  • Rice Starch vs Rice Flour

    The final product will be anhydrous powder (like dry shampoo) what would be recommended to use rice flour or rice starch. I have had a tough time finding rice flour with low micro counts (<1000 cfu).

    hi in rice flour you have around 75-80% of starch content. 25-20 % are other components. I would use Rice Starch for a Dry shampoo base because you want the absorption part of the Rice Flour and that’s the starch so way use the other part that just adds stuff that can course problems to your formulation 🙂

    Thank you for the info. Just another question, so the rice starch is just a more pure form of the rice. This would be concentrated. Are there any tests to prove the rice starch potency? Would this be needed in a finished product?

    Would too much starch burn the hair or be considered an overload of active?

    hi sorry for the late replay but it’s the holiday season 🙂

    Well, not a concentrated version just a Purified one.

    And the test for the product is a little difficult too much can lead to mattified hair which is mostly not targeted by hair products. but the problem is that this will depend very much on the hair type and the person that is using your Product.

    the Amount to use depends on the Product type you are making. if you want to make an old fashion “i don’t need to wash my hair for a few days because I am on holiday and don’t have the ability to do that” you need a higher amount to absorb and afterward your Product needs to be Brushed out. If you have a modern approach wear you just want to extend the washing cycle about 1 day or use it as a styling product you need much less starch to get that effect.

    you can look at the homepage of Aggrana ( AGRANA International | Frucht, Stärke, Zucker | AGRANA ) they have various formulations for both wear you can get an idea of how much starch is needed to get the effect you want to have.

    I will add to @gordof comments. Rice starch is not abrasive or any way harmful, nor will it wet out and be gummy like rice flour will. No need to certify as it already certified by the supplier. It will adsorb sebum and organic dusts very effectively and leave a silky soft sensorial on your hair, making it ideal as a dry shampoo base. As Gordof stated it will mattify too so if shine is your jam, you’ll want to look elsewhere. Agrana is a fine Italian source, but if you are in North America you’ll find it easier to obtain Activederm RP from 3V Sigma USA.
