Description

  The present invention relates to a cleaning composition that can exhibit an excellent feeling of use in each temperature range.

  Many gel detergents have been proposed, but have a so-called temperature dependency that the viscosity increases at a low temperature and decreases at a high temperature.

Regarding this viscosity, in order to enhance long-term stability, a combination of a long-chain acylamino acid salt type anionic surfactant, xanthan gum and a nonionic surfactant in a specific ratio has been proposed ( For example, see Patent Document 1.)
JP-A-11-323388

  However, even if the long-term stability of the viscosity is improved like the above-mentioned conventional gel-like cleaning agent, the problem of temperature dependence has not been solved, and it is used by filling a tube-type container or a dispenser container. In such a case, the viscosity becomes high at low temperatures, making it difficult to take out, and at high temperatures, the viscosity becomes low and dripping occurs.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a cleaning composition capable of obtaining excellent usability without being influenced by temperature as well as long-term stability. .

  The detergent composition of the present invention for solving the above problems is a blend of (a) a fatty acid alkali salt and (b) polyethylene polypropylene pentaerythritol ether and / or (c) polyoxypropylene sorbitol ether.

  (A) Fatty acid alkali salts include sodium, potassium, calcium, magnesium, ammonium, and triethanolamine salts of fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, and oleic acid And alkali salts such as tripropanolamine salt. Specific examples of suitable fatty acid alkali salts include lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, sodium or potassium isostearic acid alone or in combination.

  These may be used alone or in combination of two or more.

  In the present invention, the content of the (a) fatty acid alkali salt in the composition is preferably 5 to 40% by weight. If this content is less than 5% by weight, foaming and detergency are inferior. On the other hand, if it exceeds 40% by weight, the detergency becomes too strong, and a feeling of crispness is felt after use.

  The cleaning composition of the present invention contains at least (b) polyethylene polypropylene pentaerythritol ether and / or (c) polyoxypropylene sorbitol ether together with the fatty acid alkali salt as component (a). As a result, there is no difference in viscosity at each temperature (no temperature dependence), the viscosity is stable over time, and there is no problem with fluidity. Moreover, in use, it is excellent in usability and feeling of use, and it does not take time to wash off after use.

  In the present invention, the content of (b) polyethylene polypropylene pentaerythritol ether and / or (c) polyoxypropylene sorbitol ether in the composition is 0.01 to 10% by weight, more preferably 0.1 to 5% by weight. Is preferred. If the content is less than 0.01% by weight, the effect of stabilizing the viscosity over time cannot be obtained without temperature dependence. Conversely, if the content exceeds 10% by weight, the effect is saturated and other compositions are used. This is not preferable because the blending balance with the product cannot be maintained.

  Any one of these (b) polyethylene polypropylene pentaerythritol ethers and (c) polyoxypropylene sorbitol ethers may be used, or two may be mixed and used. When mixing and using two, a compounding ratio is not specifically limited, As long as the total amount of both compounding amounts is 0.01-10 weight% as above-mentioned, what is necessary is just.

  In addition to the above components, the cleaning composition of the present invention includes alcohols, polysaccharides, oils, protein derivatives, drugs, inorganic acids or salts thereof, organic acids or salts thereof, as long as the effects of the present invention are not impaired. In addition, antioxidants, ultraviolet absorbers, dyes, fragrances, and other various components that are generally blended into cleaning compositions may be included.

  The cleaning composition of the present invention can be prepared by mixing each of the above components with a solvent such as alcohol or water and heating and dissolving at a predetermined temperature.

  The cleaning composition thus obtained has no difference in viscosity at each temperature (no temperature dependence), the viscosity is stable over time, and there is no problem with fluidity. . Specifically, even when a severe temperature change (−5 ° C. to 40 ° C. in the examples) assumed in daily life is given from a temperature below freezing to a temperature equal to or higher than body temperature, the rate of change in viscosity (100− ( Viscosity after storage at 40 ° C. for 1 month / viscosity after storage at −5 ° C. for 1 month) × 100) can be less than 50%, and more preferably less than 30% when blended more preferably.

  Therefore, particularly when a tube-type container or a dispenser container is filled and used, an excellent effect is easily realized.

  In the case of a tube-type container, a viscosity of about 5000 to 300000 mPa · s is preferable, and in the case of a dispenser container, a viscosity of about 3000 to 30000 mPa · s is preferable, and each cleaning agent is within the range of these adaptive viscosities. The composition is prepared. And each container is designed according to the viscosity of each prepared cleaning composition.

  For example, in the case of a detergent composition prepared with a high adaptive viscosity in a tube-type container, the outlet of the tube-type container is usually formed to be large according to the adaptive viscosity prepared at a high level. The container itself is usually made soft. In such a situation, if it changes by 50% or more in the direction of decreasing the viscosity, it will cause dripping. Conversely, in the case of a detergent composition prepared with a low adaptive viscosity in a tube-type container, the outlet of the tube-type container is usually formed small in accordance with the low-adapted adaptive viscosity. The tube-type container itself is usually formed hard. In such a situation, if the content changes by 50% or more in the direction of increasing the viscosity, it becomes difficult to take out the contents. If the cleaning composition of the present invention is used in such a situation, even if there is a severe temperature change assumed in daily life, the change in viscosity can be suppressed to less than 50%, preferably less than 30%. Since it can do, the outstanding usability of each tube type container can be maintained.

  Similarly, in the case of a detergent composition prepared with a high adaptive viscosity in a dispenser container, the pump of the dispenser container is usually formed with a large diameter in accordance with the adaptive viscosity prepared high. In such a situation, if it changes by 50% or more in the direction of decreasing the viscosity, it will cause dripping. Conversely, in the case of a detergent composition prepared with a low adaptive viscosity in the dispenser container, the pump of the dispenser container should have a small diameter and a long stroke in accordance with the adaptive viscosity prepared low. Always. In such a situation, if the viscosity changes by 50% or more in the direction of increasing the viscosity, it becomes difficult to operate the pump and it becomes difficult to take out the contents. If the cleaning composition of the present invention is used in such a situation, even if there is a severe temperature change assumed in daily life, the change in viscosity can be suppressed to less than 50%, preferably less than 30%. Therefore, the excellent usability of each dispenser container can be maintained.

  In addition, since the production of the cleaning composition is carried out in a factory whose environment has been adjusted, when manufacturing cleaning products for winter cold regions with an average temperature of 5 ° C or lower and summer warm regions with an average temperature of 30 ° C or higher, this The composition of each component must be changed in consideration of such regions and seasons. However, in the case of the cleaning composition of the present invention, there is no great difference in viscosity at each temperature (no temperature dependence), so it is troublesome to change the composition of each component in consideration of the region and season. Otherwise, it can be easily manufactured with a common formulation.

  Furthermore, various cleaning agents in which a tube composition or a dispenser container is filled with the cleaning composition produced in this way are as described above in winter cold regions with an average temperature of 5 ° C. or lower, or with an average temperature of 30 ° C. or higher. It can be used with an excellent feeling of use without any problems even in summer warm regions. Therefore, even when the environment is not adjusted or when the environment changes with traveling or business trips, an excellent feeling of use can be obtained corresponding to any environment.

As described above, according to the cleaning composition of the present invention, the viscosity can be stabilized over time without causing a large difference in viscosity at each temperature. Further, even transparency of gel-type detergent compositions, without causing a large difference in viscosity at each temperature, over time it is possible to stabilize the viscosity. Therefore, excellent usability can be obtained regardless of the season and place.
