Abstract

To provide a viscous composition having excellent viscosity and stability even while containing hydroxyethyl cellulose and an ionic surfactant.

Description

Viscous composition

The present disclosure relates to a viscous composition and the like, and more particularly to a viscous composition containing cellulose nanocrystals. The contents of all documents described in this specification are incorporated herein by reference.

Polymer thickeners are widely used for preparing viscous compositions in various fields, such as cosmetics and food fields.

However, the thickening effect of the polymer thickener may be reduced by the ionic surfactant. In addition, the composition containing the polymer thickener and the ionic surfactant may have poor stability. For example, hydroxyethyl cellulose (HEC) is also a component widely used as a polymer thickener, but it contains hydroxyethyl cellulose and an ionic surfactant because its thickening effect is reduced by the ionic surfactant. However, it has not been easy to prepare a viscous composition having excellent viscosity and stability.

Hereinafter, each embodiment included in the present disclosure will be described in more detail. The present disclosure preferably includes, but is not limited to, a viscous composition, a method for producing the same, and the like, and the present disclosure includes all disclosed in the present specification and recognized by those skilled in the art.

The viscous composition included in the present disclosure contains cellulose nanocrystals, hydroxyethyl cellulose, and water. The viscous composition included in the present disclosure may be referred to as "the composition of the present disclosure". The compositions of the present disclosure also include viscous compositions containing ionic surfactants in addition to cellulose nanocrystals, hydroxyethyl cellulose, and water. Among the compositions of the present disclosure, those containing an ionic surfactant are referred to as "the ionic surfactant-containing composition of the present disclosure", and those containing no ionic surfactant are referred to as "the ionic surfactant of the present disclosure". It may be referred to as "agent-free composition".

Cellulose nanocrystal is a kind of nanocellulose. In particular, examples of nanocellulose made from wood or the like include cellulose nanofibers (CNF) and cellulose nanocrystals (CNC). Among nanocellulose, those having a relatively long length are called cellulose nanofibers (CNF), and those having a relatively short length are called cellulose nanocrystals (CNC). Although not limited, nanocellulose having a length of about 5 to 10 μm or more is often referred to as cellulose nanofiber (CNF), and those having a length shorter than CNF are often referred to as cellulose nanocrystal (CNC). It seems.

As the CNC used in the composition of the present disclosure, for example, the nanocrystalline cellulose described in Patent Document 1 (Japanese Patent Laid-Open No. 2012-531478) can be preferably used.

Cellulose is a natural polymer material that constitutes woody biomass and agricultural biomass together with hemicellulose and lignin. It is a homopolymer of repeating units of glucose linked by β-1,4-glycosidic bonds. Cellulose is formed linearly by β-1,4-glycosidic bonds, and they interact strongly with each other through hydrogen bonds. Due to its regular structure and strong hydrogen bonds, the cellulose polymer is highly crystalline and aggregates to form partial structures and microfibrils. Then, the microfibrils aggregate to form cellulosic fibers.

Cellulose purified from woody biomass or agricultural biomass can be disrupted or produced on a large scale by bacterial processes. When a cellulosic material is composed of nano-sized fibers and the properties of the material are determined by the structure of the nanofibers, these polymers are referred to as nanocellulose. In general, nanocellulose is a rod-shaped fibril with a length / diameter ratio of approximately 20-200.

Generally, the preparation of nanocellulose can be explained by two methods. In the first method, nanocellulose can be prepared, for example, from chemical pulp of wood fiber or agricultural fiber by removing the amorphous region mainly by acid hydrolysis to produce nano-sized fibril. Cellulose nanocrystals can be formed and stabilized in an aqueous suspension by, for example, sonicating the fibrils or passing them through a high shear microfluidizer.

The second method is mainly physical processing. Bundles of microfibrils, usually tens of nanometers (nm) to several micrometer (μm) in diameter, called cellulose microfibrils or microfibrillated cellulose, are produced by using high pressure homogenization and grinding. .. Steps with high intensity sonication have also been used to isolate fibril from natural cellulose fibers. High-intensity ultrasound can generate very strong mechanical vibration forces, which allows the separation of cellulose fibrils from biomass. This method produces microfibrillated cellulose having a diameter of less than about 60 nm, more preferably about 4 nm to about 15 nm, and a length of less than 1000 nm. Microfibrillated cellulose can also be subjected to, for example, further chemical, enzymatic and / or mechanical treatments. The microfibrillated cellulose can also be used as a cellulose nanocrystal.

In other words, the cellulose nanocrystals used in the compositions of the present disclosure are, for example, by removing amorphous regions from pulp by acid hydrolysis, or by physical treatment such as high pressure treatment, pulverization treatment, and ultrasonic treatment. It can be appropriately prepared by treatment (and even by using these in combination).

Further, the cellulose portion of the cellulose nanocrystal used in the composition of the present disclosure may be a cellulose sulfate (cellulose sulfate). As the salt, a sodium salt is preferable. That is, the cellulose portion of the cellulose nanocrystal used in the composition of the present disclosure may be cellulose sulfate sodium sulfate.

Therefore, in the present disclosure, the wording "cellulose nanocrystal" or "CNC" indicates a crystal of nano-sized cellulose, and the cellulose may be an unmodified form or a modified form. As described above, as the cellulose modified product, for example, cellulose sulfate (particularly sodium cellulose sulfate) is preferably mentioned.

Although not particularly limited, examples of the CNC include nanocellulose having a thickness of about 1 to 100 nm and a length of about 50 to 500 nm. The upper or lower limit of the thickness range (1 to 100 nm) is, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, and so on. 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, It may be 93, 94, 95, 96, 97, 98, or 99 nm.

Further, although not particularly limited, HEC is a compound in which the OH group of cellulose is OR (R indicates H or CH ₂ CH ₂ OH), and is contained in the composition of the present disclosure. In HEC (including non-crosslinked HEC and crosslinked HEC), a group other than H or CH ₂ CH ₂ OH may be present as R of the OR, but it is preferable that no hydrophobic group is present as R. For example, as the R, an alkyl group, particularly a linear chain having 6 to 20 carbon atoms (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20) or Those having a branched chain alkyl group (more specifically, for example, a cetyl group) may be used, but it is preferable not to use them.

The composition of the present disclosure contains water as a solvent. Further, a solvent other than water may be further contained as long as the effect of the composition of the present disclosure is not impaired. Examples of the solvent other than water include water-soluble solvents, and for example, water-soluble organic solvents are preferable. Examples of the water-soluble organic solvent include monohydric or divalent alkyl alcohols having 1 to 6 carbon atoms (1, 2, 3, 4, 5, or 6), and more specifically, for example. Examples thereof include ethanol and butylene glycol.

Further, in the composition of the present disclosure, the value of the storage elastic modulus (G') is larger than the value of the loss elastic modulus (G'') (that is, the storage elastic modulus G'> the loss elastic modulus G''). Those are preferable. In other words, the composition of the present disclosure preferably has a loss tangent (tan δ) of less than 1 (that is, tan δ <1). The loss tangent (tan δ) is the ratio (G ″ / G ′) of the storage elastic modulus (G ′) and the loss elastic modulus (G ″), and is used as one of the indexes of the viscoelastic property. The larger the value of the loss tangent, the smaller the elastic modulus. For example, the loss tangent is used as an index of sol and gel, and usually tan δ> 1 is sol and tan δ <1 is gel.

The values of the storage elastic modulus G ′ and the loss elastic modulus G ″ can be measured at 25 ° C. using a viscoelasticity measuring device (leometer). More specifically, after confirming the linear region by measuring the strain dispersion at 1 Hz, an appropriate distortion is selected within the range of the linear region, and the frequency dispersion at 25 ° C. (frequency: 0.1 rad / s to 100 rad / s). And observe the magnitude relationship between G'and G''.

In the composition of the present disclosure, the storage elastic modulus G'and the loss elastic modulus G'' obtained by frequency dispersion measurement have a magnitude relationship of the storage elastic modulus G in the entire range of frequency: 0.1 rad / s to 100 rad / s.
