Description
Vaskemiddelblanding med regulert skumming. Detergent mixture with regulated foaming.
Oppfinnelsen vedrører en vaskemiddelblanding med regulert skumming. Slike produkter egner seg for bruk i vaskemaskiner som ikke tolererer stort skumvolum. Slike skum-intolerante vaskemaskiner er f.eks. vaskemaskiner av trommeltypen med ilegg på front eller topp. The invention relates to a detergent mixture with regulated foaming. Such products are suitable for use in washing machines that do not tolerate a large volume of foam. Such foam-intolerant washing machines are e.g. drum-type washing machines with inserts on the front or top.
Det er velkjent at syntetiske vaskemidler med høy skummeevne, slik de brukes i vaskemaskiner av skovletypen, ikke kan brukes i It is well known that synthetic detergents with a high foaming capacity, as used in bucket-type washing machines, cannot be used in
vaskemaskiner av trommeltypen, på grunn av overskumming. Ut fra de innarbeidede høyt-skummende vaskemidler er det utviklet vaskemidler som har regulert skumme-evne og hvor vaskemiddelkomponenten består av en spesiell blanding av syntetiske vaskemidler, f.eks. en blanding av anioniske og ikke-ioniske syntetiske vaskemidler og såpe som drum-type washing machines, due to over-foaming. Based on the incorporated high-foaming detergents, detergents have been developed that have regulated foaming ability and where the detergent component consists of a special mixture of synthetic detergents, e.g. a mixture of anionic and nonionic synthetic detergents and soap that
gir produktet de ønskede lavtskummende egenskaper. Beroende på gives the product the desired low-foaming properties. Depending on
typen og mengdeforholdene av disse komponenter kan man få lavt- the type and quantity ratio of these components, low-
eller middelsskummende produkter. or medium-foaming products.
En syntetisk vaskemiddelblanding med regulert skumme-evne A synthetic detergent mixture with regulated foaming ability
består normalt av et høytskummende, anionisk syntetisk vaskemid- normally consists of a high-foaming, anionic synthetic detergent
del sammen med en skum-undertrykker, f.eks. såpe, et ikke-ionisk syntetisk vaskemiddel eller en blanding av disse. part together with a foam suppressor, e.g. soap, a non-ionic synthetic detergent or a mixture of these.
Bruken av hydrofober, f.eks. hydrokarboner, er også blitt foreslått i lavtskummende vaskemiddelblandinger av denne type. The use of hydrophobic, e.g. hydrocarbons, have also been proposed in low-foaming detergent compositions of this type.
Imidlertid er det, selv i kategorien vaskemaskiner av However, it is, even in the category of washing machines of
trommeltype stor variasjon med hensyn til skum-toleranse. En syntetisk vaskemiddelblanding som egner jseg for bruk i en trommel-vaskemaskin som er ganske skum-tolerant, kan produsere for stort skumvolum i en vaskemaskin som er mer intolerant, hvorved skummet strømmer over. Videre har variasjoner i vannets hårdhet, type og grad av tilsmussing, såvel som vaske-temperaturen innvirkning på skumme-evnen. drum type large variation with regard to foam tolerance. A synthetic detergent mixture suitable for use in a drum washing machine that is fairly suds tolerant may produce excessive suds volume in a more intolerant washing machine, causing the suds to overflow. Furthermore, variations in the hardness of the water, type and degree of soiling, as well as the washing temperature have an impact on the foaming ability.
Videre er det meget ønskelig at et lavtskummende produkt produserer en akseptabel skum-mengde ved lave temperaturer, dvs. i området fra 20°C og opp til ca. 60°c, og denne mengde bør ikke øke med økende temperaturer. Et lavtskummende vaskemiddel bør ha et akseptabelt skum til å begynne med ved lavere temperaturer i vaske-prosessen, dvs. opp til ca. 60°C, og bør være lavtskummende ved høyere temperaturer, dvs. over ca. 80°c. Furthermore, it is highly desirable that a low-foaming product produces an acceptable amount of foam at low temperatures, i.e. in the range from 20°C and up to approx. 60°c, and this amount should not increase with increasing temperatures. A low-foaming detergent should initially have an acceptable foam at lower temperatures in the washing process, i.e. up to approx. 60°C, and should be low-foaming at higher temperatures, i.e. above approx. 80°c.
Det bør videre produsere en merkbar skum-mengde i vaskemaskiner med skovler eller skovlhjul, såvel som ved manuell vask i et fat. Syntetiske vaskemiddelblandinger som hittil er kjent, gir enten en merkbar skum-mengde i vaskemaskiner med skovler eller skovlhjul og ved manuell vasking i fat, men skummer over i vaskemaskiner av trommel-typen, eller de er lavtskummende og skummer ikke over i vaskemaskiner av trommel-typen, men skummer ikke i vaskemaskiner med skovler eller skovlhjul og ved manuell vasking i fat. It should also produce a noticeable amount of suds in washing machines with paddles or paddle wheels, as well as when manually washing in a tub. Synthetic detergent mixtures known to date either produce a noticeable amount of foam in washing machines with paddles or paddle wheels and in manual washing in tubs, but foam over in drum-type washing machines, or they are low-foaming and do not foam over in drum-type washing machines. type, but does not foam in washing machines with paddles or paddle wheels and when manually washing in tubs.
De syntetiske vaskemiddelblandinger med regulert skumming som The synthetic detergent mixtures with controlled foaming which
er kjent fra teknikkens stand, og som inneholder skum-undertryk- is known from the prior art, and which contains foam-suppression-
kende midler, har vist seg å gi en tydelig skum-undertrykkelse ved lave og middels temperaturer, noe som, som forklart ovenfor, er uønsket i en syntetisk vaskemiddelblanding med regulert skumme-evne. known agents, have been shown to give a clear foam suppression at low and medium temperatures, which, as explained above, is undesirable in a synthetic detergent mixture with regulated foaming ability.
Det er nå overraskende funnet at eri lavtskummende vaskemiddelblanding med regulert skumming over hele temperaturområdet i vaskecyklusen i en trommel-vaskemaskin og som produserer en merkbar skum-mengde i en vaskemaskin med skovler eller skovlhjul og ved manuell vasking i fat, kan oppnåes ved at det til en vaskemiddelblanding som inneholder 2-20 vekt% av et anionisk syntetisk vaskemiddel og 1-10 vekt% av et ikke-ionisk syntetisk vaskemiddel og/ eller 1-10 vekt% såpe, tilsettes en forbindelse av den generelle formel: It has now surprisingly been found that a low-foaming detergent mixture with regulated foaming over the entire temperature range of the washing cycle in a drum washing machine and which produces a noticeable amount of foam in a washing machine with paddles or paddle wheels and when manually washing in a drum, can be achieved by adding a detergent mixture containing 2-20% by weight of an anionic synthetic detergent and 1-10% by weight of a non-ionic synthetic detergent and/or 1-10% by weight of soap is added to a compound of the general formula:
hvor R er en forgrenet eller rettkjedet alifatisk hydrokarbon- where R is a branched or straight-chain aliphatic hydrocarbon-
rest med 8-24 karbonatomer som kan være umettet, eller en acylamidrest med 8-24 karbonatomer, residue with 8-24 carbon atoms which may be unsaturated, or an acylamide residue with 8-24 carbon atoms,
Rl er -C2H2_'R1 is -C2H2_'
n er et tall fra 1 til 25, og n is a number from 1 to 25, and
M er hydrogen eller et kation. M is hydrogen or a cation.
Eksempler på egnede forbindelser i henhold til oppfinnelsen er eterkarboksylsyrer eller deres alkali- eller jordalkali-metall-salter, spesielt deres natrium-, kalium-, kalsium-, magnesium-, amin-og alkylolamin-salter med ovennevnte generelle formel, hvor R er en alkyl- eller alkenylgruppe med fra 12 til 18 karbonatomer. Eksempler på disse er forbindelser hvor R er en alkylgruppe med 12 karbonatomer og n er 2,5, 4,5, 10, 15 og 25. videre kan R være en alkylgruppe med 18 karbonatomer og n = 2 eller 5, og R kan være oleyl og n = 6, eller forbindelser hvor R er en kokosfettsyreamid-rest og n = 3, 4 eller 5. Examples of suitable compounds according to the invention are ether carboxylic acids or their alkali or alkaline earth metal salts, especially their sodium, potassium, calcium, magnesium, amine and alkylolamine salts of the above general formula, where R is a alkyl or alkenyl group with from 12 to 18 carbon atoms. Examples of these are compounds where R is an alkyl group with 12 carbon atoms and n is 2.5, 4.5, 10, 15 and 25. Furthermore, R can be an alkyl group with 18 carbon atoms and n = 2 or 5, and R can be oleyl and n = 6, or compounds where R is a coconut fatty acid amide residue and n = 3, 4 or 5.
Man må være klar over at disse eksempler ikke begrenser oppfinnelsen. Andre forbindelser med den ovennevnte generelle formel kan også brukes i overensstemmelse med oppfinnelsen. It must be understood that these examples do not limit the invention. Other compounds of the above general formula may also be used in accordance with the invention.
Vaskemiddelblandingene ifølge oppfinnelsen har regulert skumme-evne, dvs. at de produserer en merkbar skummengde ved lavere temperaturer og er lavtskummende ved høyere temperaturer, som forklart tidligere. De produserer et mer balansert skum ved alle temperaturer, uten at skummet strømmer over ved høye temperaturer. De er videre også overraskende godt egnet i andre typer vaskemaskiner, f.eks slike som har skovler eller skovlhjul, og for manuell vasking i fat. The detergent mixtures according to the invention have regulated foaming ability, i.e. they produce a noticeable amount of foam at lower temperatures and are low-foaming at higher temperatures, as explained earlier. They produce a more balanced foam at all temperatures, without the foam overflowing at high temperatures. They are also surprisingly well suited in other types of washing machines, for example those with paddles or paddle wheels, and for manual washing in tubs.
Alkyl- eller alkylarylpolyeterkarboksylsyrene i henhold til oppfinnelsen er kjent fra teknikkens stand, nemlig fra U.S. patent nr. 2.183.853. De fremstilles f.eks. ved reaksjon mellom de tilsvarende polyglykoleter-alkoholer med alkalimetallhydroksyd og et The alkyl or alkylaryl polyether carboxylic acids according to the invention are known from the prior art, namely from U.S. Pat. patent No. 2,183,853. They are produced e.g. by reaction between the corresponding polyglycol ether alcohols with alkali metal hydroxide and et
alkalimetallsalt av kloreddiksyre. alkali metal salt of chloroacetic acid.
Utvelgelsen av den riktige forbindelse: i henhold til oppfinnelsen kan lett gjøres ved å bestemme HLB-verdien til syreforbind-elsen ifølge kjente metoder. The selection of the correct compound: according to the invention can be easily done by determining the HLB value of the acid compound according to known methods.

Vaskemiddelblandingen ifølge oppfinnelsen inneholder også byggesalter og vanlig benyttede vaskemiddelbestanddeler. The detergent mixture according to the invention also contains building salts and commonly used detergent ingredients.
Den aktive, syntetiske vaskemiddelblanding omfatter et anio- The active, synthetic detergent mixture comprises an anionic
nisk, syntetisk vaskemiddel og et ikke-ionisk syntetisk vaskemiddel og/eller såpe. De anioniske, syntetiske vaskemidler er velkjente på vaskemiddelområdet. Eksempler på disse er alkylsulfater med 8 nic, synthetic detergent and a non-ionic synthetic detergent and/or soap. The anionic, synthetic detergents are well known in the detergent field. Examples of these are alkyl sulfates with 8

Den aktive, syntetiske vaskemiddelblanding omfatter videre et ikke-ionisk, syntetisk vaskemiddel og/eller såpe. The active, synthetic detergent mixture further comprises a non-ionic, synthetic detergent and/or soap.
De ikke-ioniske, syntetiske vaskemidler er velkjente på området. Eksempler på disse er kondensasjonsproduktene av alkylenoksyd, f.eks. etylenoksyd eller propylenoksyd eller blandinger av disse med alkoholer med fra 10 - 26 karbonatomer, f.eks. fettalkoholer, med mono-eller dialkylfenoler med fra 8-20 karbonatomer i alkylkjeden, med fettsyreamider, polyalkylenglykoler og blandede alkylenoksyd-addukter, alkoksylerte sukkerfettsyre-estere osv. The nonionic synthetic detergents are well known in the art.

Såpene som kan brukes i henhold til oppfinnelsen, er alkali- The soaps that can be used according to the invention are alkali-
eller jordalkalimetallsaltene av fettsyrer med fra 10 til 24 karbonatomer eller derivater av disse. Eksempler på disse er de velkjente såper, f.eks. natrium-såpene som stadig brukes for regulering av skum, f.eks. såper fra palmeolje, herdét fiskeolje, herdet talg, kokosnøttolje osv. or the alkaline earth metal salts of fatty acids with from 10 to 24 carbon atoms or derivatives thereof. Examples of these are the well-known soaps, e.g. the sodium soaps that are still used to regulate foam, e.g. soaps from palm oil, hardened fish oil, hardened tallow, coconut oil, etc.

For middels-skummende ønskes vanligvis fra 8-15%, og for lavtskummende er 2-9% vanligvis passende. Videre, hvis produktene inneholder et ikke-ionisk syntetisk vaskemiddel, er vanligvis fra 1-10% av dette passende, mens det foretrukne område for middels-skummende er 1-8% og for lavtskummende 2-10%. Hvis produktene inneholder såpe, kan den anvendte såpemengde være 1-10%, for middels-skummende formål 1-6% og for lavtskummende formål 5-10%. Prosent-tallene er i vekt av hele produktet. Generally, as mentioned, the products according to the invention contain from 2-20% of an anionic synthetic detergent. For medium-foaming, 8-15% is usually desired, and for low-foaming, 2-9% is usually appropriate. Furthermore, if the products contain a non-ionic synthetic detergent, usually from 1-10% of this is suitable, while the preferred range for medium-foaming is 1-8% and for low-foaming 2-10%. If the products contain soap, the amount of soap used can be 1-10%, for medium-foaming purposes 1-6% and for low-foaming purposes 5-10%. The percentage figures are by weight of the entire product.
Den gjenværende del av produktet kan bestå av de normale komponenter i et syntetisk vaskemiddel. Vanligvis kan de omfatte fra 20-60% alkalimetall-kondenserte fosfater, f.eks. natriumtripolyfos-fat, natriumpyrofosfat, natriumtrimetafosfat osv. Om ønskes kan en del av det alkalimetall-kondenserte fosfat erstattes med et sekves-teringsmiddel, f.eks. etylendiamintetraeddiksyre eller nitriltri-eddiksyre eller andre organiske sekvesteringsmidler. The remaining part of the product may consist of the normal components of a synthetic detergent. Typically they may comprise from 20-60% alkali metal condensed phosphates, e.g. sodium tripolyphosphate, sodium pyrophosphate, sodium trimetaphosphate, etc. If desired, part of the alkali metal condensed phosphate can be replaced with a sequestering agent, e.g. ethylenediaminetetraacetic acid or nitrile triacetic acid or other organic sequestering agents.

Fluorescerende midler, parfyme, mattingsinhibitorer, teksti1-ødeleggelsesinhibitorer, blekeaktiva-torer, fyllstoffer, f.eks. natriumsulfat, alkalier, f.eks. ortofos-fater, germicider osv. kan også anvendes i produktene ifølge oppfinnelsen . If desired, for laundry purposes, sodium perborate can also be added in an amount of up to 45%. Fluorescent agents, perfume, matting inhibitors, texture destruction inhibitors, bleach activators, fillers, e.g. sodium sulfate, alkalis, e.g. orthophosphates, germicides etc. can also be used in the products according to the invention.
Man må være klar over at produktene ifølge oppfinnelsen ikke bare egner seg for bruk i vaskemaskiner av trommeltypen, f.eks. slike som oppvarmes fra kaldt til koketemperatur, men også i andre typer vaskemaskiner hvor det kreves regulert skumming. De egner seg også for manuell vasking. One must be aware that the products according to the invention are not only suitable for use in drum-type washing machines, e.g. those that are heated from cold to boiling temperature, but also in other types of washing machines where regulated foaming is required. They are also suitable for manual washing.
Oppfinnelsen skal i det følgende belyses ved hjelp av eksempler. I tegningene betyr en bølget linje (■— -) overskumming. In the following, the invention will be illustrated by means of examples. In the drawings, a wavy line (■— -) means overfoaming.
