A method of preparing acerola extract powder coated with a silicone oil mixture, and a whitening cosmetic composition containing acerola extract powder prepared by the method {A Cosmetic composition containing Acerola extract powder coated with silicone oil mixture}

The present invention comprises a whitening cosmetic composition comprising an acerola extract powder containing natural vitamin C coated with silicone oil, a method for producing a natural acerola extract powder coated with a silicone oil mixture and acerola extract powder prepared by the method It relates to a whitening cosmetic composition.

The beauty of the East and the West is very different. The beauty of the West sees the sunburned brown skin as the beauty, while the beauty of the East sees the bright skin as the beauty. Is popular.

Human skin undergoes various biological reactions to maintain homeostasis to the external environment. The skin is the largest organ covering the outer surface of a person. Human skin is composed of epidermis, dermis and subcutaneous tissue. The epidermis is composed of stratum corneum, granule layer, pore layer and basal layer. have. Subcutaneous tissue is composed of blood vessels and fats that act as a cushion.

Human skin color is determined by the amount of melanin, carotene and hemoglobin, of which melanin is the most decisive factor, melanin is produced in the melanocytes in the basal layer of the skin, and the skin is turned over Through this process, although it varies from person to person, it represents the skin color of a person from the basal layer (living cell) to the stratum corneum (dying cell). When abnormally low melanin is produced, skin lesions such as vitiligo are caused. On the contrary, when excessively produced, melanin is known to form spots and blemishes, and melanin moves to the stratum corneum to protect against ultraviolet rays.

Melanin is a type of amino acid tyrosine that is produced through several biochemical processes due to the action of tyrosinase. Tyrosinase is more activated by ultraviolet rays, so the skin turns black when exposed to a lot of sun. High levels of melanin appear dark in skin, and low levels of melanin appear light in skin

Raw materials with various whitening effects competitively inhibit the action of tyrosinase, inhibit melanin production by inhibiting the biochemical process leading to melanin, or make the existing melanin thin. Most of the cosmetics for the skin whitening effect are made of substances that inhibit tyrosinase activity. For example, plant extracts such as vitamin C, vitamin C derivatives, lettuce extract, green tea extract, and aloe extract, kojic acid, arbutin, and useful licorice. Extracts.

Vitamin C (L-Ascorbic Acid) is a water-soluble vitamin, effective against superoxide radical anion, hydrogen peroxide, the hydoxylradical and singlet oxygen, and vitamin E and Vitamin C work together to protect cells from oxidative damage. (African Journal of Biotechnology Vol. 8 (19), pp. 5053-5058, 5 October, 2009; Physiol. 126: 217-224. Farombi EO, Olowg BI, Emerole GO (2000).), in vivo (skin, blood, other Tissues) are important antioxidants (such as Colin Dellery, Therapeutic drugs A213pp ~ A215pp, Churchill Livingstone, 1999) and prevent cardiovascular disease when ingested (Duk- Hee Lee et al., Am J Clin Nutr 2004; 80: 1194-200) also have the ability to remove peroxides and harmful oxygen from metabolism (Bendich A et al., Advanced in Free Radical Biology and Medicine, 2: 419-444, 1986) also involved in melanin synthesis in the skin It inhibits the activity of tyrosinase and reduces the oxidized melanin formed by the oxidation process and converts it into reduced melanin, which has the effect of improving pigmentation such as freckles caused by melanin. (Postaire E et al., Biochem Mol Int, 42: 1023-1033, 1997)

Vitamin C (L-Ascorbic Acid) has difficulty in formulation due to instability against heat, light, moisture, oxygen, etc., and most of vitamin C derivatives are less effective than vitamin C. There is a disadvantage that can be exerted only by cutting the function, and side effects such as skin irritation may occur as the solvent used to prepare the derivative remains. In addition, plant extracts are not sustained in effect, and tyrosinase activity inhibitory power is insignificant. Kojic acid and oil-soluble licorice extracts have excellent whitening effects, but have low product stability and limited usage and whitening effects.

Therefore, the development of a stable whitening cosmetic composition containing natural vitamin C is urgently required.

Acerola cherry is a fruit produced in Brazil's Malphigia shrub. More precise scientific name is Malphigia emarginata and Malphigia glabra. It contains about 17% of natural vitamin C. Vitamin C is water-soluble, so it can't penetrate fat-soluble skin, which is why it is coated with silicone oil. It is also believed to be of greater value as vitamin C derived from non-synthetic plants.

The use of acerola extract in cosmetics uses acerola cherry fermented substance as a fermentation material using bacteria by extracting and filtering acerola into puree in Korean Patent No. 1998-086770, which uses organic acid without vitamin C at all. As acerola extract was used acerola extract containing 17% natural vitamin C. Acerolari contains vitamin C and the extraction and commercialization of vitamin C is described in us patent 3,012,941 and us patent 3,086,915.

Various methods have been attempted to infiltrate vitamin C into the skin. Among them, Korean Patent Application No. 1998-57379 uses cyclodextrin, which is open at both ends, and has some disadvantages of vitamin C being leaked. In Korean Patent No. 2001-11602, a method of stabilizing vitamin C using silicon was developed. However, when the addition of natural oils having a large amount of emulsifier, the emulsion state is destroyed and layer separation occurs. In US Pat. No. 58,434,11, the present invention proposes a cosmetic composition by dissolving vitamin C in a silicone solution and then adding a thickener.

In addition, in the present invention, 10-20% by weight of polyoxyethylene 60 hydrogenate castor oil is dissolved at 50-60 ° C., rather than only coated with silicon oil, in order to effectively coat the acerola extract using silicon oil. After dissolving completely by adding 20 wt%, 60 to 80 wt% of silicone oil is mixed to prepare a silicone mixture, which is then mixed with acerola extract powder and more preferably coated.

The reason for adding polyoxyethylene 60 hydrogenate castor oil (HCO-60) is that HCO-60 is a hydrophilic surfactant ( J.chin.chem. Soc., Vol. 35, NO.6.1988 ) . Silicone oil) wraps the functional material of water-soluble (acelora extract).

In addition, HCO-60 is incorporated into the oil phase (silicone oil) and increases skin absorption.

( YAKUGAKUZASSHI128 (4) 611-616 (2008)) itself has a function of better stabilizing surfactants, and a mixed layer of silicon and HCO-60 is formed between silicon and acerola extracts than coating with silicon alone. Stable.

Anhydrous ethanol dissolves HCO-60. Since HCO-60 and anhydrous ethanol are added to the oil phase (silicone oil), ethanol anhydride is 99.9% instead of 95% (ethyl alcohol 95%, water 5%). (99% or more of ethyl alcohol, 1% or less of water) is preferably used.
