In this blog we cover: why a good lubricant is important for a sex doll, which types of lubricant are suitable for sex dolls, what to look for when choosing a lubricant, and how to properly use lubricant on a sex doll.
Which types of lubricant are suitable for sex dolls?
Each type of lubricant has specific properties that make it more suitable for different materials, such as TPE (thermoplastic elastomer) and silicone. Below we discuss the pros and cons of each type of lubricant and which material they are best suited for.
Water-based lubricant
- Advantages:
- Safe for use on both TPE and silicone.
- Does not dry out quickly and remains smooth for a long time.
- Easy to wash off with water.
- Ideal for people with sensitive skin or allergies.
- Leaves no stains or harmful residues on the doll.
- Disadvantages:
- Dries faster than silicone or oil-based lubricants, requiring repeated application.
- Less suitable for long, intensive activities without reapplication.
- Suitable for: TPE and silicone sex dolls, ideal for those who prioritize safety and skin-friendliness.
Silicone-based lubricant
- Advantages:
- Very smooth and long-lasting, even underwater.
- Usually dries out less quickly, allowing prolonged use.
- Suitable for more intensive, long-lasting sessions.
- Disadvantages:
- Causes damage to silicone or TPE sex dolls with more than one use, as it will degrade or harm silicone.
- Harder to wash off; leaves residue.
- Not suitable for use with silicone toys, as it affects the texture.
- Suitable for: Not for silicone or TPE sex dolls.
Oil-based lubricant
- Advantages:
- Very smooth and provides lubrication for hours.
- Good for people sensitive to other types of lubricants.
- Cheap and often easily available.
- Disadvantages:
- Harmful to both TPE and silicone, as it breaks down or makes the material porous.
- Difficult to wash off and stains bedding or clothing.
- Not suitable for use with latex or rubber products.
- Suitable for: Not recommended for TPE and silicone sex dolls, as it damages the integrity of the material.
Conclusion:
Water-based lubricant is the safest choice for both TPE and silicone sex dolls, as it does not damage the material and is easy to wash off.
Silicone-based lubricant is not a good alternative for TPE dolls and should also be avoided with silicone dolls to prevent damage. Oil-based lubricant is also unsuitable for sex dolls because it damages the material and is difficult to remove.
Note: Although water-based lubricant is the best option of the three, some ingredients may still be harmful to TPE. Always check with the webshop where you order or use our specially developed TPE lubricant made specifically for our sex dolls.
Why is good lubricant important?
Good lubricant is important because it not only increases comfort but also protects the lifespan of your sex doll. Using the wrong lubricant can damage your doll’s materials, such as silicone or TPE. This leads to accelerated wear and makes the doll vulnerable to tears or deformation. Using an unsuitable lubricant shortens your sex doll’s lifespan by 1 to 2 years. Additionally, the right lubricant provides a more realistic experience because it glides smoothly and mimics the feeling of skin on skin.
This significantly enhances the enjoyment of using your sex doll. Monica Moments offers a specially developed lubricant, the Doll & toy lube, designed for safe and long-lasting use with sex dolls. This lubricant is suitable for both silicone and TPE dolls, ensuring a soft and safe experience every time.
What should you look for when choosing a lubricant?
When choosing lubricant, pay attention to compatibility, longevity, ease of cleaning, ingredients, and pH value:
- Compatibility: Always use water-based lubricant for TPE and silicone dolls, as oil- and silicone-based lubricants can damage the material. Always check the product information to prevent damage to the doll.
- Long-lasting effect: Opt for a thicker water-based formula that doesn’t dry out quickly and requires less frequent reapplication. Avoid thin or alcohol-based lubricants that evaporate quickly.
- Ease of cleaning: Choose a water-soluble lubricant that is easy to wash off without leaving sticky or greasy residues. This prevents the buildup of dirt and bacteria.
- Safe ingredients: Avoid lubricants with perfumes, glycerin, or harsh chemicals, as these can irritate the skin and damage the doll's material. (1Choose a hypoallergenic, odorless option.
- pH value: Choose a neutral pH lubricant (between 4 and 5) to maintain the doll’s texture and prevent skin irritation.
- Ingredients: Choose a lubricant without perfume, spermicides, flavorings, unnecessary additives, or toxic ingredients. Our house brand lubricant contains only four ingredients and is simple, effective, sustainable, natural, and non-harmful.
By considering these factors, you ensure your lubricant not only feels pleasant but also guarantees safe and long-lasting use without damaging your sex doll.
How to use lubricant correctly in 4 steps
You use lubricant on a sex doll by applying 5 ml of lubricant to the desired areas where friction occurs, such as intimate zones. This ensures a smoother experience and prevents damage to the doll’s material.
Step-by-step plan:
- Clean the surface. Make sure the sex doll is clean and dry before applying lubricant. Use a mild cleanser to remove dirt and dust so the lubricant adheres better and spreads evenly.
- Apply a small amount of lubricant. Use about a teaspoon (5 ml) per area and gently squeeze the bottle to avoid applying too much. Excess can leave a sticky residue and is harder to clean.
- Distribute the lubricant evenly. Spread the lubricant over the desired areas with your hands or a clean cloth. This ensures a smooth experience and prevents uneven distribution that can stress the material.
- Clean the sex doll after use. Wash off all lubricant residues carefully with lukewarm water and mild soap. Avoid harsh cleaning agents like alcohol, which can damage the material. Let the doll dry completely before storing to prevent mold growth.
By following these steps, your sex doll stays in good condition and you can fully enjoy using lubricant.
