Abstract

The present invention relates to a method for manufacturing a bath additive that has buoyancy using pores and exhibits fluidity in water, and more specifically, to a method for manufacturing a bath additive, 1. A primary mixing process (S100) for producing a primary mixture by mixing soda and purified water in a ratio of 100:1 to 100:10 to facilitate dispersion; and 2. A dough manufacturing process (S200) in which a primary mixture produced by a primary mixing process is mixed with starch and a surfactant to facilitate residual dispersion; 3. Since the above starch absorbs purified water, the reaction between the surfactant and the purified water is suppressed compared to when all raw materials are mixed at once, and when the dough is made as above, a secondary mixing process (S300) of mixing citric acid into the dough; The above-mentioned soda, purified water, starch, surfactant, and citric acid are not mixed together, but are processed step by step, so that the soda, purified water, and citric acid react to generate carbon dioxide and disappear. Accordingly, in order to perform the secondary mixing process (S300), a molding process (S400) is performed using a mold to form a certain shape within a certain time, preferably within 90 to 120 minutes, from the time citric acid is mixed into the dough.

Description

Method for manufacturing a bath additive having buoyancy using pores and expressing fluidity in water The present invention relates to a method for manufacturing a bath additive that possesses buoyancy using pores and exhibits self-fluidity in water. More specifically, it relates to a bath additive that possesses buoyancy using pores and exhibits self-fluidity in water, wherein when water is added to a bathtub after it has been filled with water, the water and the bath additive react, causing the bath additive to move its position due to the reaction gas and create bubbles on its own. Bath additives refer to products that smooth the skin and relax muscle tension during the bathing process, while also providing functions such as moisturizing, exfoliating, and alleviating skin conditions. They exist in various formulations, primarily including bubble baths, bath oils, bath balls, and bath powders, and are manufactured appropriately considering ease of use and product functionality. Among these, solid bath balls and bath powders are primarily used to improve skin texture, moisturize, and relieve muscle tension. The raw materials constituting these products can vary widely, but salt, sodium bicarbonate, citric acid, and tartaric acid are commonly used, while natural extract powders and natural oils are additionally used to impart specific functions. For example, Korean Patent Publication No. 2004-21306 discloses a vitamin C bath product composed of a mixture of 10-40% by weight of vitamin C, 40-60% by weight of a solidifying agent, 5-10% by weight of a dissolving agent, 5-10% by weight of a mixing agent, 2-5% by weight of a foaming agent, and 1-3% by weight of other additives, which are then solidified and purified. In addition, Korean registered patent No. 0969323 discloses a skin cleanser with excellent water solubility characterized by being solidified by mixing 34 to 39 weight% sodium bicarbonate, 31 to 35 weight% ascorbic acid, 17 to 21 weight% citric acid, 8 to 12 weight% solidifying agent, and the remainder being other additives. Examining the characteristics of these bath additive ingredients reveals that they utilize materials that are either solid or liquid without moisture. This is intended to minimize the degradation of their functionality caused by contact with atmospheric moisture. This is especially true for products made by mixing acidic components (such as citric acid and tartaric acid) with alkaline components (such as sodium bicarbonate), including bath bombs and bath balls. If we examine the composition of bath bombs or bath balls in more detail, they utilize acids, bases, skin-protecting ingredients, and fragrances. When placed in a bathtub filled with water, the reaction between the acid and base generates carbon dioxide, providing visual entertainment through the bubbles. While this product offers visual appeal compared to others, it has a fatal weakness in that the acid and base are exposed to the atmosphere due to its formulation. In other words, as the acid and base react with moisture in the atmosphere in the same phase, microbubbles are continuously generated, and when the above formulation is immersed in water, the bubble-generating ability decreases significantly over time. To prevent this phenomenon, packaging that minimizes contact with moisture in the air is used, but it cannot be prevented 100%. In particular, when stored in high-humidity conditions or in places with relatively high humidity, such as bathrooms, moisture may condense between the packaging and the contents, and this is even more critical if holes (so-called breathing holes) are made in the packaging material to minimize packaging volume. In addition, it is extremely difficult to add skin moisturizing ingredients to the above-mentioned type of bath product due to its formulation composition. Generally, polyol ingredients such as glycerin and butylene glycol, which are moisturizing ingredients used in cosmetics, cannot be used. Accordingly, most moisturizing effects are achieved by using essential oils or polymers, but due to the characteristics of the formulation, it is difficult to add an excessive amount sufficient to feel the actual moisturizing effect. If an excessive amount is added, it becomes difficult or impossible to mold the formulation, and the user experience becomes extremely poor, such as the formulation becoming soft or failing to spread in the bath. Accordingly, many consumers and cosmetic developers are suggesting the need to develop cosmetic formulations that can stably maintain their form to ensure comfortable use, while simultaneously sustaining the formulation's performance for an extended period and providing additional high moisturizing effects.
