Solubility of Zinc Ricinoleate and Water-Soluble Alternatives for Odor Absorption
Question
I was trying to dissolve solid Zinc Ricinoleate in water, but it did not dissolve. I was previously informed by customer service that it could be dissolved in water. Can you confirm if solid Zinc Ricinoleate is water-soluble or oil-soluble/dispersible?
If I need a water-based formulation for an odor absorbent, what are the recommended ingredients or formulations, including how to use Zinc Ricinoleate (30% Solution) or an alternative like Anti-Sweat™ (Aluminum Chlorohydrate)?
Answer
Understanding Zinc Ricinoleate Solubility
Based on the information from our staff and product details, solid Zinc Ricinoleate does not dissolve in water. Your observation that it did not dissolve in water is correct.
Solid Zinc Ricinoleate is designed to be dispersed in the oil phase of a formulation. For it to work effectively, the powder needs to be well-dispersed within the oil phase of your product.
Alternative: Liquid Zinc Ricinoleate (30% Solution)
We offer a product called Zinc Ricinoleate (30% Solution), which is a liquid form that is dispersible in water. This might be suitable if you require a liquid ingredient for your formulation. It is stable in formulas with a pH range of 7.5-11 and can be used at a rate of 1-4%.
If you aim for a clear liquid formula using Zinc Ricinoleate (30% Solution), you can consider a composition like this:
- Zinc Ricinoleate (30% Solution): 1-4%
- Ultra Solve: 3-7%
- Propylene Glycol or Butylene Glycol or Ethyl Alcohol: 5-20%
- Disodium EDTA (for pH < 8) or Tetrasodium EDTA (for pH > 8): 0.1%
- Water: Balance to 100%
Alternative Water-Soluble Odor Absorber: Anti-Sweat™ (Aluminum Chlorohydrate)
If you specifically need an odor absorbent that dissolves directly in water, our staff recommended considering other options like Anti-Sweat™ (Aluminum Chlorohydrate). This ingredient is a powder that can be dissolved in water (up to 50% concentration, meaning 1g dissolves in 2g of water) and is suitable for water-based antiperspirant/deodorant formulas.
To Provide More Specific Advice
To give you the best recommendation for incorporating an odor absorbent into your product, please let us know the specific type of formula or product you are developing (e.g., spray, roll-on, cream, powder). Knowing your intended product will help us suggest the most suitable ingredient and method of incorporation.
