Embodiment 1
[0430] Example 1 : Preparation of microcapsules A with inner brown coating and outer white coating
[0431] Mannitol (spray-dried mannitol: Pearitol 100SD) was used as the core.
[0432] 120.0 g of ceramide (ceramide PC 104) and 120.0 g of hydrogenated lecithin (lipid S100-3) were added to a mixed solution of 3200.0 g of ethanol, and were completely dissolved at 40°C. 1260.0 g of iron oxide yellow, 252.0 g of iron oxide red, and 45.36 g of iron oxide black were added to the resulting mixture, and sufficiently dispersed using a homogenizer to prepare an internal color coating solution.
[0433] The mannitol of 347.70g is introduced into fluidized bed coating system (Glatt GPOG 1, bottom spray), as crystal seed, then with The inner color coating solution was coated at a feed rate of 0 to obtain particles having a mannitol core coated with an inner color layer.
[0434] Thereafter, 36.0 g of ceramide and 36.0 g of hydrogenated lecithin were added to a mixed solution of 1440....
Embodiment 2
[0437] Example 2 : Preparation of microcapsule B with inner brown coating and outer white coating
[0438] Prepared by fluidized bed process as in figure 1 Color-changing microcapsules with a core and two layers shown in (according to a process similar to Example 1):
[0439] (1) Component: core seed crystal - inner color layer - TiO 2 granular layer
[0440]
[0441] Percentages represent percent by weight relative to the total microcapsule weight.
[0442] II) Composition O / W Emulsion
[0443]
[0444]
[0445] 1. Preparation scheme
[0446] 1. Prepare Phase B in a separate Becher and allow to dissolve at 65°C.
[0447] 2. Prepare phase E separately at room temperature.
[0448] 3. At 80°C, in the main Becher, completely melt phase A and add phase A2.
[0449] 4. Add phase A3.
[0450] 5. Emulsification by gradually introducing phase B into phase A under Rayneri.
[0451] 6. Dilute by introducing phase C.
[0452] 7. Add phase D.
[0453] 8. Cool t...
Embodiment 3
[0458] The O / W emulsion of Example 3 was stable.
[0459] 2, result: the evaluation of described microcapsule stability
[0460] The stability of the microcapsules is characterized by a low ratio of non-ruptured microcapsules (without any friction or pressure applied) in the O / W emulsion body after two months at room temperature, 37°C and 45°C.
[0461] The evaluation is based on 3 parameters:
[0462] - the number of ruptured microcapsules in the body,
[0463] - the level of tinting with yellowing of the white body,
[0464] - After the introduction of the spatula in the body: observation of ruptured microcapsules on the spatula.
