Description

本発明は、泡立ちが優れ、濃密な泡質にも拘らず、ツッパリ感や刺激を抑え、ザラの発生や保存安定性の悪化を抑えた表面状態が改善された固形洗浄剤組成物に関し、特に機械練り固形石鹸製品に関する。     The present invention relates to a solid detergent composition having an improved surface state that is excellent in foaming and suppresses a feeling of irritation and irritation, and suppresses generation of roughness and deterioration of storage stability, despite the dense foam quality. It relates to machine-kneaded bar products.

近年、泡質の改善を目的に脂肪酸塩のアルキル鎖を特定した固形洗浄剤組成物の検討がなされている(特許文献1)。
しかしアルキル鎖長を長くすることで濃密でクリーミィーな泡質に改善できるが、皮膚への残留も高くなり、すすぎ時のきしみや刺激性が高くなる。そこで、両性活性剤(特許文献2)やポリマー(特許文献3)を配合し改善を訴求している。
特に特定のポリマーを配合する事で高い改善効果が見出されているが、ザラの発生や品質安定性の悪化のため他の配合成分が大きく制約されている(特許文献4、特許文献5)。
In recent years, a solid detergent composition in which an alkyl chain of a fatty acid salt is specified has been studied for the purpose of improving foam quality (Patent Document 1).
However, by increasing the alkyl chain length, it can be improved to a dense and creamy foam, but also increases the residue on the skin and increases the squeaking and irritation during rinsing. Therefore, an amphoteric active agent (Patent Document 2) and a polymer (Patent Document 3) are blended to promote improvement.
In particular, a high improvement effect has been found by blending a specific polymer, but other blending components are greatly restricted due to the occurrence of roughness and deterioration of quality stability (Patent Documents 4 and 5). .

At this time, it is preferable to use an amphoteric surfactant obtained by subjecting a monohalocarboxylic acid to a condensation reaction with an amine compound and then subjecting the reaction mixture to a reverse osmosis membrane treatment, followed by desalting and concentration.
The polymer compound is a cationic polymer selected from polyquaternium-6, polyquaternium-7, polyquaternium-22, polyquaternium-39, polyquaternium-44, polyquaternium-47, polyquaternium-52, polyquaternium-68, and polyquaternium-94, and an amphoteric high polymer. It is preferably a molecule.
More preferably, the polymer compound is one or more polymers selected from homopolymers, dipolymers, and terpolymers derived from the specific cationized monomer represented by the general formula (1). .

更に固形洗浄剤組成物が機械練り固形洗浄剤組成物であることが好ましい。
The polymer compound is preferably polyquaternium-39 or polyquaternium-7.

泡立ちが優れ、濃密な泡質にも拘らず、ツッパリ感や刺激を抑え、ザラの発生や保存安定性の悪化を抑えた固形洗浄剤組成物を提供する。 Disclosed is a solid detergent composition which has excellent foaming and suppresses a feeling of irritation and irritation in spite of dense foam quality, and suppresses the occurrence of roughness and deterioration of storage stability.

本発明固形洗浄剤組成物の洗浄成分の主体はA成分である特定の疎水基長を持つ脂肪酸塩である。本発明固形洗浄剤組成物は、アシル基構成平均炭素数が13.5〜15.5となる様に調整されたアシル基構成炭素数8〜22の脂肪酸塩を65〜97重量%含む。
アシル基構成平均炭素数は、例えばミリスチン酸(アシル基炭素数14)50重量%、パルミチン酸(アシル基炭素数16)50重量%で構成された混合脂肪酸塩の場合14×50%+16×50%=15となる。
The main component of the cleaning component of the solid detergent composition of the present invention is a fatty acid salt having a specific hydrophobic group length which is the A component. The solid detergent composition of the present invention contains 65 to 97% by weight of a fatty acid salt having an acyl group constituent carbon number of 8 to 22 adjusted so that the acyl group constituent average carbon number is 13.5 to 15.5.
The acyl group constituting average carbon number is, for example, 14 × 50% + 16 × 50 in the case of a mixed fatty acid salt composed of 50% by weight of myristic acid (acyl group carbon number 14) and 50% by weight of palmitic acid (acyl group carbon number 16). % = 15.

A成分を構成する脂肪酸塩のアシル基構成平均炭素数が13未満だと泡質が悪くなり、16を超えると泡立ちが悪くなる。さらにアシル基構成平均炭素数は13.5〜14.5が、最も泡立ちが良くなり濃密な泡となるため好ましい。
また、塩に関してはナトリウムやカリウムのような無機塩、トリエタノールアミン、塩基性アミノ酸のような有機塩が挙げられる。
When the acyl group constituent average carbon number of the fatty acid salt constituting the component A is less than 13, the foam quality is deteriorated, and when it exceeds 16, the foaming is deteriorated. Further, the acyl group-constituting average carbon number of 13.5 to 14.5 is preferable because foaming is best and dense foams are obtained.
In addition, regarding salts, inorganic salts such as sodium and potassium, and organic salts such as triethanolamine and basic amino acids can be mentioned.

A成分の特定の疎水基長を持つ脂肪酸塩の配合量が本発明固形洗浄剤組成物に対して65重量%未満となると泡立ちが悪くなり、97重量%を超えると固形洗浄剤組成物の保存安定性が悪化する等の問題が発生するため好ましくない。
本発明のB成分である両性活性剤は、市場流通しているものを幅広く採用できる。しかしながら通常の両性界面活性剤は、アミン類を4級化することにより合成されるが、4級化剤にモノハロカルボン酸、例えばモノクロル酢酸等使用した場合、塩素イオンを含有する無機塩が副成する。両性界面活性剤30重量%水溶液中に5〜10%程度の反応副産物として無機塩を含有する場合がある。
When the blending amount of the fatty acid salt having a specific hydrophobic group length of the component A is less than 65% by weight with respect to the solid detergent composition of the present invention, foaming deteriorates, and when it exceeds 97% by weight, the solid detergent composition is stored. This is not preferable because problems such as deterioration of stability occur.
As the amphoteric activator which is the B component of the present invention, a wide variety of commercially available products can be used. However, ordinary amphoteric surfactants are synthesized by quaternizing amines. However, when a monohalocarboxylic acid such as monochloroacetic acid is used as the quaternizing agent, an inorganic salt containing chloride ions is added as a secondary salt. To do. In some cases, an inorganic salt is contained as a reaction by-product of about 5 to 10% in a 30% by weight aqueous solution of an amphoteric surfactant.

後述する本発明の(D)要件である固形洗浄剤組成物中の無機塩含量が0.1重量%以下に制限する条件を両性界面活性剤の配合と同時にクリアするため、両性界面活性剤水溶液を逆浸透膜処理及びまたは電気透析処理して両性界面活性剤水溶液に副生物として含有する無機塩を両性界面活性剤30重量%水溶液に対して1重量%未満に減塩した脱塩処理両性界面活性剤を使用することが望ましい。 In order to clear the condition that the inorganic salt content in the solid detergent composition, which is the requirement (D) of the present invention described later, is limited to 0.1% by weight or less simultaneously with the amphoteric surfactant blending, an amphoteric surfactant aqueous solution A desalting treatment amphoteric interface in which an inorganic salt contained as a by-product in an amphoteric surfactant aqueous solution is reduced to less than 1 wt% with respect to a 30 wt% aqueous amphoteric surfactant solution by reverse osmosis membrane treatment and / or electrodialysis treatment It is desirable to use an activator.

本発明のB成分である両性活性剤は純分で固形洗浄剤組成物に対して0.5〜3.0重量%の配合が望ましい。0.5重量%未満だとツッパリ感の抑制効果が弱くなり、好適例の3重量%を超え5%を超えると固形洗浄剤組成物の軟化が起こり、保存安定性が悪化するため好ましくない。
本発明のB成分である両性活性剤の好適例としては、(B1)〜(B4)で示されるアミド結合を含有する両性界面活性剤を用いることが好ましい。
The amphoteric activator which is the component B of the present invention is preferably mixed in a pure amount of 0.5 to 3.0% by weight based on the solid detergent composition.

前記表1の結果より、特定の脱塩を行った両性活性剤と特定の両性ポリマーを共に配合する事により石鹸のざらつきを抑え、使用後のツッパリ感の無い、本願の効果が得られていることが分かる。 From the results shown in Table 1, the effect of the present application is obtained, in which the roughness of soap is suppressed by blending the amphoteric activator having been subjected to specific desalting and the specific amphoteric polymer together, and there is no feeling of crispness after use. I understand that.

以下、本発明のその他の配合例について説明する。いずれの配合例も常法により製造した。
なお、いずれも使用後につっぱり感を残さず、且つ泡質もクリーミィーで石鹸のざらつきが改善されたものであった。
Hereinafter, other blending examples of the present invention will be described. All the formulation examples were produced by a conventional method.
In all cases, there was no feeling of tension after use, the foam quality was creamy, and the roughness of the soap was improved.
