water;

one or more surfactants; and

one or more rejuvenators of formula (X)

wherein:

each A is selected independently at each occurrence thereof from the group consisting of

 and

wherein at least one A is

each

 represents the point of attachment to a —CH 2 — group;

n is 1, 2, or 3;

R is selected from the group consisting of H, C 1 -C 23 alkyl, and benzyl, wherein the C 1 -C 23 alkyl can be optionally substituted with an aryl, heteroaryl, or heterocyclyl; or

R is selected from the group consisting of

each

 represents the point of attachment to a

 moiety;

R 1 , R 2 , and R 3 are independently selected from the group consisting of —H and —C(O)R 4 ;

R 4 is H, C 1 -C 23 alkyl, or aryl;

wherein the one or more rejuvenators of formula (X) have an N e value which is greater than about 1.0 and an N d value less than about N d,0 −1; and

wherein the components form an emulsion.

2. The emulsified coating product of claim 1 , wherein the one or more surfactants is selected from the group consisting of cationic emulsifying agents, anionic emulsifying agents, nonionic emulsifying agents, lecithin, and a combination thereof.

3. The emulsified coating product of claim 1 , wherein the one or more rejuvenators of formula (X) is sub-epoxidized soybean oil (SESO).

4. The emulsified coating product of claim 1 further comprising:

one or more binders.

5. The emulsified coating product of claim 4 , wherein the one or more binders is selected from the group consisting of bitumen, bio-asphalt, reclaimed asphalt shingles (RAS), plant oil binders, animal fat binders, maltenes, and a combination thereof.

6. The emulsified coating product of claim 1 further comprising:

one or more polymers.

7. The emulsified coating product of claim 6 , wherein the one or more polymers is selected from the group consisting of polyethylene, cross-linked polyethylene polypropylene, polybutadiene, polyisoprene, polyethylene terephthalate, polyvinyl alcohol, butyl acrylate, ethyl acrylate, methyl acrylate, poly(acrylated epoxidized triglycerides), and a combination thereof.

8. The emulsified coating product of claim 1 further comprising:

one or more colorants.

9. The emulsified coating product of claim 1 further comprising:

one or more antimicrobials.

10. The emulsified coating product of claim 1 further comprising:

one or more stabilizing or gelling agents.

11. The emulsified coating product of claim 1 further comprising:

one or more crosslinkers.

12. The emulsified coating product of claim 1 further comprising:

one or more antistripping agents.

13. The emulsified coating product of claim 1 further comprising:

one or more wetting agents.

14. A method of treating an asphalt roofing system comprising:

contacting the asphalt roofing system with the emulsified coating product of claim 1 .

15. The emulsified coating product of claim 6 , wherein the one or more polymers is one or more copolymers.
