Ingredient Solubility Questions

Here is the solubility information for the ingredients you asked about:

• Wild Yam Extract (Diosgenin 95%) and Cerasoft (Synthetic Ceramide): Wild Yam Extract is soluble in highly polar oil. Cerasoft is an oil-soluble emollient. Based on their solubility properties, Wild Yam Extract should be able to dissolve in Cerasoft.
• Phytosphingosine and Ethoxydiglycol: Phytosphingosine is soluble in organic solvents and glycols. Ethoxydiglycol is a glycol solvent and carrier. Therefore, Ethoxydiglycol at 1% should be able to dissolve Phytosphingosine at 0.1%.
• Centella Asiatica Extract TECA and Ethoxydiglycol: Centella Asiatica Extract TECA is soluble in Propylene Glycol and Butylene Glycol. Ethoxydiglycol is a glycol solvent and may be able to dissolve TECA, but the product description does not specify the required ratio for dissolution in Ethoxydiglycol.
• Centella Asiatica Extract TECA and Ultra Solve HPS: Centella Asiatica Extract TECA is not soluble in oil or water, but is soluble in glycols like Propylene Glycol and Butylene Glycol. Ultra Solve is a solubilizer primarily used for dissolving oils into water. Based on the product descriptions, Ultra Solve is not suitable for dissolving Centella Asiatica Extract TECA.
