Product Description

Product Description

EcoSilk MB (Isoamyl Laurate) is a versatile, vegetable-derived emollient that transforms the feel of your skincare and haircare products. Made through the esterification of isoamyl alcohol and lauric acid from sustainable sources like sugar beet and coconut, barley and wheat, EcoSilk MB offers a lightweight, non-greasy alternative to synthetic emollients.

It dramatically improves the skin feel of formulations containing heavier oils, waxes, and butters, making them lighter, smoother, and more elegant to apply. Isoamyl Laurate is found in numerous products, including hair conditioners and skin care items. From baby balms to SPF day creams and deodorants,

EcoSilk MB enhances product performance and texture without compromising on natural standards.

Ideal for modern cosmetic formulations, EcoSilk MB is especially valuable when creating emulsions, oil blends, and colour cosmetics. Its ability to disperse pigments and powders evenly and its various functions as an emollient and skin conditioning agent make it a go-to ingredient for high-performance skincare and makeup products.

Whether you’re formulating a nourishing face cream or a silky hair serum, EcoSilk MB offers a natural, sustainable way to enhance spreadability and skin feel, with zero stickiness. Isoamyl Laurate is a non-volatile, oily liquid that provides a protective barrier and is touted as a natural alternative to silicones.

Product description for beginners

Product description for beginners

Ecosilk MB improves the spreadability of oils and dramatically improves the textures of creams and butters that have been made with high amounts of vegetable oils, butters and waxes by making them feel lighter and more elegant to the touch.   This is very useful when adding high amounts of sticky materials like Vitamin E and also in baby products like nappy balms.   It has always been a problem for aromatherapists, to blend vegetable oils together to have, not only the desired therapeutic effect, but also an elegant skin feel.   Combining the fattier oils like Shea Butter oil with drier oils like Rosehip Seed oil goes a long way to creating a more sensory feel.   However, sticky oil like Castor oil or Vitamin E have exceptional functions but feel unpleasant.   Up until now, Squalane has helped a lot, but that was only useful for skincare products.   Now we have EcoSilk MB, it is possible to create elegant oil blends for hair and skincare.   The MB in EcoSilk MB stands for Mass Balance meaning that the Palm Oil used in the production of EcoSilk MB comes from a CSPO (Certified Sustainable Palm Oil) supply chain which is now mandatory for COSMOS approved ingredients and products.   The INCI for EcoSilk MB is just Isoamyl Laurate which represents the full nature and composition of the material as Isoamyl alcohol (from sugar cane, sugar beet, wheat, barley) and Lauric acid (from sustainable Palm oil) go through an esterification process to produce Isoamyl Laurate.

According to the Cosmetic Ingredient Database (CosIng), the functions of Isoamyl Laurate are: Emollient, Skin Conditioning.

How to use it

How to Use

Skin Care

• It has a degreasing effect for the stickiest of vegetable oils like Castor oil. This means that the wonderful benefits of Castor oil can be used without the product feeling unpleasant.
  
  
• Use in massage oil blends and eye makeup cleansers, and makeup removers.
  
  
• It gives a very elegant feel, much better than the synthetic silicones do.
  
  
• Use in very heavy formulations such as vitamin-enriched night creams and butters so that they feel lighter on the skin.
  
  
• The sunscreens used to give Sun Protection Factor (SPF) can be difficult to work with as they make a cream feel heavy and pasty.
  
  
• EcoSilk MB is very effective at dispersing powders such as Titanium Dioxide and makes the finished cream spread across the skin better, feeling light and comfortable.
  
  
• It also reduces the whitening or ghosting effect that such creams can have, meaning you can formulate higher SPF.
  
  
• Day Creams with high SPF will feel light and sheer.
• It is an extremely effective waterproof makeup remover that does not irritate the eyes.
  
  
• It can easily transform water in oil (W/O) emulsions into light emulsions that can almost not be distinguished from an oil in water (O/W) emulsion.
  
  
• Excellent dispersing agent for colour pigments in colour cosmetics.
  
  
• Good to use in deodorants.
  
  
• Often, a heavy oil like Castor oil is used sparingly so that it does not sink into the skin when applying a deodorant.

• EcoSilk MB will make this feel so much more silky rather than sticky.
  
  
• EcoSilk MB helps to mix difficult ingredients and helps to reduce oil separation in emulsions; therefore, we would consider it a helper emulsifier.
  
  
• It can also help to clarify bath oils.

Hair Care

• It has a great hair conditioning effect, just as effective as the synthetic silicones.
  
  
• In hair products, it leaves hair silky and smooth and makes extremely good hair serums.
  
  
• Although stated as heat stable up to 66°C, we have been using it extensively, and it appears to tolerate heat styling products well.

Other

• Use 1% to 100%. Soluble in oil and ethanol.
  
  
• Not suitable for use in water-only products like toners.
  
  
• Use in Face and Body Oils, Massage Oils and Gels that contain some oil.
  
  
• Heat stable up to 66°C, so we recommend using it in Stage 3 when making creams, lotions and body butters.
  
  
• Use at 1% to 10% in creams and lotions.
  
  
• Use up to 50% when combined with oil to make dispersible bath oil blends.
  
  
• Combine with equal parts Argan oil and Broccoli Seed oil for a conditioning hair dressing to scrunch through dry hair.
  
  
• This gives condition and shine. Add 6% to any blend of massage oils to make it feel more silky.
