PARTICLES HAVING A HIGH LOAD OF FRAGRANCE OR FLAVOR OIL
The present invention relates to (preferably spray-dried) particles having a high load of fragrance (perfume) or flavor oil, a process for their preparation, its use for perfuming and/or flavoring products and products comprising such particles.
1 . A particle containing a fragrance and/or flavor oil, the particle comprising:
(a) 50-80 wt % fragrance and/or flavor oil,
(b) 5 to 25 wt % modified starch,
(c) 5 to 25 wt % of one or more mono alkaline metal phosphate salts,
(d) 0-10 wt % of one or more additional ingredients,
wherein the weight percent values are based on the total dry weight of the particle.
2 . The particle according to claim 1 comprising:
(a) 55-78 wt % fragrance and/or flavor oil, and/or
(b) 10-25 wt % chemically modified starch, and/or
(c) 5-15 wt % of monosodium and/or monopotassium phosphate and/or
(d) 0-5 wt % of one or more additional ingredients,
wherein the weight percent values are based on the total dry weight of the particle.
3 . The particle according to claim 2 comprising:
(a) 60-75 wt % fragrance or flavor oil,
(b) 15-22 wt % of chemically modified starch,
(c) 8-12 wt % of monosodium phosphate and
(d) 0-5 wt % additional ingredients.
4 . The particle according to claim 1 having:
(i) a particle size equal to or less than 300 microns, and/or
(ii) a residual water content equal to or less than 3 wt %, and/or
(iii) an amount of surface oil of equal to or less than 4 wt %,
wherein all weight percent values are based on the total dry weight of the particles.
5 . The particle according to claim 4 having:
(i) an average particle size in the range of 5 to 125 microns, and/or
(ii) a residual water content in the range of 0.1 to 2.5 wt %, and/or
(iii) an amount of surface oil of less than 3 wt %,
wherein all weight percent values are based on the total dry weight of the particles.
6 . A process for producing the particles according to claim 1 comprising the steps:
(i) forming a mixture comprising the following constituents (a) through (e)
(a) 20-56 wt % fragrance and/or flavor oil,
(b) 2 to 17.5 wt % modified starch,
(c) 2 to 17.5 wt % of one or more mono alkaline metal phosphate salts,
(d) 0-7 wt % of one or more additional ingredients and
(e) 30-60 wt % of water,
in each case based on the total weight of the mixture and then
(ii) drying the mixture of step i) to produce the fragrance and/or flavor oil containing particles.
7 . The process for producing the particles according to claim 6 , wherein one or more of the following amounts of constituents (a) through (e) are provided in step i):
(a) 27.5-52 wt % fragrance and/or flavor oil and/or
(b) 2.25-11.25 wt % modified starch and/or
(c) 2.25-11.25 wt % of one or more mono alkaline metal phosphate salts, and/or
(d) 0-6.5 wt % of one or more additional ingredients, and/or
(e) 35-55 wt % of water,
in each case based on the total weight of the mixture.
8 . The process for producing the particles according to claim 6 , wherein the drying step ii) is a spray-drying step.
9 . A particle containing fragrance and/or flavor obtainable by the process according to claim 6 .
10 . A perfumed and/or flavored consumer product comprising one or more particles containing fragrance and/or flavor oil according to claim 1 .
11 . A method of perfuming or flavoring a consumer product by adding one or more particles containing fragrance and/or flavor oil according to claim 1 to the consumer product.
12 . A method for perfuming and/or flavoring a consumer product comprising adding one or more of the particles containing fragrance and/or flavor oil according to claim 1 to a consumer product.
