Description
Fremgangsmåte til fremstilling av små oljeholdige kapsler. Process for the production of small oily capsules.
Foreliggende oppfinnelse angår små The present invention relates to small
oljeholdige kapsler av gelert hydrofilt kolloidmateriale hvor hver kapsel inneholder en dråpe av en væske, slik som olje, som ikke er blandbar med vann, samt en fremgangsmåte til fremstilling av slike. oily capsules of gelled hydrophilic colloidal material where each capsule contains a drop of a liquid, such as oil, which is not miscible with water, as well as a method for producing such.
Spesielt består foreliggende oppfinnelse i en forbedring og modifikasjon av en slik kapsel som er beskrevet i patent nr. 87 953, hvilket beskriver forskjellige frem-gangsmåter til fremstilling av små oljeholdige kapsler av hydrofilt kolloidmateriale hvor det dannes en emulsjon av oljen og en vandig sol av et gelerbart hydrofilt kolloid, hvoretter det bevirkes koaservering, således at det hydrofile materiale bringes til å avsette seg omkring og inneslutte de enkelte dråper av oljen, idet det kolloide materiale deretter geleres, og om nødven-dig, herdes. In particular, the present invention consists in an improvement and modification of such a capsule which is described in patent no. 87 953, which describes different methods for the production of small oil-containing capsules of hydrophilic colloidal material where an emulsion of the oil and an aqueous sol of a gelable hydrophilic colloid, after which coamination is effected, so that the hydrophilic material is caused to settle around and enclose the individual drops of the oil, the colloidal material then being gelled and, if necessary, hardened.
Filmer eller membraner fremstilt av hydrofilt kolloidmateriale som er blitt Films or membranes prepared from hydrophilic colloidal material which has become
gelert, for eksempel slike som utgjør kap-selveggene, er sammensatt av et nettverk av lange molekyler hvor det i de resul-terende kanaler eller porer tilbakeholdes en mengde vann som varierer, alt etter strukturens tetthet. Nærvær av de vann-holdige kanaler eller porer, kan under visse betingelser slippe gjennom fluidum slik gelled, for example those that make up the capsule walls, are composed of a network of long molecules where an amount of water is retained in the resulting channels or pores that varies, depending on the density of the structure. The presence of the water-containing channels or pores can, under certain conditions, allow fluid to pass through like this
som damp og væske, alt etter den forskjellige kraft som er til stede på de forskjellige sider av filmen. I kapsler som har vegger fremstilt av slikt materiale og som hol-der en væske som ikke er blandbar med vann, kan disse porer by på en anledning for den inneholdte væske å unnslippe på as vapor and liquid, according to the different force present on the different sides of the film. In capsules which have walls made of such material and which hold a liquid which is not miscible with water, these pores may provide an opportunity for the contained liquid to escape
grunn av sitt damptrykk eller på grunn av nærvær av væske på utsiden av en kapsel, hvilke skaffer den nødvendige aktivitet for å trekke ut det væskemateriale som ikke er blandbart med vann, eller begge omstendigheter virker sammen. because of its vapor pressure or because of the presence of liquid on the outside of a capsule, which provide the necessary activity to extract the liquid material which is not miscible with water, or both circumstances act together.
Hensikten med foreliggende oppfinnelse er å gjøre kapselveggen mere ugjen-nomtrengelig. The purpose of the present invention is to make the capsule wall more impenetrable.
Ifølge foreliggende oppfinnelse hind-res en slik gjennomtrengning av den inneholdte væske eller gjennomtrengning av en ytre væske eller damp ved å anordne en film av etylcellulose mellom den inne-lukkede væske og den hydrofile kolloidale vegg. According to the present invention, such penetration of the contained liquid or penetration of an external liquid or vapor is prevented by arranging a film of ethyl cellulose between the enclosed liquid and the hydrophilic colloidal wall.
Oppfinnelsen består i en fremgangsmåte til fremstilling av små oljeholdige kapsler som har en sperrefilm av etylcellulose som er dannet mellom overfalten av oljedråpene og den gelerte kolloide vegg, som er fremstilt av en emulsjon av oljen og en vandig sol av et gelerbart hydrofilt kolloid, hvoretter det fremkalles koaservering således at molekylene i det hydrofile kolloide materiale avsetter seg omkring og inneslutter de enkelte oljedråper, idet det kolloidale materiale deretter geleres, og hvor etylcellulose er oppløst i oljen før koaserveringen, hvorved en etyl-cellulosefilm dannes under fremgangsmåten mellom oljedråpene og det hydrofile kolloide materiale. The invention consists in a method for the production of small oily capsules which have a barrier film of ethyl cellulose formed between the envelope of the oil droplets and the gelled colloidal wall, which is prepared from an emulsion of the oil and an aqueous sol of a gelable hydrophilic colloid, after which the Coamination is induced in such a way that the molecules in the hydrophilic colloidal material settle around and enclose the individual oil droplets, the colloidal material then gels, and where ethyl cellulose is dissolved in the oil before the coamination, whereby an ethyl cellulose film is formed during the process between the oil droplets and the hydrophilic colloid material.
Det finnes flere forskjellige måter å utføre foreliggende oppfinnelse på og en utførelse vil bli beskrevet i det følgende. En emulsjon fremstilles av 20 g gum-miarabicum oppløst i 160 g vann og 80 g triklordifenyl hvori er oppløst fra 0,2 til 10 g etylcellulose med lav viskositet, idet) den nevnte etylcellulose har et etoksylinn-hold på ca. 47,5 vektspst., og viskositeten, er 4 centipoises når det er dispergert :tørt! i en 5 vektpst. konsentrasjon i en 80/20 toluenetanol oppløsning ved 25° C. Denne emulgering fortsettes inntil den ønskede dråpestørrelse er nådd, for eksempel 5 mi-kron, idet fremgangsmåten utføres ved ca. 50° C. Før og under emulgeringen skal pH-verdien for systemet reguleres til mellom . 6 og 7. Emulsjonen tilsettes under omrø-ring 20 g. svinelærgelatin oppløst i 150 g vann, idet gelatinen fortrinnsvis har sitt isoelektriske punkt ved ca. pH 8. Emulsjonen blir deretter fortynnet under om-røring inntil koaservering av .de kolloide molekyler er påbegynt, og dette punkt be-regnes i fravær av olje ved uklarhetsvirk-ning av oppløsningen som beskrevet i ho-vedpatentet. Under denne fortynning, mu-ligens på grunn av nærvær av den vandige fase i systemet som omgir oljedråpene og etylcellulosens affinitet til vann, utskilles etylcellulosen fra oppløsningen og utfelles på flaten mellom hver dråpe og den om-givende vandige omgivelse og danner en film hvorpå de første molekyler av det hydrofile .kolloide materiale avsetter seg på .grunn av koaservering. De molekylære komplekser kan på grunn av omrøring ikke avsette seg av tyngdekraften, hvilket de ellers ville gjøre, men avsetter seg istedet omkring de enkelte olj edråper, hvilket resulterer i et le-geme hvor etylcellulosefilmen er omgitt av en flytende vegg av gelerbart komplekst kolloid materiale. Etter at det komplekse materiale praktisk talt fullstendig har •avsatt seg, helles systemet i en stor mengde vann ved 0° C, og omrøres for å gjøre systemet ensartet, hvilket resulterer i at de flytende vegger blir gelert og avsetter .seg i fast tilstand. There are several different ways of carrying out the present invention and one embodiment will be described in the following. An emulsion is prepared from 20 g of gum miarabicum dissolved in 160 g of water and 80 g of trichlorodiphenyl in which is dissolved from 0.2 to 10 g of low-viscosity ethyl cellulose, the said ethyl cellulose having an ethoxylin content of approx. 47.5% by weight, and the viscosity is 4 centipoises when dispersed :dry! in a 5 wt. concentration in an 80/20 toluene ethanol solution at 25° C. This emulsification is continued until the desired droplet size is reached, for example 5 microns, the method being carried out at approx. 50° C. Before and during the emulsification, the pH value for the system must be adjusted to between . 6 and 7. 20 g of pig's leg gelatin dissolved in 150 g of water is added to the emulsion while stirring, the gelatin preferably having its isoelectric point at approx. pH 8. The emulsion is then diluted with stirring until coalescence of the colloidal molecules has begun, and this point is calculated in the absence of oil by the clouding effect of the solution as described in the main patent. During this dilution, possibly due to the presence of the aqueous phase in the system surrounding the oil droplets and the affinity of the ethyl cellulose for water, the ethyl cellulose separates from the solution and precipitates on the surface between each droplet and the surrounding aqueous environment, forming a film on which the first molecules of the hydrophilic .colloidal material are deposited on .due to coaservation. Due to agitation, the molecular complexes cannot settle by gravity, which they would otherwise do, but instead settle around the individual oil droplets, which results in a body where the ethyl cellulose film is surrounded by a liquid wall of gelable complex colloidal material . After the complex material has practically completely settled, the system is poured into a large amount of water at 0° C, and stirred to homogenize the system, resulting in the liquid walls being gelled and deposited in a solid state.
Etter gelering av kapslene kan de herdes ved at det i systemet under kontinuer-lig omrøring helles 19,8 g av 37 vektspst.ig vandig oppløsning av formaldehyd, idet systemet er regulert til mellom pH 9 og pH 1,1, og omrøringen forutsettes i en time eller mere ved ca. 3° C. Kapslene er nå fullstendig dannet og kan .anvendes i det resterende vandige system eller skilles fra dette ved filtrering, sentrifugering, for-støvningstørkning og lignende. After the capsules have gelled, they can be hardened by pouring 19.8 g of a 37% by weight aqueous solution of formaldehyde into the system under continuous stirring, the system being regulated to between pH 9 and pH 1.1, and stirring is assumed in an hour or more at approx. 3° C. The capsules are now completely formed and can be used in the remaining aqueous system or separated from this by filtration, centrifugation, spray drying and the like.
Det skal forstås at 'Også andre stoffer som ikke er blandbare med vann enn triklordifenyl kan innkapsles på liknende imåte, slik som alle typer animalske, vegetabilske og mineraloljer og modifiserte syntetiske oljer, slik som fluorinerte hy-drokarboner. Blant slike oljer kan nevnes blivenolj e, kokosnøttolj e, castorolj e, sperm - ■ olje, vesentlig vegetabilske oljer, petrole-umsmøreolje og mere flyktige fraksjoner av petroleum, og syntetisk olje slik som metylsalicylat. It should be understood that 'Also other substances which are not miscible with water than trichlorodiphenyl can be encapsulated in a similar way, such as all types of animal, vegetable and mineral oils and modified synthetic oils, such as fluorinated hydrocarbons. Among such oils can be mentioned blivenol oil, coconut oil, castor oil, sperm oil, essential vegetable oils, petroleum lubricating oil and more volatile fractions of petroleum, and synthetic oil such as methyl salicylate.
Blant erstatninger for de polymere stoffer kan nevnes alubumin, alginater, casein, agar-agar, stivelse, pektiner og Irish moss, idet slike velges parvis således at både negative og amfotære polymere anvendes sammen og således at minst én er gelerbar. Den negative og amfotære natur for de parvise polymere molekyler tillater dannelse av koaserverte legemer under riktige betingelser slik som angitt i den foretrukne utførelse. Substitutes for the polymeric substances include albumin, alginates, casein, agar-agar, starch, pectins and Irish moss, these being chosen in pairs so that both negative and amphoteric polymers are used together and so that at least one is gelable. The negative and amphoteric nature of the paired polymeric molecules allows the formation of coasorbed bodies under the right conditions as indicated in the preferred embodiment.
Det er et stort område for etylcellulosematerialet å velge blant med hensyn til viskositet, idet den nevnte viskositet på 4 centipoises, under de angitte betingelser er særlig egnet til fremstillingen slik som beskrevet, men dette kan varieres fra en lavere viskositet og opp til 10 centipoises, idet etylcellulosematerialet velges med hensyn på etoksyinnholdet i overensstem-melse med det vannublandbare fluidum som anvendes, da noen har mere oppløs-ende virkning på etylcellulosen enn andre. There is a large range for the ethyl cellulose material to choose from with regard to viscosity, as the aforementioned viscosity of 4 centipoises, under the specified conditions, is particularly suitable for the production as described, but this can be varied from a lower viscosity and up to 10 centipoises, the ethyl cellulose material being selected with regard to the ethoxy content in accordance with the water-immiscible fluid used, as some have a more dissolving effect on the ethyl cellulose than others.
