The SYLK® Formula with Nature’s Wonder Ingredient

SYLK® is the only all natural moisturizing lubricant on the market made with New Zealand kiwifruit plant extract. The benefits of using SYLK® include enhancement, supplementing the body’s natural lubrication, and relief from symptoms such as vaginal dryness (Atrophic Vaginitis).


The SYLK® formula is made with kiwifruit plant extract that is harvested from orchards in the Province of Auckland, New Zealand. Kiwifruit plant contains an inherent ingredient known as polysaccharides; through our proprietary extract process, we collect the natural film-like lubricant which is similar to that of what the body produces. Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages and on hydrolysis which give the constituent monosaccharides or oligosaccharides.

Furthermore, these natural water-based polymers are used in SYLK® as a health-conscious alternative to that of parabens, which are derived from petroleum. Parabens are seen to be harmful due to their xenoestrogen qualities, which may mimic and disrupt hormone balance in the body and can lead to reproductive issues. In a recent study, Dr. Philippa Darbe found the presence of parabens in the breast tissues of all 40 women she sampled who were undergoing a mastectomy. With the absence of parabens in the SYLK® formula, consumers will not experience the harmful side effects associated with the use of parabens and other synthetic chemicals.

Potassium Sorbate, Citric Acid, and Sodium Citrate

The SYLK® formula also contains potassium sorbate (PS) to prolong shelf life and to inhibit harmful bacteria from forming in the product. The potassium sorbate used in SYLK® is a natural compound derived from fruits and vegetables. A study was conducted where scientists added 100 ppm, 500 ppm, and 1000 ppm of potassium sorbate into cokelek (a traditional dairy product). Their lab testings found that when potassium sorbate of 500 and 1000 ppm were added in solution, it was able to inhibit yeast-mold and the bacteria enterococci. The SYLK® formula contains more than 1,000 g of potassium sorbate in a 1,000 liter bulk blend. This is well over the needed amount to enhance its shelf life.

The SYLK® formula also includes natural preservatives such as citric acid and sodium citrate, which are intended to optimize the pH of SYLK®. Scientific research has found that in solution, lowering the pH or increasing the concentration of preservatives also enhances the ability to inhibit bacterial growth in our product (Restaino et al., 1981; Bulgarian Journal of Agricultural Sciences). Lowering the pH in solution with citric acid and sodium citrate regulates the pH of SYLK® to support proper pH in the vagina.

A healthy vagina has an acidic pH of 3.8 to 4.5. The presence of excess bad bacteria in the vagina causes the pH to be greater than 4.5, which may lead to symptoms such as bacterial vaginosis. SYLK® supports a balanced vaginal pH.

Flavonoids (Grapefruit seed extract)

One of the key ingredients used in the SYLK(R) formula is grapefruit seed extract (GSE), which contains the flavone naringenin. Flavonoids are groups of plant metabolites that are found in many fruits and vegetables. Flavonoids have been reported in the scientific literature to have limited anti-inflammatory, antimicrobial, antiviral, and anti-allergic activities. They are also known to have antioxidant properties and may help the body fight harmful free radical cells. The flavonoid naringenin is seen to give grapefruit its ability to inhibit microbes (Dembinsky et al., 2004).

Huang-chin, an ancient herb used in China, contains another type of flavone called baicalein. Scientists Tsao, Newman, Kwok, and Horikoshi found that this plant’s antimicrobial properties is mostly due to the flavone baicalein that exists in huang-chin.

Life Conditions of those who use SYLK®

The SYLK® formula is a multi-purpose product, designed to enhance sexual wellness no matter the life stage. SYLK® can be applied to women who have the following life conditions such as vaginal dryness/ Atrophic Vaginitis (AV) and Bacterial Vaginosis (BV). The application of SYLK® can help to temporarily relieve symptoms of atrophic vaginitis, vaginal dryness, itching, burning, soreness, and pain during intercourse.

Bacterial Vaginosis may occur when the bad bacteria overpower the good bacteria, thus upsetting the pH balance in the vaginal organ. Atrophic vaginitis may occur when there is hormone imbalance in the body. This usually takes place during menopause, for a balanced estrogen level helps the body maintain lubricating fluids in the vagina. According to a Jane Minkin, M.D., a gynecology Yale clinical professor, 70 to 80 percent of pre and postmenopausal women will have this condition. When the vaginal lining becomes thin and inelastic, it leads to a constant dryness known as vaginal atrophy. A lowering of estrogen level and the thinning of vaginal walls can also be due to childbirth/ breastfeeding, exposure to radiation and chemotherapy, anti-estrogen medication, and surgical removal of ovaries.

Vaginal dryness can be caused by factors other than a hormonal imbalance. The chemicals found in detergents, soaps, or unnatural lubricants can also irritate the vagina and result in dryness. Allergy and cold medicines that contain decongestants and antihistamines can decrease moisture in the body. Those experiencing anxiety, stress, or depression may also experience dryness in their vaginal area. Dr. Goldstein of Alvarado Hospital states that a women has insufficient blood flow when she becomes anxious. Stress can also change the body’s internal chemistry, including the hormonal balance.

Causes of AV and BV:

  • Menopause
  • Hormones imbalance
  • Childbearing or breastfeeding
  • Stress, anxiety, or depression
  • Imbalance in vaginal pH
  • Allergy and cold medicines
  • Antihistamines
  • Chemotherapy/exposure to radiation
  • Women in postnatal/postpartum
  • Candida albicans
  • Multiple sex partners, and more...

Why New Zealand Kiwi?

New Zealand is the third largest producer of kiwi in the global market. This is largely due to northern New Zealand’s temperate climate, its close proximity to volcanoes, and its long term commitment and experience in growing this fruit. Several factors are needed for optimal kiwifruit growth, which is why New Zealand is the preferred source over other countries. Firstly, kiwis are best grown in a temperate climate. With an abundant amount of irrigation, they can withstand a maximum of 114°F in the summer and a minimum of 27°F in the winter. Anything lower than that will damage the vines. The soil must be well drained and have a pH of between 5.5 and 7.2 in order to grow good kiwifruit.

In addition, kiwi orchards need to have adequate shelter from the wind, for wind can break the growing shoots and delay production. Frost in the fall and spring will also damage the plant’s vine, resulting in death; thus, a kiwi plant needs around 240 days free of frost.

Most of New Zealand’s agricultural production takes place in the Bay of Plenty and Auckland provinces located in the upper coast of North Island. These areas are some of the warmest regions of New Zealand, averaging 56°F in the winter and 78-90°F in the summer. Sunshine is plentiful, with most areas experiencing 2,000 hours of sunshine per year.

Volcanic Activity

New Zealand’s abundance in agriculture is also due to the country’s volcanic activity. The region of active volcanoes, called Taupo volcanic zone, located in the realm of the North Island. In the short-term, volcanic activity is damaging to the ecological environment. Ashes from the volcano may bury or break the stems, thus hindering the plant from photosynthesis. However, these very same ashes are beneficial for New Zealand’s soil in the long-term. Agriculture in the Bay of Plenty region is grown on volcanic loams where volcanoes have erupted 4,000-40,000 years ago.

The properties found in volcanic soils allow for greater creation of capillaries. These capillaries give the soil more porosity and a lower density, thus allowing it to hold more water (Ping 2000). The retention of phosphorus in volcanic soils allows the soil to be more fertile, which then produces more crop yield. Volcanic soils also have a pH between 5-7, allowing it to grow the optimum kiwifruit which needs a pH lower than 7.3 to grow.
