Embodiment 1

[0040] Phase components parts by volume Mass proportion (%) Phase A water 45.95 glycerin 5 Propylene Glycol 4 Sodium hyaluronate 0.05 Phase B Polydimethylsiloxane 30 Vitamin C 10 Cyclopentasiloxane 5

[0041] Preparation:

[0042] Mix phase S1 and phase A, heat to dissolve to a transparent liquid, cool to room temperature, and wait for filling;

[0043] S2. Weigh the components of phase B in turn, mix them evenly, homogenize at a high speed, promote the uniform dispersion of VC powder, and wait for filling;

[0044] S3, filling phases A and B to such as figure 1 in different compartments inside the bottle as shown. If necessary, when filling phase B, the filling equipment is equipped with a stirring device to ensure the uniform dispersion of VC powder.

[0045] Qualified through inspection, is the cosmetic of embodiment 1.

Embodiment 2

[0047] Listed in the table below is the composition of Example 2. For the phase A part of the water preparation in Example 2, in order to ensure that different functional components do not affect each other, phase A is divided into two component phases, A1 and A2.

[0048] Phase components parts by volume Mass proportion (%) Phase A1 water 26.75 A2 phase Ethoxydiglycol 5 Propylene Glycol 4 Sodium hyaluronate 0.05 Trehalose 1 xanthan gum 0.2 Phase B1 Polydimethylsiloxane 30 Vitamin C 20 Phase B2 Cyclopentasiloxane 5 white mineral oil 5 Glyceryl caprylate 3

[0049] Preparation:

[0050] Mix phase S1 and phase A, heat to dissolve to a transparent liquid, cool to room temperature, and wait for filling;

[0051] S2 and phase B are weighed in turn, mixed evenly, and homogenized at a high speed to promote the uniform dispersion of VC powder; to be filled...

Abstract

The invention relates to multi-phase cosmetics capable of solving the problem of a big possibility of inactivation of ascorbic acid and derivatives thereof, and a technical scheme of the multi-phase cosmetics. The cosmetics consist of a phase A (water aqua) and a phase B (an oil agent and powder). The B phase consisting of the oil agent and dry powder mainly comprising one or more of VC and a derivative thereof can effectively solve the problems of a high inactivation speed, color change and the like of VC in the water aqua; and the composition form of the phase B is convenient to mix parts of the phase B and parts of the phase A during use to form cosmetics use liquid, the remaining phase A and the remaining phase B are still in a separated state and do not influence each other, and the problem that ascorbic acid products are unstable during storage is solved. During use, only parts of the mixture need to be pumped out, other parts of the phase A and the phase B are still independently stored and do not interfere with each other so as to guarantee that each drop is freshly mixed during use, user experience is improved, since the activity of the VC is 100% sealed, the skin care function of the VC is fully played, a skin care effect is guaranteed, and very high practicability and wide applicability are achieved.

Description

technical field [0001] The invention relates to a cosmetic for solving the easy inactivation of ascorbic acid, in particular to a multiphase cosmetic for solving the easy inactivation of ascorbic acid and its derivatives and its technical proposal. Background technique [0002] Ascorbic acid, namely vitamin c (VC for short) is a water-soluble vitamin, which has excellent anti-oxidation, whitening, anti-wrinkle, anti-aging, promotion of skin collagen regeneration and many other beauty and skin care functions. [0003] However, because vitamin C is too unstable, especially in aqueous solution, it quickly decomposes and becomes inactivated and discolored. It poses great challenges to product stability and skin care experience. [0004] At present, all commercially available products have this problem. Some products add polyhydric alcohols such as propylene glycol and butylene glycol together with vitamin E and other antioxidant ingredients to slow down the oxidation rate of vi...
