In this blog post, we discuss: 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 use lubricant correctly on a sex doll.
What 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 stays smooth for a long time.
- Easy to wash off with water.
- Ideal for people with sensitive skin or allergies.
- Leaving no stains or harmful residues on the doll.
- Disadvantages:
- Dries faster than silicone-based or oil-based lubricants, which require repeated applications.
- Less suitable for long-term, intensive activities without supplementing.
- Suitable for: TPE and silicone sex dolls, ideal for those who value safety and skin friendliness.
Silicone-based lubricant
- Advantages:
- Very smooth and long-lasting effective, even under water.
- Usually dries out less quickly, allowing for long-term use.
- Suitable for more intensive, longer sessions.
- Disadvantages:
- Will damage silicone or TPE sex dolls if used more than once, as the silicone will corrode or degrade.
- More difficult to wash off; leaves residue.
- Not suitable for use with silicone toys as it will affect the texture.
- Suitable for: Not for silicone or TPE sex dolls.
Oil-based lubricant
- Advantages:
- Very smooth and provides hours of lubrication.
- Good for people who are sensitive to other types of lubricants.
- Cheap and often readily 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 doesn't 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 not suitable for sex dolls, as 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. Therefore, always check with the webshop where you order from, or use our own TPE lubricant, specially developed 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 will damage the materials of your doll, such as silicone or TPE. This leads to accelerated wear and tear and makes the doll vulnerable to cracking or deformation. Using an unsuitable lubricant will shorten the lifespan of your sex doll by one to two years. Furthermore, the right lubricant provides a more realistic experience, as it glides smoothly and mimics the feeling of skin on skin.
This significantly increases the pleasure of using your sex doll. Monica Moments offers a specially developed lubricant, the Doll & Toy Lube , for safe and long-lasting use with sex dolls. This lubricant is suitable for both silicone and TPE dolls, so you're always guaranteed a soft and safe experience.
What should you pay attention to when choosing a lubricant?
When choosing a lubricant, consider compatibility, longevity, ease of cleaning, ingredients, and pH:
- Compatibility: Always use water-based lubricants for TPE and silicone dolls, as oil- and silicone-based lubricants can damage the material. Always check the product information to avoid damaging the doll.
- Long-lasting effect: Choose a thicker, water-based formula that won't dry quickly and requires less frequent reapplication. Avoid thin or alcohol-based lubricants that evaporate quickly.
- Ease of cleaning: Choose a water-soluble lubricant that washes off easily without leaving a sticky or greasy residue. This prevents dirt and bacteria buildup.
- Safe ingredients: Avoid lubricants with perfumes, glycerin, or harsh chemicals, as these can irritate your skin and damage the doll's material. ( 1 ) Choose a hypoallergenic, unscented option.
- pH: 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 store-brand lubricant contains only four ingredients and is simple, effective, sustainable, natural, and harmless.
By considering these factors, you'll ensure that your lubricant not only feels comfortable but also guarantees safe and long-term use without damaging your sex doll.
How to use lubricant correctly in 4 steps
To use lubricant on a sex doll, apply 5ml of lubricant to the desired areas where friction occurs, such as the intimate areas. 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 distributes evenly.
- Apply a small amount of lubricant. Use about a teaspoon (5 ml) per area, squeezing the bottle gently to avoid applying too much. Too much can leave a sticky residue and be 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 strain the material.
- Clean the sex doll after use. Carefully remove any lubricant residue 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.
By following these steps, your sex doll will stay in good condition and you will optimally enjoy the use of lubricant.
