Definitions
- the present invention relates to aqueous cleaning compositions. More specifically it relates to non-ionic surfactant comprising aqueous cleaning compositions with reduced pH drift, and a method and use to achieve the same.
- Cleaning products are well-known and play an important role in everyday life. Such products will contain surfactant and, if disinfection is desired, usually also a disinfecting agent like for example a quaternary ammonium compound. Traditionally a distinction is made between personal hygiene, i.e. how one takes care of one's own body; and home care including laundry and household care, the latter including the cleaning of hard surfaces like floors and kitchen tops.
- US2017347644 A1 discloses a disinfectant cleaner composition comprising at least one quaternary ammonium compound, at least one antimicrobial amine, polyalkyl glucoside, and an anionic scale inhibitor.
- a cleaning product When washing laundry articles or cleaning hard surfaces like floors and kitchen tops, skin contact with the cleaning product usually occurs. A growing number of consumers expect cleaning products to be mild on skin such that it will not cause skin irritation, even when the cleaning product is not rinsed-off after contact. To address this need, a cleaning product may be formulated such that it has a neutral pH and therefore is mild on skin.
- Storage stability of a cleaning product is an important attribute. That is to say, the product should maintain its product properties over its entire lifespan. For example, some ingredients may be less stable over time and/or under elevated temperatures and formulators may address this by including higher amounts of such ingredients to compensate for this loss. Another example is product appearance, as sometimes a product may develop sediment and/or become cloudy, resulting in a less appealing appearance of the cleaning product. For cleaning products that are formulated to be mild on skin and therefore have a specific, often neutral, pH it is important that consumers can rely on the product maintaining this characteristic during product lifetime as otherwise the product may, unexpectedly, result in skin irritation when used.
- pH drift the pH of a product changes upon storage. This is sometimes referred to as 'pH drift'.
- the invention relates to an aqueous cleaning composition
- an aqueous cleaning composition comprising
