Abstract
Modified starch encapsulated oil particles, and a process for making said particles and products comprising such particles are disclosed. Such particles provide a simple, efficient and effective delivery system that can be used to deliver oils to compositions.
Claims32
An encapsulated oil particle comprising:
- a) a water soluble polymer;
- b) an oil;
- and
- c) a hydrophobically modified silica having a particle size greater than 100 nm;
- wherein the amount of hydrophobic silica is less than or equal to 10% by weight, of said oil.
2 more elements
An encapsulated oil particle comprising:
- a) a water soluble polymer wherein said water soluble polymer is a starch which has been modified by treatment with octenylsuccinic acid anhydride;
- b) an oil;
- and
- c) a hydrophobically modified silica;
- wherein the amount of hydrophobic silica is less than or equal to 10% by weight, of said oil.
2 more elements
An encapsulated oil particle comprising:
- a) a water soluble polymer;
- b) an oil admixture;
- and
- c) a compatible hydrophobic additive admixture,
- wherein said oil admixture and said hydrophobic additive admixture each comprise at least 10% by weight, of an ingredient which is either a hydrocarbon or which comprises a compound having a similar functional unit, said functional unit selected from the group consisting of hydroxyl, aldehyde, nitrile, ester, ketone, ether, sulfate, sulfonate, and mixtures thereof.
