning, hand cleaning, electronic cleaning, aerosol products, and others. Facilities in the South Coast Air Basin that use solvents for parts cleaning, equipment wiping, or spray degreasing need to verify Rule 1171 compliance, not just the statewide CARB consumer products limits.
These two frameworks — CARB consumer products limits and SCAQMD Rule 1171 — are the most widely watched benchmarks in the country. When New Jersey or Oregon writes VOC rules for cleaning products, they typically reference CARB as the basis. When chemical suppliers reformulate for VOC compliance, they typically formulate to meet California first.
Why Exempt Compounds Matter
Not all organic solvents count toward the VOC limit under the regulatory definition. Certain compounds are “exempt” because they have negligible ozone-forming potential. Acetone is the most commonly used exempt compound in cleaning products. Some formulations have shifted toward acetone or other exempt solvents specifically to reduce their regulatory VOC number while maintaining solvent cleaning performance. This is legal and often effective — but exempt doesn’t mean hazard-free. Check the SDS for the applicable health hazard and flammability data on any substituted compound. Acetone is highly flammable (flash point approximately 0°F / -18°C) and should be treated accordingly.
New Jersey: N.J.A.C. 7:27-24 and 2026 Phased Compliance
New Jersey adopted amendments to N.J.A.C. 7:27-24 — the state’s consumer products VOC rule — bringing product category limits closer to CARB’s framework. Multiple cleaning product categories are affected, with phased compliance dates that concentrate in 2026. The NJDEP has maintained a rulemaking record and stakeholder process; the compliance dates and specific category limits are documented in the published rule amendments.
For buyers, the practical implication: if you’re purchasing products for New Jersey facilities on a multi-year contract, confirm with your supplier that the formulation will meet N.J.A.C. 7:27-24 limits through the contract period, including phased compliance dates where they apply. Get a written product compliance attestation. A supplier who says “it’s fine” verbally but won’t put a compliance attestation in writing is a risk.
New Jersey’s rule generally covers the same product categories as CARB: general purpose cleaners, degreasers, glass cleaners, bathroom and tile cleaners, floor strippers, floor wax strippers, aerosol products, and others. The specific gram-per-liter limits differ by category; because these limits are subject to revision, buyers should verify current limits directly with NJDEP or request the supplier’s current compliance documentation rather than relying on limits cited in a secondary source.
Oregon DEQ: Active Rulemaking
Oregon DEQ has been developing a consumer products VOC rule modeled on CARB. As of the time of writing, Oregon’s rulemaking process has been in an active phase, with a framework substantially based on California’s approach. The specific effective dates and final category limits for Oregon should be verified directly with Oregon DEQ, as the rulemaking timeline can shift. If you operate facilities in Oregon and your current product portfolio is California-compliant, it is likely to be Oregon-compliant once the rule is finalized — but confirm, don’t assume.
How State VOC Rules Affect National Product Formulations
This is the part that affects buyers in states with no VOC rules for cleaning products: because California is the largest U.S. market, and because the cost of maintaining two separate product lines (one for California, one for everyone else) is substantial, most major cleaning chemical manufacturers have reformulated their high-volume products to meet California limits across all markets. This means buyers in Ohio or Texas may already be receiving reformulated products without knowing it.
The reformulation effect is not always benign for performance. Some traditional heavy-duty solvent degreasers that worked well on a specific soil profile have been reformulated to lower VOC content, and some buyers have found the reformulated version meaningfully less effective on the same soils. If you’ve noticed a performance change in a product you’ve used for years without a price change or obvious label change, VOC reformulation is a plausible explanation. Ask the manufacturer directly.
TSCA Section 6: TCE Phase-Out
EPA’s December 2024 final rule under TSCA Section 6 on trichloroethylene (TCE) is a related but distinct regulatory action. TCE has been a workhorse solvent for vapor degreasing — particularly in metal fabrication, electronics, and aerospace parts cleaning. The final rule phases out most commercial uses of TCE, including vapor degreasing, under a phased timeline beginning 2025. This is not a VOC rule; it’s a chemical hazard rule. But the operational impact for machine shops and manufacturing facilities running TCE-based vapor degreasers is immediate: those systems need to transition to alternative chemistries. The alternatives most commonly evaluated are n-propyl bromide (itself facing scrutiny), modified alcohol blends, aqueous cleaning systems, or advanced aqueous alternatives. If your facility still uses TCE-based vapor degreasing, contact your chemical supplier and your environmental compliance officer immediately.
Product Categories Most Affected by VOC Limits
Not all cleaning products are equally regulated. The table below identifies the major categories under active VOC regulation in California and the states adopting similar frameworks.
| Product Category | VOC Regulation Status | Key Considerations |
|---|---|---|
| General purpose cleaners | Regulated under CARB; NJ 2026 phased dates | Typically lower starting VOC content; many compliant; check concentrate vs. RTU separately |
| Degreasers (industrial/commercial) | Regulated under CARB consumer products rule; SCAQMD Rule 1171 for solvent degreasing operations | Highest VOC exposure category; many traditional formulations affected; solvent degreasers most impacted |
| Glass cleaners | Regulated under CARB | Alcohol-content products affected; most major brands reformulated |
| Floor strippers | Regulated under CARB and NJ rule | High-VOC traditional strippers reformulated; low-VOC alternatives widely available |
| Disinfectants and sanitizers | Generally lower VOC; EPA FIFRA governs efficacy claims separately | Some alcohol-based disinfectants (especially aerosols) carry VOC load; check for aerosol-specific limits |
| Aerosol products | Subject to separate aerosol-specific limits in most frameworks | Often the most restrictive category; VOC limits for aerosol degreasers are frequently much lower than equivalent liquid products |
| Bathroom/restroom cleaners | Regulated | Acid-based products generally low-VOC; surfactant-heavy products typically compliant |
| Carpet cleaners | Regulated under CARB | Solvent-based carpet spotters most affected |

What to Ask Your Supplier: Checklist
Before purchasing or renewing a contract for any degreaser or cleaning product in regulated or potentially regulated states, go through these questions with your supplier. Ask for written responses where noted.
SUPPLIER VOC COMPLIANCE CHECKLIST (8 QUESTIONS)
□ 1. VOC CONTENT BY WEIGHT AND BY GRAMS PER LITER
"What is the VOC content of this product as formulated,
expressed in grams of VOC per liter (excluding water and
exempt compounds per EPA method 24 or equivalent)?"
Request written documentation. Don't accept verbal-only.
□ 2. CALIFORNIA CARB COMPLIANCE
"Is this product formulated to meet the current CARB consumer
products VOC limits for its product category? Which category
does CARB classify this product under?"
□ 3. NEW JERSEY N.J.A.C. 7:27-24 COMPLIANCE
"Is this product compliant with the New Jersey consumer products
VOC rule amendments, including phased 2026 compliance dates?"
Request a written compliance attestation if your facilities are in NJ.
□ 4. OREGON DEQ STATUS
"When Oregon DEQ finalizes its consumer products VOC rule,
is this product expected to comply? Can you provide the
current VOC content documentation now?"
□ 5. REFORMULATION HISTORY
"Has this product been reformulated for VOC compliance in the
last 24 months? If so, what changed and how has performance been
validated on [your specific soil profile]?"
□ 6. SCAQMD RULE 1171 (for South Coast Basin operations)
"If we are using this product for solvent cleaning operations
in the SCAQMD jurisdiction, does it comply with Rule 1171
limits for [general solvent cleaning / hand wipe / other]?"
□ 7. EXEMPT COMPOUND SUBSTITUTIONS
"Does this formulation use exempt compounds (e.g., acetone,
methyl acetate, parachlorobenzotrifluoride, HFOs) to achieve
low regulatory VOC content? If so, what are the flash point and
health hazard implications of those compounds?"
□ 8. TCE AND REGULATED SOLVENT STATUS
"Does this product contain trichloroethylene (TCE), methylene
chloride (DCM), or perchloroethylene (PERC)? These are subject
to active EPA TSCA regulatory action."
What to Audit in Your Current Inventory
If you haven’t audited your cleaning chemical inventory for VOC compliance, here’s a practical approach:
Step 1: Pull the SDS for every cleaning product you’re currently using. Look at Section 9 (Physical and Chemical Properties) for VOC content. Note any products that don’t report it — those need a follow-up call to the manufacturer.
Step 2: Identify which products are degreasers and which are aerosols. These are typically the highest-VOC categories and the first places regulators focus.
Step 3: Map your facilities to regulated jurisdictions. California (including SCAQMD region), New Jersey, and Oregon require different compliance standards. If you’re operating nationally, your California facilities are the most restrictive.
Step 4: Flag products without VOC documentation. Any product without a clear VOC grams-per-liter figure on the SDS or in a manufacturer compliance document is a gap. Close it before your compliance date.
Step 5: Check for TCE. Run a search on your SDS library for trichloroethylene or TCE in Section 3 (Composition). Any product containing TCE for a commercial cleaning use needs to be on your transition plan given the EPA TSCA Section 6 phase-out.
Step 6: Set a recurring calendar reminder. VOC rules are not static. The CARB consumer products rule has been updated on multiple cycles. NJ and Oregon are in active adoption phases. Schedule a supplier review every 12 months.
Common Mistakes
Assuming “VOC compliant” means compliant everywhere. A product labeled VOC compliant was formulated to meet a specific rule in a specific jurisdiction at a specific point in time. Ask which rule. California? NJ? The federal EPA definition? These are not the same.
Conflating the OSHA airborne exposure limits with the environmental VOC limits. OSHA’s permissible exposure limits (PELs) and ACGIH TLVs govern worker exposure in the workplace. State VOC rules govern emissions contributions to ambient air quality. A product can comply with one framework without complying with the other.
Ignoring aerosols. Aerosol products frequently carry higher VOC loads than their liquid equivalents, and state rules often set stricter limits for aerosol formats. A liquid degreaser that’s California-compliant may have an aerosol version that’s not.
Not requesting written compliance attestations before contract lock-in. If you’re signing a 2-year supply contract for a cleaning chemical in a regulated state, get a written statement from the manufacturer that the product will remain compliant through the contract period, or include a right-to-substitute clause if the formulation changes for compliance reasons.
Overlooking reformulation performance changes. When a supplier reformulates a solvent-heavy degreaser to meet VOC limits, the cleaning performance on heavy petroleum soils may decrease. Validate the reformulated product on your actual soils before committing to a full deployment. Run a side-by-side trial if the soil load is critical.
