Den foreliggende opfindelse angår en to-delt pakning med indhold til afgivelse af et selvopvarmende depilatorisk præparat-The present invention relates to a two-part package containing contents for dispensing a self-heating depilatory preparation.
Mange depilatoriske præparater har været foreslået i litteraturen, og flere er kommercielt tilgængelige. En ulempe ved den overvejende del af de tidligere foreslåede præparater er, at de er relativt langsomt virkende. Det er normalt nødvendigt at lade præparatet Q være i kontakt med huden i mange minutter, sædvanligvis ca. 10 mi- nutter, for at opnå gode resultater.Many depilatory preparations have been proposed in the literature and several are commercially available. A disadvantage of the majority of the compositions previously proposed is that they are relatively slow acting. It is usually necessary to leave the preparation Q in contact with the skin for many minutes, usually approx. 10 minutes to achieve good results.
2 f Virkningen af sædvanlige depilatoriske præparater er baseret på anvendelsen af metalsalte af thioforbindelser såsom thioglycolsyre ^ og thioglycerol. Virkningshastigheden for sådanne præparater afhæn- 2 147139 ger af a) pH-værdien i præparatet (sædvanligvis ca. 12), b) koncentrationen og arten af thioforbindelsen (sædvanligvis ca. 3 - 6%) og c) arten af metalionen (normalt natrium, kalium, lithium, calcium, barium eller strontium). Depilationshastigheden kan forøges ved at a) forøge pH-værdien, b) forøge koncentrationen af thioforbindelsen eller c) anvende et natrium-, kalium- eller lithiumsalt i stedet for et calcium-, barium- eller strontiumsalt. Uheldigvis er det ikke muligt at gå meget videre i nogen af disse retninger uden at støde på alvorlige hudirritationsproblemer.2 The effect of conventional depilatory preparations is based on the use of metal salts of thio compounds such as thioglycolic acid and thioglycerol. The rate of action of such compositions depends on a) the pH of the composition (usually about 12), b) the concentration and nature of the thio compound (usually about 3 to 6%), and c) the nature of the metal ion (usually sodium, potassium, lithium, calcium, barium or strontium). The rate of depilation can be increased by a) increasing the pH, b) increasing the concentration of the thio compound or c) using a sodium, potassium or lithium salt instead of a calcium, barium or strontium salt. Unfortunately, it is not possible to go much further in any of these directions without encountering serious skin irritation problems.
Som det kunne ventes, forøges depilationshastigheden for en thio-forbindelse med stigende temperatur. Dette faktum udnyttes f.eks. i de præparater, der er beskrevet i britisk patentskrift nr.As might be expected, the rate of depilation for a thio compound increases with increasing temperature. This fact is exploited e.g. in the compositions described in British Pat.
1.329.029, hvor der er beskrevet et selvopvarmende depilatorisk præparat, hvis virkning afhænger af den in situ forekommende dannelse af en aktiv depilatorisk forbindelse ved en exotermisk reaktion mellem to komponenter, der normalt holdes adskilt, men som blandes før eller under påføring på huden. Det er anført, at den exotermiske reaktion forhøjer temperaturen i præparatet og således forøger depilationshastigheden. Sådanne præparater er imidlertid ikke helt tilfredsstillende, idet det udvalg af forbindelser, som reagerer til dannelse af dermatologisk acceptable depilatoriske forbindelser under udvikling af tilstrækkelig varme til signifikant at forhøje temperaturen i hele præparatet, er yderst begrænset.No. 1,329,029, which discloses a self-heating depilatory composition, the effect of which depends on the in situ formation of an active depilatory compound by an exothermic reaction between two components which are normally kept separate but which are mixed before or during application to the skin. It is stated that the exothermic reaction raises the temperature of the composition and thus increases the rate of depilation. However, such preparations are not entirely satisfactory, as the range of compounds that react to form dermatologically acceptable depilatory compounds during the development of sufficient heat to significantly raise the temperature throughout the preparation is extremely limited.
Desuden er det meget afgørende, at de to adskilte komponenter i præparatet afgives nøjagtig samtidig, hvilket er nødvendigt for at opnå de bedste resultater. F.eks. fører et overskud af fri thio-syre til utilstrækkelig hårfjerning, og et overskud af base medfører irritationsproblemer.In addition, it is essential that the two separate components of the composition be delivered exactly at the same time, which is necessary to obtain the best results. Eg. an excess of free thio acid leads to insufficient hair removal and an excess of base causes irritation problems.
Principielt ville det være meget mere tilfredsstillende, hvis det tilsigtede selvopvarmende depilatoriske præparat fra starten kunne indeholde et aktivt hårfjerningsmiddel, samt yderligere bestanddele, som reagerer exotermisk, når de blandes. På denne måde kunne de mest egnede depilatoriske midler og de mest egnede varmeproducerende reagenser udvælges, uden at det var nødvendigt at gå på kompromis med egenskaberne for hvert af disse. Desuden ville problemet med nøjagtig samtidig afgivelse være meget mindre afgørende.In principle, it would be much more satisfactory if the intended self-heating depilatory composition could initially contain an active hair removal agent, as well as additional ingredients that react exothermically when mixed. In this way, the most suitable depilatory agents and the most suitable heat-producing reagents could be selected without compromising the properties of each. In addition, the problem of accurate simultaneous delivery would be much less crucial.

Uheldigvis er de eneste varmeproducerende systemer, som hidtil har været foreslået til anvendelse i topiske præparater, oxidations--reduktionssysterner og syre-base-neutralisationssysterner. Det første af disse er ikke anvendeligt til depilatoriske præparater, da de de-pilatoriske thioforbindelser selv er reduktionsmidler og forbruges af det komplementære oxidationsmiddel. Syre-baseneutralisation er også en utilfredsstillende måde at fremkalde varme i et depilato-risk system på, da de temperaturer, der opnås med dermatologisk acceptable syrer og baser sædvanligvis ikke er høje nok til at forøge depilationshastigheden.Unfortunately, the only heat generating systems that have so far been proposed for use in topical preparations, oxidation-reduction systems and acid-base neutralization systems. The first of these is not applicable to depilatory preparations, since the depilatory thio compounds themselves are reducing agents and are consumed by the complementary oxidizing agent. Acid-base neutralization is also an unsatisfactory way of inducing heat in a depilatory system, since the temperatures obtained with dermatologically acceptable acids and bases are usually not high enough to increase the rate of depilation.
Den foreliggende opfindelse bygger på anvendelsen i et depilatorisk præparat af en varmeproducerende reaktion, som ikke tidligere har været foreslået til anvendelse i topiske toiletartikler og kosmetiske præparater, nemlig reaktionen mellem calciumoxid og vand til fremstilling af calciumhydroxid, som er en dermatologisk acceptabel forbindelse, der allerede forekommer i de fleste depilatoriske præparater som hjælpebase til regulering af pH-værdien. Det har vist sig, at dette system kan give en meget god temperaturstigning i løbet af 1 minut eller 2 og signifikant reducerer depilations-tiden, under forudsætning af, at der iagttages forholdsregler til at sikre adækvat blanding af calciumoxidet og vandet.The present invention is based on the use in a depilatory composition of a heat producing reaction which has not previously been proposed for use in topical toiletries and cosmetic preparations, namely the reaction between calcium oxide and water to produce calcium hydroxide, which is a dermatologically acceptable compound which occurs in most depilatory preparations as an auxiliary base for regulating the pH. It has been found that this system can give a very good temperature rise over 1 minute or 2 and significantly reduces the depilation time, provided that precautions are taken to ensure adequate mixing of the calcium oxide and water.
Til forskel fra oxidations/reduktionssysternet og syre/base-neutra-lisationssystemet er nøjagtig samtidig afgivelse af de to komponenter ikke så kritisk, da depilationstiden under ingen omstændigheder vil blive langsommere end for de eksisterende depilatoriske komponenter.Unlike the oxidation / reduction system and the acid / base neutralization system, accurate simultaneous delivery of the two components is not as critical as the depilation time will under no circumstances be slower than for the existing depilatory components.
Den foreliggende opfindelse bygger på denne erkendelse og angår en to-delt pakning med indhold til afgivelse af et selvopvarmende depilatorisk præparat, hvilken pakning med indhold er ejendommelig ved, at den har en del, der indeholder et viskost, flydbart, vandigt præparat, og en anden del, der er adskilt fra den første, og som indeholder et viskost, flydbart, ikke-vandigt præparat, i hvilket der er dispergeret findelt calciumoxid, hvorhos det ene præparat eller både det vandige og det ikke-vandige præparat indeholder et aktivt 4 147139 depilatorisk middel, eller både det vandige og det ikke-vandige præparat indeholder reagenser, som, når de bringes i kontakt, reagerer til dannelse af et aktivt depilatorisk middel, hvorhos det vandige og det ikke-vandige præparat er i det væsentlige blandbare, hvorved der dannes et dermatologisk acceptabelt depilatorisk præparat. Pakningen skal have anordninger til afgivelse og blanding af det vandige og det ikke-vandige præparat eller til at bringe det vandige og det ikke-vandige præparat fra den ene og den anden del i kontakt med hinanden.The present invention is based on this disclosure and relates to a two-part package of contents for dispensing a self-heating depilatory composition, the package of contents being characterized in that it has a portion containing a viscous, flowable, aqueous composition, and a a second portion separate from the first containing a viscous, flowable, non-aqueous composition in which is dispersed comminuted calcium oxide, wherein one or both aqueous and non-aqueous compositions contain an active agent; depilatory agent, or both the aqueous and non-aqueous composition, contain reagents which, when contacted, react to form an active depilatory agent, wherein the aqueous and non-aqueous compositions are substantially miscible, whereby a dermatologically acceptable depilatory preparation is formed. The package must have means for dispensing and mixing the aqueous and non-aqueous compositions or to contact the aqueous and non-aqueous compositions of one and the other part.
Pakningen består i sin simpleste form af' to adskilte beholdere, f.eks. s ammentrykkelige tuber, hvorhos den ene indeholder den vandige væske, og den anden indeholder den ikke-vandige væske. I dette tilfælde er "anordninger til afgivelse og til at bringe i kontakt” simpelthen mundingerne i de to beholdere. Forbrugeren vil simpelthen trykke en del af hvert præparat ud af hver beholder og blande dem enten in situ på anvendelsesområdet eller på et blandested før påføring på anvendelsesområdet.The packing consists in its simplest form of two separate containers, e.g. s amenable tubes, one containing the aqueous liquid and the other containing the non-aqueous liquid. In this case, "dispensing and contacting devices" are simply the mouths of the two containers. The consumer will simply squeeze a portion of each preparation out of each container and mix them either in situ at the application site or at a mixing site prior to application to the container. scope.
En foretrukken pakningsform ifølge opfindelsen er en "tube-inden-i-tube". Denne indretning består af to sammentrykkelige tuber, den ene inden i den anden, med en fælles afgivelsesmunding, der er delt således, at den ene halvdel af den fælles afgivelsesmunding kun står i forbindelse med det indre af den yderste sammentrykkelige tube, og den anden halvdel kun står i forbindelse med det indre af den inderste sammentrykkelige tube. Når begge tuber er fyldt, den ene med det vandige præparat, den anden med det ikke-vandige præparat, vil et tryk på den yderste tube blive videreført til den inderste tube, hvorved der sker samtidig udtrykning af begge præparater gennem den fælles munding. I dette tilfælde er det klart, at "anordninger til afgivelse og blanding eller til at bringe i kontakt" er den fælles afgivelsesmunding. Forbrugeren vil blive tilskyndet til at blande det vandige og det ikke-vandige præparat in situ på huden ved let gnidning med fingeren ved den normale påføring.A preferred packaging form of the invention is a "tube-in-tube". This device consists of two compressible tubes, one within the other, with a common delivery mouth divided so that one half of the common delivery mouth communicates only with the interior of the outer compressible tube and the other half. only communicates with the interior of the innermost compressible tube. When both tubes are filled, one with the aqueous composition, the other with the non-aqueous composition, a pressure on the outer tube will be carried to the inner tube, thereby simultaneously expressing both compositions through the common mouth. In this case, it is clear that "dispensing and mixing or contacting devices" are the common dispensing mouth. The consumer will be encouraged to mix the aqueous and non-aqueous composition in situ on the skin by light rubbing with the finger during normal application.
Det vandige og det ikke-vandige præparat må være i det væsentlige blandbare. Dette er afgørende for at opnå intim kontakt mellem cal-ciumoxidet, som er suspenderet i det ikke-vandige præparat, 5 147139 og vandet, som forekommer i det vandige præparat, således at den nødvendige opvarmningsgrad opnås. Den opnåede opvarmningsgrad vil naturligvis afhænge af adskillige faktorer, især af koncentrationen af calciumoxid og varmefylden i disse samlede præparater. Det har vist sig, at de selvopvarmende egenskaber i de blandede præparater varierer inden for vide grænser, alt afhængig af den flydende basis for det ikke-vandige præparat. Det er naturligvis en rutinesag at afprøve forskellige organiske væsker, indtil der er fundet en væske, som har de nødvendige egenskaber.The aqueous and non-aqueous composition must be substantially miscible. This is essential to achieve intimate contact between the calcium oxide suspended in the non-aqueous composition and the water present in the aqueous composition to obtain the required degree of heating. The degree of heating obtained will, of course, depend on several factors, notably the concentration of calcium oxide and the density of these combined compositions. It has been found that the self-heating properties of the mixed compositions vary widely, depending on the liquid basis of the non-aqueous composition. Of course, it is a routine matter to test different organic liquids until a liquid has been found which has the necessary properties.
Det har vist sig, at mineralolie er en god basis for det ikke-vandige præparat, men i dette tilfælde er det nødvendigt at inkorporere en emulgator i olie/calciumoxidpræparatet for at forbedre blandbarheden med det vandige præparat.It has been found that mineral oil is a good basis for the non-aqueous composition, but in this case it is necessary to incorporate an emulsifier into the oil / calcium oxide composition to improve miscibility with the aqueous composition.
Det vandige og det ikke-vandige præparat skal være viskose, men flydbare. Dette krav skyldes, at det er nødvendigt at sikre, at calciumoxidet forbliver i suspension (hertil kræves en viskos væske, fortrinsvis en til gel omdannet væske), men også at præparaterne let afgives. Hvis det ikke-vandige præparat skal være en viskos væske, må det vandige præparat have omtrent samme viskositets egenskaber for at sikre jævn blanding og afgivelse. Hvis den flydende basis, som er valgt til det ikke-vandige præparat, ikke er tilstrækkelig viskos til at sikre en stabil dispergering af calciumoxidet, kan det være nødvendigt at tilsætte et fortykkelsesmiddel såsom findelt siliciumdioxid, og det kan være nødvendigt .at regulere det vandige præparats viskositet, så at den passer til viskositeten i det fortykkede ikke-vandige præparat.The aqueous and non-aqueous preparations must be viscous but flowable. This requirement is due to the need to ensure that the calcium oxide remains in suspension (for this a viscous liquid, preferably a gel converted liquid is required), but also that the preparations are readily dispensed. If the non-aqueous composition is to be a viscous liquid, the aqueous composition must have approximately the same viscosity properties to ensure smooth mixing and dispensing. If the liquid base selected for the non-aqueous composition is not sufficiently viscous to ensure a stable dispersion of the calcium oxide, it may be necessary to add a thickener such as finely divided silica and it may be necessary to regulate the aqueous. viscosity of the composition to match the viscosity of the thickened non-aqueous composition.
Et aktivt depilatorisk middel kan forekomme i det ene præparat eller i både det vandige og det ikke-vandige præparat. Alternativt kan det vandige og det ikke-vandige præparat hver indeholde reagenser, som, når de blandes, udgør et aktivt depilatorisk middel. Aktive depilatoriske midler er sulfider såsom strontriumsulfid, substituerede mercaptaner, især metalsaltene af thioglycolsyre, der er nævnt ovenfor, og keratinaseenzym. Eksempler på to reagenser, som reagerer til dannelse af en aktiv depilatorisk forbindelse, er natriumhydroxid og thioglycolsyre. Når der som det aktive depilatoriske middel vælges et metalsalt af thioglycolsyre, er det naturligvis 6 147139 kendt, at pH-værdien i hele det resulterende depilatorlske præparat må ligge i området mellem 10,0 og 12,5, da metalthioglycolat ikke er mærkbart aktivt uden for dette område. Da slutproduktet af reaktionen mellem vand og calciumoxid er calciumhydroxid - en mild base -må mængden af yderligere base såsom natriumhydroxid, som er nødvendig for at opnå det ønskede pH-område, indstilles i overensstemmelse dermed.An active depilatory agent may be present in either composition or in both aqueous and non-aqueous compositions. Alternatively, the aqueous and non-aqueous compositions may each contain reagents which, when mixed, constitute an active depilatory agent. Active depilatory agents are sulfides such as strontium sulfide, substituted mercaptans, especially the metal salts of thioglycolic acid mentioned above, and keratinase enzyme. Examples of two reagents that react to form an active depilatory compound are sodium hydroxide and thioglycolic acid. Of course, when a metal salt of thioglycolic acid is selected as the active depilatory agent, it is known that the pH of the entire resulting depilatory preparation must be in the range of 10.0 to 12.5, since metal thioglycolate is not appreciably active without for this area. Since the final product of the reaction between water and calcium oxide is calcium hydroxide - a mild base - the amount of additional base such as sodium hydroxide needed to achieve the desired pH range must be adjusted accordingly.
Det vandige og det ikke-vandige præparat må være blandbare, således at der dannes et dermatologisk acceptabelt depilatorisk præparat. Således må komponenterne i det vandige og det ikke-vandige præparat foruden de allerede nævnte (calciumoxid, ikke-vandigt viskost bærestof, aktivt depilatorisk middel og, om nødvendigt, hjælpebase) vælges sådan, at de er ikke-irriterende og sikre under de gængse omstændigheder, og emulgatorer, fugtighedsbevarende midler, parfumer og andre sædvanlige depilatoriske additiver, som forekommer enten i det vandige eller i det ikke-vandige præparat, må således naturligvis være kompatible.The aqueous and non-aqueous compositions must be miscible to form a dermatologically acceptable depilatory preparation. Thus, in addition to those already mentioned (calcium oxide, non-aqueous viscous carrier, active depilatory agent, and, if necessary, auxiliary base), the components of the aqueous and non-aqueous composition must be selected to be non-irritating and safe under the usual circumstances. , and, of course, emulsifiers, humectants, perfumes and other usual depilatory additives present in either the aqueous or non-aqueous compositions must, of course, be compatible.
Det har vist sig, at der almindeligvis opnås tilfredsstillende resultater i overensstemmelse med opfindelsen, når et almindeligt, på vand baseret depilatorisk præparat, således som det er kendt for de fleste kosmetikkemikere, anvendes som det vandige præparat, og en dispersion af calciumoxid i en til gel omdannet mineraloliebasis indeholdende en emulgator såsom laurylalkoholethoxylat anvendes som det ikke-vandige præparat, hvorhos viskositeterne af de to præparater svarer så nært som muligt til hinanden.It has been found that generally satisfactory results are obtained in accordance with the invention when a common water-based depilatory composition, as is known to most cosmetic chemists, is used as the aqueous composition and a dispersion of calcium oxide in an aqueous solution. gel transformed mineral oil base containing an emulsifier such as lauryl alcohol ethoxylate is used as the non-aqueous composition, where the viscosities of the two compositions correspond as closely as possible to each other.
