Description

Water-soluble cosmatic composition for Non-preservative system

The present invention relates to external preparation compositions such as non-aqueous cosmetics, and in particular, to external preparations such as various non-aqueous cosmetics having antiseptic power, low skin irritation, and excellent usability and antiseptic stability.

External preparations, such as non-aqueous cosmetics, cannot be avoided by microorganisms during manufacture, by skin contact with the finger or the like during use, by the surface of the skin, or by exposure to outside air during use. For this reason, chemical preservatives, such as parabens, are mix | blended with cosmetic compositions for the purpose of suppressing microbial proliferation, and killing these microorganisms with preservation with time, and improving the shelf life of a product. Of course, it is also possible to manufacture non-aqueous cosmetic compositions without chemical preservatives, but in this case, to secure antiseptic power, it is necessary to use sterile preparation, limit the amount or period of use, use a container which is divided into small portions, or a container that cannot be refilled. It may lack economic versatility.

The present inventors have made the following inventions as a result of studying a non-aqueous cosmetic composition capable of securing antiseptic power without compounding a chemical preservative.

The present invention solved the preservation problem of non-aqueous cosmetic by containing 0.1 to 50% by weight of caprylic / capric glyceride, 0.01 to 10% by weight of alpha-bisabolol, 0.1 to 60.0% by weight of coconut oil.

The present invention provides a non-aqueous oil-soluble antiseptic cosmetic composition having excellent antiseptic properties without using conventional chemical preservatives.

The present invention solved the preservation problem of non-aqueous cosmetic by containing 0.1 to 50% by weight of caprylic / capric glyceride, 0.01 to 10% by weight of alpha-bisabolol, 0.1 to 60.0% by weight of coconut oil. The present invention is illustrated by the following examples. However, these examples do not limit the present invention.

(Example)

(Examples 1 to 6 and Comparative Examples 1 to 6)

  To prepare a lipstick (including lip gloss) with the components and component ratios (% by weight) shown in Table 1 and to perform the antiseptic (challenge) experiment as follows.

Sample Preparation

① Put 50g (50ml) of sample into 50ml conical tube.

② It is good to test 10 kinds of bacteria including contaminants individually, but you can test by group. In the former case, as many as the number of inoculation bacteria, in the latter case, seven tubes may be prepared. (In this case, the required sample amount is 350g)

Group 1: E.coli, S.aureus, P.aeruginosa

Group 2: B.subtilis, B.cereus

Group 3: C.albicans

Group 4: A.niger, Penicillium

Experiment by preparing 4 tubes for each sample.

200ml sample should be prepared.

Challenge

① Dilute Bacteria in sterile saline solution to make 10 ⁸ cells / ml and yeast and mold to 10 ⁷ cells / ml.

- Group 1: E.coli, S.aureus, P.aeruginosa is overnight incubation in 1: 1: 1 mix inoculated with 0.5ml / 50g samples being the original protocol in this case final concentration of about 10 ⁷ cells / ml It is about 5 to 10 times higher than the concentration listed, but you do not need to dilute it.

Group 2: B. subtilis and B. cereus are spore forming bacteria that do not significantly decrease throughout the experiment. Inoculation volume is added in 0.4 ~ 0.45ml / 50g sample (slightly less than Group 1).

-Group 3: C. albican has a final concentration of 10 ⁵ cells / 50g when 0.5ml / 50g of overnight culture solution is added.

-Group 4: Cell # should be measured by counting directly with hemocytometer. 10 ml of saline is added to the culture medium for 1-2 weeks, and the surface is gently scraped to harvest spores, and then diluted 1/10 to 1/100 to cell counting. (A.niger should be diluted 1/10 to 1/100 and Penicilliu should be at least 1/100 in order to be countable. Inoculate each final concentration to 5 * 10E5.

② Inoculate 0.5ml of diluted bacteria into each tube and mix evenly. (The final concentration in the sample is 10 ⁶ cells / ml for bacteria and 10 ⁵ cells / ml for yeast and mold.)

③ Samples inoculated with mold and yeast should be kept at 25 ~ 30 ℃ and bacteria inoculated with 30 ~ 35 ℃.

④ After 0, 1 ~ 2 days, 7 days, 14 days, 21 days, 28 days after inoculation, take a part of the sample (0.1ml or 0.1g), spread it on the prepared plate and incubate in the incubator.

⑤ Take out the plate after 2 days and measure the number of bacteria.

Judgment

① Measure the number of germs on each plate and display as follows.

     +++: 100 CFU / plate or more

     ++: 10 ~ 99 CFU / plate

     +: 1 ~ 9 CFU / plate

     -: 0 CFU / plate

② Judgment pass or fail is determined according to the following criteria.

Preservation condition Bacteria Reduced to less than 0.1% of initial inoculation by Day 7
(Less than 100 cfu / plate) and subsequent decay thereafter Sphere forming
bacteria The number of inoculation bacteria remains stagnant or declining. Yeast, mold Reduced to less than 10% of initial inoculation by Day 7
(1000 cfu / plate) and thereafter a steady decrease

In addition, to measure the feeling of use, the test method of the feeling was judged by the expert of cosmetics by the maintenance of the formulation as a cosmetic and a comprehensive measurement of the feeling through the test was simply determined as good or bad.
