Description

W/S type cosmetic composition containing a mixture of a high content lactate metal salt and silicone oil {W/S Type Cosmetic Composition Containing High-Content Potassium Lactate and Silicon Oil}

The present invention relates to a W/S type cosmetic composition comprising a mixture of a high content lactate metal salt and a silicone oil, and more specifically, a lactate metal salt derived from a lactate metal salt by including a silicone oil together with a high content lactate metal salt. It relates to a W/S type cosmetic composition that significantly improves the feeling of use by deodorizing irritating odors and unpleasant odors, and exhibits an effect of improving the condition of the skin by enhancing skin moisturizing power and decreasing skin irritation.

Typically, the types of emulsified cosmetic compositions are largely divided into oil in water (O/W) emulsification type, water in oil (W/O) emulsification type, and water in silicone (W/S) emulsification type. It is roughly different.

The oil-in-water (O/W) emulsification type is a hydrophilic type and has a moist and soft feeling of use, but has a disadvantage in that the persistence of makeup and water resistance are poor. In order to improve these disadvantages, a lipophilic water-in-oil (W/O) emulsification type was developed. However, the water-in-oil (W/O) emulsifying type has excellent makeup persistence and water resistance, but has a disadvantage in that it puts a burden on the skin due to stickiness, oily, waxy, etc., and the feeling of use such as spreadability and spreadability is poor. In particular, conventional emulsion compositions contain a large amount of hydrocarbon oils such as squalane, ester oils such as C12-C15 alkylbenzoate, vegetable oils such as olive oil and macadamia nut oil, and these oils are known to have skin irritation. It is not satisfying the consumer's desire for hypoallergenic cosmetics.

Water in silicone (W/S) emulsification type is an emulsified formulation with silicone oil enveloping water and has a silky texture that improves skin texture and protects the skin.

In addition, silicone oil is very light due to its elastic and three-dimensional structure, and has excellent feeling of use and skin stability such as spreadability, as well as excellent water resistance and emollient effect.Therefore, efforts to use it in cosmetics have been continued. Development of a water-in-silicone (W/S) emulsion-type cosmetic composition using silicone oil as an external wound has been continuously made.

Lactate metal salts, such as potassium lactate, are widely used in cosmetic formulations as emulsifiers, pH adjusters, preservatives, coloring agents, skin softeners and exfoliating agents.In particular, potassium lactate is safe to the skin and penetrates the skin. It has been used in many functional cosmetic formulations as a substance that has an effect, promotes the moisture retention and moisture retention ability of the stratum corneum, and promotes penetration of other moisturizing ingredients applied to the skin (Patent Document 1, Non-Patent Document) 1). However, when lactate metal salt is included in a formulated cosmetic product in a particularly high content, it changes into an unstable formulation over time, and there is a problem in that the feeling of use decreases due to the occurrence of an irritating odor.

Looking at the prior art related to the method for reducing irritation odor by the active ingredient contained in the composition and the method for reducing skin irritation, the acid-basic property suitable for deodorizing the irritating odor derived from the acetate-based compound in the composition. A chemical neutralization method is known to reduce the irritating odor caused by the acetate-based compound by chemically neutralizing the acetate-based compound by mixing a component such as a lactate metal salt (see Patent Document 2), and a metal ion in the composition, such as potassium ions, etc. Although the literature revealing the effect of reducing skin irritation has been disclosed (see Patent Document 3), a method of deodorizing irritating odors caused by a high content of lactate metal salts in cosmetics intended for skin moisturization and reducing skin irritation. No information has been disclosed.

Accordingly, there is a need for a means capable of deodorizing the irritating odor of a cosmetic composition containing a high content of lactate metal salt having an excellent skin moisturizing improvement effect and reducing the skin irritation sensation.

The degree of irritating odor of each of the compositions of Examples 1 to 8 and Comparative Examples 1 to 8 prepared in Preparation Example 1 was measured with an Odor meter (OMX-GR, Shinyei, Japan).

Specifically, each composition was measured three times in an Odor meter for 60 seconds at the same content (0.1 g) to obtain an average value (the higher the measured value (a.u.) of the Odor meter means that the irritating odor/odor is severe).

As a result, as shown in Table 5 and FIG. 1, it was confirmed that the composition of Example 8 has the effect of remarkably deodorizing irritating odors than the composition of Comparative Example 1 or the composition of Comparative Example 2.

Specifically, it was confirmed that the composition of Example 8 had about 2.7 times higher deodorant effect than the composition of Comparative Example 1, and about 1.4 times higher deodorant effect than the composition of Comparative Example 2.

In addition, it was confirmed that the compositions of Examples 1 to 7 had a deodorizing effect equivalent to that of the composition of Example 8, and the compositions of Comparative Examples 3 to 7 were confirmed to have a deodorizing effect equivalent to that of the composition of Comparative Example 2.

The composition of each of Examples 1 to 8 and Comparative Examples 1 to 8 prepared in Preparation Example 1 was applied to a group of 20 subjects to check the degree of skin irritation.

Specifically, each subject first took a rest for about 15 minutes after cleansing, and then applied the composition of each of Examples 1 to 8 and Comparative Examples 1 to 8 in an appropriate amount (e.g., 0.5 g) to both cheeks and around the eyes, and then about 10 After waiting for a minute, the degree of skin irritation, that is, the degree of skin irritation, burning, itching, and aching in the eyes/eye area, was scored by listening to the opinions of each subject on a total of 6 points on a scale of 6 points, and then scored by 20 subjects. The result was calculated as an average value to evaluate skin irritation. Here, if the score of each item is high, it means that the degree of skin irritation, burning, itchiness, and eye/eye sensation is high, and skin irritation was evaluated according to the evaluation criteria in Table 6 below.
