We’re so glad you asked! SYLK is the only water-based moisturizing lubricant formula made with 100% purified natural New Zealand kiwifruit vine extract. The vine extract replicates the vagina’s natural, healthy pH balance and is very similar to natural lubrication. Combined with 7 other ingredients, SYLK is designed to mimic the body’s natural lubrication and feels oh-so smooth.
Aqua (Deionized Water)
Kiwifruit vine extract – (Polysaccharides) The Kiwifruit Vine extract yields a high amount of pectic polysaccharides. Polysaccharides are polymeric carbohydrate molecules. When extracted from the kiwi vine, polysaccharides are “film-like” and provide an exceptional form of lubrication and are similar to the natural lubricant produced by the body. SYLK is made with 100% purified natural kiwi vine extract.
Vegetable glycerin: is a humectant, which is a substance that attracts moisture to the skin. **See our FAQ on glycerin**
Xanthan gum – is a widely used food-grade ingredient used as a thickening agent.
Potassium Sorbate and Sodium Citrate – Trace amounts of preservatives to prolong the shelf life of SYLK.
Citric Acid – Intended to adjust the pH of SYLK.
Flavonoids (Grapefruit Seed Extract, GSE) – Flavonoids are groups of plant metabolites that are found in many fruits and vegetables. Flavonoids have been reported to have anti-microbial, anti-viral, anti-inflammatory and anti-allergic activities and is used to preserve SYLK.
Petroleum or petroleum-based ingredients. These ingredients can coat the skin with a barrier that interferes with its normal functions and permeability.
Parabens. Parabens are common chemical preservatives found in everything from food to shampoo. They have been used by cosmetic and pharmaceutical companies for many years and are considered safe. In recent years, some research has suggested parabens disrupt hormones in people and the environment, and they have been found in cancer tumours. Many consumers now choose to buy paraben free products.
Propylene glycol. This potentially toxic ingredient may cause some women to experience tissue irritation (chemical also found in some types of antifreeze).
Hydroxides. Commonly found in lubricants for pH balance, these ingredients are so powerful they are used in cleaners and are strong irritants.
Prescription is not needed 🙂
In order to legally sell a personal lubricant to consumers in the United States, a company must notify the FDA of its intent to manufacture and sell the product and make sure that the product has gone through the proper due diligence and testing to ensure that the ingredients will not harm people. Personal lubricants are considered a Class II Medical Device and it’s important for consumers to know that their personal lubricant has been FDA Cleared.

SYLK® has a pH of approximately 4.5, which is similar to normal vaginal pH of 3.5-4.5. Normal vaginal pH indicates that there is the right amount of good bacteria (lactobacilli), and no overgrowth of the bad bacteria that can cause odor, irritation and sometimes infection. Afterall, life’s all about balance, right?!
The most important factors that can alter the vaginal environment are two things called osmolality and pH.
In terms of a personal lubricant, osmolality refers to the product’s ability to draw moisture from the skin and pH refers to how acidic or alkaline the product is.
So here’s the bottom line: If the osmolality and pH of your lubricant are acceptable and in-balance (like SYLK), the insignificant amount of vegetable glycerin in the product is inconsequential.
SYLK is an FDA 510(k) Cleared product, proving its longstanding record of safety and effectiveness. Each batch is reliably and consistently tested to ensure that it is in the acceptable ranges for osmolality and pH according to the World Health Organization.
SYLK is a gentle water- based lubricant and compatible with latex, polyisoprene, and polyurethane condoms.
Nope! SYLK does not have any added flavors or fragrances.
Oh Yeah! See our ingredients FAQ for what’s in SYLK!
SYLK is safe and can be used throughout pregnancy and while breastfeeding. While SYLK is not a spermicide and does not harm you, the pH balance of SYLK can affect the movement of sperm (like many other lubricants) and is not recommended to use while trying to conceive.
We always recommend speaking with your doctor before using any products during pregnancy.
SYLK is made with the kiwi vine, not the fruit so this should not be a problem. However, we recommend a patch test on your inner arm/wrist just to be safe.
No way! SYLK’s proprietary ingredient, the kiwifruit vine extract, is truly nature’s wonder ingredient for personal lubricants. It’s what gives SYLK its slick, film-like texture without leaving a sticky or tacky residue. Remember: a little goes a LONG way so start with a few drops to avoid stickiness. Need a refresh? Just add a little water.
Nope! Generally, one application is enough as SYLK’s slipperiness reactivates when it comes into contact with your body’s own moisture. Should you wish to boost your glide (or have an extended “session”), add a little water or a second application. Wetter is better, after all 😉
Yes, SYLK is a water-based lubricant that can be used by men with or without a partner.
SYLK should be stored at room temperature about 66-77°F (19-25°C) and out of direct sunlight. Be sure to close the cap for purity.
