Abstract

PURPOSE:To obtain a powdery perfume having excellent stabilities in a storage for a long period of time, especially even in a case of strong alkali, by solubilizing or emulsifying a liquid perfume into an aqueous solution of surfactant, mixing resultant solution or emulsion with a substance capable of forming water of crystallization and powderizing. CONSTITUTION:A liquid perfume is solubilized or emulsified into an aqueous solution of preferably anionic and/or nonionic surfactant, mixed with an anbydrous or partially containing water of crystallization inorganic material (e.g., sodium sulfate, magnesium sulfate, sodium orthophosphate, sodium pyrophosphate, sodium tripolyphosphate, sodium borate) and/or organic material (e.g., sodium citrate) which is capable of forming water of crystallization and then powdered.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of powderizing a liquid perfume and a detergent composition containing the powder perfume obtained by the method.

[Prior Art and Problems to be Solved by the Invention] Generally, perfumes are in liquid form (of course, there are also solid perfumes such as camphor) and are used for various purposes. One of its uses is as a component of detergents for clothing, tableware, homes, etc., and is used for purposes such as masking raw material odors and providing comfort to users during use. At this time, if the cleaning agent is liquid, it can be easily added, but
No special efforts have been made for powder, granular, or solid detergent systems. - For boat fishing, liquid fragrances are sprayed onto powder systems, or mixed with some components of cleaning agents in advance and solidified into powder, which is added as a so-called master powder. However, when such a powdery fragrance is added, stability may become a problem especially in the case of long-term storage or in cases where the system is particularly alkaline.

[Means for solving problems]

As a result of intensive studies to solve these problems, the present inventors found that after emulsifying or solubilizing the fragrance with an aqueous surfactant solution, a finely powdered organic or inorganic compound capable of removing crystallization water is added and mixed. It has been found that this problem can be solved by powdering or granulating the powder.

That is, the present invention provides a method for pulverizing a liquid fragrance,
After solubilizing, emulsifying, or dispersing a liquid fragrance with an aqueous surfactant solution, an anhydrous organic or inorganic compound capable of removing crystallization water or an organic or inorganic compound having some crystallization water is added and mixed to powder or granulate it. The present invention aims to provide a method for powderizing a liquid fragrance characterized by the following, and a detergent composition containing the powdered fragrance obtained by the method.

As the surfactant used in the powdering method of the present invention, nonionic surfactants and anionic surfactants are best, but other surfactants can also be used if necessary.

As a nonionic surfactant, polyoxyethylene glycol ether of a long chain alcohol having an alkyl group having 8 to 22 carbon atoms (3 to 30 moles of ethylene oxide added) is used.
, polyoxyethylene glycol ether of alkylphenol having an alkyl group having 8 to 22 carbon atoms (3 to 30 moles of ethylene oxide added), polyoxyethylene glycol ester of fatty acid having an alkyl group having 8 to 22 carbon atoms (adding ethylene oxide) number of moles 3 to 30),
Examples include glycerin, propylene glycol ester, or sorbitan ester of a fatty acid having an alkyl group having 8 to 22 carbon atoms.

When solubilizing, emulsifying or dispersing fragrances, water 30-90%
The content can be arbitrarily adjusted within the range of 5% to 60% by weight of surfactant, and 5% to 50% by weight of fragrance. When solubilizing, emulsifying, or dispersing, the fragrance is generally added gradually while stirring the active agent aqueous solution.

In carrying out the present invention, the solubilization, emulsification, or dispersion system of the fragrance is preferably one with excellent storage stability, but since the next powdering step is immediately carried out after preparation, stability is particularly important. It can be used regardless. In some cases, it may be used as a mechanically forced dispersion system using a homomixer or the like.

The solubilized, emulsified, or dispersion solution of the fragrance thus obtained preferably has a particle size of 1000 μm or less, more preferably 40 μm or less, and is mixed with a finely powdered inorganic salt or organic salt capable of absorbing crystallization water. It is powdered by

Inorganic salts that can remove crystal water include magnesium sulfate,
Sodium sulfate, sodium orthophosphate, sodium pyrophosphate, sodium tripolyphosphate, anhydrous sand,
Examples include metacide, sodium carbonate, etc. In addition, examples of organic salts that can remove water of crystallization include sodium citrate,
Examples include sodium tartrate.

The method of mixing with an inorganic salt or an organic salt capable of removing water of crystallization includes solubilizing, emulsifying, or dispersing the fragrance in a fluidized bed of a substantially anhydrous finely powdered inorganic salt or an organic salt. More preferably, the system is sprayed in fine powder form. or a substantially anhydrous finely powdered inorganic salt that is stirred and mixed;
Alternatively, a solubilized, emulsified, or dispersed fragrance may be gradually added to an organic salt system to form a powder.

The powdered fragrance thus obtained is used by adding it to a powdered detergent system.

The cleaning composition of the present invention contains 10 to 60 cleaning active agents selected from anionic active agents, nonionic active agents, amphoteric active agents, and cationic active agents, or a mixture of two or more of these active agents. 0.1 to 5% by weight of a powdered fragrance obtained by pulverizing a liquid fragrance by the above method is added to a powder, granular, or solid detergent composition containing 30 to 80% by weight of detergent builder. Ru.

The detergent composition used in the present invention may further contain other components commonly used in detergents, if necessary.
