Definitions
- the present invention relates to improved detergent compositions.
- WO 2017/027271 discloses methods for producing detergent compounds from waste plastic feedstocks. More specifically, the invention relates to methods for producing detergent intermediates, including alkylbenzenes, paraffins, olefins, oxo alcohols, and surfactant derivatives thereof from waste plastic feedstock.
- WO 2020/178597 (Oxford Sustainable Fuels Ltd) discloses a process for upgrading a pyrolysis oil derived from plastic or rubber.
- LAS linear alkyl benzene sulphonate
- the LAS produced is complex mix of compounds with varying chain length and isomers.
- the properties of LAS are determined by the composition of the mixture. This is particularly key when used in laundry liquid detergent, as small changes in structure can dramatically change the product viscosity and stability.
- Plastic waste is a key issue. Many plastics cannot be recycled by mechanical means, an alternative is chemical recycling. In chemical recycling the plastic is pyrolysed to produce pyrolysis oil, a complex mixture of aromatics, alkanes, cycloalkanes, alkenes, cycloalkenes and oxygenates. Chemical recycling of plastic waste: Bitumen, solvents and polystyrene from pyrolysis oil in H/aste Management 118 (2020) 139-147 by Baene-Gonzalez et al illustrates a typical product mix from pyrolysis oil.
- Agricutural and waste products such as oils, plant shells and husks may also be used to make pyrolysis oil.
- pyrolysis oil Once produced pyrolysis oil may be distilled to give the necessary raw materials to make LAS.
- the LAS so produced is not of the same specification as the petrochemical produced LAS due to the presence of minor components, that cannot be removed from the pyrolysis oil, such as low levels of other aromatics than benzene for example styrene and styrene derivatives. This difference means that pyrolysis produced LAS cannot be simply interchanged with petrochemical LAS due to the change in component make-up.
- the amount of pyrolysis-based LAS is such that it compensates for the plastic packing used to transport the liquid detergent, by a factor of greater than 1 , more preferably great than 10, most preferably greater than 100 times.
- LAB is typically manufactured using petroleum feedstocks on a large scale by the petroleum industry.
- LAB is converted to LAS by smaller industrial plants before being incorporated as LAS acid in detergent compositions.
- the LAS acid is neutralised by a counterions with alkali metal salts or ammoniacal salts.
- LAS The key to LAS’s success in detergent formulations is that it is a varied mixture of components. Variety resides in the number of carbon atoms in the alkyl chain as well as the point in the alkyl chain that the alkyl chain is linked to the benzene ring. There also exist isomers of LAS for example the 2-phenyl isomer which appears relevant to the overall performance of LAS in use.
- the variety of materials present in a LAS batch also figures in the supply chain.
- the LAS, (or more correctly LAB) produced is influenced by the feedstock. Different petroleum feedstocks will produce different LAB mixtures. In the consumer products industry this is managed with reference to a specification which covers a range of LAB characteristics. The specification is designed to ensure that no matter the actual nature of any one sample, that it is able to function as required in a detergent formulation.
- a detergent formulation Functioning in a detergent formulation, in particular a liquid formulation is also important, not just for the detergency benefit provided by the LAS but the influence on the performance of other materials in the liquid laundry detergent composition.
- Fragrances, surfactants, fluorescers and preservatives are heavily influenced by the nature of LAS and the specification is designed to ensure that these materials are not unduly affected by the varying nature of the LAS. For this reason the incorporation of different feedstocks into the supply chain, while desirable, has huge consequences on the performance of LAS and also the other materials commonly found in laundry compositions.
- a detergent composition comprising verdyl acetate and linear alkyl benzene sulphonate (LAS) obtained from waste plastic feedstock.
- LAS linear alkyl benzene sulphonate
- the detergent composition comprises verdyl acetate and linear alkyl benzene sulphonate (LAS) obtained from petroleum feedstock and LAS obtained from waste plastic feedstock.
- LAS verdyl acetate and linear alkyl benzene sulphonate
- waste plastic feedstock can be incorporated into the detergent composition without any undue effect on the fragrance ingredients in the formulation.
- the compositions remains hedonically stable and the performance of some ingredients is improved.
- the performance of a number of the ingredients is improved.
- the surfactant component which preferably also comprises alkyl ether sulphate and/or alcohol ethoxylate.
- the performance of these ingredients is diminished.
- the laundry composition comprises from 1 to 40% LAS, more preferably from 2 to 10% wt. LAS.
- the LAS obtained from waste plastic source comprises from 0.1 to 15%, preferably from 1 to 8% wt. of the total LAS present.
- the LAS obtained from waste plastic feedstock comprises alkyl chains with an average chain length from 8 to 14 carbons, more preferably from 10 to 13 and most preferably from 11 to 12.
- at least 30% wt. of the LAS obtained from waste plastic feedstock comprises alkyl chains with 12 carbons.
- at least 30% wt. of the LAS obtained from waste plastic feedstock comprises alkyl chains with 11 carbons.
- the pyrolysis LAS is made via an alkylation reaction of benzene with an n-alkyl, then sulphonation.
- alkyl chains obtained from the pyrolysis oil and used to make the LAS have a distillation range of 174 to 220°C.
- the wt. ratio of (A):(B) is from 2:1 to 1 :2, more preferably from 3:2 to 1 :2, most preferably 5:4 to 4:5 in the pyrolysis LAS.
- these two isomers represent from 20 to 70wt% of the pyrolysis LAS, more preferably from 30 to 40wt%.
- nonbenzene aromatics based side products may be produced, for example addition of the alkyl chain to styrene or addition of styrene to benzene.
- Toluene based products are another example.
- LAS adducts with non-benzene aromatics are less than 2wt% of the pyrolysis LAS.
- LAS adducts with styrene are less than 1wt% of the pyrolysis LAS.
- Styrene monomers may be removed from pyrolysis oil by for example distillation or polymerisation and extraction.
- the benzene required for LAS synthesis is obtained from pyrolysis oil and the alkyl from plant sources.
- Olefiin can be obtained from plant oils by metathesis reactions as described in Angewandte Chemie International Edition ; 51 (2012), 24. - S. 5802-5808 by Samir Chikkali and Stefan Mecking.
- both the benzene component and the alkyl component are obtained from waste plastic sources.
- the composition comprises verdyl acetate.
- the verdyl acetate is preferably present at from 1 to 20% wt. of the total free fragrance present in the composition.
- free fragrance is meant fragrance which is not encapsulated as part of a delayed or controlled release mechanism.
- the composition preferably comprises octahydro tetramethyl acetophenone (OTNE).
- OTNE octahydro tetramethyl acetophenone
- the OTNE is preferably present at from 1 to 40% wt. , more preferably from 10 to 35% wt. of the total free fragrance present in the liquid laundry composition.
- free fragrance is meant fragrance which is not encapsulated as part of a delayed or controlled release mechanism.
- the OTNE comprises octahydro-2', 3', 8', 8'-tetramethyl-(2')-acetonaphthone and/or octahydro-2', 3', 8', 8'- tetramethyl-(3')-acetonaphthone.
- the composition comprises dihydromyrcenol.
- the dihydromyrcenol is present at from 1 to 40% wt., more preferably from 10 to 35% wt. of the total free fragrance present in the liquid laundry composition.
- free fragrance is meant fragrance which is not encapsulated as part of a delayed or controlled release mechanism.
- the composition is contained in a container which comprises from 1 to 100% wt., more preferably from 20 to 100, and most preferably from 50 to 100% post-consumer recycled resin (PCR).
- PCR post-consumer recycled resin
- the laundry composition according to any preceding claim contained within a water- soluble capsule.
- the detergent composition is a laundry liquid detergent composition, a powder laundry detergent composition or a liquid dishwash composition.
- fragrance performance/choice Improvement in fragrance performance/choice are also highly desirable. Fragrances are often the most persuasive sensory component in a product and the behaviour of fragrances are strictly controlled such that too much does not leave the product such that none remains to be deposited on the fabrics during washing. Not enough leaving the product leads to a product with poor hedonics. In particular, we have found that performance benefits are seen with using di hydromyrcenol (DHM), a specific fragrance component when using waste plastic feedstock based surfactant raw materials.
- DAM di hydromyrcenol
- Improvement in visuals, in particular colour perception through film is also a sensitive formulation constraint.
- the light absorbance spectrum of a product is a key factor in a product’s colour stability. Not only can this lead to a variety in colour offerings between different products (where different products are affected differently by extraneous ultraviolet light, e.g. from the sun) but also the physical behaviour, in particular physical stability.

- Polycondensation involves forming a dispersion or emulsion of the core material in an aqueous solution of precondensate of polymeric materials under appropriate conditions of agitation to produce capsules of a desired size, and adjusting the reaction conditions to cause condensation of the precondensate by acid catalysis, resulting in the condensate separating from solution and surrounding the dispersed core material to produce a coherent film and the desired microcapsules.
