## Title
Consumer goods product comprising functionalised lignin oligomer

## Abstract

A consumer goods product comprising a consumer goods product ingredient and a cross-linked co-polymer of a lignin oligomer and a vinyl monomer, wherein the lignin oligomer has: (a) comprises less than 1 wt % sulphur content; (b) has a number average molecular weight (Mn) of from 800 Da to 1,800 Da; and (c) has an average number of lignin monomers of from 3 to 8.

## Background
FIELD OF THE INVENTION
The present invention relates to consumer goods products comprising functionalized liginin oligomer.
BACKGROUND OF THE INVENTION
Cross-linked co-polymers based vinyl monomers such as acrylic acid and/or methacrylic acid provide rheology modification benefits. However, the cross-linking agents commonly used to make these cross-linked co-polymers such as divinyl benzene are highly hydrophobic and not readily soluble in water. Therefore, the cross-linking increases the hydrophobicity of the final cross-linked co-polymer.
The use of lignin-oligomers as cross-linking agents for polymers based on vinyl monomers results in cross-linked co-polymers without the unwanted increase in hydrophobicity. These cross-linked co-polymers exhibit improved solubility.
SUMMARY OF THE INVENTION
A consumer goods product comprising a consumer goods product ingredient and a cross-linked co-polymer of a lignin oligomer and a vinyl monomer, wherein the lignin oligomer has: (a) comprises less than 1 wt % sulphur content; (b) has a number average molecular weight (Mn) of from 800 Da to 1,800 Da; and (c) has an average number of lignin monomers of from 3 to 8.

Method of Measuring Sulphur Content:
The chemical composition of a lignin sample in terms of its carbon (C), hydrogen (H), nitrogen (N) and sulphur (S) content can be determined by elemental analysis in form of a CHNS analysis of at least three different representative samples of a given batch of the respective lignin. Typical sample sizes are 2.0 mg of a lignin sample that was oven-dried at 105° C. until a steady weight was obtained. The samples are placed in aluminum dishes and analyzed using a Carlo-Erba NA 1500 analyzer, using helium as carrier gas. Carbon (C), hydrogen (H), nitrogen (N) and sulphur (S) were detected in form of carbon dioxide, water, nitrogen, and sulphur dioxide, which are chromatographically separated to exit the instrument in the order of nitrogen, carbon dioxide, water, and sulphur dioxide. Quantification is achieved against calibrations using typical standard substances used for the calibration of elemental analysers, such as (bis(5-tert-butyl-2-benzo-oxazol-2-yl) thiophene, based on the peak areas of the chromatograms obtained for each lignin sample.
Method of Measuring Mn and Mw:
The number average molecular weight, Mn, as well as the weight average molecular weight, Mw, can be determined using gel permeation chromatography (GPC). Prior to analysis, representative lignin samples are acetobrominated as reported in archival literature (J. Asikkala, T. Tamminen, D. S. Argyropoulos, J. Agric. Food Chem. 2012, 60, 8968-8973.) to ensure complete solubilisation in tetrahydrofuran (THF). 5 mg lignin is suspended in 1 mL glacial acetic acid/acetyl bromide (9:1 v/v) for 2 h. The solvent is then removed under reduced pressure, and the residue is dissolved in HPLC-grade THF and filtered over a 0.45 μm syringe filter prior to injection into a 20 μL sample loop. Typical analysis set-ups resemble the following specific example: GPC-analyses are performed using a Shimadzu instrument consisting of a controller unit (CBM-20A), a pumping unit (LC 20AT), a degasser unit (DGU-20A3), a column oven (CTO-20AC), a diode array detector (SPD-M20A), and a refractive index detector (RID-10A); the instrumental set-up is controlled using the Shimadzu LabSolution software package (Version 5.42 SP3). Three analytical GPC columns (each 7.5×30 mm) are connected in series for analyses: Agilent PLgel 5 μm 10000 Å, followed by Agilent PLgel 5 μm 1000 Å and Agilent PLgel 5 μm 500 Å. HPLC-grade THF (Chromasolv®, Sigma-Aldrich) is used as eluent (isocratic at 0.75 mL min−1, at 40° C.). Standard calibration is performed with polystyrene standards (Sigma Aldrich, MW range 162-5×106 g mol−1), and lower calibration limits are verified/adjusted by the use of synthesized dimeric and trimeric lignin models. Final analyses of each sample is performed using the intensities of the UV signal at λ=280 nm employing a tailor-made MS Excel-based table calculation, in which the number average molecular weight (Mn) and the weight average molecular weight (Mw)) is calculated based on the measured absorption (in a.u.) at a given time (min) after corrections for baseline drift and THF-stemming artifacts.

Eventually necessary adjustment of Mn and Mw with respect to the desired applications is achieved by mechanical breaking of polymeric lignin using a ball mill, by chemically or enzymatically polymerising oligomeric lignin.
Method of Measuring Aromatic Hydroxyl and Aliphatic Hydroxyl Content:
Typically, a procedure similar to the one originally published can be used (A. Granata, D. S. Argyropoulos, J. Agric. Food Chem. 1995, 43, 1538-1544). A solvent mixture of pyridine and (CDCl3) (1.6:1 v/v) is prepared under anhydrous conditions. The NMR solvent mixture is stored over molecular sieves (4 Å) under an argon atmosphere. Cholesterol is used as internal standard at a concentration of 0.1 mol/L in the aforementioned NMR solvent mixture. 50 mg of Cr(III) acetyl acetonate are added as relaxation agent to this standard solution.
Ca. 30 mg of the lignin are accurately weighed in a volumetric flask and suspended in 400 μL of the above prepared solvent solution. One hundred microliters of the internal standard solution are added, followed by 100 μL of 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane (Cl-TMDP). The flask is tightly closed, and the mixture is stirred for 120 min at ambient temperature. 31P NMR spectra are recorded using suitable equipment, similar or identical to the following example: On a Bruker 300 MHz NMR spectrometer, the probe temperature is set to 20° C. To eliminate NOE effects, the inverse gated decoupling technique is used. Typical spectral parameters for quantitative studies are as follows: 90° pulse width and sweep width of 6600 Hz. The spectra are accumulated with a delay of 15 s between successive pulses. Line broadening of 4 Hz is applied, and a drift correction is performed prior to Fourier transform. Chemical shifts are expressed in parts per million from 85% H3PO4 as an external reference. All chemical shifts reported are relative to the reaction product of water with Cl-TMDP, which has been observed to give a sharp signal in pyridine/CDCl3 at 132.2 ppm. To obtain a good resolution of the spectra, a total of 256 scans are acquired. The maximum standard deviation of the reported data is 0.02 mmol/g, while the maximum standard error is 0.01 mmol/g. (A. Granata, D. S. Argyropoulos, J. Agric. Food Chem. 1995, 43, 1538-1544). Quantification on the basis of the signal areas at the characteristic shift regions (in ppm, as reported in A. Granata, D. S. Argyropoulos, J. Agric. Food Chem. 1995, 43, 1538-1544) is done using a tailor-made table calculation in which the abundances, given in mmol/g, of the different delineable phosphitylated hydroxyl groups are determined on the basis of the integral obtained for the signal of the internal standard, that is present in the analysis sample at a concentration of 0.1 m, creating a signal at the interval ranging from 144.5 ppm to 145.3 ppm. The area underneath the peak related to the internal standard is set to a value of 1.0 during peak integration within the standard processing of the crude NMR data, allowing for determining abundances using simple rule-of-proportion mathematics under consideration of the accurate weight of the sample used for this analysis. The analysis is run in triplicate, and final values are obtained as the standard average.
Method of Measuring Hydrolysable Ester Content:
The total ester content of the lignin can be determined by subjecting the lignin to alkaline hydrolysis conditions: Ca. 500 mg of lignin are dissolved in an excess of 1 M sodium hydroxide solution and heated to temperatures of above 70-80° C. for 12 h. The lignin is subsequently precipitated by acidifying the reaction mixture, isolated and freeze-dried.
Ca. 30 mg of the lignin are accurately weighed in a volumetric flask and suspended in 400 μL of the above prepared solvent solution. One hundred microliters of the internal standard solution are added, followed by 100 μL of 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane (Cl-TMDP). The flask is tightly closed, and the mixture is stirred for 120 min at ambient temperature. 31P NMR spectra are recorded using suitable equipment under the conditions reported above for the determination of aliphatic and aromatic hydroxyl contents. Quantification of the acid content is done on the basis of the signal intensities at the characteristic shift regions (in ppm) using a tailor-made table calculation referring to the signal of the internal standard. Abundances are typically given in mmol/g. The ester content is obtained as the difference in the abundances of acid groups, aliphatic hydroxyl groups, and aromatic hydroxyl groups found in untreated vs. the lignin treated with sodium hydroxide as outlined above. The analysis is run in triplicate, and final values are obtained as the standard average.
Method of Measuring Double Bond Content of Starting Lignins:
Lignin oligomers are acetylated in pyridine/acetic anhydride (V/V=1:1) at 50° C. for 48 h. Ethanol was added, and the volatiles were removed in vacuo; the procedure was repeated twice. Then, toluene was added, and the volatiles were quickly removed in vacuo, this was repeated twice, as well. Finally, chloroform was added, and the volatiles were removed in vacuo; again, this was repeated twice. The solid was then dried overnight in vacuo.
Measurements: All spectra were acquired at 303 K with a Bruker Avance 600 spectrometer equipped with a cryoprobe. The sample consisted of 80 mg of acetylated lignin dissolved in 600 μL of deuterated dimethylsulfoxide (DMSO-d6). A matrix consisting of 400×2048 points was obtained in eight scans. Either QQ-HSQC measurements or HSQC0 measurements are performed. QQ-HSQC measurements were performed in accordance with the original reference [D. J. Peterson, N. M. Loening, Magn. Reson. Chem. 2007, 45, 937-941.] as reported before [C. Crestini, F. Melone, M. Sette, R. Saladino, Biomacromolecules 2011, 12, 3928-3935; M. Sette, R. Wechselberger, C. Crestini, Chem. Eur. J. 2011, 17, 9529-9535]. In the HSQC0-related measurements, the second and third HSQC were obtained as repetitions of the basic HSQC scheme, according to the published procedure [K. Hu, W. M. Westler, J. L. Markley, J. Am. Chem. Soc. 2011, 133, 1662-1665; M. Sette, H. Lange, C. Crestini, Comput. Struct. Biotechnol. J. 2013, 6, e201303016].
Data processing: NMR data were processed with MestreNova (Version 8.1.1, Mestrelab Research) by using a 60°-shifted square sine-bell apodisation window; after Fourier transformation and phase correction a baseline correction was applied in both dimensions. The final matrix consisted of 1024×1024 points, and cross-peaks were integrated with the same software that allows the typical shape of peaks present in the spectrum to be taken into account. Extrapolations based on the values of the volumes of the peaks of interest of the three consecutive HSQC measurements were performed using MS Excel 2010, to yield the volumes of the different peaks for quantitative analyses.
Double bond containing structural units apart from aromatic structures in the lignin backbone are expressed in a generic double bond-equivalent for a given lignin.
How to Functionalise the Starting Lignin with Vinylic Reactants:
In the following, the term ‘lignin’ refers to all lignins covered by the definitions outlined in this document.
In the following, the term ‘vinylic reactants’ stands exemplary for all monomeric, oligomeric and polymeric molecules that i) exhibit at least one double bond equivalent in their structure, and that ii) were, in any case apart from monomeric substances, obtained by polymerisation of double bond-containing monomers.
In the following, radical starters can also be enzymes, recruited preferentially but not exclusively from the classes of laccases and lipoxygenases.
In the following, solvents can be organic solvents or aqueous solutions containing salts necessary for creating suitable environments for enzymes.
Depending on the choice of radical starter, and depending on the degree of control that is desired in the radical polymerisation reactions underlying the functionalisation of lignin with vinylic reactants, the temperatures for the reactions are chosen.
Example Reaction:
In a typical set-up, acrylic acid (x mg) is mixed with wheat straw biolignin (y mg), in 10 mL of toluene. Azobisisobutyronitril (AIBN) (100 mg) is added as radical starter and the reaction is stirred at 80° C. Once the reaction is finished after 12 h, the solvent is removed under reduced pressure to yield the newly formed lignin-vinyl species co-polymer. In case of enzymatically triggered reactions, enzymes and buffer salts are separated from the newly formed lignin-vinyl species hybrid by a suitable form of washing or dialysis.
How to Characterise and Quantify Functionalisation Content:
In the following, the term ‘lignin’ refers to all lignins covered by the definitions outlined in this document.
In the following, the term ‘vinylic reactants’ stands exemplary for all monomeric, oligomeric and polymeric molecules that i) exhibit at least one double bond equivalent in their structure, and that ii) were, in any case apart from monomeric substances, obtained by polymerisation of double bond-containing monomers.
Evaluation of Bonding Type:
Bonds between lignin starting materials and vinylic reactants are preferentially but eventually not exclusively formed between the double bond equivalent of the lignin substrate and the double bonds in the vinylic reactants. Bonding patterns and preferred bonding sites are determined and quantitatively estimated via quantitative two-dimensional NMR spectroscopy in form of quantitative HSQC measurements on the novel lignin-vinyl species hybrids after permethylating them using diazomethane as methylating reagent under standard textbook conditions. Quantitative HSQCs were obtained according to above mentioned experimental specifications in form of QQ-HSQC measurements or HSQC0 measurements.
Quantification of Vinylic Reactant in Novel Lignin-Vinyl Species Hybrids:
Novel lignin-vinyl species hybrids are permethylated using diazomethane as methylating reagent under standard textbook conditions. ca. 50 mg of permethylated hybrids are weighted exactly and dissolved in 600 μL deuterated dimethylsulfoxide (DMSO-d6), mixed with 2 mg of chromium acetylacetonate and an exact amount of ca. 3 mg of trioxane as internal standard. This mixture is subjected to quantitative 13C NMR spectroscopy. Quantification is based on the relative intensities of the signals stemming from carbon atoms in the lignin backbone and the grafted vinyl reactants with respect to the internal standard trioxane. Functional group contents are expressed in the lignin content of the novel hybrid material in % (m/m) lignin.
Emollient:
Suitable emollients are silicon based emollients. Silicone-based emollients are organo-silicone based polymers with repeating siloxane (Si 0) units. Silicone-based emollients of the present invention are hydrophobic and exist in a wide range of molecular weights. They include linear, cyclic and crosslinked varieties. Silicone oils are generally chemically inert and usually have a high flash point. Due to their low surface tension, silicone oils are easily spreadable and have high surface activity. Examples of silicon oil include: Cyclomethicones, Dimethicones, Phenyl-modified silicones, Alkyl-modified silicones, Silicones resins, Silica. Other emollients useful in the present invention can be unsaturated esters or fatty esters. Examples of unsaturated esters or fatty esters of the present invention include: Caprylic Capric Triglycerides in combination with Bis-PEG/PPG-1 6/16 PEG/PPG-16/16 Dimethicone and C12-C15 Alkylbenzoate.
The basic reference of the evaluation of surface tension, polarity, viscosity and spreadability of emollient can be found under Dietz, T., Basic properties of cosmetic oils and their relevance to emulsion preparations. SOFW-Journal, July 1999, pages 1-7.
Humectant:
A humectant is a hygroscopic substance used to keep things moist. Typically, it is often a molecule with several hydrophilic groups, most often hydroxyl groups; however, amines and carboxyl groups, sometimes esterified, can be encountered as well (its affinity to form hydrogen bonds with molecules of water is the crucial trait). A humectant typically attracts and retains the moisture in the air nearby via absorption, drawing the water vapour into and/or beneath the organism/object's surface.
Suitable humectants include: Propylene glycol, hexylene glycol, and butylene glycol, Glyceryl triacetate, Neoagarobiose, Sugar alcohols (sugar polyols) such as glycerol, sorbitol, xylitol, maltitol, Polymeric polyols such as polydextrose, Quillaia, Urea, Aloe vera gel, MP diol, Alpha hydroxy acids such as lactic acid, Honey, Lithium chloride
Emulsifier:
An emulsifier generally helps disperse and suspend a discontinuous phase within a continuous phase in an oil-in-water emulsion. A wide variety of conventional emulsifiers are suitable for use herein. Suitable emulsifiers include: hydrophobically-modified cross-linked polyacrylate polymers and copolymers, polyacrylamide polymers and copolymers, and polyacryloyldimethyl taurates. More preferred examples of the emulsifiers include: acrylates/C10-30 alkyl acrylate cross-polymer having tradenames PemulenTM TR-1, PemulenTM TR-2 (all available from Lubrizol); acrylates/steareth-20 methacrylate copolymer with tradename ACRYSOLTM 22 (from Rohm and Hass); polyacrylamide with tradename SEPIGEL 305 (from Seppic).
