Description

Capsule essence and method for manufacturing capsule essence

Technical Field

The present invention relates to a capsule essence, which can be particularly used as a skin care, and a method for manufacturing the same.

Background

The essence is a skin care product with high concentration and strong effect, and has good effects of anti-aging, anti-wrinkle, moisturizing, whitening, freckle removing and the like because the essence contains active ingredients, trace elements, collagen, serum and the like with high concentration.

As shown in fig. 1, the essence is usually contained in an ampoule 7 made of glass or hard plastic, such as MARTI DERM skin-moistening essence and MARTI DERM skin-caring essence, which are widely known. In use, as shown in fig. 2, the head 71 of the ampoule 7 needs to be broken off, and then the essence inside the ampoule 7 is poured out or sucked out.

However, in the process of breaking off the head 71 of the ampoule 7, the breaking point is often sharp, so that the hand of the user may be accidentally contacted with the breaking point to cause the hand of the user to be cut off.

Disclosure of Invention

1. The invention aims to provide a capsule essence which has the advantages that a user can take out the essence conveniently in the essence using process, and hands are not easy to be injured.

The technical purpose of the invention is realized by the following technical scheme: a capsule essence comprises a double-layer capsule, wherein the diameter of the double-layer capsule is between 2.2mm and 4mm, and the double-layer capsule comprises an active ingredient layer, an efficacy ingredient layer and a gel shell;

the active ingredient layer contains active ingredients for nourishing skin, the functional ingredient layer is wrapped outside the active ingredient layer, the functional ingredient layer contains functional ingredients for skin care, auxiliary ingredients for matching the functional ingredients and at least one liquid polyelectrolyte, and the gel shell is wrapped outside the functional ingredient layer and used for protecting the functional ingredient layer and the active ingredient layer;

wherein, the stability of active ingredients (such as Ganoderma lucidum fermented extract and yeast essence in plant fermented extract) is poor, partial chemical substances are easy to be oxidized, and partial chemical substances are easy to be photolyzed; the stability of functional components (such as butanediol, propylene glycol and various derivatives of alcohol substances and the like of moisturizers) is relatively good, but partial chemical substances in the functional components are easy to oxidize;

when not used, the gel shell can encapsulate the active ingredients and the functional ingredients, so that the gel shell is prevented from being directly contacted with air and being oxidized by the air to further lose efficacy; meanwhile, the functional components and the active components are separated from each other, so that the functional component and the active components are effectively prevented from reacting due to mutual contact to further influence the efficacy of the active components. In use, the user can break the gel shell of the double-layer capsule to allow the active ingredients, the functional ingredients and the auxiliary ingredients to flow out, mix them together uniformly by hand, and then apply the mixture on the skin surface. Therefore, each component can ensure the maximum activity when in use, and meanwhile, the ampoule is convenient, safe and reliable, and the problem that the hand of a user is scratched by the head fracture of the ampoule as the user needs to break the ampoule can be effectively avoided.

In all of these applications, the gel shell of the bi-layer capsule is typically made of a material that is biocompatible with the human body. For this purpose, a biocompatible, biodegradable and in most cases non-toxic polymer (e.g. a polysaccharide) can be used to form the shell. Advantageously, the polymer is capable of changing from a liquid state in solution to a state of particular viscosity, so as to form a gel that ensures mechanical retention of the liquid contained in the bilayer capsule. In the gel state, the individual chains of the polyelectrolyte, together with the multivalent ions, form a tight three-dimensional network that retains the liquid core and prevents it from flowing. The individual chains are held to each other and are not free to flow to each other. In this state, the viscosity of the formed gel was infinite. In addition, the gel has a broad value for flow stress. The stress threshold is greater than 0.08 Pa. The gel also has an elastic modulus that is non-zero and greater than 50 kPa.

The active ingredient layer comprises at least one surfactant before contacting with the functional ingredient layer, the surfactant accounts for 0.06-0.28% of the active ingredient by weight, and the gel shell is prepared by reacting liquid polyelectrolyte with a gelling solution.
