Description

[0001]P0000411EP CPL 1 SOLID LAUNDRY COMPOSITION Field of the Invention The present invention relates to a solid laundry detergent composition. The invention 5 particularly relates to a solid, free flowing, particulate laundry detergent composition having a low pH profile. Background of the Invention Solid laundry detergent composition typically has an alkaline pH. This alkaline pH profile 10 ensures good cleaning performance by saponification of grease and cleaning by the mechanism of swelling the fibers of fabric. However, the alkaline pH range may cause fading of some fabric dyes over multiple laundry cycles. In addition to fading of fabric colour, the alkaline detergent composition are likely to irritate the 15 skin when traces of the composition remain on the clothing after rinse. Other concerns which additionally need to be addressed while formulating the solid laundry detergent composition with high pH profile include improving the fabric care benefits, fabric appearance performance and / or fabric shape retention performance. 20 It is known to address these concerns of detergent composition with high pH profile, by lowering the pH of the composition which offer the advantage of being less harsh to skin and reduces color fading. It is known in the art to formulate the solid detergent composition at a lower pH and then to balance the formulation with specific ingredients to provide good cleaning performance. 25 One such document is EP 3301158 A1 (P&G, 2018) which discloses a solid free flowing particulate laundry detergent composition having a pH ranging from 6.5 to 8 and where the composition includes alkoxylated polyalkyleneimine and a base detergent particle having 1 wt.% to 10 wt.% organic acid and an anionic surfactant. 30 One concern with solid laundry detergent composition having a low pH base detergent particle comprising an organic acid, is the deliquescent nature of organic acid particularly citric acid. The deliquescent nature of citric acid particularly when added in an amount ranging from 1 wt.% to 10 wt.% was found to be detrimental to the physical stability of the product containing the citric acid, particularly in hot and humid conditions which are common in most parts of the world. 35 By deliquescent it is meant that citric acid forms a hydrate from moisture and then proceeds to P0000411EP CPL 2 dissolve in its own water of hydration. In granular detergent composition, presence of citric acid may result in lumpy, cakey, and poor flowability of the composition. Consumer studies indicate that when the pH of the composition is lowered, consumers tend to 5 wash the fabric over longer wash cycles to achieve the desired cleaning performance. The longer wash cycles tend to hasten the fabric damage. Low pH compositions with a reduction in the pH improves the fabric care benefits which is seen in the better color retention seen in fabrics washed with the composition. The composition may10 still render the fabric stiff after the wash cycle due to the longer wash cycles. Consumers correlate the fabric care benefits with the softness of the fabrics felt after the laundering process. When the fabrics have a certain amount of stiffness after the wash, the laundry detergent composition is perceived to be harsh on the fabrics. To overcome this 15 problem, it is known to add fabric conditioners which contain cationic ingredients. However, today’s consumer desire for a single composition which provides both fabric cleaning performance and the fabric care benefits. Thus, it is desired to provide a laundry detergent composition which provides good softness sensorials along with cleaning performance and fabric care benefits which includes color retention and fabric softness. 20 It is therefore desired to provide a solid free flowing laundry detergent composition which has a pH ranging from 6.5 to 9 and which provides good stain removal performance in shorter wash cycles and thereby delivers good fabric care performance. 25 It is also desired to provide a low pH solid laundry composition which provides good powder properties and storage properties over long periods without caking. Another requirement is to provide a solid laundry detergent composition which is biodegradable, and which exhibits improved cleaning performance. 30 Summary of the Invention The present invention addresses this need by incorporating a combination of a specific low pH spray dried detergent particle and a specific fabric softening agent in a solid detergent composition to provide desired softness benefits while maintain cleaning performance in shorter 35 wash cycles and which delivers good fabric care performance.
