Abstract

The invention relates to a method for obtaining the water-insoluble fraction of Carica papaya sap, enriched with Carica papaya lipase, the water-insoluble fraction obtainable by this method, a method for the preparation of an activated fat and/or an activated wax by means of said water-insoluble fraction of the Carica papaya sap, the activated fat and/or the activated wax capable of being obtained by this method, a composition combining said activated fat and/or said activated wax, as well as the cosmetic use of these products.

First claim

The invention claimed is:

1. A method for obtaining a water-insoluble fraction of Carica papaya sap, enriched with Carica papaya lipase, the method comprising the following steps:
a) suspending dried Carica papaya sap in distilled water in a weight ratio of dried raw Carica papaya /distilled water of between 0.01 and 0.5, between 0.05 and 0.25, between 0.08 and 0.2, or 0.1,
b) centrifuging the suspension obtained in step a) for a time period of between 5 minutes and 90 minutes, between 15 minutes and 60 minutes, or between 20 and 40 minutes, and at a rotation speed of between 2000 and 6000 rpm, between 3000 and 5000 rpm, or at 4000 rpm to obtain a pellet containing the water-insoluble fraction of the Carica papaya sap, enriched with Carica papaya lipase,
c) recovering the pellet containing the water-insoluble fraction of the Carica papaya sap, enriched with Carica papaya lipase,
and the method further comprising, after step a) and before step b), the following step:
a′) stirring the suspension obtained in step a) for a time period of between 15 minutes and 240 minutes, a time period of between 30 minutes and 180 minutes, between 60 minutes and 150 minutes, or 120 minutes at room temperature.

2. The method according to claim 1 , the method further comprising, after step b) and before step c), the following step:
b′) drying the pellet until a particulate powder is obtained;
wherein the water-insoluble fraction of Carica papaya sap, enriched with Carica papaya lipase, is recovered in step c), in the form of particulate powder.
