FIELD OF INVENTION

The present application relates to alkaline compositions comprising an aminoalcohol solvent having an improved stability.

BACKGROUND OF THE INVENTION

Aminoalcohol solvents, and in particular monoelhanol amine (MEA) are typically used in many applications such as hair colorant, laundry cleaning composition, or hard surface cleaning composition.

The stability of those compositions is challenging, as the composition are alkaline, sometimes have a high pH, typically comprise a perfume formulation, and may further comprise highly reactive ingredients such as bleach.

The inventors have discovered that the stability issue could be alleviated in alkaline compositions comprising aminoalcohol by selecting a specific perfume formulation.

SUMMARY OF THE INVENTION

The present application relates to an alkaline composition comprising an aminoalcohol solvent and a perfume formulation, wherein the perfume formulation comprises at most 40%, per weight of perfume raw materials comprising an ester function, an a, β-unsaturated aldehyde function and/or an a, β-unsaturated ketone function.

The alkaline composition according to the invention has an improved stability.

DETAILED DESCRIPTION OF THE INVENTION

The composition

The composition is alkaline. The composition may have a pH between 7.2 and 14, or between 7.5 and 13.5, or between 8 and 13, or between 8.5 and 12.5, or between 9 and 12, or between 9.5 and 11.5, or between 10 and 11.

The composition may be a liquid composition. The composition may have a viscosity at shear rate 10 s ^" of 1 mPa.s or greater, more preferably of from 1 to 20.000 mPa.s, or from 1.5 to 1000 mPa.s, or from 2 to 300 mPa.s, or from 2.5 to 100 mPa.s at 20°C when measured with a DHR 1 rheometer (TA instruments) using a 2° 40mm diameter cone/plate geometry, with a shear rate ramp procedure from 1 to 1000 s ^~ \

The composition is typically an aqueous composition and therefore comprises water. The composition may comprise from 50% to 98%, or from 75% to 97%, or from 80% to 97% by weight of water.

The composition may be a laundry composition, for example a laundry composition in a water- soluble unit-dose pouch or a liquid laundry composition in a plastic bottle, or the composition may be a hair colorant, or the composition may be a hard surface cleaner composition.

Perfume formulation

The composition comprises a perfume formulation. The perfume formulation is a mixture of odorant perfume raw materials, such as aromatic natural oils and aromatic chemicals, which taken together form a complex scent that delivers a number of benefits. These benefits may include the coverage of product base odor, scenting the product itself, and lingering scent radiating from the surface into the air after treatment. When the composition is sprayed, the benefit may also include the delivery of scent to the air when spraying the composition on a surface, and the delivery of scent to the air while wiping the composition on the surface. The perfume formulation may comprise at least 3, at least 5, at least 7, at least 11, or at least 15 perfume raw materials.
