Description

本発明は、泡立ち、泡質、泡切れ、洗い流し後の感触等の使用感が良好で、且つ低温での白濁、おりや沈殿物の発生などが認められない、弱酸性透明洗浄料に関する。   The present invention relates to a weakly acidic transparent cleaning material which has a good feeling of use such as foaming, foam quality, foam breakage, and feel after washing, and is free from cloudiness at low temperature, generation of odors and precipitates.

最近、主として手や身体の洗浄用として、ポンプ式容器や泡吐出型容器等に収納される液状洗浄料が普及してきた。ここで従来、皮膚洗浄料において、脂肪酸石鹸(アルカリ性)が、起泡力および洗浄力等に優れることから多用されている(特許文献1、特許文献2、特許文献3参照)が、これらは一方で、皮膚への刺激性や、洗浄後の肌のつっぱり感といった問題を有している。これは、人の肌が本来弱酸性であるため、これらアルカリ性の石鹸で洗うと、肌のpHが一時的にアルカリ性に傾き、洗浄後肌が弱酸性に戻るまでに一定の時間がかかるため肌に対して負担が大きい事や、洗浄による過度の脱脂によるためである。   Recently, liquid cleaning materials stored in pump-type containers or foam discharge-type containers have been widely used mainly for washing hands and bodies. Heretofore, fatty acid soap (alkaline) has been frequently used in skin cleansing materials because of its excellent foaming power and detergency (see Patent Document 1, Patent Document 2, and Patent Document 3). Therefore, it has problems such as irritation to the skin and a feeling of tightness of the skin after washing. This is because human skin is inherently weakly acidic, so washing with these alkaline soaps will cause the pH of the skin to temporarily become alkaline, and it will take some time for the skin to return to weakly acidic after washing. This is because the load is large and excessive degreasing by washing.

またN−長鎖アシル中性アミノ酸またはその塩は、低刺激性で泡立ち、すすぎ性に優れた洗浄剤として、皮膚洗浄料に広く使用されてきた。(特許文献4、5、6、7)   Further, N-long chain acyl neutral amino acids or salts thereof have been widely used in skin cleansers as a cleansing agent with low irritation, foaming and excellent rinsing properties. (Patent Documents 4, 5, 6, and 7)

さらに、長鎖脂肪酸アミドプロピルベタインを洗浄料に配合する検討も数多くなされている(特許文献8〜12参照)。   Further, many studies have been made on blending long-chain fatty acid amidopropyl betaine into a cleaning material (see Patent Documents 8 to 12).

洗浄料に非イオン性界面活性剤の一種である脂肪酸アルカノールアミド系界面活性剤は洗浄剤に配合することにより起泡力や洗浄力、安定性、感触の良さ、粘度を高める効果を奏することが知られている(特許文献8、特許文献12参照)。   Fatty acid alkanolamide surfactant, which is a kind of nonionic surfactant in detergent, has the effect of increasing foaming power, detergency, stability, good touch and viscosity by blending in detergent. Known (see Patent Document 8 and Patent Document 12).

しかしながら、これらの成分を併用して配合した場合、低温での白濁が認められ、安定性の良好な弱酸性透明洗浄料はこれまで得られていない。したがって、本発明においては、泡立ち、泡質、泡切れ、洗い流し後の感触等の使用感が良好で、且つ低温での白濁、おりや沈殿物の発生が認められない、弱酸性透明洗浄料を提供することを課題とする。   However, when these components are used in combination, white turbidity at a low temperature is observed, and a weakly acidic transparent cleaning material having good stability has not been obtained so far. Therefore, in the present invention, a weakly acidic transparent cleaning material that has good feeling of use such as foaming, foam quality, foam breakage, touch after washing, etc., and no cloudiness at low temperature, no occurrence of odor or precipitate is observed. The issue is to provide.

[安定性(25℃)(5℃)]
調製した洗浄料を25℃若しくは5℃恒温槽にて1ヶ月静置し、状態の確認を目視で行った。評価は、30mLのガラス製マヨネーズ瓶に洗浄料を静かに注ぎ、ガラス越しにフォントMSゴシック、サイズ10の文字が明瞭に見えるかどうか、また沈殿物、おり、白濁が発生していないかどうかを目視で判断し、明瞭に見え沈殿物、おり、白濁が発生していないものを「○」、見えづらい若しくは沈殿物、おり、白濁が発生しているものを「×」とした。
[Stability (25 ° C) (5 ° C)]
The prepared cleaning material was allowed to stand in a thermostatic bath at 25 ° C. or 5 ° C. for 1 month, and the state was visually confirmed. The evaluation was made by gently pouring the cleaning material into a 30 mL glass mayonnaise bottle, and checking whether the font MS Gothic, size 10 characters can be clearly seen through the glass, and whether there is a precipitate, white turbidity. Judgment was made visually, and the precipitates that were clearly visible and had no white turbidity were evaluated as “◯”, and those that were difficult to see or had white turbidity were evaluated as “X”.

表1に示したとおり、実施例1のボディシャンプーは、エタノールを添加することにより、低温での白濁が防止でき、使用感の良好なものであった。また、併用する界面活性剤の量目が範囲外の比較例2〜7においては、使用感に悪影響を及ぼしたり、透明な性状を保つことができなかった。   As shown in Table 1, the body shampoo of Example 1 was able to prevent white turbidity at a low temperature by adding ethanol, and had good usability. Further, in Comparative Examples 2 to 7 in which the amount of the surfactant used in combination was out of the range, the feeling of use was adversely affected and the transparent properties could not be maintained.
