Definitions

  • the present invention relates to a gelatinous or pasty detergent composition contained in a container.
  • a powdery detergent is usually bagged or boxed, but it causes problems in handling due to its low apparent specific gravity and it makes transportation cost comparatively high.
  • the detergent components essentially include a builder because of functional reason and the builder is in a solid form. Accordingly the liquid detergent has to be in a form of aqueous solution in which the concentration of effective components is about 50 % or less (% means % by weight in this specification unless otherwise specified) so that a uniform composition is obtained, and due to such a restriction there are problems in handling so far.
  • An object of the present invention is to solve the above-mentioned problem and to provide a detergent composition which is unvoluminous and easy to handle and which has a less tendency to change in quality with a passage of time.
  • a detergent composition contained in a tube or a pumping container which is a gelatinous or pasty detergent composition including homogeneous or dispersed mixture of nonionic surface active agent having fluidity at room temperature and at least one member selected from a group consisting of organic sulfonic acid salts and organic sulfuric ester salts.
  • a nonionic surface active agent having fluidity at room temperature used in the present invention is a nonionic surface active agent preferably having a viscosity of about 50 to about 2000 poise at room temperature (15° to 25°C).
  • any fluidic nonionic surface active agent in accordance with the purposed application and the like of the detergent composition can be selected and used without any limitation as far as it is commonly used for the purpose of emulsification, dispersion, osmosis, washing, solubilization or the like.
  • preferable examples thereof are, for instance, adduct of alkylene oxide such as ethylene oxide, propylene oxide and butylene oxide to active hydrogen compound having 8 to 20 average carbon atoms such as alcohol, alkylphenol, fatty acid and alkylamine; ester of sorbitan, sucrose or the like with fatty acid having 8 or more carbon atoms; and the like.
  • alkylene oxide such as ethylene oxide, propylene oxide and butylene oxide
  • active hydrogen compound having 8 to 20 average carbon atoms such as alcohol, alkylphenol, fatty acid and alkylamine
  • ester of sorbitan sucrose or the like with fatty acid having 8 or more carbon atoms
  • any one kind may be used alone or alternatively two or more kinds may be used together.
  • Preferable content of the nonionic surface active agent in the detergent composition is 10 to 60 % and more preferably 25 to 45 %.
  • the content lower than 10 % increases the apparent viscosity of gelatinized product and consequently tends to make it difficult to squeeze the detergent composition out of a tube or a pumping container.
  • the content higher than 60 % tends to cause a separation at high temperatures.
  • the organic sulfonic acid salt and/or organic sulfuric ester salt is a component used as a main component of the detergent agent.
  • any organic sulfonic acid salt and/or organic sulfuric ester salt in accordance with the purposed application and the like of the detergent composition can be selected and used without any limitation as far as it is commonly used in a detergent composition for clothes or the like.
  • organic sulfonic acid salt such as alkylbenzenesulfonic acid salt, dialkylbenzenesulfonic acid salt, naphthalenesulfonic acid salt and ⁇ -­olefinesulfonic acid salt
  • organic sulfuric ester salt such as sulfuric ester salt of alcohol and sulfuric ester salt of adduct of ethylene oxide to alcohol
  • any one kind may be used alone or alternatively two or more kinds can be used together.
  • a use of organic sulfonic acid salt provides an advantageous feature that there can be obtained a detergent composition having improved detergency while a use of organic sulfuric ester salt provides another advantageous feature that there can be obtained a well biodegradable and highly safe detergent composition.
  • Preferable content of the organic sulfonic acid salt and/or the organic sulfuric ester salt in the detergent composition is 10 to 60 % and more preferably 25 to 45 %.
  • the content lower than 10 % tends to cause insufficient detergency effect.
  • the content higher than 60 % tends to provide excessively high viscosity of gelatinized product and consequently it tends to be difficult to obtain soft gel.
  • the detergent composition contained in a container in accordance with the present invention may optionally include as occasion demands other additives commonly used as additives for a detergent composition such as surface active agent other than the nonionic surface active agent, the organic sulfonic acid salt or the organic sulfuric ester salt (hereinafter referred to as other surface active agent); builder; enzymes; fluorescent material; peroxide; perfume; solvent; and the like.
  • Examples of the above-mentioned other surface active agent are, for instance, soaps such as sodium oleate, sodium laurate, potassium oleate and sodium stearate; amphoteric surface active agent such as AMOGEN K (alkylbetaine amphoteric surface active agent available from DAI-ICHI KOGYO SEIYAKU CO., LTD.); and the like.

  • Preferable amount of enzymes in the detergent composition is normally 0.5 to 2.0 %.
  • fluorescent material examples include 2-(stilphenyl) naphthothiazole derivative, 4,4′-bis(triazole-2-yl) stilbene derivative, bis(triazinylamino) stilbene disulfonic acid derivative, 4,4′-bis(2-sulfostyryl) biphenyl salt, 4,4′-bis(4-chloro-­3-sulfostyryl) biphenyl salt and the like.
  • Preferable amount of the fluorescent material in the detergent composition is normally 1.0 to 4.0 %.
  • peroxide examples include sodium percarbonate and the like.
  • Preferable amount of the peroxide in the detergent composition is normally 1.0 to 4.0 %.
  • perfume, coloring agent and the like may also be included in the detergent composition and preferable amount thereof in the detergent composition is normally 1.0 to 4.0 %.
  • the solvent for example there can be used, as the occasion may demand, water, glyceline, ethylene glycol, diethylene glycol monobutyl ether and the like.
  • the detergent composition to be contained in a tube or a pumping container in accordance with the present invention is a gelatinous or pasty composition including homogeneous or dispersed mixture of nonionic surface active agent having fluidity at room temperature and at least one member selected from a group consisting of organic sulfonic acid salts and organic sulfuric ester salts.

  • the pumping container 3 illustrated in Fig. 3 is preferably used.
  • a preferable preparing process involves a step of neutralization of organic sulfonic acid and/or organic sulfuric ester in the presence of nonionic surface active agent (in this neutralizing step the nonionic surface active agent exhibits liquid behavior), and then there is prepared a homogeneous or dispersed mixture of nonionic surface active agent having fluidity at room temperature and at least one member selected from a group consisting of organic sulfonic acid salts and organic sulfuric ester salts. Thereafter, other optional components are added as occasion demands in accordance with a common procedure to the obtained mixture.
