Description

30th

The invention relates to cosmetic detergents containing paraffin oil in the form of liquid, clearer, more stable solutions.

It is Z. B. from Fette, Seifen, Anstrichmittel 64 (1962), p. 854, and from Seifen, öle, Fette, Wachse 89 (1963), S. 899, known that commercial washing raw material combinations, z. B. alkylbenzenesulfonates or fatty alcohol ether sulfates, In bubble bath and shampoo settings, too strong degreasing on the surface of the skin works. By adding large amounts of over-greasy substances to the washing-active substance one can remedy this disadvantage. There is also a possibility in the over-greasy substance To dissolve perfume oils and vitamins (e.g. oil-soluble derivatives of pantothenic acid) and in this way. to be supplied to the skin.

In order to emulsify these over-greasy substances in the washing water, the mixture customary emulsifiers, mostly fatty alcohol polyglycol ethers, are also added. It is still an advantage an addition of fatty acid amide polyglycol ethers, which increases the absorption of the fatty acids oils promoted through the skin.

Oils that have an excessively greasy effect are neutral oils, e.g. B. peanut oil, wheat germ oil or olive oil, in use. These oils have a number of disadvantages; they tend to go rancid and have an annoying effect Intrinsic smell. As natural products, they also come in varying quality; because of this is the The formulation of the detergent is subject to constant changes. Above all, the amount and type of suitable one Emulsifiers have to be determined experimentally every time the oil quality changes.

The paraffin oil, which is widely used in modern cosmetics, does not suffer from these disadvantages. It is Always available in the same, cosmetically harmless quality (DAB-6 goods), odorless, water-clear and can be stored indefinitely. Besides, it's cheap.

Mixtures, which mainly consist of detergent substances, paraffin oil, fatty alcohol polyglycol ethers as well as fatty acid amide polyglycoi ethers are in fact effective, skin-friendly personal cleansing agents The production of liquid aqueous, concentrated and clear mixtures of this type prepares however, great difficulty. If you stir the components together, a cloudy mixture is created, which will soon split up into two phases.

The invention is based on the object of making the mixtures described liquid, clear, practical to process unlimited stable solutions.

According to the invention, this object is achieved by a mixture of

a) 5 to 20 percent by weight, preferably 7.5 to 15 percent by weight, n-alkylbenzenesulfonate (sodium salt or triethanolamine salt),

b) 15 to 35 percent by weight of paraffin oil, optionally mixed with other cosmetically useful ones oil,

c) 3 to 8 percent by weight of fatty acid amide polyglycol ethers,

dj 10 to 25 percent by weight, preferably 15 to

23 percent by weight, fatty alcohol polyglycol ether with 3 to 8 moles of ethylene oxide,

e) optionally 1 to 3 percent by weight of perfume oil,

f) optionally 1 to 5 percent by weight of vitamin extract,

g) 3 to 8 percent by weight of a glycol or glycol ether and

h) 15 to 35 percent by weight of water

as a further component 1 to 6 percent by weight, preferably 2 to 4 percent by weight, NaCl and / or KCl admits.

To produce the clear solutions, the components are first stirred without NaCl or KCl with each other and then transfers the resulting cloudy mixture by adding NaCl and / or KCl into a clear solution. This solution is practically indefinitely stable; it can be stored without difficulty, sent, packaged and used for their intended purpose.

30 parts paraffin oil (DAB 6),
5 parts of fatty acid amide polyglycol ether,

15 parts of a fatty alcohol mixture reacted with 4 to 6 moles of ethylene oxide,
8 parts of lauryl alcohol, which had been reacted with 4 moles of ethylene oxide,
5 parts of diethylene glycol monoethyl ether and

24 parts of water

are intensively stirred together; the result is a thick, cloudy mixture, which after some agreement Hours begins to separate into two phases. The mixture is stirred again and 3 parts of table salt are added; after brief stirring results in a clear, liquid, stable solution. (After several months of storage it is no turbidity or segregation occurred.)
