Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
32 words
An emulsifier blend comprising: 50-88% w/w C 14 -C 22 monoglyceride; 2-40% w/w C 14 -C 22 saturated fatty acid, 0-30% w/w C 14 -C 22 diglyceride, and 2-6% w/w ionic surfactant.
Claim 2
Dependent Claim
32 words
An emulsifier blend comprising: 50-88% w/w C 14 -C 22 monoglyceride; 2-40% w/w C 14 -C 22 saturated fatty acid, 0-30% w/w C 14 -C 22 diglyceride, and 2-6% w/w ionic surfactant.
Claim 3
Dependent Claim
43 words
An emulsifier blend as claimed in claim 1 in which the fatty acid is in the range 15-40% w/w and the diglyceride content is below 5% w/w and in which the total percent of fatty acid and diglyceride is at least 15% w/w.
Claim 4
Dependent Claim
42 words
An emulsifier blend as claimed in claim 1 in which the fatty acid is in the range 2-20% w/w and the diglyceride content is above 5% w/w and in which the total fatty acid and diglyceride content is at least 25% w/w.
Claim 5
Dependent Claim
22 words
A blend as claimed in claim 1 in which the ionic surfactant is a sodium or potassium soap of a fatty acid.
Claim 6
Dependent Claim
21 words
A blend as claimed in claim 4 in which the proportion of ionic surfactant present is between 4 and 6% w/w.
Claim 7
Dependent Claim
25 words
A blend as claimed in claim 1 in which the fatty acid or fatty acid groups are derived from a similar carbon length fatty acid.
Claim 8
Dependent Claim
52 words
A process for the preparation of a blend as claimed in claim 1 comprising heating together the requisite quantities of monoglyceride, fatty acid, diglyceride and ionic surfactant at a temperature and for a time sufficient to ensure the formation of a homogeneous melt and subsequently solidifying and optionally powdering the said melt.
Claim 9
Dependent Claim
27 words
A process as claimed in claim 8 in which the materials are heated together at a temperature of 80° -100° C for a period of 15-30 minutes.
Claim 10
Dependent Claim
18 words
An aqueous gel containing 20-40% w/w of a blend as claimed in claim 1 and 80-60% w/w water.
Claim 11
Dependent Claim
15 words
An aqueous gel as claimed in claim 9 containing 25-30% w/w of the emulsifier blend.
Claim 12
Dependent Claim
39 words
A process for the preparation of a gel as claimed in claim 9 comprising heating a well-stirred mixture of water and the emulsifier blend at a temperature between 50° and 75° C until a homogeneous liquid-crystalline dispersion is formed.
