Description

[Technical Field]

[0001] The present invention relates to compositions having a pearlescent appearance. [Background technology]

[0002] When incorporating higher fatty acids into liquid skin care cosmetics, emulsification with an emulsifier or solubilization with a surfactant is essential, and the appearance of the liquid skin care cosmetics has been limited to a white emulsion or a transparent solution. On the other hand, there are also topical skin preparations that have a pearly appearance with an uneven appearance, such as an example using fatty acid glycol esters (Patent Document 1). However, fatty acid glycol esters are components used in cleansing cosmetics such as shampoos and body soaps, and have the drawback of not being able to be incorporated into skin care cosmetics.

[0112] <Test Example 1> Evaluation test of pearly luster composition (1) Preparation of pearly luster composition The components shown in Tables 1 to 5 were mixed at 70 to 80°C. The mixture was then stirred for 10 minutes while maintaining the temperature at 70 to 80°C. Next, the mixture was stirred while being cooled to 25 to 35°C, thereby preparing pearly luster compositions of Examples and Comparative Examples.

[0113] In this case, Polyquaternium-51 was used as a comparative example as a substitute for polyvinylpyrrolidone (PVP). In addition, xanthan gum was used as a substitute for quince seed extract and / or cellulose derivatives in comparative examples. In addition, as a nonionic surfactant with an HLB value of less than 10, PEG-20 hydrogenated castor oil isostearate (HLB value: 8) was used.

[0114] (2) Evaluation of pearly luster compositions (2-1) Stability evaluation The pearly luster composition obtained in (1) was stored at 5 to 40°C for one month, and the stability after one month was visually evaluated. The evaluation criteria are shown below. The results are shown in Tables 1 to 5. 5: Same as before storage. Appearance, gloss, and usability are all good. 4: Slight settling and loss of gloss are observed, but it can be used without any problems. 3: Slight settling or separation is observed, but recovery is achieved by manual stirring several times, so it is acceptable for the product. 2: Obvious settling or separation is observed, and the product is not acceptable as it cannot be completely recovered even after manual stirring. 1: Severe separation and aggregation occur, and manual stirring does not restore the product, making it unusable.

[0115] (2-2) Sensory evaluation (usage sensation) A panel of five cosmetic experts used the pearly luster compositions of each Example and Comparative Example after washing their faces, and evaluated the ease of application and non-stickiness on a 5-point scale (1: bad to 5: good).

By comparing Examples 1, 8 to 11 with Comparative Examples 4 and 5, it was found that the use of polyvinylpyrrolidone (PVP) resulted in excellent compatibility and non-stickiness when applied, as well as excellent stability. By comparing the pearly luster compositions of Examples 1 and 12 to 19, which used quince seed extract, hydroxyethyl cellulose (cellulose derivative), and hydroxypropyl methyl cellulose (cellulose derivative) as quince seed extract and / or cellulose derivatives, with Comparative Example 1, which did not contain quince seed extract or cellulose derivatives, it was found that the use of quince seed extract and / or cellulose derivatives resulted in excellent compatibility and non-stickiness when applied, as well as excellent stability. By comparing the pearly luster compositions of Examples 1 and 12 to 19, which used quince seed extract, hydroxyethyl cellulose (cellulose derivative), and hydroxypropyl methyl cellulose (cellulose derivative) as quince seed extract and / or cellulose derivatives, with Comparative Example 2, which used xanthan gum as a substitute for quince seed extract and / or cellulose derivatives, it was found that the use of quince seed extract and / or cellulose derivatives resulted in excellent compatibility and non-stickiness when applied, as well as excellent stability. By comparing the pearly luster compositions of Examples 1 and 20 to 23, which used PCA glycereth-25 isostearate (HLB value: 14), PCA PEG-40 hydrogenated castor oil isostearate (HLB value: 11), and PEG-60 glyceryl isostearate (HLB value: 16) as nonionic surfactants with an HLB value of 10 or more, with Comparative Example 3, which used PEG-20 hydrogenated castor oil isostearate (HLB value: 8) as a nonionic surfactant with an HLB value of less than 10, it was found that the compositions had excellent compatibility and non-stickiness when applied, as well as excellent stability.
