Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 119 words
A method of removing hair from whole carcasses, skins, hides and pelts comprising (1) applying to the carcass, skin, hide and pelt an effective amount of a composition comprising: ______________________________________ Approx. Wt. (%) ______________________________________ Water 78.00-94.00 Alkali Hydroxide 2.00-6.00 Alkali Gluconate 0.10-0.50 Trisodium Phosphate 1.00-3.00 Triethanolamine Lauryl Sulfate or 0.50-2.00 Sodium Lauryl Sulfate or both Cocodiethanolamide 0.05-0.10 Sodium Metasilicate 0.50-0.20 Alkali, alkaline Earth or 0.45-5.00 Ammonium Thioglycolate or a combination thereof Triethanolamine Dodecyl Benzene 0.50-1.50 Sulfonate Alkaline Earth Hydroxide 1.00-4.00 ______________________________________ (2) leaving the composition in contact with the hair to be removed for predetermined period of time at a predetermined temperature; and (3) rinsing the composition and unwanted hair from the carcass, skin, hide or pelt with water.
