Key Differences Between ECOS And Seventh Generation
While ECOS and Seventh Generation share many similarities as eco-friendly laundry detergents, some key differences set them apart. Let’s take a closer look at these distinctions.
- Ingredients

Both ECOS and Seventh Generation use plant-based, biodegradable ingredients, but there are some differences in their specific formulations.
ECOS uses a blend of coconut-based surfactants, natural enzymes, and essential oils to create its effective cleaning formula.
ECOS also emphasizes the use of hypoallergenic ingredients, making it a good choice for those with sensitive skin.
Like ECOS, Seventh Generation relies on plant-based surfactants and enzymes.
However, the brand also incorporates a unique triple enzyme formula that targets tough stains and odors. Seventh Generation’s ingredients are also hypoallergenic and designed to be gentle on skin.
- Packaging
While both brands use recycled plastic in their packaging, there is a notable difference in the percentage of post-consumer recycled content.
One of the standout features of ECOS is its commitment to using 100% post-consumer recycled plastic in its packaging. This means that all of the plastic used in ECOS bottles has been recycled from previous consumer waste, helping to reduce the demand for new plastic production.
In contrast, Seventh Generation uses 80% post-consumer recycled plastic in its packaging. While this is still significant and helps reduce waste, it’s not quite as impressive as ECOS’s 100% commitment.
- Scent Options
Both ECOS and Seventh Generation offer a range of scent options, including natural fragrances and unscented varieties. However, there are some differences in the specific scents available.
ECOS offers a wide range of natural scents, such as lavender, lemongrass, and magnolia & lily. ECOS also has an unscented option for those who prefer a fragrance-free laundry experience.
While Seventh Generation also offers a variety of natural scents, such as blue eucalyptus & lavender and fresh citrus & sandalwood, some users have reported that the fragrances can be a bit strong or polarizing. Like ECOS, Seventh Generation also provides an unscented option.
- Price Point

One of the most noticeable differences between ECOS and Seventh Generation is their price point.
Generally speaking, ECOS tends to be more affordable than Seventh Generation.
This makes it a more budget-friendly option for those looking to make an eco-conscious choice without breaking the bank.
While still competitively priced compared to many conventional detergents, Seventh Generation is often slightly more expensive than ECOS.
This higher price point may be a consideration for cost-conscious consumers.
- Cleaning Performance
Both ECOS and Seventh Generation are known for their effective cleaning performance, but there may be some slight differences depending on the specific type of stain or odor.
Many users report that ECOS effectively tackles a wide range of stains and odors, leaving clothes fresh and clean. However, some particularly stubborn stains may require pre-treatment or additional effort.
With its triple enzyme formula, Seventh Generation is often praised for its ability to handle tough stains and odors. Some users find that it performs slightly better than ECOS on heavily soiled items.
