ANTIOXIDANT AND BACTERICIDAL PROPERTIES OF CO2-EXTRACTS
FOR COSMETIC PRODUCTS
New trends in the cosmetic production require more serious approach to the choice
of the formulas. One shouldn't neglect the influence of cosmetics on the health
of a person, in particular, frequent cases of allergy to some components. Unfortunately,
more often the causes of it are such necessary components of cosmetic formulas
as scents and preservatives. Is there a panacea for all these troubles? In accordance
with our studies, now we can tell with confidence: yes, there is. It is the CO2-extracts.
The analysis of up-to-date world trends of perfumery-cosmetics smell evolution
shows that lately perfumers actively use spice-and-flavour aspects of the smells,
or food scents (EDIBLE). The most known of this aspect perfumes made lately, are
Lolita Lempicka (L. Lempicka Company), Angel ( T. Mugler), Casmir (Chopard) and
Wish (Chopard). When developing compositions for perfumes, the perfumers more
often use smells of honey, caramel, red fruit, cardamom, spices, green tea and
carrot. For the last novelties, these are Reur de Carotte of L'Artisan Perfumer
Company (France), - a toilet water with freshness, greenery, carrot scents against
a background of flower aroma; Oblique (Play) of Givenchy Company (France), - a
toilet water of the caramel-and-fruit aspect, etc.
As to cosmetics in which CO2-extracts are included in formulas
as biologically active additives, one can not only decrease the dozes of perfumery
scents but fully replace them. Introduction of CO2-extracts into
products in 0.5 per cent amounts regarding the total amount, allows receiving
a high-grade aroma of the spice-and-flavour aspect product.
All CO2-extracts selected for the studies, had antioxidant properties
preventing oxidation of the oil phase as a component of cosmetic products and
as own oil component.
CO2-extracts are brought into cosmetic products primarily for
satiation of a product with biologically active substances favourably influencing
skin, hair and gums.
The extracts listed above contain vitamin systems, tannins, the substances stimulating
blood circulation and thereby indirectly strengthening metabolism. They also contain
medical preventive additives.
CO2-extracts are non-polluting products combining the advantages
of a native bouquet of spicy aromatic substances which cannot be extracted by
any other extraction method. One can keep them for three years in normal conditions
without a special sealing and without losses of properties as CO2-extracts
are bactericidal.
The studies have shown that CO2-extracts do not lose their bactericidal
properties in products. When checking cosmetic products by a loading test with
such micro-organism cultures as Ps. aeruginosa, Staphylococcus aureus, Enterobacteriaceae
family at the semination level of the first ones 103 - 104 ÊÎÅ/g., bactericidal
and bacteriostatic effect of CO2- extracts was revealed. When ranging
CO2-extracts by the bactericidal ability, the sequence was received:
echinacea, Siberian fir, sage, walnut, horse-radish, siliculose pepper, zest of
orange, waste products of sea-buckthorn berries, seeds of carrots, balm citric,
greenery of parsley, olives, rosemary, cardamom, mace.
The carried out studies allow making the conclusion as follows: use of CO2-extracts
is most expedient for tooth-pastes. The extracts strengthening metabolisms alongside
with bactericidal properties, are preferable for shampoos: CO2-extracts
of siliculose pepper, horse-radish, echinacea, etc. The cosmetic creams with CO2-extracts
are enriched with biologically active substances, which in turn have an expressed
favourable influence on withering skin.
Use of CO2-extracts in the cosmetic industry solves three problems
at once:
- the extracts provide an expressed smell of a product;
- antioxidant properties of the extracts allow keeping products in a native state,
as well as indirectly increase shelf life of a product;
- the extracts contain useful substances preventing presenilation.

SUBCRITICAL ÑÎ2-EXTRACTS IN COSMETICS
Application of subcritical ÑÎ2-extracts when producing cosmetic
products raises advantages of the latter ones giving cosmetic bases various valuable
properties. ÑÎ2 extracts increase regenerating properties of creams,
develop nutritious, protective, humidifying creams, eliminate vitamin insufficiency,
lower asteatosis state of skin; the extracts also enrich the cream with biologically
active substances.
In practice, it is possible to transfer a huge variance of natural substances
to a cosmetic product as a ÑÎ2-extract or a combination of the
extracts. In addition to a healthy influence on one's skin, ÑÎ2-extracts
also provide stability of a cream in relation to oxidizing exposures, as well
as regarding the action of micro-organisms.
The lipophilia of ÑÎ2-extracts ensures superior skin action
deeply penetrating the hypodermic capillaries at molecular level.
The subcritical ÑÎ2-extracts giving the creams all of the above
properties are listed in Table 1 overleaf together with their recommended use
ratios (in percent to the total mass).
The combinations of ÑÎ2-extracts should also be of special interest
for cosmetic products development. These extracts distinguish from simple mixtures
of extracts by the fact that several kinds of vegetative raw materials are extracted
simultaneously at a specially selected ratio, forming complex and at the same
time valuable systems (blends). The matter is that during subcritical extraction
the adjustment, balancing and forming of the composition occurs at molecular level.
As a result, synergistically compatible and balanced product is received containing
aromatic, biologically active, pharmacological and other valuable components.
These blends facilitate the work of cosmeticians on creating a wide range of
biocosmetic products with targeted action, tailored for various types of skin
or for different parts of human body. We may offer a number of combinations of
ÑÎ2-extracts. The examples are given in Table 3 overleaf with the
fillings rates given in percentage of the total mass.
General recommendations on use of subcritical ÑÎ2-extracts
in cosmetic products by age groups of costumers
Infants and Young children
Child's skin is rich with blood capillaries thus it shows increased ability for
absorption. Compared to the adults, the dosage of bioadditives should be reduced
down to 10%.
Practically, only anti-inflammatory, antibacterial, antiallergic and drying remedies
are used.
Children (7 to 14 years old)
Dosages of the bioadditives are approximately 50% compared to adults.
Teenagers and Youth (up to 25 years old)
The dosages are to be increased up to 65%.
Teenage skin is especially sensitive to any infection due to metabolism imbalance
and because host defences of an organism are weak. The following actions are especially
recommended: additional nutrition of skin with vitamins and sedatives containing
anti-inflammatory, antiallergic, bactericidal and bacteriostatic components.
Adults (25 to 45 years old)
Bioadditives consumption is assumed to be equal to 100%.
Biocosmetics is used mostly preventively. Vitamin additives and bactericidal substances
are introduced.
Mature Age (over 45)
Ageing of skin is an individual process, so additives amount sometimes can be
reduced, but more often it should be increased up to 1.5 times. Devastation of
intercellular spaces results in connective tissue losing its elasticity flabbiness
of skin and nutrition disorder due to sclerosis changes in capillaries. The addition
of such bioactive substances as vitamins, hormones, trace elements, pharmacologically
active substances (anti-inflammatory, antiallergic, bactericidal, etc.) is important.

CO2 - EXTRACT OF SIBERIAN FIR
Carbon dioxide extract of the Siberian Fir is the product of extraction of green
wood pulp of the Siberian Fir by liquefied carbon dioxide (the CO2
extraction). Compared to the technologies that use organic solvents or water steam
distillation, this method offers a number of advantages: no high temperatures
are used during extraction, so the biologically active substances are not destroyed
or modified in the process, while the carbon dioxide kills all microorganisms.
CO2 extract of the Siberian Fir is substantially richer in its
composition than the oil of this species. While the Siberian Fir oil only consists
of essential oils, the CO2 extract includes in its composition,
in addition to the essential oils, just about all known lipovitamins (carotinoids,
tocopherol, provitamins F, D, K), sterols (phytohormones), flavonoids, phospholipids,
complex ethers, higher alcohols, a complex of natural organic acids, chlorophylls,
phytoncides, micro- and macro elements. Therefore, prophylactic and curative efficiency
of the biologically active substances found in CO2 extracts is
considerably higher than that of the Siberian Fir essential oil.
CO2 extract of the Siberian Fir is recommended for use in perfumery,
cosmetics, household chemicals, to manufacture personal hygiene and cosmetics
products that are very stable and preserve their original biologically active
properties. This product is an efficient preparation for health recovery, decontamination
and air deodoration. In cosmetics, CO2 extract is an attractive
option for several reasons:
- The presence of tocopherol in the CO2 extract determines its
antioxidant properties, so there is no need to add stabilizing agents while formulating
the preparation;
- The preparation possesses anti-inflammatory and regenerative effect for outer
skin and tissues.
- As antioxidant, it slows down aging processes in skin cells.
- CO2 extract of Siberian Fir has bactericidal properties and
represses the growth of many microorganisms. According to research institutes
in the pharmaceutical industry, the extract represses spore micro flora when used
in concentration above 250 mkg/ml.
- CO2 extract contains up to 48 percent of essential oils. With
its pleasant scent, the extract can be recommended for use as an odorant.
Recommended dosage: for medical treatment - 3-5 percent; as stabilizer - 1-3
percent.
CO2 extract of the Siberian Fir is used medically to treat diseases
of the upper respiratory tract, and those of the cardiovascular and peripheral
nervous system.
It is used locally to treat backaches, rheumatism, arthritis, and other malfunctions
of the skeletal and motion system of the body.
The presence of carotinoids, sterols and a vitamin complex explains the biogenic
stimulation properties of the extract. This improves metabolic processes and accelerates
epithelization of wounds. The CO2 extract of the Siberian fir has
demonstrated good properties as a medicine to heal wounds and burns, including
festering wounds and ulcers (both varicose and trophic), and to treat heel cracks.
The CO2 extract has great anti-inflammatory and regenerating effect
on the skin and tissues, it also improves the lipolytic activity in the skin.
In dentistry, the extract is used to treat paradontosis, stomatite, and other
mouth cavity diseases.
The CO2 extract of the Siberian Fir has bactericidal properties,
and represses the growth of numerous microorganisms and spore micro flora. The
needles essential oils are excellent inhaling substances with great antimicrobial
and anti-inflammatory effect, they are also an excellent preventive medicine at
the time of an flu epidemic. Foot baths help against colds and have beneficial
effect on the bioactive points of the feet, they also have favorable effect on
the entire body system. The Siberian Fir Subcritical CO2 extract
has not skin irritants properties.

PIKHTOVIT - WATER FRACTION OF CO2-EXTRACT OF SIBERIAN
FIR
The extract of Siberian Fir is an age-old and widely known folk medicine.
Decoctions of Siberian Fir young bough were used against scurvy or general malaise
as a stimulant that boosts the body's resistance functions; for their favorable
effect on the gastrointestinal tract, and to fight the pernicious effect of pathogens.
Water fraction of Siberian Silver Fir is a dark cherry-colored liquid with pleasant
fir-like scent. The water fraction constituents include: ascorbic acid, group
B vitamins, flavonoids, carotenoids, chlorophyll, polyphenols, and minerals.
The original technology allows obtaining an original product. Our water extract
of Siberian Fir is not just water solution of biologically active substances extracted
by exposing a Siberian Fir branch to water steam. It is the cellular juice taken
from the plant by liquid carbon dioxide under pressure without thermal treatment.
Water extract of Siberian Fir is a natural adaptogenic agent with a broad spectrum
of action. The product can restore physiological functions of human body, increase
its resistance against various physical, chemical and biological factors: toxic
effects of various chemicals, numerous infections, radiation damage. It also possess
anti-tumor activity.
- Siberian Fir extracts taken as medicine relieve the course of the radiation
disease, remove the symptoms of radiation damage to the body, and have hemostimulating
effect. A treatment course with Siberian Fir extract notably increases the level
of leukocytes, erythrocytes and hemoglobin in blood. Its ability to raise disease
resistance has been proved.
- The Cardiology Institute of Tomsk Research Center of the Russian Academy of
Science has examined the effect of the Siberian Fir extract in patients suffering
from neurocirculatory dystony, myocardium ischemia and arterial hypertension.
After a one-month course of Siberian Fir extract treatment, considerable improvement
was observed in patients with neurocirculatory dystony and arterial hypertension.
General condition and performance of patients was improved, their heart aches,
head aches, weakness decreased or disappeared completely. A drop in arterial tension
was registered. Positive changes in the blood composition, including lower cholesterol
and triglyceride content were observed.
- Siberian Fir extract has a clearly stimulating effect on gastric secretion.
Siberian Fir extract is efficient when used in combination with other medicines
to treat such gastrointestinal diseases as gastritis, colitis, enterocolitis,
stomach ulcer, and duodenum ulcer. After 6-8 days of extract intake, pains and
nausea in the patients disappeared, and their stool normalized. Activation of
biosynthetic processes in secretory cells of the stomach mucosa resulted in rapid
normalization of secreting activity. It has been proved that the Siberian Fir
extract can be used as a principal medication in cases where the stomach ulcer
is up to 5 mm, and in larger ulcerous cases it can be used as complementary to
the standard treatment plan.
- The formulation was useful in the complex treatment of patients in proctology,
against rectum fistulas, proctitis, festering wounds and inflammatory processes
in the intestinal mucosa. This effect is expressed through accelerated purification
of festering wounds, active stimulation of granulating processes, immune system
stimulation. In the groups of patients where the Siberian Fir extract was administered
in combination with conventional treatment, recovery occurred 5-7 days earlier.
- The Siberian Fir extract has been successfully used to treat lung disease
and upper respiratory tract disease (such as bronchitis, tonsillitis, pneumonia,
tuberculosis). The preparation eliminates inflammatory processes in the bronchi-lung
system. Conifers are known to contain phytoncide complexes that have destructive
effect on the microflora. Using 6 strains of different microorganisms, it was
proved experimentally, that the extract of the Siberian Fir slows down their growth
and development by 70 to 150 times. The Siberian Fir extract is used for complex
treatment of the lungs, primarily to reduce side effect caused by tuberculostatic
drugs intake.
- Skin application of the extract in case of burns or dermatitis rapidly eliminates
growing pathological process and prevents any possible recurrences. In case of
mucous membrane injuries (erosions or ulcers), the Siberian Fir extract causes
fast granulation of the injured areas.
In this way, water extract of the Siberian Fir stimulates blood generation, the
body's immunity system and regeneration processes, it has antimicrobial, anti-inflammatory,
hepatoprotective, anti-ulcer, and anti-radiation effects, it improves the functions
of the respiratory and gastrointestinal tracts. The preparation is not toxic and
has no allergic, carcinogenic or teratogenic properties.
Practice:
To make the recommended weekly dose, use 5-10 ml or 1-2 teaspoons of Pikhtovit
per 1 liter of water.
Take 1/4 to 1/2 glass twice a day with the meal. The treatment course duration
is 2-4 weeks.
