Composition
The present invention provides a stabilising composition, comprising: a) a first phenolic antioxidant comprising one or more phenolic compounds having the structure of formula (I): wherein R 1 is a linear or branched alkyl group having from 12 to 20 carbon atoms; and b) one or more second phenolic antioxidants independently selected from: a mono-hydroxybenzene having lower steric hindrance than the first phenolic antioxidant; a di-hydroxybenzene; and/or a tri-hydroxybenzene.
1. A stabilizing composition, comprising:
a) a first phenolic antioxidant comprising one or more phenolic compounds having the structure of formula (I):
wherein R 1 is a linear or branched alkyl group having from 12 to 20 carbon atoms; and
b) one or more second phenolic antioxidants comprising
a di-hydroxybenzene comprising 4-tert-butylcatechol, benzene-1,2-diol, or benzene-1,3-diol.
2. The stabilizing composition of claim 1 , wherein the di-hydroxybenzene comprises 4-tert-butylcatechol or benzene-1,2-diol.
3. The stabilizing composition of claim 1 , wherein the di-hydroxybenzene comprises benzene-1,2-diol.
4. The stabilizing composition of claim 1 , wherein the di-hydroxybenzene comprises 4-tert-butylcatechol.
5. The stabilizing composition of claim 1 , wherein the one or more second phenolic antioxidants is present in an amount of from about 1 to about 50 wt. %, based on the total weight of the stabilizing composition.
6. The stabilizing composition of claim 1 , wherein the one or more second phenolic antioxidants are present in the stabilizing composition in an amount of from about 1 to about 35 wt. %, based on the total weight of the stabilizing composition.
7. The stabilizing composition of claim 1 , wherein the one or more second phenolic antioxidants are present in the stabilizing composition in an amount of from about 5 to about 30 wt. %, based on the total weight of the stabilizing composition.
8. The stabilizing composition of claim 1 , wherein the one or more second phenolic antioxidants are present in the stabilizing composition in an amount of from about 10 to about 25 wt. %, based on the total weight of the stabilizing composition.
9. A stabilized composition, comprising:
a) a polyol and/or a polyurethane; and
b) a stabilizing composition of claim 1 .
10. The stabilized composition of claim 9 , wherein the polyol is present and comprises a polyether polyol and/or a polyester polyol.
11. The stabilized composition of claim 9 , wherein the polyol is present with the polyurethane, and comprises a polyether polyol and/or a polyester polyol.
12. The stabilized composition of claim 9 , wherein the polyurethane is present and comprises a polyurethane foam.
13. The stabilized composition of claim 9 , wherein the amount of stabilizing composition is present from about 0.01 to about 10% by weight of the polyol and/or a polyurethane.
14. The stabilized composition of claim 9 , wherein the amount of stabilizing composition is present from about 0.01 to about 5%, by weight of the polyol and/or a polyurethane.
15. The stabilized composition of claim 9 , wherein the amount of stabilizing composition is present from about 0.01 to about 2%, by weight of the polyol and/or a polyurethane.
16. The stabilizing composition of claim 1 , wherein the stabilizing composition does not contain a benzofuranone-based booster component.
17. The stabilizing composition of claim 1 , wherein the stabilizing composition does not contain an amine-containing antioxidant.
