Description

  The present invention relates to a thickener composition, a method for producing the same, and a method for thickening, and more specifically, a thickener composition having improved handling properties and workability while maintaining thickening performance, and a method for producing the same, and The present invention relates to a thickening method using the thickener composition.

  Liquid detergent compositions such as hair shampoos and body cleaners are required to have properties such as foamability, detergency, fingering, rinsing properties and texture. In recent years, the habit of daily bathing and washing has become established, and the detergency is not as important as before, but rather it is required to be hypoallergenic.

  In order to realize such a requirement, a mild surfactant is often used. However, many of the low-irritant surfactants have the property of being hard to thicken, and development of an effective thickener or thickening method for a low-irritant liquid detergent composition is strongly desired. It was.

  In order to solve the above problems, various polyether type thickeners have been developed and commercialized. This group of thickeners is preferred because it has high thickening performance, the thickened material exhibits Newtonian viscosity, and does not deteriorate low temperature stability. However, these thickeners have a problem in workability, for example, it takes a long time to dissolve in the liquid detergent composition.

  In order to solve this problem, a thickener composition containing a polyether derivative, a low molecular weight alkylene glycol alkyl ether and water has been proposed (Patent Document 1). Since the solid polyether-type thickener becomes liquid, it can be easily dissolved or dispersed in the liquid to be thickened, so that the handling of the thickener composition is facilitated and workability is improved. Are listed.

  However, the inclusion of a low molecular weight alkylene glycol alkyl ether and water results in a relatively reduced thickening performance because the content of the polyether type thickener is reduced. In addition, low molecular weight alkylene glycol alkyl ethers are rarely used in hair shampoos, body cleaners, household cleaners, and the like because of safety issues. Prescription may be restricted.

  Also disclosed is a method for producing a detergent composition by adding a premixed polyether-type thickener and fatty acid diethanolamide and / or polyoxyethylene alkyl ether to an aqueous surfactant solution (patent). Reference 2). It is described that the time for uniform dissolution can be shortened by premixing in this way.

  However, although the above mixture has sufficient thickening performance, it has a tendency to become a sticky solid at room temperature, so it is difficult to process into any shape of flake, bead or pellet. The handling properties during weighing and preparation work were not sufficient, such as sticking to each other during storage. In addition, when the premix is added to the liquid detergent composition to increase the viscosity, the solidified premix is reheated and added after melting, or the premix is prepared and not solidified to continue with the liquid detergent. It is not always satisfactory in workability and productivity because a complicated process such as addition to the composition is required.

By adopting these shapes, it is possible to prevent the thickener composition from floating on the liquid surface or remaining on the foam when blended into the liquid detergent composition.

  As a method for producing a thickener composition having these shapes, for example, a polyether type thickener and a monoalkanolamide are sufficiently stirred and mixed while being melted at a temperature higher than the melting point, and then a flaker, a letterer, A method using a known granulating apparatus such as a Malmerizer is exemplified.

  The size of the flake-like, pellet-like or bead-like thickener composition is not particularly limited, but it is a liquid cleaning agent from the viewpoint of suppressing dust generation, preventing floating on the liquid surface or remaining on the foam. It is preferable to balance the size in consideration of solubility or dispersibility in an aqueous medium such as a composition. Specifically, in the case of flakes, the thickness is 0.5 to 2 mm, the length is about 3 to 10 mm, in the case of pellets, the major axis is 3 to 10 mm, the maximum thickness is about 0.5 to 3 mm, and the diameter is in the case of beads. About 1-4 mm is preferable.

  When the size of the thickener composition is too small, it tends to generate dust, float on the liquid surface, or remain on the foam. On the other hand, if it is too large, it tends to be difficult to disperse smoothly and finely in an aqueous medium such as a liquid detergent composition.

  When the thickener composition of the present invention is used in an aqueous medium such as a liquid detergent composition, the liquid temperature of the aqueous medium before thickening is set to 60 ° C. or higher, whereby the thickener composition is It becomes possible to dissolve or disperse more rapidly.

  The thickener composition of the present invention is a thickener for various liquid media such as oily media such as natural oils, synthetic oils and oily paints, aqueous paints, aqueous emulsion paints, water, aqueous electrolytes, aqueous media such as water-soluble organic solvents and the like. Can be used as an agent. Especially, it is suitable for the thickening of an aqueous medium, and the remarkable thickening effect is exhibited especially with respect to a liquid detergent composition.

  There is no restriction | limiting in particular as a liquid detergent composition which concerns on this invention, A well-known liquid detergent composition etc. are used. Specific examples include hair shampoos, body cleaners, pet shampoos, kitchen detergents, and residential cleaners.

  Examples of the surfactant used in these liquid detergent compositions include anionic surfactants, amphoteric surfactants, nonionic surfactants, and cationic surfactants. These can be used individually or in combination of two or more.

  Specifically, alkyl sulfate, alkyl ether sulfate, fatty acid amide ether sulfate, alkane sulfonate, α-olefin sulfonate, sulfosuccinate ester salt, alkyl ether carboxylate, acylated amino acid salt, fatty acid salt Anionic surfactants such as alkylbenzene sulfonates and alkyl phosphate esters, amphoteric surfactants such as alkylbetaines, fatty acid amidopropylbetaines, hydroxysulfobetaines, imidazolinium betaines (amide amino acid type), amine oxides, Nonionic surfactants such as polyoxyalkylene alkyl ethers, fatty acid alkanolamides, alkyl polyglycosides, sorbitan fatty acid esters, polyoxyalkylenated sorbitan fatty acid esters, polyoxyalkylenated hydrogenated castor oil Alkyl methyl ammonium salt, cationic surfactants such as alkyl benzalkonium salts are exemplified. These can be used individually or in combination of two or more.

  The thickener composition of the present invention is used, for example, in combination with an anionic surfactant in combination with an amphoteric surfactant and / or a fatty acid alkanolamide rather than when used for a single surfactant aqueous solution. When used for the prepared aqueous surfactant solution, the thickening performance becomes remarkable, and a desired viscosity can be obtained with a relatively small amount of use.

  The addition amount of the thickener composition of the present invention is not particularly limited as long as the object effect of the present invention is obtained, but is usually 0.01 to 100 parts of an aqueous medium such as a liquid detergent composition. 10 parts by weight, preferably 0.05 to 5 parts by weight. When the added amount exceeds 5 parts by weight, a thickening effect can be obtained, but the required dissolution time tends to be exceeded. Moreover, when the addition amount is less than 0.05 parts by weight, the effect of thickening is reduced, and the desired viscosity may not be obtained.

The method for preparing the thickener composition of the present invention is not particularly limited as long as the effects of the present invention are achieved. For example, the polyether type thickener and monoalkanolamide according to the present invention are higher than their melting points. Examples thereof include a method of sufficiently stirring and mixing while melting at a temperature, and a method of mixing and molding fine pulverized monoalkanolamide in the same manner as a polyether type thickener previously finely pulverized.
Preferably, a method in which the polyether type thickener according to the present invention and the monoalkanolamide are mixed with sufficient stirring while melting at a temperature higher than the melting point thereof is recommended. This manufacturing method does not require a special manufacturing apparatus, is easy even in the form of flakes, pellets, or beads, and the effects of the present invention are more easily obtained.

  The thickener composition of the present invention may be added with other additives within a range not impairing the object effect of the present invention.

  Examples thereof include fatty acid dialkanolamide, polyoxyalkylene fatty acid alkanolamide, low HLB polyoxyalkylene alkyl ether, and fatty acid. These are generally compatible with the thickener composition of the present invention, and often contribute to the thickening of the liquid detergent composition.
