Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
163 words
A fish treatment composition which comprises: (a) a phosphate mixture containing at least two of the following groups: (i) about 0% to about 95% of sodium pyrophosphate (-diphosphate), potassium pyrophosphate (-diphosphate), or a mixture thereof; (ii) about 14% to about 90% of sodium tripolyphosphate, potassium tripolyphosphate, or a mixture thereof; (iii) about 5% to about 50% of sodium hexametaphosphate, potassium hexametaphosphate or a mixture thereof, wherein said percentages are by weight based on the weight of the phosphate mixture, and said phosphate mixture has a statistical average content by weight of P 2 O 5 of about 47% to about 68%; and (b) a preservative consisting of potassium sorbate, sorbic acid or a mixture thereof, in an amount by weight of about 0.1 to about 0.2 parts per part of said phosphate mixture; and, (c) sufficient citric acid such that when said composition is present in a suitable liquid vehicle, a pH in the range of about 5.6 to about 6.5 is attained.
Claim 2
Dependent Claim
