Air and fabric freshener
The present invention relates to a stable, aqueous freshener composition for the reduction or elimination of malodors in air and on fabrics. The composition comprises from about 0.1% to about 3.0% by weight, hydrogen peroxide as a malodor oxidant; an effective level of undecylenic acid (and/or derivative thereof) as a malodor absorber preblended with a fragrance; a surfactant to solubilize the fragrance/malodor absorber blend; an acid based stabilizer in a range from about 0.008% to about 0.60% by weight; an optional pH buffer; and an aqueous carrier. The composition can be delivered via a spray dispenser for treatment of indoor air and fabrics. The composition has a pH of less than about 6 and does not contain ingredients known to soil, stain or damage fabrics. When applied as a fine mist, the composition delivers effective control of a broad range of malodors, while remaining imperceptible on surfaces when dry.
1. A freshener composition for air and fabric, comprising:
hydrogen peroxide in a range from about 0.1 to about 3.0 wt. %; a premix of fragrance and ethyl or methyl undecylenate in a range from about 0.5 to about 2.5% wt. %; a surfactant in a % wt. range from about 0.1 to about 7.5 wt.; an acid based stabilizer in a range of about 0.008 to 0.0765 wt. %; and a quantity of water sufficient to bring total to 100 wt. % wherein said fragrance is compatible with said hydrogen peroxide.
2. The composition of claim 1 , wherein said surfactant is nonionic.
3. The composition of claim 2 , wherein said nonionic surfactant is an ethoxylated sorbitan ester.
4. The composition of claim 3 , wherein said ethoxylated sorbitan ester is polysorbate 20 (PEG-20 Sorbitan Laurate).
5. The composition of claim 1 , wherein said acid based stabilizer is a phosphorus based acid or salt.
6. The composition of claim 5 , wherein said phosphorus based acid is phosphoric acid and phosphonates.
7. The composition of claim 1 , wherein said water is deionized water.
8. The composition of claim 1 , further comprising a pH buffer system.
9. The composition of claim 8 , wherein said pH buffer system is citric and sodium citrate.
10. The composition of claim 9 , wherein said citric acid and sodium citrate is in a range of about 1 part citric acid to 2-3 parts sodium citrate.
11. The composition of claim 8 , wherein the total amount of buffer system employed in the freshener composition is between about 0.2 to 0.4 wt. % based on the weight of the composition.
12. The composition of claim 1 , wherein said composition has a shelf stability of at least one year.
