Abstract
An improved foamable protein hydrolysate based concentrate is provided containing multivalent cations and a water soluble polymer, which remains stable in storage for at least six months and which, when diluted with 10 to 50 parts of water and mixed with air to generate a foam, produces a foam which lasts essentially unchanged for at least three days.
Claims24
A foamable concentrate composition comprising 300 to 900 parts protein hydrolysate, 15 to 60 parts of a metal based salt;
- 5 to 50 parts of a polysaccharide polymer selected from the group consisting of xanthan gum, algin, scleroglucan, welan gum, gellan gum, gum arabic, gum tragacanth, carrageenan, rhamson gum, and polysaccharide PS-7, and a combination of said polymers;
- 1-30 parts of an imbibing agent;
- and 10 to 40 parts of a cosolvent in which the polymer is essentially insoluble;
- which concentrate remains stable in storage for at least six months and which when diluted with 10 to 50 parts of water produces a foam which lasts for at least three days.
A foamable concentrate composition which remains stable in storage for at least six months and which when diluted with 10 to 50 parts of water produces a foam which lasts for at least three days, comprising the following ingredients in the percentages indicated by weight:
- ______________________________________ protein hydrolysate 40-80 ammonium hydroxide 0-5 hexylene glycol 0-4 sodium lignosulfonate 0-10 ferrous chloride (29% sol) 6-18 N-methyl-2-pyrrolidone 1.5-3.5 xanthan gum 1.5-3.5 ammonium thiocyanate 1-3 ______________________________________
A method for making a foamable concentrate composition comprising 300 to 900 parts protein hydrolysate, 15 to 60 parts of a metal based salt and 5 to 50 parts of a polysaccharide polymer, which concentrate remains stable in storage for at least six months and which, when diluted with 10 to 50 parts of water and mixed with air to generate a foam, produces a foam which lasts essentially unchanged for at least three days, which method comprises the following steps:
- a) first mixing the metal based salt with the protein hydrolysate;
- and
- b) combining the mixture obtained in a) above with a suitable imbibing agent prior to adding the polymer.
