Description

Cosmetic composition comprising gellan gum

The present invention relates to a cosmetic composition capable of stably suspending a raw material, and relates to a cosmetic composition comprising gellan gum and an additive that promotes a change in the structure of the gellan gum.

Conventional liquid cosmetics containing raw materials, such as petals, use a brow container to smoothly discharge the contents because the raw material sinks to the bottom of the container, but in this case, there is a problem in that it is difficult to apply a pump dispenser.

In order for the raw material in the cosmetic to float stably without sinking by using a general synthetic thickener or gum, a viscosity above a certain level is required like an essence, so there is a problem that the type of cosmetic is limited to a gel.

However, in the case of a water-like cosmetic such as a wiping type skin or cleansing water, it is difficult to suspend the raw material in this type of cosmetic because it is not suitable for a formulation with viscosity because it must be immersed on a cotton pad.

In the case of a liquid cosmetic containing raw material, since the raw material may sink without being suspended for a long time, an additional process such as air pumping is required to float the sunken raw material during filling into individual containers and mix uniformly. However, there is a possibility that the original material may be damaged at this time, which is a problem.

In order to be applied to a liquid type cosmetic, it is not easy to develop a cosmetic that has a low viscosity and can suspend the raw material for a long time.

Under this background, the present inventors have made intensive research efforts to develop a low-viscosity cosmetic composition while stably suspending the raw material. As a result, the cosmetic composition containing gellan gum and an additive that promotes the structural change of gellan gum maintains the low viscosity of the raw material. It was confirmed that it can be suspended for a long time, and the present invention was completed.

An object of the present invention is gellan gum; and

an additive that promotes structural change of the gellan gum, a monovalent metal ion or a divalent metal ion; It is to provide a cosmetic composition that can stably float the raw material, including.

As one aspect for achieving the above object, the present invention is gellan gum; and a monovalent metal ion or a divalent metal ion, which is an additive that promotes the structural change of the gellan gum; It provides a cosmetic composition that can stably float the raw material, including.

Hereinafter, the present invention will be specifically described.

In the present invention, the term "gellan gum" refers to a straight-chain polysaccharide in which glucose, gluconic acid, and rhamnose are regularly repeated, and Pseudomonas elodea isolated from a myelinated plant of the genus Elodea ( Pseudomonas elodea ) Using carbohydrate It is obtained by purifying, drying, and pulverizing the polymer polysaccharide test material obtained by pure culture fermentation.

In the present invention, the gellan gum may have a weight average molecular weight of 200,000 to 300,000 Daltons. The gellan gum may be one in which an acyl group is bound or one in which an acyl group is removed. Gellan gum from which the acyl group has been removed may have higher transparency and thus may be more suitable for use in water-type cosmetics.

The gellan gum may be included in an amount of 0.005 to 0.5 wt%, specifically 0.02 to 0.2 wt%, based on the total weight of the composition. When included in less than 0.005% by weight, the original material cannot be stably suspended for a long time, and the original material may sink over time. may decrease the feeling of use.

In the present invention, the additive may cause a change in the structure of the gellan gum. The additive may be combined with a carboxyl group of the gellan gum to change the gellan gum into an antiparallel double helix structure. When the gellan gum exists alone, it can cause a structural change only when the content is as high as 2% by weight or more, and in this case, it is difficult to maintain a low viscosity due to the high content. On the other hand, when present together with the additive, it exists in a double helix structure.

The additive may be a monovalent metal ion or a divalent metal ion. The monovalent metal ion may be at least one selected from the group consisting of lithium ions, sodium ions, potassium ions, rubidium ions, cesium ions, copper ions, silver ions, and gold ions, but is not limited thereto. The monovalent metal ion may indirectly cause a structural change by offsetting the charge repulsion force between the gellan gums. The divalent metal ion may be one or more selected from the group consisting of a calcium ion, a magnesium ion, a zinc ion, an iron ion, and a copper ion, but is not limited thereto. The divalent metal ion may directly cause a structural change by strongly binding with the carboxy ion of gellan gum. The additive may be adjusted according to the gellan gum content, and in one embodiment, may be included in an amount of 0.04 to 0.08% by weight based on the total weight of the composition.

In the present invention, the composition may be to stably float the raw material. Floating the raw material stably means that the raw material is maintained in a floating state for a long time without sinking to the bottom. The composition may be to suspend the raw material for 2 years or more. Specifically, it may be to float the raw material for 2 years or more and 3 years or less. The raw material may be beads or dried flowers, and specifically, may be rose petals, marigold petals, elderflower, rudbeckia, or spherical agar capsules, but is not limited thereto. The raw material may have a diameter of 500 μm or more, specifically 500 μm or more and 10 cm or less, and more specifically 1000 μm or more and 2 cm or less.

Viscosity was measured under DIR (4rod/6rpm/1min) conditions using RVDV-II+PRO (manufacturer: Brookfield).

In order to check whether the raw material is stably suspended over time, the raw material solution was added and the floating degree of the raw material was observed for 1 to 48 hours, and the floating degree of Comparative Examples 1 to 3 and Examples 1 to 4 was measured. It is shown in FIG. 1 in order from the left.

○: The raw material is stably suspended.

△: The raw material subsides over time.

X: The original material sinks.

From the above results, it was confirmed that the raw material could not be stably suspended for a long time when the gellan gum content was less than 0.02 wt% based on the total weight of the composition, and when the gellan gum content exceeded 0.2 wt%, the viscosity exceeded 1 Pa·s. It was confirmed that it is difficult to use in a liquid form close to viscosityless.

In addition, as a result of measuring the degree of absorption into the cotton pad, as shown in FIG. 2 . When each cosmetic composition according to Examples 1 to 4 and Comparative Examples 1 to 3 was discharged onto the cotton pad, all of them were well absorbed by the cotton pad, and there was no phenomenon in which the contents were deposited and not absorbed into the cotton pad. That is, it was confirmed that the difference in viscosity between the compositions according to Examples 1 to 4 and the compositions according to Comparative Examples 1 to 3 did not have a significant effect when the composition was used for cotton.
