Description

TECHNICAL FIELD The present invention relates to a composition containing a natural vinegar and a raspberry extract as an effective ingredient, a process for producing the composition, and a method for stabilizing the composition. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composition, }

Disclosed herein is a method for preparing a composition containing natural vinegar and plant extract as an active ingredient, and a stabilizing method thereof.

The condition of hair and scalp is easily affected by internal and external environment. For example, hair and scalp health deteriorate due to internal factors such as ultraviolet rays, hot and dry wind, repetitive use of a dye or hair styling agent, external factors such as indoor heating and unusual combing, stress, nutritional deficiency, .

In order to improve the health of the scalp, vinegar has been traditionally used to dilute vinegar to rinse or wind the hair, but the vinegar has an acidic environment in the scalp and hair, There was a limit due to the fragrance.

In recent years, various methods have been used to improve the state of deteriorated hair and scalp, such as taking nutrients, physical treatment such as scalp massage, and use of hair products such as hair conditioners. Hair and scalp management methods using hair products which are relatively low in cost and have immediate effect are mainly used. However, the current hair conditioner contains synthetic components such as paraffin and silicone as main components. The synthetic components are accumulated in the hair and the scalp without being washed away, causing a primary trouble such as inflammation on the scalp, Dandruff, or keratinization.

Therefore, in recent years, needs for hair products using natural raw materials have been rapidly increasing. Products currently on the market have problems such as discoloration, rust, rancidity, microbial growth and the like, which are inherent limitations of natural raw materials, The hair conditioner containing the substance as a main component has a limit in which the effect is significantly lowered.

Hereinafter, the present invention will be described in detail.

In one aspect, the present invention relates to a process for producing an incremental tablet, which comprises admixing purified water, polyols, a thickener and a phenolic acid to form an incremental tablet; A step of preparing a vinegar part by mixing alcohol and vinegar; By weight based on the total weight of the composition, 60 to 80% by weight of the incremental part, 8 to 15% by weight of the vinegar part, 3 to 10% by weight of the surfactant and 1 to 10% , A method for stabilizing a composition for hair or scalp.

Stabilization of a composition herein may mean minimizing deterioration of the composition, separation of formulations, and the like, such as discoloration, breaking or the production of foreign matter. Thus, stabilization of the composition may include one or more of discoloration inhibition or improvement, suppression or improvement of discoloration of the composition, and inhibition or improvement of the formation of foreign substances in the composition.

In one embodiment, the method may be carried out according to the following sequence: 1) a mixture of a thickener and a surfactant; 2) mixing the blended phloem and surfactant with vinegar; 3) Mixing the above-mentioned mixture of the gradual part, the surfactant and the vinegar part with the plant extract.

The method is optimized for the stabilization of the composition, and when it is carried out in the order of 1) - > 2) - > 3), a stabilizing effect of the composition can be obtained. For example, 1) → 3) → 2), 2) → 3) → 1, 2) → 1) → 3), 3) → 2) → 1) 1) - > 2), etc., problems of deterioration of the composition and / or separation of formulations occur.

In one aspect, the plant extract may comprise from 1 to 10% by weight, based on the total weight of the composition. The plant extract may be contained in an amount of preferably 1 to 8% by weight, more preferably 3 to 8% by weight, based on the total weight of the composition. If the content of the plant extract is less than 1% by weight, the effect of improving the scalp can not be expected. If the content of the plant extract is more than 10% by weight, excessive fragrance may give a feeling of rejection during use.

In this respect, the increment can be 60 to 80% by weight, preferably 65 to 80% by weight, more preferably 72 to 78% by weight based on the total weight of the composition. The polyol contained in the gradual section may be contained in an amount of 3 to 10% by weight, preferably 3 to 7% by weight, based on the total weight of the composition. When the amount of the polyol is smaller than the above range, the surfactant can not be solubilized and the separation of the formulation and the transparency of the formulation can be lowered. If the amount exceeds the above range, irritation of the scalp can be caused.

In addition, the thickener included in the incremental portion may be included in an amount of 0.01 to 0.5% by weight, preferably 0.05 to 0.2% by weight, based on the total weight of the composition. If it is contained in an amount of less than 0.01% by weight, the formulation stability is deteriorated, and if it exceeds 0.5% by weight, the viscosity of the composition becomes too high.

In the above aspect, the amount of the phenolic acid contained in the gradual section may be 0.01 to 0.5% by weight, and preferably 0.05 to 0.2% by weight based on the total weight of the composition. If it is contained in an amount exceeding 0.5% by weight, the pH of the composition is excessively lowered, and there is a limit to acidify the scalp and hair. If the amount of the phenolic acid is less than 0.01% by weight, the growth of microorganisms in the composition can not be inhibited, and foreign matter in the formulation can be produced.

Particularly, the vinegar is preferably natural vinegar, and when the natural vinegar is included in the above amount, the cuticle on the hair, the exfoliation of the scalp and the proper pH maintenance effect of the scalp are excellent. In particular, if the content of vinegar exceeds 5% by weight, the pH of the composition may be excessively lowered, which may deteriorate the health of the scalp, and the solubilization of the formulation may not be effected effectively, resulting in suspension and precipitation of the formulation. When the natural vinegar is contained in an amount of less than 1% by weight, the effect of adjusting the cuticle and / or keratin of the composition is deteriorated and the hair condition improving effect can not be expected.

In addition, the surfactant may be included in an amount of 3 to 10% by weight based on the total weight of the composition. The surfactant is preferably contained in an amount of 3 to 9% by weight. When the surfactant is contained in an amount of 10% by weight or more, the transparency of the composition is lowered and irritation to the scalp may occur.

The composition may also comprise from 0.05 to 2.0% by weight of polyquaternium, based on the total weight of the composition. The polyquaternium may preferably be contained in an amount of 0.05 to 1.5% by weight, more preferably 0.05 to 0.5% by weight. If the polyquaternium is included in an amount exceeding 2.0% by weight, excessive viscosity may occur in the formulation and precipitation and separation phenomena may occur in the formulation. If the polyquaternium is contained in an amount of less than 0.05% by weight, the formulation stability may be deteriorated.

In one embodiment, the polyquaternium can be preferably polyquaternium-10.

If either of the polyol, salicylic acid and polyquaternium is absent, the stability of the formulation may become unstable, such as discoloration of the composition, discoloration, or formation of foreign matter. Furthermore, even if some of the above components are included in the composition or even if some of them are out of the content range of the respective components, discoloration, detachment and / or foreign matter may be generated, and the stability of the composition may be deteriorated.

In one embodiment, the incremental step comprises mixing at 70-90 < 0 > C. The step of increasing the temperature may preferably be carried out at 75 to 85 캜, more preferably 77 to 83 캜. If the mixing temperature is higher than 90 ° C in the manufacturing step of the gradual section, deformation of the raw material may occur due to heat, resulting in discoloration and detachment. If the mixing temperature is lower than 70 ° C, the raw materials are not dissolved and precipitation or precipitation And microbial growth problems may occur in the formulation.

In the above-described aspect, the step (1) may be followed by mixing the thickener and the surfactant, and then cooling the mixed thickener and the surfactant to 50 to 60 ° C, followed by mixing the vinegar.
