Abstract

PROBLEM TO BE SOLVED: To obtain new baby powder whose all main ingredients are biodegradable organic substances. SOLUTION: This baby powder is obtained by using corn starch which is an organic substance and cellulose powder and/or silk powder which is also an organic substance as main ingredients.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a baby powder characterized in that the main components are all biodegradable organic substances.

[0002]

BACKGROUND OF THE INVENTION Baby powder is usually used after bathing or after changing diapers.
It increases the exhilaration after bathing, and is used to prevent hot flashes, diaper rashes, and crotch gaps. Therefore, the characteristics required for baby powder are smooth skin, excellent moisture absorption, excellent moisture release, excellent adhesion to the skin, and excellent extensibility. And that the powder is less scattered.

[0003] Since the main component of the conventional baby powder is talc (hydrated silicate of magnesium), its mineral particles may block sweat glands and pores of the skin. In addition, baby powders containing water often caused heat and rash. Furthermore, friction between the skin and clothing such as diapers often causes rash and rough skin.

[0004]

The present inventor has made various investigations to obtain a product which overcomes the above-mentioned disadvantages. As a result, unexpectedly, corn starch, which is an organic substance as a main component of the product, and corn starch which is an organic substance By using the material cellulose powder and / or silk powder,
Slippage becomes extremely good, and it has excellent absorption and desorption properties,
By overcoming the above drawbacks, we succeeded in producing safe baby powder. Heretofore, such a baby powder mainly containing only a plurality of organic substances has not been known.

The corn starch used in the baby powder of the present invention may be a commonly used corn starch, but preferably has a chemical name of 2-alkenyl succinic esterified starch, and in particular, octenyl represented by the following chemical formula: Corn starch succinate aluminum (trade name: Octier, manufactured by Nisseki Chemical Co., Ltd.) is preferred.

[0006] Cellulose powder is obtained by pulverizing cellulose. Cellulose powder or powdered cellulose (trade name K)
In addition to C-floc (manufactured by Sanyo Kokusaku Pulp), pulverized crystalline cellulose may be further used.

[0007] Silk powder is obtained by mechanically pulverizing natural silk yarn, and a white powder containing 98% by weight or more of silk is available as a commercial product (trade name: Protein Powder K-SF, K-). UF etc., manufactured by Idemitsu Petrochemical Co., Ltd.). It is desirable that each of the above organic components has as small a water content as possible from the property of the product. As a product, a baby powder composed of the above three kinds of organic substances is preferable.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In the case of the above two kinds of organic substances, the mixing ratio of corn starch is 40 to 60% by weight,
Preferably, it is 45-55% by weight, most preferably 50% by weight, the balance of each being another organic substance. In the case of three kinds of organic substances, corn starch is 40 to 60% by weight, preferably 45 to 60% by weight.
55% by weight, most preferably 50% by weight, and the blending ratio of cellulose powder is 30-50% by weight, preferably 35-45% by weight, most preferably 40% by weight, and silk. The compounding ratio of the powder is 5 to 15% by weight, preferably 7.5 to 12.5.
%, Most preferably 10%. The sum of these ratios is 100% except when other ingredients are blended.
The above two or three kinds of organic substances are used so that

The baby powder of the present invention may contain the following components in appropriate amounts. Powders of talc, kaolin, calcium carbonate, magnesium carbonate, titanium dioxide, magnesium stearate, bentonite, silica and the like, emollients, for example, olive oil, liquid paraffin, squalane, lanolin derivatives, pigments, fungicides,
Fungicides, fragrances and the like can be mentioned.

[0010]

Example 1 A baby powder was prepared by mixing the following components. Octenyl succinic corn starch ester aluminum 50% w / w powdered cellulose 40% w / w silk powder (protein Powder K-SF) 10% w / w

Example 2 The following components were mixed to prepare a baby powder. Octenyl succinic acid corn starch ester aluminum 50% w / w Cellulose powder 50% w / w

Example 3 The following components were mixed to prepare a baby powder. Octenyl succinic acid corn starch ester aluminum 50% w / w Silk powder (protein powder K-SF) 50% w / w

[0013]

According to the present invention, it is possible to obtain a baby powder having good slip, excellent absorption and desorption properties, and low residual properties. It is effective with a very small amount of use. Also,
Even if the baby powder of the present invention enters the bronchi,
It is safe because the main component is a biodegradable organic substance.
