If it harms the ocean, it doesn’t come into our home.
A few summers ago our neighbour laid down a house rule that stuck with us: “If it harms the ocean, it doesn’t come into our home.” Whenever friends or family visit, they’re asked to swap out any conventional body products for genuinely ocean-safe alternatives—and more often than not they end up at our store to stock up on ocean-safe body products before they’re allowed through the door.
That simple practice got us thinking: what does “ocean-safe” really mean, which ingredients actually threaten marine life, and how can hemp help? The answers turned into the guide you’re reading now.
Every time we rinse shampoo suds down the plug-hole or lather on body wash at the beach, thousands of chemical compounds ride that water all the way to the ocean. Waste-water treatment removes many of them, but not all—and coastal showers or outdoor taps send products straight into the sea. “Ocean-safe” body-care promises to break that cycle.
| Must-Have Feature | Why It Matters for Marine Life |
| Readily biodegradable (breaks down to CO₂, water & biomass in < 28 days) | Reduces long-lived residues that build up in sediments and fish tissue. |
| Free of reef-toxins (e.g., oxybenzone, octinoxate) | These sunscreen filters can bleach coral, disrupt algae and damage juvenile reef fish. |
| No micro-plastics or “rinse-off” glitter | Polyethylene beads and plastic shimmer < 5 mm are eaten by plankton and work their way up the food chain. |
| No persistent silicones & PFAS | “Forever-chemicals” resist breakdown, accumulate in wildlife and even Arctic ice. |
| Low-toxicity, plant-based surfactants (e.g., coco-glucoside) | Conventional SLS/SLES can stunt growth of marine invertebrates; milder alternatives are safer and biodegradable. |
| Common Ingredient | Verified Marine Impact |
| Oxybenzone & Octinoxate (chemical sunscreens) | Coral DNA damage, bleaching at 62 ppb; banned in Hawai‘i & Palau. |
| Triclosan (antibacterial agent) | Disrupts hormone systems in fish; persists in estuary sediments. |
| Quats (benzalkonium chloride, cetrimonium bromide) | Toxic to crustaceans at < 1 ppm; slows algae photosynthesis. |
| PET / PMMA Microbeads | Consumed by zooplankton → fish → seabirds; can adsorb PCBs & heavy metals. |
| D4 & D5 Silicones | Bio-accumulate in mussels & seals; remain in seawater > 3 years. |

Bottom line: a hemp-based formula can meet every bullet in the ocean-safe checklist while delivering skin-loving fatty acids, vitamin E and antioxidants.
All formulations at Margaret River Hemp Co. are:

🌺 100% Natural ingredients (no nasties for you or our oceans)
♻️ Bottled in post-consumer recycled or glass packaging
The ocean gives us waves to ride, seafood to eat, and half the oxygen we breathe. Choosing genuine ocean-safe body products is one of the simplest everyday actions we can take to protect it. Next time you lather up, remember: what goes down the drain doesn’t disappear—it goes home to the sea. Make sure it’s something the sea can welcome back.
