Each load of synthetic laundry can release hundreds of thousands of plastic microfibers into wastewater. With the average U.S. household running about 300 wash cycles annually, the need to reconsider laundry practices becomes evident—not just in terms of detergent, but also the chemicals that wash away, the plastic containers, and the residues left on clothing.
We are Orange House, a plant-based cleaning brand that utilizes food-grade orange oil. We aim to share our perspective on the trade-offs in sustainable laundry—focusing on concentration, packaging, residue, and third-party testing—because these decisions often go beyond the apparent, and consumers deserve more than just a “natural” label.
Why We Chose Orange Oil for Our Formulation
Orange oil is our primary active ingredient due to its natural effectiveness in cutting grease and removing stains. This choice marks a deliberate shift from chemical-heavy systems, still ensuring the cleaning results families expect. Plant-based does not equate to being less effective.
However, sustainability in laundry is not about a single ingredient. Each wash cycle impacts the environment through chemical discharge into wastewater and residues that remain on fabrics, contacting the skin. A strong formulation must address both aspects.
Some laundry additives, like fabric softeners and certain enhancers, can coat fabric surfaces and persist after rinsing. The American Cleaning Institute provides guidance on how these products interact with fibers. Our detergents are optimized to clean and rinse effectively, reducing residue build-up over time.
Testing for 1,4-Dioxane Impurities
Product safety involves not only the ingredients used but also what might inadvertently enter during production. 1,4-dioxane, a byproduct of certain surfactants and foaming agents, is classified by the EPA as a likely human carcinogen. It is not an ingredient but can form during manufacturing.
Since December 31, 2023, New York State law mandates that household cleaning products sold in the state contain no more than 1 ppm of 1,4-dioxane, a benchmark we adhere to.
Our finished-product testing, conducted by Intertek Testing Services Taiwan Ltd., follows a method aligned with USP-NF 2023 <467> for residual solvents, using Headspace Gas Chromatography-Mass Spectrometry (Headspace GC-MS). Tests between March 20 and March 27, 2026, with a limit of quantitation of 0.5 ppm, found no detectable levels of 1,4-dioxane in our formulation.
For us, sustainable laundry is more than a “natural” label. It means minimizing material use and reducing chemical exposure over time, with transparency through published data.
The Overlooked Packaging Trade-Off
Packaging is a critical area where many sustainability claims falter. Every detergent bottle becomes waste, and diluted formulas exacerbate the issue with more bottles, transportation weight, and emissions per wash.
We tackled this with a concentrated format, including our 4-liter design, which offers more washes per container. This efficiency reduces the number of bottles used annually, effectively cutting plastic waste without changing consumer habits.
We acknowledge a trade-off often overlooked. While paper-based containers appear eco-friendly, many require plastic linings that complicate recycling. A single-material plastic that gets recycled locally may be more effective in real-world scenarios than a multi-material paper container that ends up in landfill. Neither option is flawless; we selected what we believe is best suited for our customers’ waste streams.
Testing for Sensitive Skin
Trace detergent elements can linger in fabrics, impacting skin, especially for those with sensitive skin or atopic dermatitis, where residue can irritate the skin barrier. This underscores the importance of residue behavior alongside ingredient lists.
We conducted a Human Repeat Insult Patch Test (HRIPT), a dermatological standard, over six weeks with 108 participants, including those with sensitive skin. The test revealed no signs of irritation or sensitization.
Our aim is not to eliminate chemistry, but to optimize it. Our micellar orange oil technology combines citrus oil with structures that remove dirt with less detergent per wash. Our detergents are dermatologically tested and certified as an 85% biobased product by the USDA BioPreferred Program, validated through ASTM D6866 testing.
Considerations for Choosing Sustainable Detergents
Ultimately, choosing a better detergent requires informed decisions, not just marketing claims. Whether or not you choose Orange House, these are the questions to ask about any product:
- Concentration: How many washes per container? More concentrated formulas mean reduced plastic, shipping weight, and emissions per wash.
- Packaging Honesty: Is the container recyclable in your local system, or is it misleading multi-material packaging?
- Residue and Rinse-Out: Does the formula rinse clean, or does it leave residues you wear?
- Third-Party Testing: Is the product tested for contaminants like 1,4-dioxane by an accredited lab? Is the data available?
- Independent Certifications: Look for labels requiring third-party verification, like USDA Certified Biobased Product or EPA Safer Choice.
Innovation in formulation and packaging can align effective cleaning with environmental responsibility. Orange House was created to demonstrate this. Regardless of your detergent choice, these questions steer the industry toward better practices, one load at a time.
