Sustainable Claims on Cosmetic Packaging: What You Can Legally Say and How to Substantiate It

Sustainable claims must be truthful and substantiated. In the US follow the FTC Green Guides; internationally follow ISO 14021; in the EU follow the Green Claims Directive. Make specific claims you can prove with a certificate, and keep that evidence on file for the life of the product.

Environmental marketing is regulated because vague claims mislead buyers and disadvantage honest brands. The core principle is the same everywhere: a claim must be clear, specific to what you actually do, and supported by competent evidence at the time you make it. 'Eco-friendly' with no qualifier is the classic forbidden claim because nothing is friendly to everything. 'Recyclable where facilities exist' with a resin ID and a documented collection rate is defensible. The difference is evidence. This guide maps the main rules and the documents that back a claim.

The Three Rule Sets You Must Know

In the United States, the Federal Trade Commission's Green Guides tell brands how to avoid deceptive environmental claims. They are guidance, not regulations, but the FTC enforces them under its general anti-deception authority. They were last revised in 2012 and are under review, so watch for updates on carbon-offset and 'net zero' language.

Internationally, ISO 14021 sets the vocabulary for self-declared environmental claims. It defines what 'recyclable', 'recycled content' and 'recoverable' mean and requires each claim to be verifiable and not misleading. Many national laws and retailer codes reference it directly. Our resin ID guide shows the codes the claim depends on.

In the European Union, the Green Claims Directive plus the 2024 Empowering Consumers rules require explicit environmental claims to be pre-substantiated by a verified method and based on the product's life cycle. Generic 'environmentally friendly' claims are banned unless proven. A claim valid in one region can still fail in another, so define the market before you print the word.

The 'Recyclable' Claim

'Recyclable' is safe only when the bottle is made of a commonly recycled resin and collection exists where you sell. PET (#1) and HDPE (#2) are widely accepted; PETG, while recyclable in theory, is less commonly collected. State the resin and the code, and qualify the claim with 'where facilities exist' where appropriate.

Back it with the resin identification code and, for stronger claims, a documented reprocessing rate or a statement from your recycler. An unqualified '100% recyclable' on a pump bottle is risky because the pump and spring are often not recycled with the bottle. Claim the bottle, not the assembly, unless the closure is proven too. Our EPR guide covers the producer-responsibility side.

Avoid 'made from recyclable material' when you mean the finished bottle can be recycled. The two are different claims with different proof. Say what you mean, and keep the evidence that supports the exact wording you chose.

The 'Recycled Content' Claim

'Recycled content' must state the percentage and whether it is pre-consumer or post-consumer. Post-consumer content (PCR) is the stronger, more credible claim. The percentage needs a basis: a mass-balance certificate for a mixed stream, or a certificate of analysis for a segregated one.

Pre-consumer (factory scrap) content is legitimate but weaker in the market's eye, and some rules treat it differently. Label it honestly. A '30% recycled' claim with no qualifier invites challenge; '30% post-consumer recycled (PCR)' with an ISCC PLUS or chain-of-custody certificate is defensible. Our PCR vs virgin guide explains the documentation.

Match the claim to the resin grade. PCR PET is common and food-contact approved at verified percentages; PCR in HDPE and PETG follows the same logic but with different supply maturity. Keep the supplier's certificate with the batch record so the claim travels with the product.

The 'Compostable' and 'Biodegradable' Claims

'Compostable' is the strongest and the riskiest claim. It requires the item to break down in a defined composting environment within a set time, usually certified to EN 13432 (EU) or ASTM D6400 (US). A home-compostable claim needs a different, stricter standard. Without the certificate, do not use the word.

'Biodegradable' alone is broadly discouraged because everything biodegrades eventually, and the location and time matter. The FTC warns against unqualified biodegradable claims. If you use it, state the environment (industrial compost, soil, marine) and the time frame, each backed by test data. Our biodegradable resin guide covers which resins actually qualify.

Most cosmetic bottles in PET, HDPE and PETG are recyclable, not compostable. Claiming compostable for a standard PET bottle is a clear greenwashing risk. Reserve compostable language for resins and formats that genuinely certify to a standard.

The 'Bio-Based' Claim

'Bio-based' means the carbon comes partly or wholly from plants, not that the item is biodegradable. State the percentage and the certification (ISCC PLUS or RSB for mass-balance bio-PET). Bio-based and recyclable are independent properties; a bottle can be both, and the claims should say so separately.

Do not imply bio-based means lower environmental impact without a life-cycle view. A plant-derived resin shipped halfway around the world may or may not beat fossil resin on footprint; the claim should rest on a verified comparison, not a slogan. Our bio-based resins guide explains the trade-offs and the certificates.

The safest bio-based claim is narrow and documented: '30% plant-based carbon (ISCC PLUS certified)'. It is specific, verifiable and defensible in any of the three rule sets above. Broader claims need broader proof.

What to Keep on File

For every environmental claim, keep the evidence that supported it at the time you made it, and keep it for the product's commercial life plus a buffer. That means resin ID records, PCR or bio-based certificates, compostability test reports, and any life-cycle or footprint study you cited. Regulators and retailers ask for these on demand.

Also document the claim wording and the market it applied to, so a bottle sold in the EU is not challenged under a US-only assumption or vice versa. A claim that is fine in one region can fail in another; the file should show you knew the difference.

At ShiJin we mold PET, HDPE and PETG from our 1,000+ open mold library with MOQ 5,000 units and 15-25 day lead times. We supply food-contact and cosmetic-contact statements and, on request, PCR content with ISCC PLUS or chain-of-custody certificates and bio-based carbon percentages with mass-balance certification. Tell us the claim you intend to make and the market, and we will supply the resin and the certificate that substantiates it.
