Definitions

  • This invention relates generally to candles and more specifically to clear candles comprising a gel.
  • the clear candle body of this invention comprises a heterophase thermally reversible mineral oil gel formed by a system of physically crosslinked block copolymers.
  • the gel consistency may be controlled by varying the amount, ratio and types of certain copolymers, including diblock and triblock copolymers, so as to provide a gel which has desirable properties for a stable, safe, and attractive clear candle.
  • the heat of the candle's flame melts a small pool of the candle body material around the base of the exposed portion of the wick, and this molten material is then drawn up through and along the wick by capillary attraction, to fuel the flame.
  • a candle's melting point is critical, in that the candle material should liquefy at or below temperatures to which the candle's material can be raised by radiant heat from the candle flame. If the candle's melting temperature is too low, the candle will drip or, in an extreme case, the entire candle body will melt, dropping the wick into a pool of molten body material, with the potential that the surface of the pool could ignite.
  • the candle body material burn with a flame that is both luminous and smokeless, and the odors that are produced by its combustion should not be unpleasant or intrusive.
  • the candle body of this invention is made by the physical cross linking of co ⁇ polymers to form a gel which is heterophase
  • heterophase as used herein means a 2-phase system, which comprises an "oil” phase and a “block co-polymer” phase, the two phases being separate chemically and on a micro scale physically, but indistinct on a macro scale physically), and thermally reversible (i.e., when the gel is heated, the chemical composition of the gel remains the same, only physical properties of the gel - such as viscosity - change).
  • the clear candles disclosed in the prior art are typically manufactured with a thermoplastic polyamide resin which requires a chemical reaction to solidify the gel.
  • polyamide resin materials of these prior candles when heated, melt into and form chemical substances different from the original monomers or chemical constituents.
  • these polyamide resin based clear candles are not thermally reversible.
  • a characteristic polyamide resin based candle is disclosed in United States patent 3,819,342 ("the '342 patent"). This patent discloses a transparent candle composition comprising a thermal plastic polyamide resin and a flammable solvent described as being capable of solubilizing the resin at a temperature below about 212°F, and forming a transparent gel-type structure.
  • the solvent of the '342 patent is selected from the group consisting of unsaturated fatty acids, unsaturated fatty alcohols, saturated fatty alcohols, esters of fatty acids with polyhydric alcohols and glycerol, and mixtures thereof, and being present in amounts sufficient to gel the resin.
  • Additional materials used in this candle are coloring, anti-flaring compounds, perfumes, clarifying agents. Examples of different anti-flaring compounds are listed, however, the requirement of an anti-flaring compound points out a most serious problem with all polyamide resin based candles. Specifically, polyamide resins are known to separate into layers, and, after separation, the top of the candle is covered with an oil layer that flashes when lit.
  • the '289 patent discloses another clear candle that is chemically very similar to the devices of the '342 patent discussed above.
  • the '289 patent discloses a candle composition which may be transparent or pastel shaded and which is allegedly adapted to incorporate perfumes without flashing during burning.
  • the basic composition of the '289 patent comprises a thermoplastic polyamide resin formed from linoleic acid polymerized with polyamide compound; an alkolamide or alkanol; and a stearic acid compound.
  • the '289 patent further describes the use of polyamide resins to allegedly help eliminate "sweating" and to provide a smoother and glossier finish.
  • Sweating is the process whereby oils migrate out of the candle body to the surface, giving it a oily texture, and is most commonly caused by syneresis. Syneresis occurs when oil is physically squeezed out from the candle body because of excessive chemical crosslinking. Sweating is not only an aesthetic drawback, it can be a performance or safety problem as well. If a candle sweats, the oil on the surface is available to ignite, which can result in an uncontrolled or torch- like situation rather than a candle.
  • the gel based candle of the present invention does not sweat or separate, because syneresis can be easily controlled by adjusting the ratio of diblock to triblock polymers to insure that all of the oil is entrained within a system of physically crosslinked copolymers.
  • the '289 patent also discusses the optional addition of ionic surface agents to prevent "blooming" or fogging of the candle which would result in the loss of transparency. This is significant because another persistent complaint about commercially available polyamide resin based candles is that they are initially cloudy or they become cloudy over time. The addition of the ionic surface agents may help this problem in some cases, but it does not eliminate cloudiness in the polyamide resin based candles. In stark contrast, candle's made according to this invention start out clear, remain clear during burning, and do not "bloom” or fog over time.
  • United States patent 3,645,705 discloses a transparent candle body material formed by combining a straight chain aliphatic amide with white mineral oil and alcohol.
  • the '705 material is therefore, polyamide resin based, and is described as providing a molded, solid, and free standing product.
  • the resin is mixed with natural oils to cause it to gel.
  • This invention claims to be transparent as glass but slightly yellow due to the oil content. There is also a methyl ester added for hardness.
  • the lack of pigment and/or dye is referred to numerous times in the disclosure, but there is no disclosure that the wax used is any different than the opaque paraffin wax used in normal candle making.
  • the clear candle of the present invention is a true candle that burns and is consumed, and it is not a wax based candle but rather a gel based system of physically crosslinked copolymers.
  • the clear candle of this application addresses and overcomes the structural, aesthetic and functional problems of prior art candles by providing a gel body of the present invention is formed by physically crosslinked block copolymers in a heterophase thermally reversible mineral oil gel.
  • the paraffin wax or polyamide thermoplastic resin products known heretofore cannot provide a stable, clear candle having the structural and performance advantages as set forth herein.
  • block copolymers which can be advantageously used as one or more components in the present invention.
  • These block copolymers are described as gels or gelloid liquid extended polymer compositions which can comprise an intimate mixture of a block copolymer containing relatively hard blocks and relatively elastomeric blocks.
  • the additional polymer or copolymer material of this disclosure is to have at least partial compatibility with and a higher glass transition softening or melting temperature than the hard blocks of the block copolymer, and at least 500 parts by weight of extender liquid per 100 parts of the block copolymer, the liquid being present to extend and soften the elastomeric blocks of the block copolymer.
  • the extender liquid can be a hydrocarbon oil and/or a synthetic oil and the resulting gels or gelloid compositions are of the type which can be used in the clear candle of the present invention.
  • the '603 publication is hereby incorporated by reference herein.
  • gel material as described in United States patent 5,221,534 can also be utilized as the gel material for the body of the candle of the present invention.
  • the '534 patent describes a health and beauty aid gel composition comprised of one or more health and beauty aid components, a mineral oil, and a blend of at least two different polymer members.
  • the viscous, yet flowable material of the '534 patent was initially contemplated by the present applicant as a potential additive for standard wax based candles to enhance quality and to make them softer and less brittle, because the material of the '534 patent does not coke during burning. As a candle burns down into a container there may be insufficient oxygen at the bottom of the container to support complete combustion.
  • Particles of incomplete combustion can thereby form on the upper inside edge of the container; coking typically takes the form of a black smudge-like ring around the top of the container.
  • soot Particles of incomplete combustion
  • coking typically takes the form of a black smudge-like ring around the top of the container.
  • One object of the present invention is to form a non-coking candle which burns cleaner than both wax and polyamide resin based candles.
  • the gel candle of the present invention may be starved for oxygen, the gel candle burns slower than wax and the oxygen demands are less, thus the potential for coking is obviated.
  • Wax based and polyamide resin based candles burn more than 2 times faster than the gel material of this invention. In other words, the time to consume the entire clear gel candle takes more than twice as long as a standard paraffin wax, based on the same size and shape, candles.
  • Another object of the present invention is to mold a candle, which when colored, does not fade, is more stable and longer lasting than both wax and polyamide resin based candles.
  • Wax based and polyamide resin based candles are typically dyed with organic dyes which are sensitive to light. Pigments are not used in molded candles because they effect the burn of a wax based candle and they decrease the clarity of a polyamide resin based candle.
  • a colored wax based or polyamide based candle sits on a table, or in any form of light, it's color begins to fade over time.
  • the dye fades due to a chemical reaction of the organic dye with the organic candle body material in the presence of light and oxygen.
  • the gel material of this invention does not chemically react with dyes and therefore, the color fades significantly less over time.
  • a further object of the present invention is to form a candle which has a lower tendency to become brittle with age, as compared to wax based candles and polyamide resin based candles.
  • Polyamide resin based candles become brittle as the oil component separates, or "sweats" out of the candle body.
  • the gel candle body of this invention addresses this problem, as the gel is stable over time because the oil component is permanently entrained in the system of crosslinked copolymers. Furthermore, there are no chemical reactions occurring between components within the gel candle body so there is no gradual deterioration as is common with wax.
  • Yet another object of the present invention is to form a candle which is thermally reversible.
  • This thermal reversibility gives the clear candle of the instant invention significant process advantages over polyamide resin based candles.
  • the polyamide resin based candles are solidified via a chemical polymerization reaction. This reaction cannot be reversed and all mixing, pouring and molding must be done at one time. Any mistakes in the molding process and a polyamide candle is ruined.
  • the thermally reversibility of the clear candle of the present invention allows the easy mixing of color(s) and/or fragrance(s).
  • the clear candle of the present invention may be poured into containers in one step or a series of steps.
  • the manufacturer has great latitude in processing because after the gel is cooled it can be reheated to a fluid state, reworked, and recooled any number of times. Thermal reversibility allows the manufacturer to recycle material. For instance, if one candle container sells better than another, premade candles can be heated, removed from their old containers and poured into a more popular container. This recycling is not possible with a polyamide resin based candle. It is also an object of the present invention to form a candle which does not exhibit syneresis. Syneresis, the secretion of oil from a gel due to excessive crosslinking, is a serious problem with the polyamide resin based candles as discussed above.
  • the polyamide based candles are chemically crosslinked to such a great extent that oil is exuded therefrom and oil layers can form.
  • the presence of an oil layer on a candle is a serious safety concern.
  • the gel candle body of the present invention is not prone to syneresis. Because physical, as opposed to chemical, crosslinking is involved the ratio, amount, and type of copolymers can be controlled to eliminate syneresis.
  • the copolymers form three-dimensional networks or gels through physical crosslinks. Crosslinking in these block copolymers occurs due to the formation of submicroscopic particles of a particular block, referred to as domains.
  • Crosslinking of the insoluble domains can be obtained by factors affecting the crosslink density of the networks including length of insoluble block domains, length of soluble block domains, and the number of crosslinkable sites.
  • branched or star polymers will have more crosslinks than triblock or diblock polymers.
  • the type of solvent or plasticizer to which the blocks are subjected will also affect these characteristics.
