Definitions
- the invention relates to cold water emulsifiable agents based on castor oil derivatives, oil bodies and magnesium soaps, emulsions containing these agents, a process for the preparation of these emulsions and the use of the agents for the preparation of emulsions.
- Oil bodies with high or low polarity can only be satisfactorily emulsified with water and emulsifiers of the type mentioned if metal soaps are present. However, since these can only be worked into the fat phase when hot, the advantage in terms of energy and time savings in cold emulsification is lost.
- a manufacturer of cosmetic or pharmaceutical emulsions who intends to use very polar or very nonpolar oil bodies has therefore been forced to melt the fat phase (oil + emulsifier + optionally co-emulsifier) at temperatures around 100 ° C., the stabilizer enter and then add the aqueous phase.
- the object of the invention was therefore to provide the manufacturer of emulsions with a means which can be emulsified in the cold with water, optionally with the addition of a further oil phase, the complex step of hot emulsification being thus reliably avoided can.

- Suitable diol esters of the formula (Ic) are, for example, ethylene glycol dioleate, ethylene glycol diotridecanoate, propylene glycol di (2-ethylhexanoate), propylene glycol diisostearate, propylene glycol dipelargonate, butanol diisostearate and neopentyl glycol dicaprylate.
- Branched primary alcohols such as those known under the name "Guerbet alcohols” ⁇ cf. A.J. O'Lennick et al., Soap Cosm.Chem.Spec. 52 (1987) ⁇ are known. Typical examples are 2-butyl octanol, 2-hexyl decanol or 2-0 octyl decanol, and also esters of Guerbet alcohols with long-chain aliphatic carboxylic acids, in particular stearic acid. Finally, so-called Guerbet carbonates come into consideration, as are described in German patent application DE-Al 40 40 154 (Henkel).
- the proportion of the oil bodies in the agents according to the invention can usually make up 30 to 80 and preferably 60 to 70% by weight.
- Magnesium soaps (component c) are substances which follow the formula (Ha) and / or (IIb)
