In the world of cosmetics, beauty doesn’t run skin deep. As sustainability becomes increasingly more important, cosmetic brands are being challenged to deliver products that look good and do good. One core place you can make an impact is through packaging – specifically, biodegradable packaging for liquids. From cleansers and serums to shampoos and toners, the industry is undergoing a quiet but powerful revolution.
At Fillcon, we help you stay ahead of the trends with insights, advice, and quality filling for any cosmetic receptacle. Let’s explore the latest trends and technologies in biodegradable packaging for liquid cosmetics, examine the regulatory landscape, and highlight how leading brands are making sustainability a key part of their business strategy.
Why Biodegradable Packaging is Essential for the Future
The global cosmetics industry generates over 120 billion units of packaging every year, much of it made from single-use plastics. A large proportion ends up in landfill or oceans, where it can take centuries to decompose.
Today’s consumers are more environmentally aware than ever. In the UK and beyond, brands are expected to take responsibility for their environmental impact, regardless of where it comes from.
Biodegradable packaging offers a way to dramatically reduce the environmental impact of cosmetic products by ensuring that containers break down into harmless substances, or have a lower impact to begin with.
But liquids pose unique challenges. Packaging needs to be leakproof, protect the product from light and air, and preserve its contents without compromising on sustainability – all while ensuring a safe and sterile product within.
Governments are also taking action. The UK’s Plastic Packaging Tax, introduced in 2022, applies to plastic packaging that doesn’t contain at least 30% recycled content. Meanwhile, the EU’s Green Deal and Circular Economy Action Plan are pushing brands towards more sustainable solutions. Biodegradable packaging, especially for liquids, is fast becoming not just a trend, but a necessity.
Innovative Materials Used in Biodegradable Liquid Packaging
Biodegradable packaging materials have come a long way in a short time. Early options often struggled with durability and shelf life – especially for liquids. But today’s materials are more advanced, combining environmental benefits with the performance brands need.
- Plant-Based Polymers (Bioplastics)
One of the most exciting developments is the rise of bioplastics made from renewable sources like corn starch, sugarcane and cellulose. These materials are biodegradable under industrial composting conditions and can mimic the appearance and function of conventional plastics. PLA, for instance, is already being used in flexible tubes and bottles for lotions and serums.
- Compostable Films
Compostable films are thin, biodegradable layers that provide barrier protection for sachets and sample packaging. Derived from starches or cellulose, these films offer moisture and oxygen resistance while breaking down in composting conditions. They’re increasingly used for single-use products like face masks and sample sachets – traditionally some of the least sustainable packaging in the industry.
- Water-Soluble Materials
Innovations in water-soluble films are opening up new possibilities for packaging products like shampoos, body washes, and hand soaps. These materials dissolve in water and leave no microplastic residue, making them ideal for single-dose packaging or refills.
- Mushroom and Seaweed-Based Packaging
Yes, you read that right! Mycelium (the root system of mushrooms) and seaweed extracts like agar and alginate are being explored for biodegradable packaging. These natural materials are renewable, compostable, and can even provide nutrients to the soil as they break down. While not yet mainstream, they offer intriguing possibilities for outer packaging or even caps and lids… and at Fillcon, we can fill any receptacle you like, regardless of what it’s made from!
- Recyclable Polypropylene Sachets
Plastics are often looked down on when trying to improve recyclability, but they’re actually a really good way of lowering your environmental impact! They’re flexible, meaning more can be shipped at once. They’re lightweight, cutting the carbon for transportation and storage. They’re thin, meaning more of the space and energy is used for your actual product. And they’re durable, meaning less lost product and a greater overall efficiency!

How Brands Are Adopting Eco-Friendly Packaging Solutions
Several forward-thinking brands are already leading the way with biodegradable packaging for liquids, proving that it’s both possible and commercially viable.
Lush
The UK-based cosmetics retailer has long been a pioneer in sustainable packaging. While famous for its ‘naked’ (packaging-free) products, Lush has also experimented with biodegradable containers and compostable alternatives for liquid products such as shower gels and conditioners.
Garnier
As part of its Green Beauty initiative, Garnier has begun trialling biodegradable sachets and refill stations to reduce the need for single-use plastic in shampoo and conditioner packaging. They’ve also committed to making all packaging either recyclable, reusable or compostable by 2025.
Beauty Kitchen
This UK indie brand is using compostable packaging for some of its liquid products and promotes a ‘Return, Refill, Repeat’ scheme to encourage circular use of containers. It’s a great example of blending biodegradable innovation with a wider sustainability model.
Notpla
Though not a cosmetics brand itself, Notpla – a London-based start-up – has developed seaweed-based biodegradable packaging, including sachets for liquids. While currently focused on the food and beverage industry, the material has potential for crossover into personal care products.

What’s Next for Biodegradable Packaging?
The future looks promising – but not without challenges. While biodegradable materials are improving rapidly, there are still limitations around cost, availability, and compatibility with existing manufacturing systems. In many cases, the composting infrastructure needed to break down these materials properly is still limited.
That said, consumer demand continues to rise, and legislation is pushing the industry forward. The most successful brands will be those that take a proactive approach, investing in research, trialling new materials, and collaborating with packaging innovators.
There’s also increasing interest in hybrid solutions – for instance, using biodegradable sachets as part of a refill system, or combining compostable elements with recyclable parts to create more flexible, lower-impact designs.
