Abstract

PURPOSE:To obtain a powdery perfume having excellent preservation stability for a long period even under strong alkaline conditions, by gelatinizing a liquid perfume with an organic gelling agent, adding an inert inorganic or organic powder and powdering the resultant blend. CONSTITUTION:A liquid perfume is gelatinized with an organic gelling agent, such as alkaline metal salt of a di- or mono-long-chain alkyl phosphate, dibenzylidenesorbitol or N-acylamino acid alkylamide, and an inert inorganic powder, such as sodium sulfate, sodium carbonate or silica, or inert organic powder, such as polyvinyl chloride, sodium citrate or starch, is added to powder the resultant gel.

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.

[Conventional technology and its problems]

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, it can be easily added to liquid detergents, but no special efforts have been made for powder, granular, or solid detergent systems. Generally, a liquid fragrance is sprayed onto a powder system, or mixed in advance with some components of a cleaning agent, and then added as a powder or solidified product, a so-called master powder. However, when such powder-based fragrances are stored for a long period of time, stability may become a problem, especially when the system is highly alkaline.

[Means for solving problems]

As a result of intensive studies to solve these problems, the present inventors found that after gelling a fragrance with an organic gelling agent, an inert inorganic or organic powder was added to the fragrance and the gelling agent. 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, comprising:
A method for powdering a liquid fragrance, which comprises gelling a liquid fragrance with an organic gelling agent, and then adding an inert inorganic powder or an organic powder to powder it, and an anionic activator.
10 to 60% by weight of one type of cleaning activator selected from nonionic activators, amphoteric activators, and cationic activators, or a mixture of two or more of these activators, and 30 to 8% of detergent builder.
For a powdered, granular, or solid detergent composition containing 0% by weight, add 0.1 to 0.1% to
The object of the present invention is to provide a detergent composition containing 5% by weight.

In the powdering method of the present invention, it is necessary to first gel the liquid fragrance using an organic gelling agent, rather than simply powdering it with powder. Next, an inert inorganic or organic powder is added and coated to form a powder and, if necessary, granulate.

As the organic gelling agent used in the present invention, those generally used as gelling agents for liquid oils and fats can be used. Such organic gelling agents include, for example, alkali metal salts and polyvalent metal salts of mono- or di-long chain alkyl phosphates, preferably long-chain fatty acid alkali metal salts having an alkyl group of 8 to 22 carbon atoms, alkali Earth metal salt, dibenzylidene sorbitol, N-acylamino acid alkyl ester, N-acylamino acid alkyl amide,
Examples include N-oleylglycine-n-octylamide and N-lauroylglutamic acid dibutylamide. Alkali metal salts and polyvalent metal salts of mono- or di-long chain alkyl phosphates include mono- and dialkyl phosphates having an alkyl having 8 to 22 carbon atoms, preferably 14 to 22 carbon atoms, or a mixture thereof. Preference is given to salts, alkaline earth metal salts or aluminum salts.

Examples of the inert inorganic powder used in the present invention include sodium sulfate, which is commonly used as a builder, filler, or buffering agent in cleaning agents;
Sodium chloride, sodium bicarbonate, sodium carbonate,
Water-soluble neutral or alkaline inorganic salts such as sodium orthophosphate, sodium birophosphate, sodium tripolyphosphate, and sodium borate can be used.

Further, as the inert inorganic powder used in the present invention, water-insoluble inorganic compounds such as silica, crystalline or non-crystalline aluminum silicate, and calcium carbonate can also be used.

Examples of the inert organic powder include polyvinyl chloride, sodium citrate, and starch.

The particle size of the inert inorganic or organic powder used in the present invention is preferably one that allows 90% or more of the powder to pass through a 1000μ mesh sieve, and more preferably a particle size of 44μ or less.

As a method for gelling the liquid fragrance of the present invention using a gelling agent, a general method for gelling a liquid fat or oil can be used. The most commonly used method is to add organic gelling agent powder to a fragrance, stir, heat, dissolve, and cool to gel. A method such as stirring, mixing, and leaving the fragrance to stand may also be used.

When using the organic gelling agent dissolved in a solvent in advance, for example, lower alcohols such as methanol and ethanol, acetone, tetrahydrofurfural, terpene solvents,
Organic solvents such as paraffinic hydrocarbons, 3-methyl-3-methoxybutanol, and ethylene glycol 7-ethyl ether are used.

When melting by heating, the melting temperature is not particularly limited, but is generally 60 to 100°C, preferably 70 to 90°C.

The gelled fragrance is mixed and powdered in a stirrer while adding an inert inorganic or organic powder. Alternatively, the gel-like fragrance may be pulverized into fine particles under high shear and added to a fluidized bed in which an inert inorganic or organic powder is fluidized.

Alternatively, the solvent/fragrance gel solution can be directly sprayed into a fluidized bed containing flowing inert inorganic or organic powder to atomize it.
Powderization and solvent removal may be performed in one step.

The perfume powder thus obtained may be used as it is, or may be granulated with a binder if necessary.

The powdered fragrance obtained by the method of the present invention is particularly advantageously used in powdered detergents exhibiting alkalinity.

The cleaning composition of the present invention contains one type of cleaning active agent 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 to 60% by weight and 30 to 80% by weight of detergent builder in powder, granular or solid detergent compositions.
．． 1 to 5% by weight of the powdered fragrance obtained by the above method is blended.

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