Description

Anti-oxidation whitening cream containing tea polyphenol

Technical Field

The invention relates to the technical field of face cream, and particularly relates to an antioxidant whitening face cream containing tea polyphenol.

Background

The cream is a cream or liquid milky white substance which is smeared on the face, and can play the roles of skin care, water replenishing, whitening and the like after the face is cleaned. Is an important step before makeup. The cream is an oily protective film covering the skin, which can effectively retain water and nutrients. And can effectively block some harmful substances in the air, repair fine wrinkles gradually formed on the skin, activate the regeneration capability of cells and enhance the resistance of the skin. The face cream is divided into day cream and night cream, wherein the day cream is used in the day, mainly aims at the skin problems encountered in the day and generally has the sun-screening capacity, and the night cream is mainly used at night and mainly has the functions of moisturizing and repairing.

In normal circumstances, the cream is used in the last step of basic skin care, which is cleansing, toner, lotion, cream, although some of the previous steps may be omitted in combination with the skin itself. The dosage of the face cream is probably one soybean, if the dosage is too much, the skin can not absorb the cream, pores can be blocked, the cream is pushed away from the middle to two sides from the forehead area during smearing, a circle-drawing massage method is adopted, and a pressing action is properly added, so that the acupuncture points are stimulated by the pressing action, and the friction is reduced. The water locking property of the skin-care product is much better than that of other skin-care products, and the skin can achieve the effect of long-acting moisture retention.

Many substances for caring skin are often added into the cream to make the cream have specific effects, for example, substances for diminishing inflammation and removing acne such as bletilla striata, ampelopsis japonica, rhizoma typhonii, aloe, lithospermum, semen cuscutae, chinaroot greenbrier rhizome and radix angelicae are added to make acne-removing cream; adding Ginseng radix and Ganoderma to make anti-wrinkle cream; the whitening substances such as lemon, angelica dahurica and the like are added to prepare the whitening cream, and the cream has the basic moisturizing effect. When the face cream in the prior art is used, the face cream is directly smeared on the face and absorbed by massage, and then the face cream forms a water retention layer on the surface layer of the face, so that the face is moist and glossy. However, nutrient substances in the cream can be oxidized when directly contacting with air, the loss of effective components is caused by serious oxidation, the cream is usually stored for a period of time after the production is finished, and the color of the cream is usually changed. The discoloration of the cream is mainly due to oxidation. In addition, the maintenance endurance of the face cream is weak, the good effect of the common face cream is only good in a period of time just after the face cream is applied, the maintenance effect of the face cream applied to the face is weakened along with the passage of time, and the skin can not be maintained for a long time. The face cream in the prior art is easy to deteriorate and has poor whitening effect.

Disclosure of Invention

In view of the above, the invention provides an antioxidant whitening cream containing tea polyphenol, which has the characteristics of difficult deterioration, long storage time, good whitening effect, and lasting moisturizing capability, and the effective components in the cream can slowly release the nutrient components in the cream, so that the whitening effect can be maintained for a long time.

The invention relates to an antioxidant whitening cream containing tea polyphenol, which comprises the following components in parts by weight:

2.5-3.95 parts of antioxidant nano powder

0.1-0.4 part of essential oil

1.3-2.5 parts of pearl powder

4.5 to 6 portions of thickening agent

12-16 parts of humectant

0.7-1.4 parts of emulsifier

0.05 to 0.15 portion of preservative

0.05-0.07 part of vitamin

The antioxidant nano powder comprises tea polyphenol, theanine, flavonoids, pomegranate seed extract and rose extract.

Wherein the thickener can be one or more of methylcellulose, sodium alginate, pectin, and propylene glycol alginate. For example, the thickener is a mixture of sodium alginate and pectin. The thickening agent is made of raw materials with good moisturizing effect, and is beneficial to improving the moisturizing capability of the face cream.

The humectant is one or more of urea, allantoin, amino acid and sodium lactate. The humectant is natural moisturizing factor, has hygroscopicity on skin epidermal layer and horny layer, and has regulating effect on pH value of skin, and good skin affinity. The vitamin is vitamin E.

Wherein, the antioxidant nano powder comprises 1 to 1.5 portions of tea polyphenol, 0.7 to 1.1 portions of theanine, 0.2 to 0.3 portion of flavonoid, 0.4 to 0.6 portion of pomegranate seed extract and 0.2 to 0.45 portion of rose extract according to the parts by weight, such as: the antioxidant nano powder comprises, by weight, 1.2 parts of tea polyphenol, 0.9 part of theanine, 0.25 part of flavonoids, 0.5 part of pomegranate seed extract and 0.3 part of rose extract. The tea polyphenols and theanine are extracted from white tea.

The flavonoid can be one or more of myricetin, dihydromyricetin, and quercetin.

The antioxidant nanometer powder contains a lot of nutrient substances, a microcapsule technology is adopted, the nutrient substances are embedded, the nanometer structure under the hand has an antibacterial effect, in addition, the oxidation of effective components can be slowed down, the antioxidant nanometer powder is contacted with hair follicles of the skin when the face cream is smeared on the face, the nutrient substances wrapped in the sodium alginate shell are gradually emitted out and absorbed by the skin, the structure can play a slow-release effect, the stability is high, the effect of keeping the nutrients for a long time can be realized, the loss of the nutrient substances can be reduced, and the content of the nutrient substances in the face cream also needs to be improved according to needs.

The main reason for the deterioration of the cream is poor oxidation resistance and is easily oxidized during storage. The added tea polyphenol has good oxidation resistance, can protect the skin and avoid skin oxidation, and the tea polyphenol not only can help the skin to remove toxin, but also can resist external radiation, clear harmful free radicals in the skin, astringe large pores of the skin, help the skin to diminish inflammation, sterilize and resist skin aging. The tea polyphenols can reduce lipid peroxidation of skin cells, increase antioxidant level of skin, prevent cell damage caused by free radicals, and promote skin cell growth. Ultraviolet rays are the main source of free radicals of the skin, and the tea polyphenol can directly absorb the ultraviolet rays to prevent the ultraviolet rays from damaging the skin.

Tea polyphenol is extracted from tea leaves, contains various polyphenol substances including glycosides, flavans, flavonols, phenolic acids and other polyphenol components, wherein the flavonols (also called catechins) are the most main substances, have high tyrosinase inhibition rate and can stabilize the color of cream, and theanine is added, has good oxidation resistance, and can effectively solve the problem of color change of the cream during the storage period when being used together.

The key to skin whitening is to inhibit the appearance of tyrosinase, an enzyme that plays a key role in the synthesis of melanin in the body. It can catalyze L-tyrosine to add hydroxy group to transform into L-dopa; and oxidizes L-dopa to produce dopaquinone, which then synthesizes melanin through a non-enzymatic reaction. The combination of myricetin, dihydromyricetin and quercetin with tyrosinase changes the hydrophobicity and polarity around tyrosine and tryptophan residues in tyrosinase, changes the influence of the secondary structure of tyrosinase on the secondary structure of tyrosinase, can damage the structure of the active center of tyrosinase, and further causes the reduction of enzyme activity.

The flavonoids can inhibit the activity of tyrosinase, and can be used together with tea polyphenols to improve the inhibition rate of tyrosinase and ensure the oxidation resistance of cream. Tea polyphenols can whiten skin and eliminate skin color spots. Melanin is a natural ultraviolet absorbent, which can enter human cells from the skin to clear or alleviate secondary pigment deposits, chloasma, age pigment, wrinkles and the like. Preventing the skin from being aged black, has good whitening effect.

The polyphenol extract of pomegranate seed in the pomegranate seed extract is a strong antioxidant which helps to improve joint elasticity and skin elasticity, and collagen is a major protein found in the skin and has close relationship with skin texture. Pomegranate seed polyphenols help skin to resist damage from free radicals and collagen degrading enzymes. This protective effect may help to prevent premature skin wrinkle formation due to loss of skin elasticity. The rose extract can play a good role in moisturizing the skin. The pearl powder is a substance with good whitening effect and contains abundant mineral substances.

The preparation method of the antioxidant whitening cream containing tea polyphenol based on the above description comprises the following steps:

(1) dissolving tea polyphenols, theanine, flavonoids, semen Granati extract, and flos Rosae Rugosae extract in water
