Abstract
A gel type fragrant composition for use as an air freshener may be provided as a block in a polystyrene tray which is suitable for placing in a fragrance dispenser. The fragrant composition comprises an oil based synthetic fragrant compound, a binding agent such as sodium stearate, a solubilising agent such as hydrogenated castor oil and a volatiles release controlling agent such as isopropyl myristate. The fragrant composition, when provided in blocks of 4 grammes, has an effective life of at least 35 days.
Description
The present invention relates to a gel type fragrant composition, and to a method for preparing the gel type fragrant composition.
Fragrant compositions are commonly used as air fresheners, and typically are provided in solid block or gel form. Such compositions include a volatile fragrant compound which releases volatiles which give the fragrance. Where provided in a gel form, the gel is normally supplied in a covered tray, the cover of which is removed to permit release of the volatiles.
The block of fragrant composition or tray of fragrant gel composition may be left in a room where the volatiles are released into the room, thereby providing a pleasant fragrance in the room.
Alternatively, the block or tray of gel may be placed in an air stream whereby air is continuously or intermittently passed over a surface or surfaces of the block or gel to rapidly diffuse the volatiles and in turn the fragrance throughout the room. Typically a block or tray of gel may be placed in a fragrance dispenser, which would normally comprise a housing. A fan mounted in the housing passes an air stream across a surface or surfaces of the block or gel which entrains the volatiles and in turn diffuses the volatiles through an outlet in the housing into the room or the like, typically, a bathroom or toilet.
In general, as well as the volatile fragrant compound, fragrant compositions comprise a fragrant solubilising agent and a binding agent.
A major problem of most known fragrant compositions is that the volatiles of the fragrant compound are released at a non-uniform rate. In general, the volatiles are rapidly released in the initial stages of exposure of the composition, while in due course the rate of release of the volatiles drops rapidly, and after a relatively short period of time the rate of release of volatiles from known compositions is, in general, insufficient to be effective. In general, known fragrant compositions seldom have an effective life of more than five days after initial exposure.
This causes considerable problems, in that, where fragrant compositions are used in institutions, such as, for example, toilets of hotels, bars, offices and the like, the fragrant composition must be replaced on a relatively regular basis. In cases where the fragrant composition is placed in a dispenser, the cost of servicing such dispensers every five days or less to replace the fragrant composition is relatively time consuming, and in turn costly. In many cases, a service person may have to travel considerable distances from location to location where the fragrance dispensers are provided.
There is therefore a need for a fragrant composition which overcomes these problems. There is also a need for a method for preparing such a fragrant composition.
The present invention is directed towards providing a gel type fragrant composition and a method for preparing the gel type fragrant composition.
According to the invention there is a provided a gel type fragrant composition comprising an oil based fragrant compound, a binding agent, a solubilising agent, and a volatiles release controlling agent for controlling the rate of release of the volatiles of the fragrant compound from the composition.
Preferably, the volatiles release controlling agent is isopropyl myristate. Advantageously, the volatiles release controlling agent constitutes in the range of 25% to 50% by weight of the composition, and preferably, the volatiles release controlling agent constitutes in the range of 35% to 45% by weight of the composition. In a preferred embodiment of the invention, the volatiles release controlling agent constitutes approximately 40% by weight of the composition.
In another embodiment of the invention, the oil based fragrant compound constitutes in the range of 30% to 50% by weight of the composition, advantageously, the oil based fragrant compound constitutes in the range of 30% to 40% by weight of the composition, and preferably, the oil based fragrant compound constitutes approximately 35% by weight of the composition. Preferably, the oil based fragrant compound is an oil based synthetic fragrant compound.
In another embodiment of the invention, the binding agent is sodium stearate, advantageously, the binding agent constitutes in the range of 6% to 10% by weight of the composition, and preferably, the binding agent constitutes approximately 8% by weight of the composition.
In another embodiment of the invention, the solubilising agent is hydrogenated castor oil, and advantageously, the solubilising agent is PG-40 hydrogenated castor oil, and preferably, the solubilising agent constitutes in the range of 5% to 15% by weight of the composition, and in a preferred embodiment of the invention, the solubilising agent constitutes approximately 10% by weight of the composition.
In a further embodiment of the invention, the fragrant composition is provided in a tray, the tray containing in the range of 2 grammes to 10 grammes of the fragrant composition, preferably, the tray contains in the range of 2 grammes to 6 grammes of the fragrant composition, and advantageously, the tray contains 6 grammes approximately of the fragrant composition.
Preferably, the tray is of polystyrene material, and is preferably provided with a releasable cover.
Advantageously, the tray is of shape and dimensions to provide an exposed surface of the fragrant composition of area in the range of 3,000 sq mm to 9,000 sq mm, and preferably, the tray is of shape and dimensions to provide an exposed surface of the fragrant composition of area in the range of 4,000 sq mm to 7,000 sq mm.
Advantageously, each tray is of shape and dimensions to provide an exposed surface of the fragrant composition of area of approximately 4,875 sq mm.

Further, the invention provides a method for preparing the fragrant composition according to the invention, the method comprising the steps of mixing the solubilising agent, the binding agent, and the volatiles release controlling agent together and raising the temperature of the mixture to a temperature in the range of 650C to 850C, adding a first portion of the oil based fragrant compound to the mixture at the raised temperature, allowing the mixture to commence to cool, adding a second portion of the oil based fragrant compound to the mixture as the mixture is commencing to cool, and agitating the mixture while the second portion of the fragrant compound is being added.
Advantageously, the mixture is continuously agitated for a further period of at least thirty seconds after the second portion of the fragrant compound has been added, preferably, the period during which the mixture is agitated after the second portion of the fragrant compound is added is approximately sixty to ninety seconds.
In one embodiment of the invention, the first portion of the oil based fragrant compound added to the mixture constitutes in the range of 25% to 75% by weight of the fragrant compound, and preferably, the first portion of the oil based fragrant compound added to the mixture constitutes in the range of 40% to 60% by weight of the fragrant compound, advantageously, the first portion of the fragrant compound added to the mixture constitutes approximately 50% by weight of the fragrant compound.
In another embodiment of the invention, the temperature of the mixture of solubilising agent, binding agent and volatiles release controlling agent is heated to a temperature in the range of 700C to 800C, advantageously, the temperature of the mixture of solubilising agent, binding agent and volatiles release controlling agent is heated to a temperature of approximately 750C.
In a further embodiment of the invention, water is added to the mixture prior to the temperature of the mixture being raised, the water constituting in the range of 5% to 10% by weight of the fragrant composition.
Preferably, the oil based fragrant compound is at room temperature prior to being added to the mixture.
Advantageously, the fragrant composition is poured into a plurality of trays and allowed to cool in the trays, and preferably, the fragrant composition is poured into the trays immediately after agitation of the mixture has ceased.
The invention will be more fully understood from the following description of some non-limiting examples.
Example 1
A gel type fragrant composition, which in this case is provided as a solid gel in trays is prepared from the following ingredients in the percentages by weight of the fragrant composition set out below:
water 7%
sodium stearate 8%
PEG-40 hydrogenated castor oil 10%
isopropyl myrestate 40%
oil based synthetic fragrant compound 35%
In this example, the oil based synthetic fragrant compound is a fragrant compound type A 136468 supplied in liquid form by Ungerer Limited of Great Britain.
The fragrant composition is suitable for use as an air freshener and releases a flat pine type fragrance.
The PEG-40 hydrogenated castor oil is in paste form and acts as a solubilising agent. In this embodiment of the invention the PEG-40 hydrogenated castor oil is sold by BASF Chemicals Limited of Great Britain under the trade name Cremophor RH40. The sodium stearate acts as a binding agent and in this embodiment of the invention is supplied in powder form by Durham Limited of Great Britain. The isopropyl myristate acts as a volatiles release controlling agent and in this embodiment of the invention is supplied in liquid form by Fina Chemicals Limited of Belgium.
Eight kilos of the fragrant composition is prepared.
The method for preparing the fragrant composition is as follows. The water, sodium stearate, PEG-40 hydrogenated castor oil and isopropyl myristate are mixed together in a suitable container, such as, for example, a stainless steel vat. The mixture is heated over a suitable heat source to a temperature of approximately 700C and is agitated by continuous brisk stirring during heating. On the temperature of the mixture reaching approximately 700C, a first portion, in this case 50% by weight of the oil based fragrant compound at room temperature is stirred into the heated mixture. The heat source is then removed from the container or vice versa, and cooling of the mixture commences. On removal of the heat source and just as the mixture commences to cool, a second portion, namely, the remaining 50% by weight of the oil based fragrant compound is stirred into the mixture.The entire mixture is continuously stirred for a period of approximately 60 seconds after all the fragrant compound has been stirred into the mixture.
The mixture is then poured into suitable trays and allowed to cool in the trays to form a gel block. In this example, 4 grammes of the fragrant composition are poured into each tray. On the fragrant composition cooling in the trays, the trays are then covered by a releasable cover to retain the volatiles within the gel. The trays containing the fragrant gel are now ready for use, and on removal of the cover emit the volatiles of the fragrant compound. The trays may be placed in a room or in a suitable fragrance dispenser.
In this example, the trays are of polystyrene material which is impermeable to the volatiles of the fragrant composition, and the releasable cover is also of polystyrene. The trays are of size 75 mm by 65 mm by 15 mm deep. The area of the exposed surface of the fragrant gel block from which volatiles are released is 4,875 sq mm.
Example 2
In this example, a batch of eight kilos of a gel type fragrant composition is prepared. The ingredients and their proportions are identical to those of Example 1 with the exception that the oil based fragrant compound is a fragrant compound type 136465 supplied in liquid form by Ungerer Limited. The fragrant composition releases a herbal type fragrance.
The method for preparing the fragrant composition is identical to that of Example 1 and the mixture is poured into trays similar to those described in
Example 1 and allowed to cool to form the gel type fragrant composition.
Example 3
In this example, a batch of eight kilos of a gel type fragrant composition is prepared. The ingredients and their proportions are identical to those of Example 1 with the exception that the oil based fragrant compound is a fragrant compound type 62138 supplied in liquid form by Fragrance Oils (International) Limited of Great Britain. The fragrant composition releases a floral type fragrance.
The method for preparing the fragrant composition is identical to that of Example 1 and the mixture is poured into trays similar to those described in
Example 1 and allowed to cool to form the fragrant composition.
Example 4
In this example, a batch of eight kilos of a gel type fragrant composition is prepared. The ingredients and their proportions are identical to those of Example 1 with the exception that the fragrant compound is a fragrant compound type 24595 supplied in liquid form by Fragrance Oils (International) Limited of Great
Britain. The fragrant composition releases a citrus type fragrance.
The method for preparing the fragrant composition is identical to that of Example 1 and the mixture is poured into trays similar to those described in
Example 1 and allowed to cool to form the fragrant composition.
Example 5
In this example, a batch of eight kilos of a gel type fragrant composition is prepared. The ingredients and their proportions are identical to those of Example 1 with the exception that the fragrant compound is a fragrant compound type 54548 supplied by Fragrance
Oils (International) Limited of Great Britain. The fragrant composition releases a herbal type fragrance.
The method for preparing the fragrant composition is identical to that of Example 1 and the mixture is poured into trays similar to those described in
Example 1 and allowed to cool to form the fragrant composition.
In tests, it has been surprisingly found that the effective life of the gel type fragrant composition of the examples is in all cases greater than 35 days. In the case of the fragrant composition of Example 1, the life of the fragrant composition is 39 days. Each test was carried out in a room of dimensions 12 metres length by 10 metres width by 8 metres height. The number of air changes in the room throughout the test was approximately 6 per hour. A tray containing 4 grammes of the fragrant gel with an exposed surface area of 4,875 sq mm was placed in a fragrance dispenser mounted on a wall of the room. The fragrance dispenser was of the type comprising a housing having a fan mounted therein which passed an air stream over the surface of the fragrant composition and subsequently diffused the air with the volatiles of the fragrant compound entrained therein into the room.The fan continuously delivered an air stream which was incident on the surface of the gel at an angle of approximately 900 at a flow rate of thirty cubic metres of air per hour.
During the entire 39 day life of the fragrant composition of Example 1, the rate of diffusion of the volatiles into the room was adequate to give a pleasant fragrance of a desirable level throughout the room.
The level of fragrance in the room was found to be substantially constant during the 39 day life of the fragrant composition. For the first 3 days of the test it was found that a relatively strong fragrance was provided in the room. However, while the fragrance was relatively strong, it was not objectionable. After the first 3 days of the test the level of fragrance in the room was substantially constant for the next 36 days, and was found to be at an acceptable level. After the 39th day of the test, the level of fragrance was found to have dropped below an acceptable level.
Why these new and surprising results have been achieved is not fully understood. However, it is believed that by providing a volatiles release controlling agent, the rate of release of volatile from the fragrant composition is regulated to be substantially constant over most of the effective life of the fragrant composition. In other words, the volatiles release controlling agent suppresses the rate of release of volatiles during the initial few days, and maintains the rate of release substantially constant over the effective life of the fragrant composition.
While in all the examples of the invention, the volatiles release controlling agent has been described as being isopropyl myristate, it is believed that reasonable results would be achieved with other constituents which possessed the property of acting as a volatile release controlling agent. It is believed that the following constituents would be suitable as volatiles release controlling agents:
iso propyl palmitate,
di propylene glycol,
di methyl phthalate,
di ethyl phthalate.
While this list is given as suggested constituents which would have properties suitable for acting as volatiles release controlling agents, it is not intended to be an exhaustive list.
While a specific compound has been described for use as a binding agent, other suitable binding agents could be used. Similarly, other suitable solubilising agents may be used. Needless to say, other oil based fragrant compounds could be used. Where other oil based fragrant compounds and/or other volatile release controlling agents are used, the proportions by weight of the volatile release controlling agent and the fragrant compound in the gel type fragrant composition may be varied.
Needless to say, the proportions of the other constituents of the gel type fragrant composition may also be varied.
While in the examples, the fragrant composition has been described as being provided in trays, it is envisaged in many cases that the fragrant composition would be provided in solid blocks without a tray. For example, in such cases, it is envisaged that the fragrant composition, after being mixed as described in the examples, would be poured into a mould to form solid gel blocks. On setting, the gel blocks would then be removed from the mould and packaged. The blocks may be packaged in any suitable packaging material, such as, for example, wrapping, boxes or the like. However, it is recommended that the packaging material used should be impermeable to the volatiles of the fragrant composition. The gel block packaged in this way would then be partly or fully removed from the packaging for subsequent use.
