Four Step VOC Limits for US Cleaners: EPA Table 1 & CARB Reactivity

October 4, 2026
Four Step VOC Limits for US Cleaners: EPA Table 1 & CARB Reactivity

Federal VOC limits for cleaning products live in 40 CFR Part 59 Table 1, and California adds its own stricter category rules through CARB's Consumer Products Program. The immediate move for any brand or formulator: classify your product's category and form, calculate the finished-product VOC weight percent excluding packaging, and check both federal and destination-state limits before you manufacture or ship.

TL;DR:

  • Federal VOC limits vary by product category, with general purpose cleaners restricted to 10% VOC by weight and aerosol bathroom cleaners limited to 7%.
  • California's CARB adds stricter rules, including fragrance exemptions and reactivity limits, requiring formulators to adjust formulas based on manufacture date and target market.
  • Proper compliance involves classifying products correctly, accurately calculating VOC content, comparing against both federal and state limits, and maintaining thorough documentation.
  • Using low-vapor-pressure VOCs and replacing solvents with enzyme systems or chelating agents can help meet tight regulations without sacrificing cleaning performance.
  • Noncompliance can lead to regulatory actions such as stop-sales or reformulation orders, making ongoing record-keeping and monitoring essential for market access.

Federal limits: what 40 CFR Part 59 Table 1 actually sets

Part 59 is the EPA's national rule for consumer and commercial product VOC emissions, and Table 1 is where the real numbers live. It assigns a maximum VOC content, expressed as weight percent of the finished product, to dozens of product categories. Miss your category, and you're measuring against the wrong ceiling.

For cleaning products, the table specifies category-specific VOC limits that manufacturers must follow.

  • General purpose cleaners top out at 10% VOC by weight under Table 1.
  • Bathroom and tile cleaners are capped at 7% for aerosol forms and 5% for non-aerosol forms.
  • Glass cleaners allow 12% for aerosols and 8% for other forms, reflecting the solvent load aerosol propellants typically require.
  • Floor products and other specialty cleaners each carry their own category-specific ceiling within the same table.

The aerosol versus non-aerosol split shows up again and again, because propellant systems often need more VOC-active solvent to perform. Part 59 Subpart C also ties compliance to manufacture or import date: a product made before an amendment's effective date may be governed by the prior limit, so knowing your production date matters as much as knowing your formula. Get the category wrong and the rest of your compliance math is built on sand.

California's CARB rules add fragrance exemptions and reactivity limits

California doesn't just borrow the federal numbers and tighten them. The CARB Consumer Products Regulation layers in category limits, reactivity controls through Maximum Incremental Reactivity, and outright prohibitions on certain toxic air contaminants and high-global-warming-potential compounds. A product can clear the federal weight-percent threshold and still fail in California on reactivity or restricted-ingredient grounds.

Fragrance is where this gets genuinely tricky. CARB's own regulatory text, reflected in 17 CCR 94510, grants combined fragrance and monoterpene allowances for some non-aerosol general-purpose cleaners and degreasers, but those allowances shrink on phased effective dates. A formula that relies on a pre-2031 allowance to hit its scent profile may need rebalancing once the later, reduced allowance takes effect.

  • CARB references a combined fragrance and monoterpene allowance (an example cited at 0.25%) that applies differently depending on manufacture date, per CARB's program materials.
  • Low-vapor-pressure VOCs carry their own exemption language under the CARB rule text, which changes how you count certain solvents toward your total.

CARB's rules combine mass-based VOC limits with reactivity and toxicity controls, so a single weight-percent number never tells the whole story in California. If a meaningful share of your volume ships into the state, the practical choice is either to formulate every SKU to CARB's tighter standard or to run a California-specific version of your product line.

Build a four-step compliance check before you manufacture

A repeatable workflow beats a one-time check, especially once you're running multiple SKUs across multiple states. Here's the sequence that holds up under audit.

  1. Classify the product by its labeled purpose and physical form. "General purpose cleaner," "glass cleaner," and "bathroom and tile cleaner" are treated as distinct categories with distinct limits, and aerosol versus non-aerosol status changes the ceiling again.
  2. Calculate finished-product VOC percent: total VOC weight divided by finished product weight, excluding packaging, multiplied by 100. Fragrance counts toward this total unless it falls within a specific exemption, and low-vapor-pressure VOCs may be excluded under CARB's LVP-VOC provisions, so confirm which solvents and scent components actually count before you run the math.
  3. Compare your result against both the federal Table 1 limit for your category and any stricter destination-state or CARB limit, and confirm which manufacture-date rule applies to your production run.
  4. Retain the paperwork: supplier material declarations, third-party test reports, batch records, and the label language tying a specific VOC percent claim to a specific lot.

Pro Tip: Keep a documented chain of custody from raw material declaration through finished-batch test report. If a regulator ever questions a VOC claim, the paper trail is what resolves it, not a reformulated promise.

Brands reformulating to hit a lower ceiling often start by swapping solvent systems rather than cutting fragrance load outright. Our guide to low-odor solvent alternatives walks through some of those substitution options for formulators working against a tightening limit.

Testing, labeling, and the paperwork regulators expect

VOC content is typically measured using CARB Method 310 or the test methods referenced in Part 59. Regulators expect a test report tied to a specific batch, not a general formulation estimate.

  • VOC percent statements that match the tested batch, not a theoretical formula target.
  • Manufacture or batch dates that establish which rule version applies.
  • Supplier material safety declarations for every raw material that contributes VOC weight.
  • Signed test certificates from the lab that ran the analysis.

Part 59 also includes innovative-product and variance provisions, which let a manufacturer petition for temporary relief when a reformulation genuinely can't hit the standard limit without losing function, though that route involves a public process and isn't a shortcut for routine noncompliance. Effective dates work in the other direction too: product manufactured before a rule change often remains sellable under the prior limit, which is one more reason the manufacture date belongs in your records next to the VOC percent.

For brands managing multiple production lots, our shelf-life testing protocol for cleaners pairs well with VOC recordkeeping, since both rely on the same lot-based documentation habit.

How SaraWest USA helps brands formulate within these limits

We built SaraWest around real in-house R&D chemists, not a broker network, because compliance work like this needs someone who can adjust a formula the same week a limit changes. Our library of more than 1,200 proprietary formulas across eight industries, including commercial cleaning, gives brands a starting point that's already built around realistic VOC targets, and our pilot-to-scale production means a reformulated batch can move from lab bench to full order without changing manufacturing partners.

When you're ready to talk formulation, come with your destination states, your label claims, and your fragrance percent target. Those details let chemists help determine if a formula meets federal Table 1 standards, whether a California-specific adjustment is needed, and what documentation is generated alongside the batch.

Why VOC limits exist: indoor air quality and health

VOC limits for cleaning products aren't an abstract compliance exercise. Many VOCs emitted during cleaning contribute to indoor air chemistry, and CARB's own research notes that terpenes, common in citrus and pine fragrances, can react indoors and contribute to the formation of secondary pollutants including formaldehyde and fine particles under certain conditions.

That's the reasoning behind CARB's layered approach: a product can meet a flat VOC weight-percent limit and still raise indoor air concerns if its fragrance chemistry is highly reactive. This is also why "VOC-free" on a label isn't a complete claim. A product might be low in total VOC weight while still containing a reactive terpene blend that regulators specifically target through MIR controls rather than the mass-based limit alone.

For buyers and facilities managers choosing cleaning products, the practical signal worth watching is a documented VOC percent plus a clear fragrance ingredient disclosure, rather than a marketing phrase alone. Workers who use cleaning products daily, particularly in enclosed commercial spaces, are the ones most affected by cumulative VOC exposure, which is part of why janitorial and facilities trade groups track these rules so closely.

Formulating for low VOC without losing cleaning power

Cutting VOC content usually means cutting solvent, and solvent is often what carries grease, lifts soil, or helps a surfactant work faster. The formulators who hit tight VOC targets without a performance drop tend to lean on a few repeatable moves.

Water-based surfactant systems with enzyme boosters can replace a portion of the solvent load in general purpose and bathroom cleaners, since enzymes break down organic soil chemically rather than relying on solvent action. Chelating agents help hard-water performance without adding VOC weight, which matters for glass and tile cleaners where mineral spotting is the main complaint. For fragrance, working within CARB's monoterpene allowance rather than defaulting to a high-terpene citrus oil keeps scent appeal while avoiding the reactivity flags discussed above.

Low-vapor-pressure solvents are worth a close look too, since certain LVP-VOCs fall outside the standard VOC count under CARB's rule text, giving formulators room to retain solvency without adding to the regulated total. Our working glass cleaner formulation is one practical example of balancing streak-free performance against a tightened VOC ceiling, and it's a reasonable starting point if you're rebuilding a glass or hard-surface SKU from scratch.

How US limits compare to international VOC rules on imports

Brands importing cleaning products, or exporting US-made formulas abroad, run into a second layer of rules. The European Union regulates VOCs in products through its own chemical and ecolabel frameworks, which differ in structure from the US category-based weight-percent system and generally apply tighter restrictions on specific solvent classes rather than a single aerosol-versus-non-aerosol split. Canada's VOC Concentration Limits for Certain Products Regulations follow a structure closer to the US federal model, with category-based limits, but the category definitions and percentages don't map one-to-one onto Part 59 Table 1.

Comparison of US EU and Canada VOC rules

The practical risk is assuming a formula compliant in one market automatically clears another. A cleaner built to satisfy a European solvent restriction might still exceed a US federal category limit, or vice versa, because the regulatory logic (ingredient-based restriction versus total weight-percent ceiling) isn't the same. Any brand manufacturing for both domestic and international shelves needs to check the destination market's own rule rather than assuming equivalence, and build formulation records that satisfy each market separately.

What enforcement looks like when a cleaner exceeds VOC limits

Noncompliance isn't a theoretical risk. ISSA's industry summary is direct on this point: manufacturers and distributors are prohibited from selling covered products that exceed the VOC limits that apply to them, and that prohibition applies at every point in the supply chain, not just at the manufacturer.

In practice, enforcement tends to start with a records request. CARB and EPA can both ask for the test data and supplier declarations behind a VOC percent claim, and a brand that can't produce them is already in a weaker position regardless of what the actual formula contains. Penalties scale with the violation, and a pattern of noncompliant sales across multiple SKUs or lots draws more scrutiny than a single isolated miss.

The more common real-world consequence, especially for smaller brands, is a stop-sale or reformulation order rather than a headline fine. A distributor pulling a noncompliant SKU from California shelves while a brand reformulates is a quieter but still costly outcome, since it means lost shelf time and a rushed reformulation under deadline pressure. Keeping the documentation described earlier, test reports, batch records, supplier declarations, is what turns a routine regulator inquiry into a quick confirmation instead of a drawn-out investigation.

Keep VOC compliance inside your product lifecycle, not outside it

Regulations shift often enough that compliance can't be a one-time checklist. Assign someone on your team to track CARB and federal amendments, build CARB-level compliance into your base formula when you sell nationally, and keep test records and supplier declarations as a standing part of QA, not a scramble before an audit.

FAQ

What is the standard limit for VOCs?

There is no single standard limit; VOC limits are set per product category under 40 CFR Part 59 Table 1.

What is considered a low-VOC cleaner?

A low-VOC cleaner is one that falls well under its category's ceiling in Table 1, though no single percentage defines "low" across every category. The more precise claim is comparing your tested VOC percent against both the federal limit and any applicable CARB limit for that same category.

Which states have VOC regulations?

Federal limits under Part 59 apply nationwide, and California enforces its own stricter rules through CARB's Consumer Products Regulation. Several other states have adopted VOC rules modeled closely on California's approach, so brands selling nationally should check each destination state's rule rather than assuming the federal limit alone covers them.

What is an acceptable level of VOC?

An acceptable level is whatever falls at or under the limit set for your specific product category, calculated as finished-product VOC weight percent excluding packaging. EPA's Safer Choice guidance notes that certification criteria reference the strictest applicable government standard, often OTC or CARB-based, so "acceptable" in California can mean a lower number than acceptable under the federal baseline alone.
