Description
Die Erfindung betrifft ein Mittel zum Bleichen von pflanzlichen Farbstoffen, insbesondere auf menschlicher Haut.The invention relates to an agent for bleaching vegetable dyes, in particular on human skin.
Die menschliche Haut wird durch pflanzliche Farbstoffe oft so stark verfärbt, daß die Verfärbung auch durch noch so intensive Seifenwaschungen nicht entfernt werden kann. Eine Beseitigung kann dann nur durch eine starke mechanische Einwirkung, z.B. durch Scheuern mittels Sand o.dgl., herbeigeführt werden, wobei jedoch die versteckter liegenden Hautteile, beispielsweise an den Fingernägeln, Hautrillen, unberührt bleiben. Im Haushalt ist es bekannt, daß die durch Gemüseputzen, Kartoffelschälen u.dgl. Arbeiten verursachten Verfärbungen der Hand durch Behandlung mit Zitronensaft bis zu einem gewissen Grade beseitigt werden können.The human skin is often so strongly discolored by vegetable dyes that the discoloration cannot be removed even by intensive soap washes. Removal can then only be brought about by a strong mechanical action, e.g. by rubbing with sand or the like. However, the more hidden parts of the skin, for example on the fingernails, skin grooves, remain unaffected. In the household it is known that hand discolouration caused by cleaning vegetables, peeling potatoes and the like can be removed to a certain extent by treatment with lemon juice.
Es wurde nun gefunden, daß pflanzliche Farbstoffe insbesondere auf menschlicher Haut durch ein Mittel gebleicht werden können, das aus einer Mischung von Natriumbisulfat und Natriumsulfit, vorzugsweise im Verhältnis 10 : 1, besteht.It has now been found that vegetable dyes, in particular on human skin, can be bleached by an agent which consists of a mixture of sodium bisulfate and sodium sulfite, preferably in a ratio of 10: 1.
Erfindungsgemäß können auch dem Natriumsulfit andere Salze beigemischt sein, deren Lösung einen pH-Wert von unter 4 aufweist.According to the invention, other salts, the solution of which has a pH value of less than 4, can also be added to the sodium sulfite.
Eine besonders gute Wirkung wird erzielt, wenn das Mittel aus einer Mischung von unterschwefligsauren und schwefligsauren Salzen besteht und zwar infolge der bei der Handhabung des Mittels auf der Haut auftretenden schwefligen Säure.A particularly good effect is achieved if the agent consists of a mixture of hyposulphurous and sulphurous salts as a result of the sulphurous acid that occurs on the skin when the agent is handled.
Beispiele:Examples:
Als Entfärbemittel auf der Haut findet eine Mischung von 10 Teilen Natriumbisulfat, 1 Teil Natriumsulfit und 10 Teilen eines indifferenten Trägermaterials Verwendung.A mixture of 10 parts of sodium bisulfate, 1 part of sodium sulfite and 10 parts of an inert carrier material is used as a decolorizing agent on the skin.
Anstelle von Natriumsulfat können andere Salze, deren Lösung einen pH-Wert von unter 4 besitzt, Verwendung finden, so z.B. anderesInstead of sodium sulphate, other salts, the solution of which has a pH value below 4, can be used, e.g. other salts
saures schwefelsaures Alkali,acidic sulfuric acid alkali,
saures schwefligsaures Alkali undacidic sulphurous alkali and
primäres phosphorsaures Alkali,primary phosphoric acid alkali,
fernerfurther
ameisensaures Aluminium,formic aluminum,
essigsaures Aluminium,acetic aluminum,
schwefelsaures Aluminiumsulfuric aluminum
und deren basische Salze.and their basic salts.
