Description

Packaging method for shipping macrocapsules {Packaging method for shipping of macrocapsules}

The present invention relates to a packaging method for preventing damage during transportation of macrocapsules.

Cosmetics are products that are used for the purpose of cleansing or beautifying the human body by means of painting, spraying, and similar methods, and have little effect on the human body, and are largely divided into basic, color, hair, perfume, and men. However, the concept of this traditional cosmetic is continuously changing with the change of the times, and these days, various functional cosmetics or cosmetics with pharmacological effects are being developed.

Recently, the development of cosmetic products encapsulating functional active ingredients in capsules is increasing. Manufacturers selling finished cosmetics often order a capsule filled with a functional active ingredient from an external supplier and use it after being supplied. However, a problem has been raised that the capsule is damaged during the transportation process.

Particularly, in the case of a microcapsule having a small size, the damage rate during transportation is low, but in the case of a macrocapsule having a large size, there is a problem in that the damage rate during transportation is high, and thus a supplementary measure is necessary.

The present invention to prepare a dispersion containing the following thickener 0.01-3.0% by weight, 1,3-butylene glycol 2-10% by weight, glycerin 2-10% by weight, neutralizing agent 0.05-3.0% by weight, and water or oil balance Step (step 1); And

Mixing 2-30% by weight of the dispersion prepared in step 1 and 70-98% by weight of the macrocapsule and putting it in the primary transport container (step 2);

It provides a packaging method for preventing damage during transportation of the macrocapsule containing.

As the thickener, a polymer represented by Chemical Formula 1, a polymer represented by Chemical Formula 2, xanthan gum, cellulose, carboxymethylcellulose (CMC), or the like may be used alone or in combination of two or more. Preferably, as the thickener, a polymer represented by Formula 1 or a polymer represented by Formula 2 may be used, and xanthan gum, cellulose, and / or carboxymethylcellulose (CMC) are additionally mixed depending on the material of the macrocapsule. Can be used.

[Formula 1]

In Chemical Formula 1,

R ¹ is hydrogen or methyl,

R ² is C _10-30 linear or branched alkyl,

x and y are integers of 10-10000.

[Formula 2]

In Chemical Formula 2,

z is an integer of 10-10000.

The packaging method according to the present invention may further include, after step 2, placing the primary transport container in the secondary transport container for shock absorption. A plastic container having a capacity of 5-30 L may be used as the primary transport container, and a styrofoam box or the like may be used as the secondary transport container.

The diameter of the macrocapsules is 150-6000 μm.

In the packaging method according to the present invention, step 1 is 0.01-3.0 wt% thickener, 2-10 wt% 1,3-butylene glycol, 2-10 wt% glycerin, 0.05-3.0 wt% neutralizing agent, and water or This is a step of preparing a dispersion liquid containing the remaining amount of oil.

The dispersion may further include additives such as antifoaming agents, preservatives, surfactants, pH adjusting agents, flavoring agents, and chelating agents.

The thickener plays a key role in reducing the breakage rate of macrocapsules by imparting viscosity in the dispersion.

The thickener used in the present invention may be any commercially available thickener, and preferably, the same thickener as the thickener included in the base used by the cosmetic finished product supplier receiving the macrocapsule may be used. 2-30% (preferably 2-10% by weight) of the base of the same formulation that is commercialized by applying macrocapsules can be used, and when using the base of the same formulation that is commercialized, the supplier receiving the product should take into account the amount used for transportation. Can be commercialized.

Carbopol Ultrez 21, Carbopol Ultrez 20, etc. may be used as an example of the thickener represented by Chemical Formula 1, and Carbopol Ultrez 10, Carbopol 980, Carbomer 941, etc. may be used as an example of the thickener represented by Chemical Formula 2. It is possible to use Carbopol Ultrez 21, Carbopol Ultrez 10 or Carbopol Ultrez 20, more preferably Carbopol Ultrez 21 or Carbopol Ultrez 10, and particularly preferably Carbopol Ultrez 21. The Carbopol Ultrez 21 may have a high thickening effect in a small amount.

The content of the thickener in the dispersion may be 0.01-3.0% by weight, preferably 0.01-0.6% by weight, more preferably 0.01-0.5% by weight, even more preferably 0.01-0.3% by weight. If, when the content of the thickener is less than 0.01% by weight, the viscosity of the dispersion is low, and thus the effect of preventing macrocapsule breakage may be insignificant, and when it exceeds 3.0% by weight, the degree of viscosity improvement according to the increase in content is insignificant, thereby providing economic benefits. none.

The 1,3-butylene glycol serves as a preservative.

The content of 1,3-butylene glycol in the dispersion may be 2-10% by weight, preferably 4-6% by weight. If it is less than 2% by weight, there may be a problem that the antiseptic power is lowered, and if it is more than 10% by weight, there may be a problem that causes skin irritation.

The glycerin serves to flow and moisturize.

The content of glycerin in the dispersion may be 2-10% by weight, preferably 4-6% by weight. If it is less than 2% by weight, there may be a problem of deterioration in flowability and moisture, and if it is more than 10% by weight, there may be a problem in which viscosity decreases.

The neutralizing agent acts as a thickener by reacting with the thickener. Specifically, when a thickener powder single molecule is suspended in water or oil, if a neutralizing agent is added, polymerization and / or crosslinking reaction occurs to increase the viscosity.

Examples of the neutralizing agent may include sodium hydroxide (NaOH), potassium hydroxide (KOH), triethanolamine (TEA), tromethamine, and the like.

In the dispersion, a neutralizing agent may be added to a pH of 5-7.5. If it is outside the pH range of the neutralizing agent, there may be a problem that the thickening effect is lowered.

In the packaging method according to the present invention, the step 2 is a step of mixing 2-30 wt% of the dispersion prepared in step 1 and 70-98 wt% of the macrocapsule and placing it in the primary transport container.

The mixing ratio of the dispersion and the macrocapsule serves as an important factor in reducing the breakage rate of the macrocapsule. In terms of transport cost reduction, preferably, the dispersion may be mixed with 2-5% by weight and macrocapsule 95-98% by weight.

If, when the dispersion is less than 2% by weight, there may be a problem that the macrocapsule breakage rate increases, and if it exceeds 30% by weight, there is no economic advantage because the improvement in the effect of reducing the breakage rate due to the increase in content is negligible.

In addition, the present invention provides a method of transporting a macrocapsule using the macrocapsule packaged by the packaging method.

Hereinafter, the present invention will be described in more detail by the following examples. However, the following examples are only illustrative of the present invention, and the contents of the present invention are not limited by the following examples.
