The 71% of global consumers willing to pay a premium for sustainable products, and the 65% of Gen Z buyers who have switched brands for environmental reasons, no longer accept a recyclable bottle as proof. In 2026 the conversation has moved inside the bottle. Green formulation — the actual chemistry of a product — is now the trust currency in beauty. For cosmetic brands and their procurement teams, this means re-examining every raw material on the INCI list, not just the packaging on the shelf.
From green packaging to green formulation
Five years ago, “sustainable beauty” was a label on the outer carton. Refillable pumps, post-consumer recycled (PCR) plastic, and FSC-certified paper board were the visible proof points. That era is closing.
According to a 2025 Statista market outlook, the global sustainable beauty market is forecast to reach USD 187 billion by 2026, growing at a 6.8% CAGR through 2030 — outpacing the overall cosmetics industry. The same report shows the fastest-growing segment is no longer “natural” finished products, but verified bio-based and biodegradable raw materials inside the formulation. Procurement teams in Vietnam, Indonesia, the Philippines and the UAE are now asking suppliers for ISO 16128 natural-origin-content certificates on the silicone TDS, not just the finished-product safety dossier.
What “green formulation” actually means
The term is increasingly used as a marketing catch-all. From a regulatory and scientific standpoint, a truly green formulation meets four measurable criteria:
- Bio-based feedstock. The carbon in the molecule comes from a renewable biological source (plant, algae, fermentation), certified to ISO 16128 natural origin index or USDA BioPreferred.
- Low-carbon production. Manufacturing emissions disclosed, ideally third-party verified under ISO 14067 or a published product carbon footprint (PCF).
- Biodegradability. The molecule, or its degradation products, reach ≥60% mineralisation within 28 days under OECD 301B or equivalent ready-biodegradability tests.
- Cruelty-free and microplastic-free. No animal testing (in line with EU Cosmetics Regulation 1223/2009), and no intentionally added synthetic polymer microparticles (the EU banned rinse-off synthetic polymer microplastics from 17 October 2023 under Commission Delegated Regulation (EU) 2023/2055; leave-on products follow on 17 October 2029).
Every ingredient should be assessed on those four axes. A silicone that scores 3 out of 4 can be a legitimate “green formulation” choice; a plant oil that scores 1 out of 4 cannot.
The regional regulatory pull
Three regulatory shifts are accelerating the move from marketing claim to chemistry change.
| Region | Regulation | Effective Date | Impact on formulations |
|---|---|---|---|
| EU | (EU) 2023/2055 — synthetic polymer microplastics restriction | Rinse-off: 17 Oct 2023 · Leave-on: 17 Oct 2029 · Other: 17 Oct 2035 | Eliminates plastic microbeads, film-formers with non-biodegradable polymer backbones, and certain acrylate copolymers in rinse-off cosmetics. |
| EU | Regulation (EU) 2025/40 — Packaging and Packaging Waste Regulation (PPWR) | Phased from 12 Feb 2025 to 2030 | Mandatory recyclability, minimum recycled content, and bans on unnecessary outer packaging. |
| China | NMPA “Guidelines for Green Development of the Cosmetics Industry” | Issued 2024, implementation through 2026 | Encourages bio-based, low-carbon, and refillable packaging; emerging eco-label certification. |
| GCC | UAE / Saudi SFDA — voluntary eco-labels, ESMA sustainable product conformity | Rolling, 2024–2027 | Product-level eco-labels being introduced; retailers increasingly request environmental product declarations (EPD). |
| ASEAN | ASEAN Cosmetic Directive — convergence with EU positive lists | Ongoing | Harmonising restricted-substance lists with EU Annexes; member states adopt on staggered timelines. |

For a brand selling across more than one of these regions, the EU 2023/2055 microplastics timeline is now the binding constraint: if your leave-on formulation contains any intentionally added synthetic polymer microparticle, the 17 October 2029 deadline defines your reformulation window.
Four building blocks of a green formulation
A modern sustainable personal-care formulation typically rests on four classes of ingredient — each of which now has eco-credible alternatives to the legacy petroleum-based option.
1. Volatile carriers and sensory solvents. Petroleum-derived light silicones (D4, D5, D6) are being replaced by low-cyclics dimethicone (W201), methyl trimethicone (W202) and caprylyl methicone (W203). These alternatives deliver the same skin feel and volatility profile while staying under the 0.1% residual cyclics threshold set by EU REACH 2024/1328.
2. Plant-derived surfactants. Traditional anionic surfactants (SLS, SLES) carry aquatic toxicity concerns. Alkyl polyglucosides (APG 0810, APG 1214), made from coconut or palm kernel oil and glucose, are readily biodegradable (OECD 301B) and carry a high ISO 16128 natural-origin index.
3. Mild film-formers and conditioning agents. Polyquaternium- and acrylate-based film-formers persist in the environment. Trimethylsiloxysilicate (TMS) resins and cationically modified polysaccharides offer comparable hold with shorter environmental half-lives.
4. Natural emollients and esters. Isoeicosane, isohexadecane and similar branched alkanes are being substituted with plant-derived squalane, esters (e.g. coco-caprylate) and natural triglycerides, all of which meet OECD 301 ready-biodegradability criteria.

FAQ
What counts as a “green formulation” in cosmetics?
There is no single regulated definition, but the most widely accepted framework combines four measurable criteria: bio-based feedstock (ISO 16128 natural-origin index), low-carbon production (ISO 14067 or published PCF), ready biodegradability (OECD 301B or equivalent, ≥60% in 28 days), and freedom from intentionally added synthetic polymer microplastics as restricted under (EU) 2023/2055.
Are silicones really sustainable? They’re synthetic.
Sustainability is a multi-axis question, not a natural-versus-synthetic binary. Silicones built on low-cyclics dimethicone (W201), methyl trimethicone (W202) and caprylyl methicone (W203) deliver the sensory performance of legacy D4/D5/D6 carriers while keeping residual cyclics well below 0.1% and offering efficient use levels that reduce the carbon load of a formulation. They are not “natural” in the ISO 16128 sense, but they are often a more sustainable overall choice than a plant oil that performs poorly in formulation and must be used at much higher levels.
When does the EU microplastics restriction take effect for leave-on products?
Commission Delegated Regulation (EU) 2023/2055, which amends the REACH Annex XVII entry for synthetic polymer microparticles, applies to rinse-off cosmetics from 17 October 2023, to leave-on cosmetics from 17 October 2029, and to all remaining product categories from 17 October 2035. The restriction defines biodegradable polymers in Annex II of the regulation.
