Multi-Phase Personal Care Composition Comprising a Stabilizing Perfume Composition

Abstract

A method of stabilizing a multiphase composition is described. The composition comprises a structured surfactant phase, a benefit phase and a perfume comprising perfume raw materials. The method comprises a step of selecting at least 70% of the perfume raw materials that have a ClogP of greater than 1.8.

1 . A method of stabilizing a multiphase composition comprising a structured surfactant phase, a benefit phase and perfume comprising perfume raw materials; said method comprising the step of selecting at least 70%, by weight of said perfume, of said perfume raw materials having a ClogP of greater than 1.8. 
   
   
       2 . The method of  claim 1  wherein at least 80% of said perfume raw materials have a ClogP of greater than 1.8. 
   
   
       3 . The method of  claim 1  wherein at least 85% of said perfume raw materials have a ClogP of greater than 1.8. 
   
   
       4 . The method of  claim 1  wherein at least 90% of said perfume raw materials have a ClogP of greater than 1.8. 
   
   
       5 . The method of  claim 1  wherein at least 95% of said perfume raw materials have a ClogP of greater than 1.8. 
   
   
       6 . The method of  claim 1  further comprising the step of incorporating a preservative into said multiphase composition wherein said preservative is substantially free of formaldehyde. 
   
   
       7 . The method of  claim 6  wherein said preservative comprises less than 0.01% formaldehyde. 
   
   
       8 . A multiphase personal care composition comprising a structured surfactant phase, a benefit phase and perfume comprising perfume raw materials; wherein at least 70%, by weight of said perfume, of said perfume raw materials have a Clog P less greater than 1.8. 
   
   
       9 . The multi-phase, personal care composition of  claim 8 , wherein said personal care composition is selected from the group consisting of a skin care lotion, a bar soap, a body wash, a shampoo, conditioner, a in-shower body moisturizer and mixtures thereof. 
   
   
       10 . The multi-phase, personal care composition of  claim 8 , wherein said benefit phase has a Consistency Value (K) of from about 30 to about 350 Pa-s. 
   
   
       11 . The multi-phase, personal care composition of  claim 8 , wherein said structured surfactant phase is visually distinct from said benefit phase. 
   
   
       12 . The multi-phase, personal care composition of  claim 11  wherein said structured surfactant phase and benefit phase form a pattern. 
   
   
       13 . The multi-phase, personal care composition of  claim 12 , wherein said pattern is selected from the group consisting of striped, geometric, marbled, and combinations thereof. 
   
   
       14 . A personal care composition comprising a structured surfactant phase, a benefit phase, a preservative, and perfume comprising perfume raw materials; said preservative being substantially free of formaldehyde; wherein at least 70%, by weight of said perfume, of said perfume raw materials have a Clog P greater than 1.8. 
   
   
       15 . The personal care composition of  claim 18 , wherein said 95% of said perfume raw materials have a Clog P greater than 1.8. 
   
   
       16 . The personal care composition of  claim 18 , wherein said structured surfactant phase is visually distinct from said benefit phase. 
   
   
       17 . A personal care composition comprising a structured surfactant phase, a benefit phase and perfume comprising perfume raw materials; wherein less than 30%, by weight of said perfume, of said perfume raw materials are selected from the group consisting of benzaldehyde dimethyl acetal, benzaldehyde glyceryl acetal, cinnamic alcohol, cinnamic aldehyde dimethyl acetal, cis-3-hexenal, diethyl malonate, dihydro coumarin, ethyl butanoate, ethyl methyl dioxolane acetate (2-Me, 1,3-dioxol-2-acet.), ethyl vanillin—see 4-hydroxy 3-ethoxybenzaldehyde, heliotropine dimethyl acetal, hexanol (2-, 3-), hexenol (all isomers), hexenone (1-hexen-3-one, 4-hexen-3-one, 5-hexen-2-one)), hexyl cinnamate, hydrocinnamic aldehyde, hydrocinnamyl alcohol, hydroquinone, hydroquinone monomethyl ether, linalool oxide, methyl phenylacetate, nonenal (all isomers), o-anisaldehyde & m- & p- also, phenethyl alcohol, phenoxyacetaldehyde, phenylacetaldehyde ethyleneglycol acetal, prenyl acetate, propylene glycol, sinensal, triethyl citrate, valeraldehyde, valeric acid, valerolactone, vanillic acid, vanillin acetate, vanillin isobutyrate, vanillyl alcohol, vanillylidene acetone and mixtures thereof. 
   
   
       18 . The personal care composition of  claim 17 , wherein said composition is multiphase. 
   
   
       19 . The personal care composition of  claim 17  wherein said personal care composition further comprises a preservative wherein said preservative being substantially free of formaldehyde. 
   
   
       20 . The personal care composition of  claim 17 , wherein said personal care composition is selected from the group consisting of a skin care lotion, a bar soap, a body wash, a shampoo, conditioner, a in-shower body moisturizer and mixtures thereof.
