Use of fragrance compositions for the prevention of the development of indole base malodours from fecal and urine based soils

Abstract

The present invention relates to the use of fragrance compositions, said fragrance compositions comprising fragrance compounds selected among: aldehydes, α,β-unsaturated aldehydes, alcohols, ketones, and mixtures thereof in any home and personal care product, each fragrance compound being able to restrict the formation of indole to less than 0.01 ppm (wt/wt) after 24 hours incubation at room temperature in an airtight sealed vessel of suitable fresh human urine containing 0.28% by weight of each fragrance compound in order to prevent the development of indole based malodours from faecal and urine based soils.

1 . A method of employing fragrance compositions, said fragrance compositions comprising fragrance compounds selected among: aldehydes, α,β-unsaturated aldehydes, alcohols, ketones, and mixtures thereof in any home and personal care product, each fragrance compound being able to restrict the formation of indole to less than 0.01 ppm (wt/wt) after 24 hours incubation at room temperature in an airtight sealed vessel of suitable fresh human urine containing 0.28% by weight of each fragrance compound, comprising preventing the development of indole based malodours from faecal and urine based soils. 
   
   
       2 . The method according to  claim 1 , wherein the fragrance composition comprises at least 2.5% to 100%, preferably 10% to 100%, more preferably 20% to 100% and even more preferably 40% to 100% by weight of fragrance compounds selected among aldehydes, α,β-unsaturated aldehydes, alcohols, ketones and mixtures thereof. 
   
   
       3 . The method according to  claim 1 , wherein the fragrance composition comprises 2.5% to 100%, preferably 10% to 100%, more preferably 20% to 100% and even more preferably 40% to 100% of fragrance compounds of fragrance compounds selected among aldehydes, α,β-unsaturated aldehydes and mixtures thereof. 
   
   
       4 . The method of  claim 1 , in which the aldehydes, α,β-unsaturated aldehydes, alcohols, ketones and mixtures thereof, do not decrease by no more than 60% by weight, preferably by no more than 30% by weight. 
   
   
       5 . A method of employing fragrance compositions containing 2.5% to 100% by weight of the fragrance compounds selected among acetophenone, aldehyde C-11, aldehyde C-10, benzaldehyde, benzophenone, cinnamic aldehyde, citronellal, citral, heliobouquet, trans 2-hexenal, trans 2-hexenol, perilla aldehyde, perilla alcohol, Veltol Plus or their mixtures, comprising inhibiting malodours containing an indole group when incorporated into any home or personal care product. 
   
   
       6 . A method of employing fragrance compositions containing 10% to 100% by weight of any of the fragrance compounds selected amongst acetophenone, aldehyde C-11, aldehyde C-10, benzaldehyde, benzophenone, cinnamic aldehyde, citronellal, citral, heliobouquet, trans 2-hexenal, trans 2-hexenol, perilla aldehyde, perilla alcohol, Veltol Plus or their mixtures, comprising inhibiting malodours containing an indole group when incorporated into any home or personal care product. 
   
   
       7 . A method of employing a fragrance composition as defined in  claim 1 , for fragrancing lavatory products such as rim blocks, cistern blocks and liquid rim blocks. 
   
   
       8 . A method of employing a fragrance composition as defined in  claim 1 , wherein the fragrance composition is in fibrous absorbent articles such as tampons, sanitary towels, babies' nappies, toddler pants, incontinence products and other devices intended for absorption of bodily excretions. 
   
   
       9 . A method of employing a fragrance composition as defined in  claim 1 , wherein the fragrance composition is in household cleaning products such as hard surface cleaners, soft furnishing cleaners, and room fresheners. 
   
   
       10 . A method of employing a fragrance composition as defined in  claim 1 , wherein the fragrance composition is incorporated in animal litter. 
   
   
       11 . A method of employing a fragrance composition as defined in  claim 1 , wherein the fragrance composition is in trigger spray cleaners for soft furnishings. 
   
   
       12 . A method of employing a fragrance composition as defined in  claim 1 , wherein the fragrance composition is in carpet cleaning products. 
   
   
       13 . A method of employing a compound selected among acetophenone, aldehyde C-11, aldehyde C-10, benzaldehyde, benzophenone, cinnamic aldehyde, citronellal, citral, heliobouquet, trans 2-hexenal, trans 2-hexenol, perilla aldehyde, perilla alcohol, Veltol Plus or their mixtures, comprising inhibiting indole. 
   
   
       14 . A method according to  claim 7 , for the preparation of a fragrance composition for preventing the development of indole based malodours from fecal and urine based soils.
