If you private-label cleaning products, air fresheners, or automotive care products sourced from China to sell in California, there’s a disclosure law that’s been quietly in effect for several years — and its definition of “manufacturer” is broader than most private-label sellers assume. This piece covers what it actually requires, an honest look at how it’s enforced, and why private-label sellers specifically need to pay attention.
1. What this law is, and how long it’s actually been in effect
The California Cleaning Product Right to Know Act of 2017 (Senate Bill 258) was the first US state law requiring public disclosure of ingredients in cleaning products. Its two compliance deadlines have both already passed: online/website ingredient disclosure became mandatory January 1, 2020, and on-package label disclosure became mandatory January 1, 2021. This isn’t a new or emerging requirement — it’s been a real, active obligation for several years, and if you’re currently selling covered products in California without having addressed it, you’re already out of compliance, not approaching a future deadline.
2. What products are covered
The law applies to “designated products” — air care products (air fresheners), automotive cleaning products and polishes, general cleaning products, and polishes or floor maintenance products intended for janitorial, domestic, or institutional use. Food, drugs, cosmetics, products regulated under the federal pesticide law (FIFRA), and certain industrial-process-only chemicals are excluded.
3. The specific disclosure requirements
- Every intentionally added ingredient must be listed in descending order by weight (with an exception for confidential business information and fragrance ingredients specifically, which follow a separate rule).
- Nonfunctional constituents present at 0.01% (100 ppm) or higher must be disclosed.
- Fragrance allergens present at 0.01% (100 ppm) or higher that appear on Annex III of the EU Cosmetics Regulation (No. 1223/2009) must be flagged — a notable detail, since California’s law directly references an EU regulatory list as its trigger threshold, rather than building an entirely separate list from scratch.
- 1,4-dioxane specifically must be disclosed at just 0.001% (10 ppm) or higher — a notably stricter threshold than the general 0.01% rule, reflecting this contaminant’s specific health concern.
- Any ingredient appearing on one of 22-23 designated regulatory lists (including California’s Proposition 65 list) must be disclosed along with its functional purpose in the product.
- Ingredient names must follow a specific nomenclature hierarchy: the Household and Commercial Products Association’s Consumer Product Ingredients Dictionary, then INCI naming, then IUPAC chemical nomenclature, in that priority order.
4. The point private-label sellers specifically need to know
This is the detail most relevant to anyone sourcing private-label products from China: the Act’s definition of “manufacturer” explicitly includes distributors and retailers of private-label products — not just the original factory that formulated the product. If you’re putting your own brand on a cleaning product manufactured in China and selling it in California, you are directly responsible for this disclosure obligation, regardless of whether your Chinese supplier has already published anything themselves. This ties directly into the broader private-label liability pattern — as covered in our guide on OEM, ODM, and private label distinctions, putting your own brand on a factory’s product generally means taking on compliance responsibilities the original manufacturer might otherwise carry.
5. An honest caveat: this law’s enforcement mechanism is notably weaker than others we’ve covered
This is worth stating plainly, because it changes the real risk calculus compared to something like California’s Proposition 65 (which we’ve covered separately, and which carries real financial penalties enforced through both government action and private litigation): legal trackers monitoring this Act note explicitly that it “does not impose penalties for violations, nor does it specify a mechanism for enforcement.” This doesn’t mean the disclosure obligation isn’t real or that you should ignore it — it’s a genuine legal requirement — but the practical enforcement risk profile here is meaningfully different from a law with an active penalty structure and litigation history behind it. Treat this as a real compliance obligation worth addressing properly, not as a source of the kind of acute legal exposure some other California consumer laws carry.
6. A secondary compliance point worth knowing
The Act’s reach extends slightly beyond manufacturers and sellers: California employers who are required to maintain a Safety Data Sheet (SDS) for a covered product must also make the Act’s required “printable” ingredient information available to employees — relevant if you’re supplying covered products into a commercial or institutional setting in California, not just direct-to-consumer retail.
7. What to do before you sell in California
- Confirm your product falls under a “designated product” category — air care, automotive, general cleaning, or polish/floor maintenance products intended for janitorial or domestic use.
- If you’re selling under your own brand, treat yourself as the responsible “manufacturer” for this obligation — don’t assume your Chinese supplier’s compliance (if any) covers your private-label version.
- Request a full ingredient list from your supplier, including nonfunctional constituents and any trace-level contaminants like 1,4-dioxane, specifically framed around this Act’s thresholds rather than a generic safety data sheet alone.
- Build the required website disclosure and label language before you launch, rather than treating it as a follow-up task — both deadlines under this law passed years ago, so there’s no grace period to lean on.
The bottom line
California’s Cleaning Product Right to Know Act has been a real, active disclosure requirement since 2020-2021, and its definition of “manufacturer” reaches private-label sellers directly — meaning if you’re putting your own brand on a China-sourced cleaning product sold in California, this obligation is yours, not just your supplier’s. The enforcement mechanism is notably softer than laws like Prop 65, but that’s a reason to handle it properly and quietly, not a reason to skip it.
