Description

含有微乳膠之固體肥皂組成物    Microemulsion-containing solid soap composition   

本發明係有關於一種固體肥皂組成物、其製造方法及固體肥皂組成物之泡質改良劑。 The present invention relates to a solid soap composition, a method for producing the same, and a foam improving agent for the solid soap composition.

作為臉或身體等之皮膚用洗淨劑組成物等，係廣泛使用以脂肪酸鹽為主成分的固體肥皂組成物。皮膚用洗淨劑組成物，除洗淨力外，更重要的是其使用感優良，從而要求泡質及泡沫持續性(泡沫持久性)良好。舉例而言，當泡沫持續性差，泡沫立即消失時，由於在清洗時無法維持泡沫的彈性，致使用感差，而且無法獲得清洗乾淨的感覺。又，一旦泡沫立即消失，便會因皮膚彼此(手與臉等)的摩擦而對肌膚造成負擔，因此，泡沫持久性愈良好愈佳。就泡質而言，具有彈性及牽絲性之泡沫一般視為品質良好的泡沫；對於固體肥皂組成物，也有人針對泡質的改善進行研究。例如專利文獻1中記載一種洗淨劑組成物，其係包含：脂肪酸肥皂部、及包含具泡質改善效果之水溶性高分子的造粒物。 As a skin cleansing composition for the face, body, etc., a solid soap composition containing a fatty acid salt as a main component is widely used. In addition to the detergency, the skin detergent composition is more important in that it has a good feeling of use, and thus requires good foam quality and foam durability (foam durability). For example, when the foam persistence is poor and the foam disappears immediately, the elasticity of the foam cannot be maintained during washing, resulting in poor use feeling and no clean feeling. In addition, once the foam disappears immediately, it causes a burden on the skin due to the friction between the skin (hand and face, etc.). Therefore, the more durable the foam, the better. As far as foam quality is concerned, foams with elasticity and stretchability are generally regarded as good quality foams; for solid soap compositions, some people have also studied the improvement of foam quality. For example, Patent Document 1 describes a detergent composition comprising a fatty acid soap portion and a granulated product containing a water-soluble polymer having a foaming effect.

微乳膠係呈現透明或半透明的外觀，不會發 生分離而呈穩定，具有可同時摻合水溶性成分與油分之性質。基於此種性質，在化妝品、液狀或凝膠狀之洗淨劑組成物的調製中，係使用微乳膠。專利文獻2中記載一種化妝洗淨劑組成物，其係含有：包含烷基(寡聚)醣苷等的微乳膠、陰離子性界面活性劑及陽離子性聚合物等。 The microemulsion system has a transparent or translucent appearance, is stable without separation, and has the property of being able to mix water-soluble components and oil at the same time. Based on this property, microemulsions are used in the preparation of cosmetic, liquid or gel detergent compositions. Patent Literature 2 describes a cosmetic detergent composition containing a microemulsion containing an alkyl (oligomeric) glycoside or the like, an anionic surfactant, a cationic polymer, and the like.

<比較例1>     <Comparative example 1>    

除在實施例1中未使用微乳膠以外，係藉由同樣方法得到固體肥皂組成物。此比較例1之固體肥皂組成物為由組成物(I)所調製的固體肥皂組成物。 A solid soap composition was obtained in the same manner except that microemulsion was not used in Example 1. The solid soap composition of this Comparative Example 1 is a solid soap composition prepared from the composition (I).

使用實施例1及比較例1中調製的各固體肥皂組成物0.5g作為肥皂試料，以上述方法進行排液時間的評定(試樣中的肥皂試料濃度：0.5g/300mL)。將結果示於表4。排液時間增加率(%)為摻有微乳膠之固體肥皂組成物的排液時間(T1)(秒)相對於比較例1之固體肥皂組成物(未摻有微乳膠之固體肥皂組成物)的排液時間(T0)(秒)的增加率，係依以下計算求得。 0.5 g of each solid soap composition prepared in Example 1 and Comparative Example 1 was used as a soap sample, and the drainage time was evaluated by the method described above (soap sample concentration in the sample: 0.5 g / 300 mL). The results are shown in Table 4. Drainage time increase rate (%) is the drainage time (T1) (seconds) of the solid soap composition with microemulsion compared to the solid soap composition of Comparative Example 1 (solid soap composition without microemulsion) The increase rate of the drainage time (T0) (seconds) is obtained by the following calculation.

排液時間增加率(%)=100×(T1-T0)/T0 Drainage time increase rate (%) = 100 × (T1-T0) / T0

ME摻合量為0%者為比較例1。對固體肥皂組成物摻合微乳膠，則排液時間會增長。尤其是對固體肥皂組成物摻合0.15質量%以上的微乳膠時，則排液時間顯著增長。 Comparative Example 1 was a case where the ME blending amount was 0%. When a microemulsion is blended with a solid soap composition, the drainage time will increase. In particular, when a microemulsion of 0.15% by mass or more is added to the solid soap composition, the drainage time is significantly increased.
