    NATRASORB BATH starch is an oil absorbing powder which is able to absorb and carry large quantities of oils and anhydrous liquids, such as bath oils. The starch is processed in a manner that creates unique 'pockets' that can carry the oils essentially in a solid, powder form.

    NATRASORB BATH starch is hydrophilic so that once the starch comes in contact with water, it immediately dissolves releasing loaded oils, fragrances and/or emulsifiers, dispersing them into the warm water. The starch itself provides a soft feel to the bath water, but does not settle or leave a film.

    NATRASORB BATH, which dissolves in water, is used as a fragrance fixative in bath salts/powders and may also allow the salt not to clump and remain free flowing. It?s used in bath bombs/fizzies, bath salts/powders, milk baths, body powders and other toiletries.

    Store in a cool, dry location away from heat, sparks or fire. Good hygiene practices should be followed when working with this product. Shelf life: 2 years.

    Appearance: White to off-white free flowing powder.

    Applications: Bath & Shower Products, Powder.

    Functions: Naturally derived. Water activated, oil & fragrance delivery.

    INCI: Tapioca Starch. Manufactured in the U.S.A.. This product is not Natrasorb HFB, that's a different product.

    ************************** What Is Natrasorb and How Do I Use It?

    Have you seen Natrasorb on our site and been curious if it would work well for you –but weren’t quite sure how to use it?

    Natrasorb has an INCI description of “tapioca starch”. However, it is not the kind of tapioca starch you can buy in a grocery store.

    Rather, it is a variety of tapioca starch that has been modified to hold a LOT of oils –both carrier oils for added moisture and essential/fragrance oils for added scent and aromatherapy benefits. It’s still in a powdered state, and is hydrophilic (water loving).

    Whether you make bath fizzies, bath salts or bath powder, Natrasorbcan really help to enhance the fragrance in your product. You can use it, for instance, as 5% of your bath bomb recipe, and then add another 3% (by weight) of fragrance oil to the recipe.

    The mixture will look like nothing has happened, but all of a sudden, it is MUCH more fragrant, and the fragrance is long lasting! You simply measure out your fragrance, add about twice that amount of Natrasorb(by weight), and mix the fragrance into the Natrasorbuntil it is evenly dispersed.

    The mixture should not clump when you squeeze it together, but it may be slightly sticky. (Please take care to use only as muchNatrasorbas you need, as using an excessive amount may cause your recipe to become too sticky and less free-flowing than you like. ) Then you blend the rest of your ingredients with your scented Natrasorb. :->

    Here are some recipes using Natrasorbto get you started:


    1 cup Epsom Salts

    ½ cup Sea Salt (small or medium grain will be most comfortable in the bath …)

    1 Tablespoon NatrasorbBath

    20 drops essential or fragrance oils of choice

    1.Start by placing the Natrasorbin a bowl and mixing in the essential oil/fragrance oil until it is fully absorbed. The mixture should resemble fine breadcrumbs.

    2.Combine the essential oil/fragrance oil/Natrasorbmixture with the sea salt and Epsom salts and combine to mix well.

    3.Seal mixture in a humidity-proof pouch and enjoy!

    ****FIZZING BATH SALTS WITH NATRASORB BATH (all parts by weight):

    66% Epsom Salts

    20% Baking Soda

    10% Citric Acid

    3% NatrasorbBath

    1% essential or fragrance oils of choice

    1.Follow directions in previous recipe to combine NatrasorbBath with essential/fragrance oils.

    2.Add rest of ingredient and mix.

    3.Seal mixture in a humidity-proof pouch and enjoy!

    P.S. There is another product called NatrasorbHFB, which serves the same basic function but has a different INCI and the added ingredients Aluminum Starch Octenylsuccinateand Acrylates Copolymer and Magnesium Carbonate. These instructions and recipes are strictly for NatrasorbBath, not NatrasorbHFB.

    Works great!

    I bought this product out of curiosity, as I had never heard of anything like it! I added it when making a bath tea for a gift. Not only did I add Essential Oils to it, but I also added a bit of carrier oil and was shocked when this powder sucked it right up! I used recommended amount in the product description. It has been three months since I made the bath tea, and it still smells as fragrant as when I first made it. Essential oils are great but the scent can dissipate fast. This powder truly locks in the scent. I couldn't be more pleased.
    absolute must have for bath products

    Even as I write this review, a full three years after the previous one, it still holds true that this FANTASTIC product is extremely difficult to find and CG is the only supplier that carries it at such a good price. I ordered way too little when I placed my last order and can't wait to get more of this because I have been incredibly pleased with its ease of use and efficacy for custom-made bath products. it is so versatile that it can even be used in foot- and body scrubs. Nothing else carries EOs as well as this.
    Great Stuff

    I really love this stuff and it is pretty hard to find. I use it in bath salts and dry shampoo and I am thinking about testing it in a deodorant recipe. It expands a lot so you will get a lot of use out of this product.
    Must Have!

    This Natrasorb was not only hard to find in stock anywhere else, but Camden-Grey has the best price in stock! So glad I found this stuff, it helped fix a recipe for bubble bars I've been working on for months. Problem solved!
    Great for E.O. dispercement!

    This particular product is how I found Camden Grey. They are the only site I've found, other than 1, to carry this light fluffy powder. They definitely offer it at the best price! I have used this product in my bath salts from day 1. I wouldn't make them without it! It holds the scent of your E.O.s much better than salts alone. Helps disperse your oils into your bath water instead of on top.

    Thanks for browsing thru this section which contains answers to many questions that are often asked of us. Here we explain where to locate CofA and SDS for a product, how we dispense and package our products, how products should be stored, basic terminology and the wait time for bulk products to ship from our warehouse. FYI: We're closed on Fridays.

    Certificate of Analysis (CofA) and Safety Data Sheet (SDS). We publish on our website those documents for most of our products, some products don't provide either because the product doesn't require it. In this same section where you're at now, look to the tab to the left titled Documents, click on it and that's where you'll find either document for the product you seek. If you do not find the document you require, please email us at so we can research further.

    BULK ITEMS: When a customer adds a bulk item to the cart, the customer’s immediately shown on the screen how many number of days should be allowed for the bulk product to arrive at our warehouse. If the bulk item happens to be in stock, we’ll ship sooner than the customer would expect. As we emerge from Covid, logistics operations are not yet back to normal, what used to arrive at our warehouse in 3 days now takes much longer. Should a vendor inform us the ordered product will take longer than what’s mentioned on our website we’ll email the customer with the latest information.


    EO = essential oil

    FO = fragrance oil



    Essential oils: in 1/32 oz. to 1/4 oz...amber glass vials with orifice reducers. ½ oz. to 2 amber glass bottles with white caps and Eurodroppers...3 to 4 oz. in amber glass bottles with black caps and without orifice reducers...7 oz. in aluminum bottles...15 oz. in amber glass bottles with black caps...10 & 25 lbs. in HDPE plastic containers with wide mouths although, occasionally, 25 lbs. may be dispensed in factory-issued metal containers with pouring spouts.

    28 lbs. of carrier oils and other liquids are dispensed in individual HDPE plastic gallon containers with handles, each holds the purchased net weight of liquid.

    30+ lbs. of carrier oils, other liquids, soft butters, Castile gel and other products are dispensed in plastic HDPE pails w/metal handles & pouring spouts in the lid; those products may remain inside the pails indefinitely when properly stored. After Covid, we reserve the right to use any packaging/dispensing container available to us and not mentioned above because it continues to be difficult many times to restock the same packaging container or material used in the past.

    NOTE: An EO may safely remain inside an aluminum container for up to 3 months, but if storing longer than 3 months the oil should be transferred to amber glass. Fragrances and carrier oils up to 8 lbs. may remain inside HDPE plastic bottles indefinitely. If the customer at any time feels more comfortable transferring a product to glass this should be done. ALL PRODUCTS ARE DISPENSED BY WEIGHT, THUS, SOME CONTAINERS MAY BE FILLED HIGHER THAN OTHERS DEPENDING ON THE WEIGHT AND VISCOSITY OF EACH PRODUCT.

    Raw materials/ingredients are dispensed by weight. Many customers ask how many ounces in a pound, there are 16 ounces in one pound. These are not fluid ounces, they are ounces by weight.

    HOW TO STORE: EOs, FOs and BUTTERS should be stored in tightly-sealed containers away from direct light and heat. Some EOs could be highly flammable, keep away from open flames. Keep all liquids and powders you purchase from Camden-Grey tightly capped and away from the reach of children, the elderly or infirm and pets. Refrigerating butters could adversely affect the consistency of the butter, please join our Forum if you need to learn how to handle, work with and store products.
