A practical checklist for cosmetics and personal-care manufacturers and their suppliers preparing for a retailer's restricted-substance list or clean program. It covers how brands cascade RSL requirements down to contract manufacturers and up to raw-material suppliers, how to map each restricted-substance requirement to the supplier evidence that proves it, and how to keep that evidence current between retailer review windows.
Operational guide, not legal advice
Treat the RSL as a living evidence requirement, not a one-time form
The strongest brands and CMOs can answer three questions fast: which substances the retailer restricts, which supplier documents prove each product complies, and who approved the answer. Valent turns those answers into a review-ready file instead of a scramble every time a retailer opens a window.
Why this matters
A retailer can hold a product at onboarding or pull it from a shelf reset when the restricted-substance evidence behind it is missing, stale, or unsigned. The durable work is not answering one RSL questionnaire; it is keeping formula disclosure, supplier declarations, and test data tied to each SKU as formulas, fragrances, and suppliers change.
A retailer publishes an updated restricted-substance list, but no one re-checks in-market formulas against the new version.
A CMO confirms compliance, but the raw-material supplier declarations behind the claim were never collected or have expired.
Formula and INCI disclosure lives with the fragrance house or contract manufacturer, so the brand cannot show what is actually in the product.
Test reports and declarations exist, but they cannot be tied to the specific formula version, lot, or SKU the retailer is asking about.
How the compliance layers stack up
Federal (US)
MoCRA sets federal cosmetics obligations for facility registration, product listing, and safety substantiation. It does not replace a retailer's restricted-substance list, and retailers often restrict more than federal law requires.
State (US)
State laws such as California's Proposition 65 and a growing set of state ingredient restrictions require warnings or ban specific substances. Retailers frequently fold these expectations into their own RSL.
International
The EU Cosmetic Products Regulation restricts or prohibits substances through its annexes and requires ingredient and fragrance-allergen disclosure. Brands selling across regions usually reconcile to the strictest requirement per ingredient.
Retailer RSL / clean program
A retailer's restricted-substance list or clean standard is a private, contractual requirement. It can restrict ingredient classes and demand supplier evidence beyond any single regulation, and it changes on the retailer's own schedule.
Turn the RSL into work your teams can run
Use this sequence to move from a retailer's list to a defensible evidence file across the brand, the contract manufacturer, and the raw-material supplier chain.
01
Read the retailer's RSL against the product
Start with the current version of the retailer's restricted-substance list or clean standard and compare it to each product's full formula. Note every restricted substance, ingredient class, and disclosure requirement that could touch the SKU.

02
Cascade requirements to the CMO and suppliers
Brands rarely hold every ingredient detail themselves. Push the RSL down to the contract manufacturer that makes the product and up to the raw-material and fragrance suppliers that know what goes into each input.

03
Map each RSL requirement to supplier evidence
A restricted-substance claim is only as strong as the document behind it. Tie each requirement to the specific evidence that proves it, at the formula-version and lot level.

04
Review and approve before answering the retailer
A complete file still needs a decision. Confirm the evidence matches the in-market formula, that dates are still valid, and that a reviewer has approved the response before it leaves the building.

05
Keep the file current between review windows
Formulas, fragrances, and suppliers change on their own schedule, and retailers update their lists on theirs. Set triggers so a reformulation, supplier swap, or RSL revision creates a review task instead of a silent gap.

What a retailer RSL or clean program actually is
A retailer restricted-substance list, sometimes branded as a clean program, is the retailer's own list of ingredients it restricts, caps, or bans in the products it carries. It is a condition of doing business, enforced through onboarding questionnaires, contracts, and periodic reviews rather than by a regulator.
Restricted, capped, and prohibited ingredient classes
Required supplier evidence and disclosures
Onboarding, reset, and renewal review points
Consequences for non-compliance, from holds to delisting
The supplier evidence that backs each requirement
Most RSL answers depend on documents the brand does not generate itself. Standardize the evidence set so a reviewer can move from a restricted substance to the proof for a specific formula and lot.
SDS with current version and effective date
Formula and INCI disclosure at the ingredient level
Restricted-substance declarations and supplier attestations
COA, test data, and fragrance-allergen documentation
Keeping evidence current between review windows
Retailer reviews are periodic, but the risk is continuous. Evidence goes stale when a supplier reformulates, a declaration expires, or the retailer revises its list without anyone re-screening the products already on the shelf.

Checklist
Close the evidence gaps before the retailer opens a review window
Use these checks to keep restricted-substance evidence complete, current, and traceable between onboarding and each shelf reset.
01
List every restricted substance, ingredient class, and disclosure the retailer's current RSL requires.
02
Cascade each requirement to the CMO and to the raw-material and fragrance suppliers that hold the answer.
03
Map each requirement to its supplier evidence: SDS, formula/INCI disclosure, restricted-substance declarations, COA or test data, and fragrance-allergen data.
04
Confirm the evidence matches the in-market formula version and that dates are valid, then route the response through an approver.
05
Set change and RSL-version triggers so evidence stays current between onboarding and the next shelf reset.
