Abstract

There is described a smokeless candle which contains insect or Chinese wax, in addition to paraffin wax, to prevent generation of soot, when the burning flame of the candle flares.

Description

Smoke-free candle

The present invention relates to a kind of candle, a kind of more specifically smoke-free candle, it does not produce in combustion processes or does not almost have cigarette, and it can contain spices, generation fragrance when burning.

So far, used beeswax and Japan wax, but still mainly used now petroleum wax in the paraffin and it and polyethylene wax or stearic mixture as the feedstock production illuminating bright candle.

In candle, comprise the candle that Japan produces, a kind of being called " smokelessly ",, the type of candle went on the market, it shows as perfect combustion and does not see the generation of cigarette in calm condition, but unavoidably there is cigarette to produce once in a while when under wind or analogue are arranged, making the combustion flame flicker, even very a spot of cigarette.

Alleged " scented candle " produces fragrance in combustion processes, a kind of candle is disclosed among the Japanese Patent 9-188893 (A), it is that fragrance precursor is added in the paraffin and polyethylene wax and the mixture of senior aliphatic carboxylic acid as supplementary component as main component, and the decomposition owing to fragrance precursor when burning of described candle produces fragrance.In recent years, the various candles that contain spices go on the market, and the fragrance therapy is an one purpose, because the light of candle or combustion flame have the effect of propitiator's spirit.

The candle of making by paraffin or with the candle of paraffin as main component, if surrounding environment keeps windless condition, its burning is bordering on perfect combustion and almost smokelessly produces only, but it has following shortcoming.

(1) when combustion flame because wind or other situation when flashing, have of short duration cigarette produces indoor environment is worsened,

(2) the combustion flame tip is long, and there is safety problem like this and shortened total combustion time,

(3) when the flame that puffs the candle out, can produce certain intensive distinctive smell (offensive odour), and

(4) when the quantity of selecting liquid perfume and putting into bigger the time, the hardness of candle diminishes, if use moulding method manufacturing like this, the shape of candle will be limited to bar-shaped.This means that could obtain shape in the container that wax should be poured into glass or other different shape is not bar-shaped candle, this kind candle must be with container to sell together.

Main purpose of the present invention for this reason provides a kind of smoke-free candle, and it contains paraffin as one of its wax component, but the generation of cigarette obviously is suppressed or does not produce cigarette.

Another object of the present invention provides a kind of smoke-free candle, and it is shorter than common candle that it shows as combustion flame, thereby makes total combustion time relative longer than common candle.

Another object of the present invention provides a kind of smoke-free candle, even the liquid perfume amount that adds in the wax component is more, it is the demoulding easily also, therefore can use known moulding method to manufacture the candle of different shape.

The present invention also has another purpose to be, a kind of smoke-free candle is provided, it has soft pastel shade and uniform hue, give transparent sensation, some commercially available scented candles have very shade, paraffin and various coloring material in general, particularly liquid color material avidity is lower, causes scented candle to use coloring material to avoid producing inhomogeneous tone in a large number.

According to the present invention, the main purpose that reach is to obtain smoke-free candle, and it comprises paraffin and insect wax or Chinese wax (Chinese wax) the wax component as it.

According to the present invention, in the wax component of smoke-free candle selected insect wax be by the second instar larvae excretory of wax insect and stick to Chinese ash and glossy privet trunk and branch on, purified this wax shows as the tone off-white and has high relatively fusing point 80-83 ℃.The contriver is surprised to find that the candle of making by adding insect wax in paraffin has following advantage, thereby has finished the present invention.

(a) generation of cigarette obviously is suppressed.

(b) short (the about 1cm of combustion flame, be the candle made by paraffin flame height half or shorter), make that so elongated (main purpose of the present invention did not also lie in illuminating bright candle was provided combustion time, but scented candle, therefore short combustion flame is not a shortcoming, is advantage on the contrary on angle safe in utilization).

(c) when puffing the candle out flame, do not produce the inherent offensive odour of the candle of doing as paraffin.

(d) even add the liquid perfume of about 10% weight in the wax component, the wax of fusing still can form the good candle of hardness by molding methods, and each candle can produce fragrance in various degree when burning thus.

(e) Rong Hua wax mixture and various liquid colourant show good affinity, and produced like this candle has soft photochromic accent and do not have uneven colour attaching area, gives the sensation of transparent color.

(f) because the air upflow of candle combustion, the end of the combustion flame of common candle is sharp-pointed and almost ceaselessly flashes, but the combustion flame of candle of the present invention its end circle and be stable is slightly as a whole given soft or quiet sensation.

In smoke-free candle of the present invention, preferred insect wax accounts for the 5-60% weight of wax component.This is that the generation frequency of cigarette can obviously reduce when combustion flame is forced to flash with hand when accounting for 5% weight owing to insect wax; Because flame height is shorter, about 1cm, even since flame flicking or wave may and of short duration generation cigarette, the amount of generation cigarette is also considerably less.In this respect, the flame height that please notes the scented candle of commodity selling is 2cm or higher.If forming, insect wax accounts for 60% weight or more for a long time, the curing of wax mixture then shows as too high hardness in mould, therefore, is when having the die forming of meticulous or complex structure when what adopt, may break or rupture when the candle demoulding, this is also inadvisable concerning production cost.

Although depend on the kind of spices,, if the excessive concentration of spices in the scented candle, its fragrance also may produce sensation beastly.The 0007th section record in aforesaid Japanese Patent 9-188893 (A) " amount of fragrance precursor in for candle; according to the kind of spices; with precursor form be controlled at 0.01-20% weight, more preferably 0.05-10% weight, and further preferred 0.1-5% weight ", that is to say and recommend to add low relatively precursor quantity, the preceding in an embodiment scale of construction only accounts for 1% weight of the wax component that is called " incendiary material ".Yet with regard to smoke-free candle of the present invention, because flame height is short, the release of fragrance has downtrod trend, therefore must set the amount of spices in higher slightly level.Made or contained paraffin does not contain insect wax as main wax composition common scented candle by paraffin, its hardness will reduce when containing a large amount of liquid perfume, bring problem to stripping operation.The manufacturing of candle of the present invention has relative higher melt 80-83 ℃ insect wax in contrast in the composition, therefore can not cause distortion in the smoke-free candle demoulding step.Smoke-free candle of the present invention, the wax amount when burning under the melt flow is very little, and therefore, the degree of delamination is quite low around the wax when candle combustion extinguishes fully naturally.That is to say, candle of the present invention, its housing parts keeps original shape substantially.Note that the scented candle of selling on the market of being made by paraffin, still unburned wax has lost original shape fully.

To further explain the present invention with test implementation example and preparation embodiment below.

It below is the raw material that in test implementation example and manufacturing embodiment, uses.

(1) wax

(a) paraffin:

Commercially available purified product, 135 of fusing points.

(b) insect wax:

Japan Kanagawa-ken, the purified product that Cera Rica Noda company limited produces.

(2) tinting material

(a) red colorant:

R-225 (working concentration: 0.3mg/ml).

(b) blue colorant:

B-403 (working concentration: 0.3mg/ml).

(c) green pigment:

G-202 (working concentration: 0.3mg/ml).

(d) yellow colorant:

Y-204 (working concentration: 0.1mg/ml).

Please note that " R-225 " etc. is the label of distinguishing colorant.

Test implementation example 1 (cigarette produces test)

The various candles that use the cylindrical die manufacturing to be made up of by different ratios paraffin and insect wax are so that candle is easy to the demoulding.Light each candle it is burnt under calm condition, near candle combustion flame, put a blank sheet of paper, agitate flame to make flame flicking with hand then, produce the frequency of cigarette by visual inspection.The results are shown in the following table 1.

Table 1

Raw material (% weight)		Produce the frequency of cigarette
			Paraffin	Insect wax
0 20 40 60 80 83 85 88 90 93 95 97 100	100 80 60 40 20 17 15 12 10 7 5 3 0				○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ × ×

In table 1,

00000: in 100 test of many times, do not observe the generation of cigarette,

0000: in 100 tests, have and observe the generation cigarette 1-2 time,

000: in 50 tests, have and observe the generation cigarette 1-2 time,

00: in 25 tests, have and observe the generation cigarette 1-2 time,

Zero: in 10 tests, have and observe the generation cigarette 1-2 time, and

*: at every turn or basically each test all can be observed the generation cigarette.

Analyze:

Can obviously find out from table 1 result, when making candle, in paraffin, add insect wax the generation number of times of cigarette significantly or is widely reduced.The result shows, other factors is taken into account, and the lower limit that adds insect wax is to be less than 5% weight, and seems that actual upper bound is about 60% weight.In addition, the also unexpected candle only made as the wax composition by paraffin found when flame blow-off, produces wax institute's inherent intensive and offensive odour, and by the candle that insect wax and paraffin are made, and does not produce or has only very faint this smell.

Test implementation example 2 (hardness of stripping feature and candle)

Listed paraffin ratio in the table 2 below adopting puts it into beaker and melts by heating in water bath.Simultaneously, pull it after the candle cotton core being immersed the paraffin of fusing, the wax composition solidifies, and prepares the cotton core that is soaked with wax and is connected with pedestal.This pedestal is the aluminium dish that has little central opening, and the cotton core that is soaked with wax passes its central opening and is attached on the pedestal.The cotton core that is soaked with wax that will have a pedestal be dome-type basically and have the mould of an aperture to be connected at its top.In this case, the cotton core that is soaked with wax is inserted in the hole of mould, so that the free end of cotton core stretches out some desire to make candle with formation the part of lighting slightly from the hole.Adhere to the contact part of the opening of the cotton core be soaked with wax and mould mesopore then with the beeswax of fusing, be fixed in the mould thereby beeswax solidifies the cotton core that is soaked with wax that will have pedestal.

Rose is added in the wax mixture of described fusing the back and stir the gained mixture, pour in the inverse mould with the mould reversing and with the wax of fusing.At this moment, adjust the amount of pouring into of fusing wax, so that the horizontal plane of fusing wax is a little more than the lower surface of pedestal.At this moment pour into the surface cure of wax of the fusing of mould, change mould over to refrigerator (temperature in the refrigerator :-5 ℃) cooling, and make the wax completely solidified in the mould.

Subsequently, from refrigerator, take out mould, with the prepared candle demoulding and estimate its demoulding ability, that is to say whether candle is easy to the demoulding.The results are shown in following table 2.

And the penetration degree of measuring prepared candle sample by the method for describing among the JIS K-2235 is to detect its hardness.The result also lists in the following table 2.

Table 2

Wax ﹠ spices (% weight)			Stripping feature	Penetration degree (25 ℃)
					Paraffin	Insect wax	Spices
40 40 40 100	60 60 60 0	0 6 10 0						○ ○ ○ △	8.8 11.6 12.8 12.1
			A commercially available prod, commercially available prod B			△ ×	18.8 31.0

In table 2,

Zero: be easy to the demoulding,

△: some difficulty of the demoulding, and

*: candle can not be pulled out from mould.

Analyze or assessment:

Even the liquid perfume that contains in the wax composition is under the situation of 10% weight, it is little and have enough hardness to make to be easy to carry out molded operation and tractive subsequently or to pull out operation to obtain required candle product to contain the wax mixture penetration degree of insect wax.The demoulding ability that contains the wax of insect wax is better than the Wax composition of paraffin and commercially available scented candle.

And, if affirmed that by other test scented candle only uses paraffin and liquid perfume, and make by molding methods, the liquid perfume amount that adds with respect to paraffin is limited to about 5-6% weight, otherwise the hardness of its wax can become too little so that cause that candle distortion or part wax adhere to the internal surface of mould and can not obtain ideal scented candle product certainly.This means that the paraffin that contains a large amount of liquid perfumes is not suitable for making scented candle by molding methods, sell in that this just requires it is poured into glass or earthenware porcelain receptacle or the bottle and with container.

Test implementation example 3 (continuous burning test)

Paraffin and insect wax with different proportionings are made various candles (weight of each candle sample: 20g, shape: semisphere).Light every candle and continuous burning,, observe the variation of candle shape and measure total continuous burning time (, rekindling immediately) if candle extinguishes naturally until cotton core extinguishes along with the disappearance of time.The proportion of composing of wax and accumulative total are listed in the following table 3 combustion time.

Table 3

Raw material (% weight)		Accumulate combustion time (branch)
			Paraffin	Insect wax
0 20 40 60 80 100	100 80 60 40 20 0				260 240 230 190 170 160

Analyze:

Accumulative total is elongated combustion time, particularly contains the candle of a large amount of insect waxes.When off-test, the candle sample that does not contain insect wax, exist and lose original shape fully with the state of residual a small amount of fusing wax, and contain the candle sample of insect wax, its housing parts is tending towards holding its shape and not fusing, more particularly, does not contain the candle sample of paraffin, housing parts holds its shape basically, promptly as the bowl shape.

Embodiment 1

Get paraffin (60g) and insect wax (40g), these waxes are put into beaker and used the water-bath heat fused.Simultaneously, the candle candle wick is immersed in the paraffin of fusing, make the candle wick that is soaked with wax as test implementation example 2 then.The candle wick that is soaked with wax is cut into several sections, and every section candle wick is attached to pedestal, and the candle wick bar that will have pedestal is fixed on the hemispheric stainless steel mould.

In the wax mixture of fusing, add rose (3 or 6g) and red colorant (3.2ml) or blue colorant (6.4ml) and stir, the gained mixture is poured in each mould.Mould is put into refrigerator, the wax completely solidified in the mould, the demoulding obtains the required semisphere candle that contains rose (every candle weight: 15g) then.

Every candle is soft light red or pale blue tone, does not have uneven tone zone, gives transparent sensation.
