A Partnership for Sustainability

At Stream2Sea, our commitment to environmental stewardship has always been unwavering. That’s why we’re thrilled to announce our collaboration with 4ocean, a trailblazer in ocean cleanup efforts. Together, we have created a sunscreen balm that not only meets rigorous safety standards but also champions sustainability at every turn. Packaged in our first-ever recyclable and reusable metal container, this SPF 40 balm is a testament to our dedication to reducing plastic waste. Its sheer application and biodegradable ingredients, including the innovative EcoSafe Zinc™, make it a game-changer for eco-conscious consumers seeking effective yet environmentally friendly skincare solutions.

“There is still a preconceived notion that zinc sunscreens are like the stuff lifeguards used on their noses in the 70s,” said Autumn Blum, founder of Stream2Sea. “This revolutionary formula applies sheer and non-greasy. We are incredibly proud to be part of the 4ocean team. 4ocean knows how to engage and empower people to clean up the ocean – we know how to make the safest sunscreens. Together, we have created an incredible product that protects people and the planet while removing five pounds of trash.”

Protecting Both our Bodies and our Oceans

The Reef-Safe Sunscreen Balm is more than just a skincare product; it’s a testament to our shared mission to protect our blue planet. Formulated without preservatives and with 100% mineral-based ingredients, including EcoSafe Zinc™, this balm provides broad-spectrum UVA/UVB protection without harming marine life or coral reefs. Coral bleaching, often exacerbated by chemical sunscreens containing harmful ingredients like oxybenzone, poses a significant threat to our oceans’ health. By choosing reef-safe alternatives like our sunscreen balm, consumers can play a vital role in preserving these vital ecosystems for future generations. Beyond its protective benefits, each purchase of the Reef-Safe Sunscreen Balm contributes to 4ocean’s ongoing efforts to combat ocean plastic pollution. With over 34 million pounds of plastic waste removed from our oceans to date, 4ocean is a driving force in the fight for cleaner seas.

“This is a huge win for the ocean,” said Alex Schulze, CEO and Co-founder of 4ocean. “We are stoked to offer a product that will help protect people from the sun’s harmful rays without damaging our coral reefs.”


While the launch of this sunscreen balm marks a significant step towards sustainable skincare, it’s essential to acknowledge ongoing discussions within the sunscreen industry. Recent scrutiny surrounding ingredients like butyloctyl salicylate (BOS) highlights the need for transparency and regulatory oversight in skincare formulations.

As consumers become increasingly aware of the potential risks associated with certain sunscreen ingredients, it’s crucial to prioritize safety and environmental sustainability in product development. By choosing reef-safe and environmentally friendly options, consumers can align their skincare routines with their values while protecting both their skin and the planet.

As we navigate the complex landscape of sunscreen science, our commitment to innovation, sustainability, and environmental responsibility remains steadfast. Together with 4ocean, we’re proud to offer a sunscreen balm that not only meets the highest safety standards but also supports ocean conservation efforts around the globe.
