## Abstract

Disclosed are stable liquid products as consisting essentially of at least one finely dispersed physiologically tolerated fat-soluble substance as disperse phase; glycerol or glycerol mixed with water as continuous phase; and esters of ascorbic acid with long-chain fatty acids as an emulsifier and stabilizer.

## Claims

### Claim 1

A stable liquid product consisting essentially of:
a) from 1 to 50% by weight, based on the liquid product, of at least one physiologically tolerated fat-soluble substance selected from vitamin A, D, E or K or derivatives thereof, carotenoids and glycerides of polyunsaturated fatty acids,
b) from 99 to 50% by weight, based on the product, of glycerol or glycerol/water in the ratio from 100:0 to 50:50, and
c) from 0.2 to 5% by weight, based on the products, of esters of ascorbic acid with fatty acids of from 16 to 18 carbons.

### Claim 2 (depends on 1)

A stable liquid product as defined in claim 1, wherein the physiologically tolerated fat-soluble substances have particle sizes below 5 .mu.m.

### Claim 3 (depends on 1)

A stable liquid product as defined in claim 1, wherein the fat-soluble substance selected is a carotenoid which is .beta.-carotene and said .beta.-carotene is present in an amount of from 1-20% by weight, based on the liquid product.
