Embodiment 1
[0232] Example 1: Formulation Example
[0233] The following formulations were prepared (inv fla represents the inventive formulation and compa fla represents the comparative formulation):
[0234]
[0235] Notice:
[0236] Comparative formulation 2 does not contain the claimed esters of dextrins and fatty acids;
[0237] Comparative Formulation 3 does not contain the claimed ester-terminated poly(ester-amide);
[0238] Comparative Formulation 4 does not contain the claimed hydrophobic silica.
[0239] Follow the steps below to prepare the recipes listed above:
[0240] Mix oil phase A with a magnetic bar and heat to 80°C until it becomes a homogeneous phase, then cool to 60°C, then add water phase immediately (add fragrance just before adding water phase B + C + D + E + F and pearls);
[0241] Phase B was prepared at 25°C and dispersed homogeneously using VMI RAYNERI manufactured by TURBOTEST, then heated above 80°C and mixed with a disperser until the matrix became c...

[0247] Example 2: Evaluation Example
[0248] The formulation prepared in Example 1 was evaluated for stability and robustness.
[0249] Using a Binder oven (USA) by leaving the invention and comparative formulations in the oven for 2 months at 40 o C. 45 o C and 65 o The stability test of the inventive formula and the comparative formula was carried out at C for 2 months.
[0250] Using a Zhongke Meiling refrigerator (YC-260L, China) by leaving the invention and comparative formulations in the refrigerator for 2 months at 4 o C (stability) Stability testing was performed for 2 months.
[0251] Light stability testing was performed for 24 hours using ATLAC (AMETEK Measurement and Calibration Technologies).
[0252] Freeze-thaw stability testing was performed for 10 cycles using a Binder oven (USA). In each cycle, the temperature will change from 20 in 24 hours o C gradually changes to -20 o C.
[0253] Finally, a robustness test was performed with the L.A.B. equipment...

Abstract
A composition in the form of an oil-in-water emulsion is provided, comprising: a) a dispersed fatty phase comprising: at least one hydrocarbon-based polar oil, at least one ester-terminated poly(ester-amide), at least one Esters of dextrins with fatty acids, pigments in the form of porous or non-porous, spherical or non-spherical inorganic or organic white particles having a refractive index greater than or equal to 1.6 and a volume size less than 30 μm, and b) a continuous aqueous phase, It contains: at least one hydrophilic gelling agent, hydrophobic silica.
Description
technical field [0001] The present invention relates to the field of cosmetics, and in particular to the field of compositions in the form of visible droplets suspended in a liquid. Background technique [0002] There are currently two-phase compositions on the market that appeal to consumers due to their aesthetic properties. These compositions consist of two mutually immiscible phases which are temporarily mixed together by shaking prior to use. [0003] Pickering emulsions are of great interest to consumers and are widely used in cosmetic products due to their aesthetic and surfactant-free properties. To form Pickering emulsions, finely divided solid particles are adsorbed at the interface between the oil and the homogeneous mixture and serve to stabilize the oil droplets. [0004] However, these emulsions have a tendency to become unstable over time on storage. The reason for this is the observed deposition or even phase separation of solid particles, resulting in an ...
