The disclosure relates to a detergent composition useful for hygiene, consumer or home care products such as dishwashing, laundry, dish hand-washing liquid and other household detergent-based compositions.
Currently, there is a need in the art to provide a detergent composition for end-user formulation of consumer/home care, or hygiene products containing low or high surfactant levels; whereby the composition provides superior detergency (cleaning) in comparison to commercially available products, requiring less energy (heating), less water and provides quicker wash cycles during use, without the penalty of a very high energy usage. Further, there is a need in the art for detergent compositions which can be prepared from naturally derived ingredients or “green” ingredients, in particular, naturally derived nonionic surfactants which can provide a natural based detergent composition.
There is a need in the consumer care sector for low-energy washes which provides the desired detergency action and which output a smaller amount of heat and mechanical energy, saving the consumer costs and decreasing energy consumption. Through a focus on surfactant development based upon natural, plant-derived materials, hygiene, or consumer/home care detergent-based products upon the addition of polyglyceryl esters offer improved cleansing efficacy in comparison to current commercially available detergents-based products. Additionally the use of polyglyceryl fatty esters as an alternative surfactant to the use of non-ionic surfactants may assist in the wash time reduction, lower energy usage, and less water wastage ultimately leading to a more environmentally friendly and cost friendly product. Additionally, the use of natural sources of polyglyceryl fatty esters as one of the main components in such compositions, results in a more bio-based detergent composition for end-user products, in comparison to current bio-based commercial products. Furthermore, the addition of polyglyceryl fatty esters overcomes the current issues of detergent compositions demanding high surfactant levels, where such detergent-based compositions are currently impossible in fluid form. Therefore the addition of one or more polyglyceryl fatty esters helps overcome these issues, allowing for fluid, gel forms of detergent compositions having high surfactant levels for improved detergency.

These and other aspects will become apparent when reading the detailed description.
It has now been surprisingly found that polyglyceryl fatty acid esters may be used to supplemental or replace other non-ionic surfactants for compositions requiring such surfactants. The addition of polyglyceryl fatty esters, have also shown to work well in combination with other surfactants for compositions and end-user formulations. The present disclosure provides a composition whereby the surfactant contains one or more of a polyglyceryl fatty ester and may further contains one or more anionic surfactants or amphoteric surfactants, aiding the properties of detergent-based compositions, without affecting the properties of the formulation itself.
Additionally, the aesthetic properties and rheological behavior of polyglycerol esters means that additional components (such as humectants, viscosity modifiers), although not required; may be added to the end user formulation, if desired, without affecting the properties of the formulation itself.
In accordance to the present disclosure, the term “builders” herein, refer to substances which deal with hard-water molecules during the washing process, allowing surfactants get on with their job of removing stains. They are responsible for removing the hardness ions so the surfactant can be fully functional.
In accordance to the present disclosure, the term “anti-redeposition agents” herein, refer to soil release substances which keep the soil particles suspended in the wash liquor so they do not get deposited back on the fabric.
In accordance to the present disclosure, the term “enzymes” herein, refer substances which are naturally occurring proteins that break down stains into smaller pieces to make them easier to remove. There are several different types of enzymes present in your washing detergent, each of which works to break down and remove a specific type of stain like grass, blood, tough stain removal, color and fabric care, grease, oils (starch based), gravy by breaking them down to smaller, easily removable components, help whiten and brighten, protein stains, and the like.
In accordance to the present disclosure, the term “surfactants” herein, refer to substances having a core stain removing function in a detergent composition. This refers to any substance which removes anything greasy from fabrics, and they work well on stains and food residues.
The term “HLB” herein, refers to “hydrophilic-lipophilic balance”. The HLB value expresses the water and oil solubility of, in particular, non-ionic, emulsifiers (i.e. it expresses the lipophilic and hydrophilic properties of an emulsifier, which are determined by the different parts of the emulsifier molecules). The higher the HLB of an emulsifier, the more hydrophilic and water soluble it is. According to the Griffiths method, HLB is calculated via: HLB=(molecular weight of hydrophilic head-group/total molecular weight)*20.
The term “waxes” herein, refers to naturally-occurring or synthetic waxes, of which typical examples include stearyl alcohol, hydrocarbon waxes, waxes of plant or animal origin, their synthetic analogues or derivatives, or silicone waxes. Waxes are widely available, and by suitable selection of the waxes themselves and their concentrations in the formulation can effectively obtain either a soft solid or a firm solid. Conventionally, waxes are applied to a variety of materials and mixtures which have similar physical properties, namely that: they are solid at about 30° C. to about 40° C.; they melt to a mobile liquid at a temperature above 30° C., and below 95° C.; generally in a temperature range of 40° C.-90° C.; and they are water-insoluble and remain water-immiscible when heated above their melting point.
The term “oils” herein, refers to an organic compound which at about 20° C. is both liquid and water-insoluble. In the context of the disclosure, insolubility in water is understood to be a solubility of less than 10 w/w % at about 20° C. Typically, the solubility of less than 1 w/w %, more particularly less than 0.1 w/w %, in particularly less than 0.01 w/w %.
The term “aqueous alcohol” herein, refers to saturated, unsaturated, straight or branched hydrocarbon chain having C1-C4 carbon atoms and at least one hydroxyl groups, wherein the hydrocarbon chain may optionally contains one or several heteroatoms (such as oxygen or sulfur). The aqueous alcohol will contain at a minimum an amount of water.
The term “green surfactant’ used herein is the Renewable Carbon Index (RCI). The RCI is the percentage of the carbon atoms in each surfactant molecule that originate from renewable resources (typically oil-producing plants) rather than from fossil resources. So, for example, the surfactant sodium coco-sulfate, having a tail-group carbon chain derived entirely from palm kernel oil and/or coconut oil, and having no carbon in the surfactant head-group, has an RCI value of 100. Under the RCI definition of ‘greenness’, this can be considered to be a ‘100% green’ surfactant. In contrast, an alkyl benzenesulfonate surfactant, having a tail-group carbon chain derived entirely from fossil resources, has an RCI value of 0. Under the RCI definition of ‘greenness’, this can be considered to be a ‘100% black’ surfactant. If we consider the surfactant sodium laureth sulfate with 3 moles of ethoxylation, this may have an RCI value of 0 if the tail-group carbon chain is derived from fossil resources or it may have an RCI value of 67 if the tail-group carbon chain is derived from renewable plant resources. This calculation assumes that the carbon in the ethylene oxide portion of the surfactant head-group originates from fossil resources. For non-ionic surfactants, a similar calculation can be done. For a typical alcohol ethoxylate surfactant such as C12EO6, the RCI value is 0 if the tail-group carbon chain is derived from fossil resources. If the tail-group carbon chain is derived from renewable resources, the RCI value is 50 because the carbon in the ethylene oxide head-group is invariably derived from fossil resources. Obtaining non-ionic surfactants with an RCI value of 100 suitable for use in the detergent applications described herein has been hitherto technically difficult to achieve. The RCI value of the polyglyceryl fatty acid esters non-ionic surfactants described herein is 100.
