Description

Liquid care composition {Liquid care material}

The present invention relates to a liquid care composition, and more particularly, to a liquid care composition having a novel composition that can be formed into a transparent formulation without causing sediment and floating matter by mixing the main constituents and dissolving smoothly.

In general, the main function of hair care products is to fix the hair in a desired style and tidy up the hair, but in addition to these functions, a temporary coloring effect is given to the hair or the used part shows the effect of emitting light in a dark place. There are also hair care products with new functions added. In such a hair care composition for coloring hair, a colorant or pigment for coloring is often used together with a setting polymer for fixing the style.

At this time, a hair conditioning agent is needed to protect the hair and restore damaged hair.

However, in the conventional hair conditioner composition, protection against damage to hair due to heat during drying or ironing is insufficient.

Therefore, graphene oxide is used together to protect the hair from heat, and a protein that can provide nutrition to the hair is used.

However, when protein and graphene oxide are added together, a precipitate is formed due to agglomeration, or a phenomenon of becoming cloudy without dissolving occurs.

So, the existing products on the market try to solve the problem by adding a very small amount of graphene oxide or a very small amount of protein.

However, active ingredients such as graphene oxide and protein have a problem that the hair care effect is insignificant in a very small amount.

The liquid care composition of the present invention contains an aqueous solution of graphene oxide, protein, polysorbate 80, dipropylene glycol, ethanol, 1,2-hexanediol, and polyglyceryl-4 caprate as main components.

Since graphene oxide has high heat resistance and high strength, hair coated with graphene oxide is expected to have very high heat resistance.

Hair with enhanced heat resistance can alleviate hair damage caused by heat treatment and general ironing.

There are research results that graphene oxide is useful for gloss and surface hardening, and when applied to hair, hard and shiny hair can be expected due to gloss and surface hardening.

In the present invention, graphene oxide 20% aqueous solution is used. The graphene oxide 20% aqueous solution consists of 20% by weight of graphene oxide (60 to 68% by weight of carbon, 30 to 35% by weight of oxygen), and 80% by weight of purified water.

In the present invention, after forming the first mixture and the second mixture, the first mixture and the second mixture are formed to form a liquid care composition. That is, to form a first mixture in which protein, dipropylene glycol, and 1,2-hexanediol were added, and to form a second mixture in which polysorbate 80, Polyglyceryl-4Caprate and ethanol were added to an aqueous solution of graphene oxide Then, the first mixture and the second mixture are mixed to form a liquid care composition. At this time, as an important process in the present invention, after pretreatment of the second mixture, the first mixture and the second mixture are mixed to form a liquid care composition.

The pretreatment process is as follows.

1) Weigh Polysorbate 80 and Polyglyceryl-4Caprate quantitatively and stir at 30~40℃ where fluidity occurs.

2) Ethanol is quantitatively weighed and added to 1).

3) Add 20% Graphene Oxide aqueous solution to 2) and disperse until no precipitate is formed.

The pre-treated second mixture is formed with the first mixture to prepare a liquid care composition.

At this time, the first mixture is formed by mixing 45 to 55% by weight of protein, 35 to 45% by weight of dipropene glycol, and 5 to 15% by weight of 1,2-hexanediol, and the second mixture is Graphene oxide aqueous solution 8 to 12% by weight, polysorbate 80 40 to 45% by weight, Polyglyceryl-4Caprate 3 to 6% by weight, ethanol is formed by mixing 40 to 45% by weight.

In addition, the dipropylene glycol, 1,2-hexanediol, protein, graphene oxide aqueous solution, polysorbate 80, polyglyceryl-4 caprate and ethanol are mixed with purified water to prepare a liquid care composition.

At this time, the purified water 75.0-98.0 wt%, the dipropylene glycol 0.05-7.00 wt%, the 1,2-nucleic acid diol 0.1-4.0 wt%, the protein 0.5-7.0 wt%, the graphene oxide aqueous solution 0.003 to 0.40% by weight, 0.2 to 2.5% by weight of the polysorbate 80, 0.03 to 1.7% by weight of the polyglyceryl-4 caprate, and 0.2 to 2.5% by weight of the ethanol are mixed to finally make a liquid care composition.

Since the liquid care composition of the present invention prepared in this way is mainly used for hair treatment, the present invention can be called a liquid hair care composition.

In the present invention, the protein is composed of a hydrolyzed protein, and the protein is composed of Laurdimonium Hydroxypropyl Hydrolyzed Wheat Protein, Hydrolyzed Sweet Almond Protein, Hydrolyzed Wheat Protein, Hydrolyzed Soy Protein, and the like. The protein may be composed of any one selected from Laurdimonium Hydroxypropyl Hydrolyzed Wheat Protein, Hydrolyzed Sweet Almond Protein, Hydrolyzed Wheat Protein, and Hydrolyzed Soy Protein.

In the present invention, purified water 75.0-98.0 wt%, dipropylene glycol 0.05-7.00 wt%, 1,2-nucleic acid diol 0.1-4.0 wt%, protein 0.5-7.0 wt%, graphene oxide aqueous solution 0.003-0.40 wt% , polysorbate 80 0.2 to 2.5 wt%, polyglyceryl-4 caprate 0.03 to 1.7 wt%, and ethanol 0.2 to 2.5 wt% to make a liquid care composition, and the functions of each component are as follows.

If the purified water is less than 75.0% by weight, the viscosity of the liquid care composition may occur and there may be difficulties in hair treatment. Since the effect may be reduced, the content of purified water is adjusted within the above range.

The protein provides conditioning to the hair, gives vitality, facilitates hair care, and forms a film on the hair surface to help prevent static electricity. If the protein is less than 0.5% by weight, the antistatic efficiency is lowered and it is insufficient to give hair conditioning.

In addition, the polysorbate 80 is composed of a nonionic surfactant, and dipropylene glycol can be replaced with polyols having a hydroxyl group. Polysorbate 80 is a surfactant-emulsifier, surfactant-solubilizer, etc., which helps to stabilize the emulsion of other ingredients that do not mix with each other and easily dissolves poorly soluble ingredients. If the polysorbate 80 is less than 0.2% by weight, it cannot play a functional role of easily dissolving the poorly soluble components, and when the polysorbate 80 exceeds 2.5% by weight, the procedure is inconvenient due to the sticky feeling of use.

The dipropene glycol functions as a hair moisturizer. If the dipropylene glycol is less than 0.05 wt%, it cannot function as a hair moisturizer, and if the dipropylene glycol exceeds 7.00 wt%, the sticky texture remains excessively on the hair and the quality of the hair is deteriorated.

If the aqueous solution of graphene oxide is less than 0.003% by weight, there is almost no heat protection function and hair may be damaged from heat. If the aqueous solution of graphene oxide exceeds 0.40% by weight, it is not dissolved in the formulation and aggregates with proteins The liquid care composition deteriorates and becomes difficult to use.

The ethanol is used as a solvent. Ethanol is mixed as a solvent in which the other components are easily mixed. If the ethanol content is less than 0.2% by weight, mixing of the other components may not be performed smoothly, and if the ethanol content exceeds 2.5% by weight, the quality of odor, texture, and touch may deteriorate due to volatility of ethanol, which may cause inconvenience to consumers.

The 1,2-hexanediol serves as a moisturizer and prevents the growth of bacteria when mixed with water. If the 1,2-hexanediol is less than 0.1% by weight, the hair moisturizing effect does not come out and the proliferation of bacteria is not properly prevented, and when the 1,2-hexanediol exceeds 4.0% by weight, it gives excessive moisture to the hair, 1,2-hexanediol is adjusted to 4.0 wt% or less.

The polyglyceryl-4 caprate is a material that helps the dissolution of other components as a surfactant. Polyglyceryl-4 caprate, together with polysorbate 80 and ethanol, helps to dissolve graphene oxide and prevents aggregation. If the amount of polyglyceryl-4 caprate is less than 0.03% by weight, there is no effect in preventing dissolution and agglomeration. Therefore, it is also important to adjust the content of the polyglyceryl-4 caprate in the range of 0.03 to 1.7 wt%.

Hereinafter, protein, graphene oxide mixing test is shown. The content unit of each component in Tables 1 to 10 is weight %.
