- Table 4 components of bath A The contents of the previous step were left in the bath for 10 to 20 seconds until a capsule (1) was formed. After this time, the capsule (1) was removed from bath A and added to a container with distilled water at a temperature of 20-25 ° (bath B), where it was allowed to act for 1-10 minutes for the reaction to stop and the capsule (1) to get clean of other unwanted components. Once the capsule is obtained, it is stored in a container containing a suitable medium and the process is repeated until the desired number of capsules is achieved.
- the capsules were then stored in a suitable container which contains a suitable stability medium, as mentioned above, under conditions of temperature and humidity that keep them stable until the moment of individual packaging.
- Capsules 3 had the following characteristics:
- Breaking strength 32 gf / cm 2 .
- the capsule can expand its diameter up to 6 mm in diameter (limit up to membrane rupture (2)). Up to 60% of its diameter.
- Example 4 Breakable capsule composition (1) of the first aspect prepared following the method of preparation of the second aspect (reverse esterification)
- Natural Mint Gelled Hand Solution * comprises: Water, Propanediol, Aloe Barbadensis Leaf Juice, Leuconostoc / Radish Root Ferment Filtrate. Benzyl Alcohol, C13-15 Alkano, Decylglucoside, Succinoglycan, Peppermint Oil, Citric Acid, Dehydroacetic Acid, Indigo Dye Leaf Extract, Mica, Tin Oxide, Titanium Oxide.
- Burst pressure measurement can be carried out using a texture analyzer
- a 2 mm cylinder probe was used to determine the rupture and / or compression point of the membrane at the point of contact.
- the capsule is deposited perpendicular to the downward direction of the cylindrical probe which penetrates and breaks the sample at a constant speed.
- the texture analyzer measures the force required to break the capsule.
- the stability of the capsules was determined, for which different resistance tests and aging tests were carried out in the laboratory.
- Stability tests at different temperatures were measured the stability of the capsules of examples 1, 2 and 3 as cosmetic. Duration of the stability test between 12 and 14 weeks.
- the capsules of the first aspect of the invention and those obtained of the second and third aspects were stable to breakage, texture and their application test, especially after 30 weeks at room temperature between 18-25 ° C, preferably 14 weeks and / or after 12 weeks 40 ° C, preferably 8 weeks, and no type of alteration was observed
- the membrane remains stable over time and under forced temperature conditions, it must be able to be undone by applying pressure with the fingers and be able to mix with the core. It is also analyzed:
- a sample is placed in the palm of the hand.
- Time A is between 5 and 25 seconds, preferably below 15 seconds.
- the action can be absorption or adsorption depending on the excipients or active principles of the new phase at least 85% and, preferably, 100%.
- the mixture obtained at the end of section A is applied to the desired area of the skin as an ordinary cosmetic and it is waited until the skin shows the effect desired by the cosmetic. Mainly, it is observed that there are no product residues on the skin and the product is not sticky.
- time B is between 20 and 120 seconds, preferably between 20 and 60 seconds, more preferably between 20-40 seconds.
- time A + B The total time (time A + B) is between 25 to 150, preferably between 25 to 85 seconds, more preferably between 25 to 45 seconds.
