Description

A consumer product comprising a container and at least one water soluble unit dose article.

Water-soluble unit dose articles are preferred by consumers for their convenience and ease of use. Without wishing to be bound by theory, the water-soluble unit dose article includes a water-soluble film shaped to form at least one interior compartment containing a single-use dose of detergent. Upon addition of the water-soluble unit dose article to water, the water-soluble film dissolves and/or decomposes, releasing detergent into the surrounding water to produce a cleaning solution.

Such water-soluble unit dose articles are stored and transported in rigid or flexible plastic containers. Without wishing to be bound by theory, a consumer purchases a container containing multiple water soluble unit dose articles. The containers are shipped from the manufacturing site to a supermarket and, once purchased, stored at the consumer's home.

Detergent compositions encapsulated in water-soluble unit dose articles typically include fragrance. The problem is that during transportation and storage, the fragrance partially transfers from the detergent composition through the water-soluble film and begins to accumulate in the headspace of the container. However, some consumers do not like strong fragrances to be applied to their clothes, for example, they may desire minimal fragrance application simply as a sign that their clothes are clean and refreshed. , you don't want to experience an "overwhelming" fragrance. For some consumers, strong fragrance headspace that accumulates in the tub is undesirable because it is perceived as a signal that strong fragrance will be applied to their clothes even during washing. Even when formulating "light" fragrances that target this consumer segment, fragrance build-up in the headspace experience should still be improved.

A potential solution could be for the consumer to store the container in an open position so that perfume headspace cannot build up. However, this is undesirable because it increases the sensitivity of the water-soluble unit dose article to external humidity conditions as well as the risk of accidentally contaminating the water-soluble unit dose article. More importantly, by leaving the container open, the risk of strong fragrances accumulating within the storage container is reduced, but this approach also consumes a reassuring signal that the detergent composition does not contain strong fragrances. do not provide it to anyone. Consumers will not know that there is no scented headspace on the basis of which they can determine whether a formulated fragrance matches their needs. Accordingly, the consumer shall ensure that such containers remain closed until intentionally opened, resulting in fragrance headspace build-up, and the consumer may, based on fragrance accumulation in the headspace, It is preferred to have a latch so that the intensity of the fragrance can be determined.

Accordingly, there is a need for consumer products that include water-soluble unit dose articles containing scented detergent compositions that avoid strong fragrance build-up in the headspace while stored in a closed position.

Surprisingly, it has been found that a consumer product according to the invention overcomes the above problems.

Example 1: Fragrance Headspace Dependency on Container Material Overly strong fragrance deposits on clothes washed with scented laundry detergent compositions are common among consumer segments seeking to avoid an overwhelming fragrance experience on clothes. , continued complaints about laundry-soluble unit-dose products. Fragrance accumulation in the headspace of the container during storage is used as a signal to assess the risk of "over-scenting" the garment during the wash cycle. In this study, we inter-compared the influence of storage container materials in terms of fragrance accumulation within the container headspace and more specifically found that compared to traditional market plastic type containers, paper-based containers It was variable.

Closed packages of similar dimensions containing 38 water-soluble unit dose articles were stored in a climate chamber at 20°C and 32°C for 20 and 35 days, after which the accumulated perfume headspace was analytically quantified. . Two replicates of each container type are tested and the average total headspace count is reported.

・Water-soluble unit dose article: Ariel 3 in 1 Pods, marketed in the UK in April 2019
・Comparative example: Plastic tab - Ariel 3 in 1 Pods polypropylene tab, commercially available in the UK in April 2019 (dimensions: length = 245 mm, height = 135 mm, width = 96 mm, quantity: 38)
・Example 1: Corrugated paper tab (dimensions: length = 245 mm, height = 135 mm, width = 96 mm, material: E-flute corrugated board 382 gsm KW2 135/RF1 90/board KW2 135, quantity: 38)
・Example 2: Corrugated paper tab with PE lamination (dimensions: length = 245 mm, height = 135 mm, width = 96 mm, material code GD2 210/HPF 140 (E-flute)/BKR 170+PE15

Test settings:
storage:
Two replicates of all container types were filled with 38 pouches and stored in a closed position in a constant temperature climatic chamber (20°C and 32°C) for 20 days, after which the perfume headspace was maintained as described herein. The results were analytically quantified as follows. After analytical quantification, the container was closed again and re-stored in the climatic chamber for an additional 15 days.

Analysis quantification:
The stored container was placed in a sealed plastic box in an open position and left for 1 hour to allow the perfume headspace to redistribute from the container into the plastic box. As a result, air was drawn from the box (10 minutes at constant flow rate) through an aerosol filter that captured perfume particles from the air gap. The aerosol filters were then analytically evaluated using GC/MS for the presence and quantification (mmol/L) of specific perfume particles. Table 1 summarizes the list of perfume materials analyzed. The amounts of individual perfume materials recovered were summed and the total headspace number obtained was reported.

result:
The total headspace results in Table 2 clearly show that, unlike plastic tubs, paper-based containers according to the invention (with or without lamination) exhibit significantly lower headspace accumulation during storage. .
