Description

Technical Field

[0001] This invention relates to transparent liquid fragrance enhancers. Background Technology

[0002] In addition to any detergent or fabric conditioner, fragrance enhancers are used during the laundry process to deliver a scent. Fragrance enhancers allow consumers to customize their fragrance experience during laundry. Consumers can choose the fragrance and the amount of product to be added. This avoids overusing products like fabric conditioners to increase fragrance delivery. Consumers also expect transparent products, as transparency signals that the product is free of high levels of chemicals. There is a demand for transparent liquid fragrance enhancers; however, transparent formulations offered in recycled resin bottles present stability issues. Summary of the Invention

[0003] Research has found that careful selection of nonionic surfactants can improve the stability of transparent fragrance enhancers in post-consumer recycled resin bottles.

[0004] Therefore, in one aspect of the invention, a container comprising a transparent laundry fragrance enhancer composition is provided, wherein the transparent laundry fragrance enhancer composition comprises: a) Spices; and b) Ethoxylated triglycerides; The container contains 25 to 100% by weight of post-consumer recycled resin.
