Definitions
- the invention relates to a clear, liquid, at temperatures of 10 to 35 ° C. stable emulsifier concentrate based on sterols and / or wool wax alcohols and branched, saturated alcohols with 16 to 20 carbon atoms.
- Sterols and wool wax alcohols are known auxiliaries for the production of cosmetic and pharmaceutical preparations.
- they are used for the production of water-in-oil and oil-in-water emulsions, which are commercially available, for example, in the form of creams.
- Commercial emulsifier concentrates which contain sterols or wool wax alcohols in a carrier consisting of paraffin oil are frequently used to produce such preparations.
- such concentrates are cloudy at normal temperature and must be stirred and heated evenly before further processing.
- the emulsifier concentrates according to the invention are in a clear, liquid form in a wide temperature range from 10 to 35 ° C. This means a considerable improvement over the conventional emulsifier concentrates based on sterols or wool wax alcohols in a mineral oil carrier, since the latter products are only in a clear form at higher temperatures.
- the stars to be used according to the invention are steroids in which there is a hydroxyl group on the third carbon atom of the steroid structure and which are therefore chemically attributable to the alcohols.
- the steroids occur in all animal and plant cells. According to their occurrence, they are divided into zoosterols, for example cholesterol, and phytosterols, which are predominantly found in higher plants.
- wool wax alcohols are understood to mean complex mixtures of sterols and aliphatic alcohols from wool wax.
- Suitable branched, saturated alcohols (B) are 2-hexyldecanol, 2-0ctyldodecanol or other branched, saturated alcohols having 16 to 20 carbon atoms.
- e.g. 2- Hexyldecanol which is sold by the applicant under the name Eutanol G 16.
- those emulsifier concentrates according to the invention in which the alcohol (B) is 2-octyldodecanol and are marketed by the applicant under the name Eutanol G are particularly well suited.
- the emulsifier concentrates according to the invention can advantageously be used for the production of cosmetic or pharmaceutical preparations. They are particularly suitable for the preparation of preparations in the form of emulsions, preferably of the water-in-oil type.
- the cosmetic or pharmaceutical emulsions produced on the basis of the emulsifier concentrates according to the invention are distinguished in particular by good storage stability. Storage stability means that after several months of storage the emulsions show no signs of separation or creaming and that the consistency is almost unchanged; This means in particular that the viscosity of the emulsions based on the emulsifier concentrates according to the invention remains approximately constant in the course of storage.

- compositions and the turbidity behavior of the emulsifier concentrates EK 1 and EK 2 according to the invention and the comparisons EK 3 and EK 4 are summarized in Table 1.
- This table shows that the concentrates according to the invention are in clear, liquid form over a wide temperature range, while the commercial comparisons in this range are only available in cloudy form.
- Water-in-oil emulsions were prepared on the basis of concentrates EK 1 to EK 3, the compositions of which can be found in Table 2.
- the emulsifier concentrates, co-emulsifiers, oils and consistency agents were combined at room temperature and heated to 75 ° C. with stirring. Water and the other auxiliaries were then introduced at this temperature with stirring. The emulsions thus obtained were cooled to about 35 ° C. and homogenized by further stirring. After further cooling to 20 ° C 93/02660
- Viscosity of examples B1 and B3 according to the invention and comparisons VI and V2 measured using a Brookfield viscometer (Helipath) using spindle C at 5 rpm. The emulsions were then stored at room temperature for 12 weeks and the viscosities were determined again. The results of these measurements are summarized in Table 3.
- Table 3 shows that the viscosity of the water-in-oil emulsions based on the emulsifier concentrates according to the invention changes over the course of the 93/02660 8 -
