Definitions
- the present invention relates to toilet cleaner blocks, more particularly to toilet cleaner blocks comprising a surfactant mix of alkyl benzene sulfonate, primary alcohol sulphate and alkyl poly glycoside.
- Toilet cleaner blocks are commonly used to impart cleansing and/or other components to the flush water of toilets, like lavatories or urinals. Such blocks may be immersed in the water tank (so called in-tank blocks or cistern blocks) or held under the rim of a toilet in a suitable holder for intermittent contact of the toilet cleaner block with flush water (so called rim blocks).
- Rim blocks typically contain active ingredients such as surfactants, perfume, acids, bases, salts, thickeners, antimicrobials, preservatives, sequestrants, bleaching agents, corrosion inhibitors, flush regulators, enzymes, microorganisms, active substances for biofilm removal, lime-scale inhibitors, soil-adhesion inhibitors etc. Rim blocks also often contain a substantial amount of filler, such as sodium sulphate or sodium carbonate.
- Solid toilet blocks are typically manufactured and shaped by an extrusion process.
- the shaped toilet blocks may be inserted into a suitable holder, like for example a basket, for use in the toilet bowl.
- 3D shape how the 3D shape of the block changes during its lifetime.
- the block gradually dissolves under the influence of flush water. Ideally the block dissolves symmetrically such that the overall 3D shape of the block is maintained during its lifetime. It may happen that a block dissolves asymmetrically, for example one side erodes excessively, the block develops holes, or may become porous such that part of the block breaks off; • Foam development - how much visible foam develops during a flush as well as how much and how long visible foam is present after a flush. This is usually measured as cm of foam;
- a harder toilet block will have a longer lifespan but may not perform well on foam development.
- US2012047640 discloses malleable toilet cleaner compositions comprising a) perfume; b) at least one nonionic surfactant; c) at least one alkyl benzene sulphonate; and d) at least one olefin sulfonate.
- WO2019/052842 discloses shaped toilet cleaner blocks comprising a surfactant system consisting of alkyl benzene sulphonate and nonionic surfactant wherein the nonionic surfactant preferably is a fatty alcohol alkoxylate.
- shaped toilet cleaner blocks comprising a surfactant system of alkyl benzene sulphonate, primary alcohol sulphate and alkyl poly glycoside allow for improved in-use characteristics.
- the invention relates to a shaped toilet cleaner block comprising: a. a surfactant mix comprising: i. 10 to 30 wt% alkyl benzene sulphonate; i. 1 to 25 wt% primary alcohol sulphate; i. 1 to 15 wt% alkyl poly glycoside; b. 30 to 85 wt% filler; c. 0 to 7 wt% polyol with a carbon chain length of 2 to 4; d. 0 to 2 wt% water; wherein the weight ratio of (alkyl benzene sulphonate + alkyl poly glycoside)/primary alcohol sulphate is from 0.5:1 to 7:1.
- the invention further provides a toilet cleaning system comprising at least one toilet cleaner block according to the present invention and a holder suitable for positioning the toilet cleaner block in a toilet bowl such that it is wetted when the toilet is flushed.
