Abstract
The present invention relates to a combination of active agents comprising at least one essential oil, at least one cyclodextrin and at least one liquid fatty substance, the cyclodextrin/essential oil weight ratio ranging from 5 to 12, and to its process of preparation. The present invention also relates to a composition comprising, in a physiologically acceptable medium, such a combination of active agents, and to its process of preparation.
Claims21
Combination of active agents consisting of at least one essential oil, at least one cyclodextrin and at least one liquid fatty substance, wherein:
- the cyclodextrin/essential oil weight ratio ranges from 5 to 12;
- the cyclodextrin is present in said combination in a content ranging from 50% to 80% by weight, with respect to a total weight of the combination;
- the liquid fatty substance is selected from the group consisting of liquid hydrocarbons, liquid fatty alcohols, liquid fatty esters, liquid fatty ethers, silicone oils, and mixtures thereof;
- the liquid fatty substance is present in the combination in a content ranging from 15% to 40% by weight, with respect to the total weight of the combination;
- and
- the essential oil is present in the combination in a content ranging from 0.00001% to 20% by weight, with respect to the total weight of the combination, and
- wherein said combination is in a form of a paste.
Combination of active agents capable of being obtained according to a process consisting of the steps of:
- mixing at least one essential oil with at least one liquid fatty substance, and
- adding at least one cyclodextrin, wherein a cyclodextrin/essential oil weight ratio ranges from 5 to 12,
- then mixing,
- wherein:
- the cyclodextrin is present in said combination in a content ranging from 50% to 80% by weight, with respect to a total weight of the combination;
- the liquid fatty substance is selected from the group consisting of liquid hydrocarbons, liquid fatty alcohols, liquid fatty esters, liquid fatty ethers, silicone oils, and mixtures thereof;
- the liquid fatty substance is present in the combination in a content ranging from 15% to 40% by weight, with respect to the total weight of the combination;
- and
- the essential oil is present in the combination in a content ranging from 0.00001% to 20% by weight, with respect to the total weight of the combination, and
- wherein said combination is in a form of a paste.
