Abstract

Biomolecular conjugates are provided which comprise the conjugation product of a repeat sequence protein polymer and at least one active agent. Additional aspects provide methods for their manufacture and various industrial and consumer applications.

Claims (21)

1. Biomolecular conjugates comprising the conjugation product of a repeat sequence protein polymer comprising SEQ ID NO. 19 and at least one active agent, wherein the at least one active agent is selected from the group consisting of: silicones, fragrances, dyes, tints, UV active agents, sunscreens, lanolin, vitamins, bleaches, thickening agents, enzymes, antimicrobials, preservatives, and combinations thereof.

2. The biomolecular conjugates as recited in claim 1 , wherein the at least one active agent comprises a silicone.

3. The biomolecular conjugates as recited in claim 2 , wherein the silicone is selected from the group consisting of: silicones comprising an epoxy functional group, polydimethyl siloxanes, silicone resins, silicone surfactants, alkyl modified silicones, gum-silicone fluid blends, phenyl silicone fluids, dimethyl silicone fluids, quaternized ammonium salts of suitable silicones, silicones comprising one or more amino functional groups, and combinations thereof.

4. A personal care composition comprising the biomolecular conjugates as recited in claim 1 with a carrier or excipient.

5. The personal care composition as recited in claim 4 wherein the composition is a hair care composition, a skin care composition, a nail care composition, a cosmetic composition, an oral care composition, or an over-the-counter pharmaceutical composition.

6. The personal care composition as recited in claim 4 wherein the biomolecular conjugates comprise from about 0.001% to about 10% by weight of the composition.

7. The personal care composition as recited in claim 4 wherein the biomolecular conjugates comprise from about 0.01% to about 5% by weight of the composition.

8. The personal care composition as recited in claim 4 wherein the biomolecular conjugates comprise from about 0.01% to about 1% by weight of the composition.

9. A process for making a personal care composition comprising combining a biomolecular conjugate with an acceptable carrier or excipient to obtain a personal care composition, wherein the biomolecular conjugate comprises a conjugation product of a repeat sequence protein polymer comprising SEQ ID NO. 19 and at least one active agent, wherein the at least one active agent is selected from the group consisting of: silicones, fragrances, dyes, tints, UV active agents, sunscreens, lanolin, vitamins, bleaches, thickening agents, enzymes, antimicrobials, preservatives, and combinations thereof.

10. A method of producing a biomolecalar conjugate comprising a fusion protein conjugate comprising a conjugation product of a repeat sequence protein polymer comprising SEQ ID NO. 19 and at least one active agent selected from the group consisting of: silicones, fragrances, dyes, tints. UV active agents, sunscreens, lanolin, vitamins, bleaches, thickening agents, enzymes, antimicrobials, preservatives, and combinations thereof, the method comprising:

selecting the repeat sequence protein polymer and the active agent suitable for a desired application;

obtaining a gene encoding the repeat sequence protein polymer and a gene encoding the at least one active agent; constructing a conjugate gene from the gene encoding the repeat sequence protein polymer and the gene encoding the at least one active agent comprising a protein or peptide;

expressing the conjugate gene to form an expression product comprising the fusion protein conjugate; fermenting the expression product comprising the fusion protein conjugate; and purifying the fusion protein conjugate.

11. The method as recited in claim 10 comprising at least two active agents.

12. The method as recited in claim 10 wherein the at least one active agent comprises a protein or a peptide comprising an antimicrobial peptide, a UV active agent, a cotton binding peptide, green fluorescent protein, or a combination thereof.

13. A repeat sequence protein polymer comprising the biomolecular conjugate as recited in claim 1 .

14. Biomolecular conjugates comprising the conjugation product of a repeat sequence protein polymer having the sequence SEQ. ID NO. 19 and at least one active agent selected from the group consisting of silicones, fragrances, dyes, tints, UV active agents, sunscreens, lanolin, vitamins, bleaches, thickening agents, enzymes, antimicrobials, preservatives, and combinations thereof.

15. The biomolecular conjugates as recited in claim 14 , wherein the at least one active agent comprises a silicone.

16. The biomolecular conjugates as recited in claim 14 , wherein the silicone is selected from the group consisting of: silicones comprising an epoxy functional group, polydimethyl siloxanes, silicone resins, silicone surfactants, alkyl modified silicones, gum-silicone fluid blends, phenyl silicone fluids, dimethyl silicone fluids, quaternized ammonium salts of suitable silicones, silicones comprising one or more amino functional groups, and combinations thereof.

17. A personal care composition comprising the conjugation product of a repeat sequence protein polymer having the sequence SEQ. ID NO. 19; at least one active agent selected from the group consisting of silicones, fragrances, dyes, tints, UV active agents, sunscreens, lanolin, vitamins, bleaches, thickening agents, enzymes, antimicrobials, preservatives, and combinations thereof; and a cater or excipient.

18. The personal care composition as recited in claim 17 wherein the composition is a hair care composition, a skin care composition, a nail care composition, a cosmetic composition, an oral care composition, or an over-the-counter pharmaceutical composition.
