Kirkland Signature Laundry Detergent

Kirkland Signature is the private-label brand of Costco Wholesale Corporation. This specific product is a concentrated liquid laundry detergent marketed as scent-free and dye-free, designed to be dermatologically tested for sensitive skin. The brand was launched in 1995 to provide high-quality alternatives to national brands at a lower price point.

While the label indicates distribution by Costco Wholesale Canada Ltd., Kirkland Signature laundry products are typically manufactured through third-party supply chain partners in several countries, with a significant portion of their liquid cleaning supplies produced in the United States and Canada. As Costco’s house brand, it remains under the direct management and ownership of the parent corporation.
