Claims17
A pharmaceutical composition comprising a extracellular Arenicola marina hemoglobin immobilized and stable in a physiologically acceptable hydrocolloid network, said hydrocolloid network forms a three-dimensional network defining pores, the pores forming a first population of large pores and a second population of pores wherein the size of the pores in the second population of pores is about 10 nm, without the release of the hemoglobin immobilized in said hydrocolloid network being greater than 10%, wherein the Arenicola marina hemoglobin is not crosslinked, and wherein the hemoglobin is contained in the second population of pores.
A cosmetic composition comprising extracellular Arenicola marina hemoglobin immobilized and stable in a physiologically acceptable hydrocolloid network, said hydrocolloid network forms a three-dimensional network defining pores, the pores forming a first population of large pores and a second population of pores wherein the size of is the pores in the second population of pores is about 10 nm, without the release of the hemoglobin immobilized in said hydrocolloid network being greater than 10%, wherein the Arenicola marina hemoglobin is not crosslinked, and wherein the hemoglobin is contained in the second population of pores.
A composition comprising extracellular Arenicola marina hemoglobin immobilized in a gelled hydrocolloid network, wherein
- the hydrocolloid network comprises from 0% to 98% by weight of water, and a first population of large pores and a second population of pores wherein the pores in the second population of pores have a size of about 10 nm;
- and
- the Arenicola marina hemoglobin is contained in the second population of pores;
- not crosslinked;
- and
- wherein the hemoglobin is present in an amount of about 0.1% w/w to about 60% w/w relative to the total dry weight of the hemoglobin and the hydrocolloid network.
