Description

The invention is in the field of cosmetics and relates to the use of 1,3-propylene glycol for lowering, adjusting and / or correcting the viscosity of mild, surfactant-poor cleaning agents. The invention further relates to a mild cosmetic cleanser which contains, in addition to special anionic and amphoteric / zwitterionic surfactants, at least one cationic care polymer and 1,3-propylene glycol.

Due to the addition of a variety of different active ingredients and excipients, it is often necessary in the production of cosmetic cleaning agents, such as shower gels or hair shampoos, to adjust the viscosity again and / or correct. A content of surfactants and salts in cosmetic cleaners is usually sufficient to achieve a satisfactory viscosity of the compositions. The preparation of cleaning compositions with lower surfactant contents and / or a high proportion of mild, usually less foamy surfactants, however, usually requires the addition of additional thickeners. This can lead to undesirably high viscosities of the cleaning agents, which must be corrected. The mixture of several batches of detergents of different viscosity and / or the addition of water are not useful, especially for very large batches. In the past, therefore, 1,2-propylene glycol was usually used to reduce too high viscosities in surfactant-containing agents.

In WO 2010/015247 the production of shampoo concentrates has been described in which short-chain diols, preferably 1,3-butylene glycol and / or 1,2-propylene glycol were used to reduce the viscosity.

However, the addition of 1,3-butylene glycol and / or 1,2-propylene glycol sometimes resulted in an undesirable shift in the properties of the shampoos. In particular, the foaming and / or care properties of cosmetic cleaners which have been diluted with the aforementioned diols have not always been satisfactory.

It is an object of the present application to find active substances and / or methods by means of which the viscosity, in particular of mild cosmetic cleansing compositions, can be lowered without adversely affecting the foaming or care properties of the compositions.

It has now surprisingly been found that the use of 1,3-propylene glycol is particularly suitable for reducing or adjusting the viscosity of mild detergents. In particular, the dilution of surfactant-poor systems containing less than 25% by weight (preferably mild) surfactants was possible without significant change in the cosmetic properties of the agents.

The use of 1,3-propylene glycol to adjust the viscosity of mild detergents containing a maximum of 25 wt .-% surfactants leads to particularly mild and foamy compositions having satisfactory viscosity. "Mild and high-foaming" compositions are understood to mean detergents which ensure high amounts of foam, rapid foaming and / or very good haptic properties of the foam. The foam properties are associated with excellent care properties (such as low irritation of (head) skin, softness and suppleness of the skin and / or hair).

A first subject of the invention is therefore the use of 1,3-propylene glycol for lowering, adjusting and / or correcting the viscosity of mild detergents which, by weight, contain less than 25% by weight of surfactant (s).

"Cleaning agents" are preferably understood cosmetic cleansers such as shower and bath preparations, face and body cleansers and hair shampoos.

Detergents suitable according to the invention preferably contain a cosmetically acceptable carrier, which may preferably be aqueous or aqueous-alcoholic. Preferably, the cosmetic carrier contains at least 50 wt .-%, more preferably at least 60 wt .-% and particularly preferably at least 70 wt .-% water. Furthermore, the cosmetic carrier may contain 0.01 to 50% by weight, preferably 0.05 to 40% by weight and in particular 0.1 to 30% by weight of at least one alcohol which may be selected from ethanol, ethyl diglycol, 1-propanol, 2-propanol, isopropanol, 1,2-propylene glycol, glycerol, diglycerol, triglycerol, 1-butanol, 2-butanol, 1,2-butanediol, 1,3-butanediol, 1-pentanol, 2-pentanol, 1,2-pentanediol, 1,5-pentanediol, 1, hexanol, 2-hexanol, 1,2-hexanediol, 1,6-hexanediol, polyethylene glycols, sorbitol, sorbitan, benzyl alcohol, phenoxyethanol or mixtures of these alcohols.

Preference is given to the water-soluble alcohols. Particularly preferred are ethanol, ethyl diglycol, 1-propanol, 2-propanol, isopropanol, 1,2-propylene glycol, glycerol, benzyl alcohol and / or phenoxyethanol and mixtures of these alcohols.

1,3-propylene glycol is particularly suitable as a diluent of mild detergents which - based on their weight - a maximum of 25 wt .-%, more preferably at most 20 wt .-%, more preferably 17.5 wt .-% and most preferably at most 15 Wt .-% surfactant (s) included.

An arbitrarily strong dilution of cleaning agents is not desirable in terms of application technology. Particularly suitable cleaning agents have a final viscosity in the range of 4.500 to 15,000 mPas (measured at 20 ° C with a Brookfield viscometer, 20 rpm, spindle 5).

In a first preferred embodiment of the use according to the invention, the mild detergents after dilution with 1,3-propylene glycol therefore preferably have a viscosity in the range from 4.500 to 15,000 mPas, more preferably from 5,000 to 12,500 mPas, particularly preferably from 5,500 to 10,000 mPas and in particular from 6,000 to 9,000 mPas (measured at 20 ° C with Brookfield, 20 rpm, spindle 5).

In order to achieve an optimal balance between mildness, care and good foam properties of cleaning agents, in addition to the maximum amount of surfactant and the selection of the surfactant types and the weight ratios of surfactants is important. Particularly mild and high-foaming detergents can be prepared, for example, by using certain anionic and amphoteric or zwitterionic surfactants.

• b) 1,00 bis 10,00 Gew.-% mindestens eines milden zwitterionischen und/oder amphoteren Tensids, und

The table shows that the mild shampoo A to which 0.50 weight percent of 1,3-propylene glycol was added can be diluted more effectively than an identical composition to which equal amounts of 1,2-propylene glycol have been added.
