JP6676353B2 - Bath additive - Google Patents

Description

  The present invention relates to bath additives. More specifically, the present invention relates to a bath agent that sufficiently retains fragrance and has stable quality.

  There are various bathing agents used in hot water in a bath tub for the purpose of promoting blood circulation and a warm bath effect, or for easily enjoying a hot spring feeling even at home. In addition, the relaxing effect and the feeling of use are enhanced by the fragrance compounded in the bath agent.

  It is a feature that the proportion of the fragrance compounded in the bath agent is larger than that of products such as cosmetics so that the user can feel the scent even in the bath water. The proportion of a general fragrance is, for example, about 0 to 0.1% by weight in the case of a lotion, whereas it is blended in the range of 0 to 3% in a bath salt.

  In addition, there are bath agents which attempt to diffuse the fragrance into the bath water promptly to improve the fragrance, and for example, a bath agent described in Patent Document 1 has been proposed.

  However, a phenomenon occurs in which the fragrance leaks out over time, except when a tightly sealed container is used in the bath agent. As a result, the incense tone at the time of use is remarkably reduced as compared with the time of initial filling, and the quality of the product may be impaired.

  Further, the fragrance component generally has a small molecular weight, and depending on the material of the container, the fragrance may leak through the packaging material. There is also a problem that the scent that has leaked from the bathing agent is transferred to another adjacent formulation. Further, there is a problem that the fragrance component dissolves and deforms the component of the container.

  On the other hand, when a strictly sealed container is used, there is a problem that the inside becomes negative pressure and the container is deformed due to a change in atmospheric pressure.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a bath agent that sufficiently retains aroma and has stable quality.

  In order to achieve the above object, the bath additive of the present invention is composed of a mixed composition containing at least a perfume containing a monoterpene, β-cyclodextrin, and a silicate compound.

  Here, the perfume is easily adsorbed and retained by the β-cyclodextrin and the silicate compound.

  In addition, when the monoterpene is limonene, dissolution or deformation of the container components due to limonene can be suppressed. For example, when the container is made of polystyrene, it may be dissolved with limonene, but by holding this in the mixed composition, the dissolution does not occur.

  When the silicate compound is calcium silicate, the fragrance is more easily adsorbed and retained.

  In addition, when the content of β-cyclodextrin is 1 to 5% by weight based on the total amount of the bath agent, it becomes easier to more sufficiently adsorb and retain the fragrance.

  On the other hand, when the content of β-cyclodextrin is less than 1% by weight based on the total amount, the adsorption of the fragrance becomes insufficient, and the fragrance leaks. If the content of β-cyclodextrin exceeds 5% by weight based on the total amount, the powder fluidity of the preparation becomes high, and powdering occurs at the time of filling, which makes handling inconvenient.

  In addition, when the mixed composition is contained in a container made of a material containing polystyrene, it is difficult for the monoterpene to dissolve or deform the container.

  In order to achieve the above object, the bath additive of the present invention is composed of a mixed composition containing an inorganic salt, a fragrance containing at least monoterpene, β-cyclodextrin, and calcium silicate. I have.

  Here, the β-cyclodextrin and calcium silicate make it easy to adsorb and hold the fragrance.

  Hereinafter, the composition of an example of a bath agent to which the present invention is applied will be described.

  The weight ratio of the bath additive shown here is sodium hydrogencarbonate: 93.5%, β-cyclodextrin: 5.0%, flavor (citrus): 1.0%, calcium silicate: 0. It has a composition containing 5%.

  Sodium bicarbonate is a main component of the bath additive, emulsifies skin stains, and has a cleaning effect. In the above composition, 93.5% is blended.

  β-cyclodextrin is a base that retains fragrance, and is incorporated at 5.0% in the above composition.

  The fragrance (citrus) perfumes the bath additive and contains limonene. In the above composition, 1.0% is blended.

  Calcium silicate adjusts the powder fluidity of the bath additive and also acts as a moisture absorbent for absorbing moisture. In the above composition, 0.5% is blended.

  Here, the main component of the bath agent is not limited to sodium bicarbonate. For example, inorganic salts such as sodium sulfate, magnesium sulfate, sodium carbonate, sodium sesquicarbonate, calcium carbonate, sodium chloride, potassium chloride, amino acids and sugars, and alum may be used. The dosage form is not limited, and may be powder, granules, or crystals.

  Further, the weight ratio based on the total amount of β-cyclodextrin does not need to be limited to 5.0%. However, β-cyclodextrin is preferably blended in a weight ratio of 1.0 to 5.0% by weight based on the total amount, from the viewpoint of sufficiently adsorbing the fragrance and retaining the fragrance.

  Further, the weight ratio based on the total amount of calcium silicate is not necessarily limited to 0.5%.

  An example of the bath agent to which the present invention described above is applied has a composition that sufficiently retains the scent and hardly causes scent leakage and scent transfer. Further, the filled container is hardly deformed.

  As described above, the bath preparation to which the present invention is applied has a sufficient scent and a stable quality.
