Dryer-added fabric treatment article of manufacture containing antioxidant and sunscreen compounds for sun fade protection of fabrics
| Details |
Inventors: Severns, John C.;
Assignee: The Procter & Gamble Company (Cincinnati, OH)
Primary Examiner: Lieberman; Paul
Assistant Examiner: Tierney; Michael
Attorney, Agent or Firm: Lewis; Beth Goldstein, Zea; Betty J.
The present invention relates to a dryer-added fabric treatment article of manufacturing to reduce the fading of fabrics from sunlight comprising: I. a composition comprising: A. from about 5% to about 75%, by weight of the composition, of a sun- fade protection active selected from the group consisting of: i. a non-fabric staining, light stable, antioxidant compound preferably containing at least one C.sub.8 -C.sub.22 hydrocarbon fatty organic moiety; ii. a non-fabric staining, light stable, sunscreen compound; and iii. mixtures thereof, B. from about 10% to about 95% by weight of the composition of a fabric conditioning compound; and II. a substrate, on which said composition is attached, which provides for release of an effective amount of said sun-fade protection active and said fabric conditioning compound onto fabrics in an automatic laundry dryer at automatic laundry dryer operating temperatures; wherein said antioxidant compound is a solid having a melting point of less than about 80.degree. C., or a liquid at a temperature of less than about 40.degree. C.; and wherein said sunscreen compound absorbs light at a wavelength of from about 290 nm to about 450 nm and is a solid compound having a melting point of from about 25.degree. C. to about 90.degree. C., or a viscous liquid at a temperature of less than about 40.degree. C. |

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dryer-added fabric treatment article of manufacture to reduce the fading of fabrics from sunlight comprising: I.
a composition comprising: A.
from about 5% to about 75%, by weight of the composition, of a sun- fade protection active selected from the group consisting of: i.
a non-fabric staining, light stable, antioxidant compound preferably containing at least one C.
sub.
8 -C.
sub.
22 hydrocarbon fatty organic moiety; ii.
a non-fabric staining, light stable, sunscreen compound; and iii.
mixtures thereof; B.
from about 10% to about 95% by weight of the composition of a fabric conditioning compound; and II.
a substrate, on which said composition is attached, which provides for release of an effective amount of said sun-fade protection active and said fabric conditioning compound onto fabrics in an automatic laundry dryer at automatic laundry dryer operating temperatures; wherein said antioxidant compound is a solid having a melting point of less than about 80.
degree.
C.
, or a liquid at a temperature of less than about 40.
degree.
C.
; and wherein said sunscreen compound absorbs light at a wavelength of from about 290 nm to about 450 nm and is a solid compound having a melting point of from about 25.
degree.
C.
to about 90.
degree.
C.
, or a viscous liquid at a temperature of less than about 40.
degree.
C.
SUN-FADE PROTECTION ACTIVE The present invention relates to a dryer-added fabric treatment article of manufacture to reduce the fading of fabrics from sunlight comprising a sun-fade protection active.
Said sun-fade protection active is selected from the group consisting of a non-fabric staining, light stable antioxidant compound preferably containing at least one C.
sub.
8 -C.
sub.
22 hydrocarbon fatty organic moiety, a non-fabric staining, light stable sunscreen compound, and mixtures thereof.
Said sun-fade protection active is present at a level of from about 5% to about 75%, preferably from about 15% to about 60%, more preferably from about 25% to about 50%, by weight of the total composition
