Formulation Feedback

Regarding your proposed formulations for silver nano pet shampoo and multi-purpose spray, I can provide information about the ingredients found in our database. However, please note that providing specific formulation advice, validating percentages, or recommending precise pH values requires expert formulation knowledge, laboratory testing, and consideration of safety and regulatory standards, especially for products intended for pets or for disinfection.

Here is some information about the ingredients you listed that are available in our database:

Silver Nano Pet Shampoo Formulation

Ingredients found in the database:

• Deionized Water
• Coco Glucoside
• PEG-80 Sorbitan Laurate (equivalent to Tween 28)
• Glycerin
• Phenoxyethanol

Colloidal Silver was not found in our database.

Regarding your questions:

• Cleansing efficacy of Coco Glucoside: Coco Glucoside is a gentle non-ionic surfactant and acts as a detergent. However, the product description indicates it does not provide significant foam on its own and is often used in combination with other foaming detergents for better performance. The recommended usage rate is 5-25%, with 5% suggested for gentle skin. Whether 5-25% is sufficient for your specific pet shampoo application would require testing.
• Shampoo pH: The description for Coco Glucoside notes that it has an alkaline pH (around 11.5) and requires pH adjustment. For sensitive skin, a pH range of 5-6.5 is suggested using acids like Citric Acid or Lactic Acid. While you asked about a pH of 8-9 for pet shampoo, the optimal pH for pet products can vary depending on the animal and specific product type. Determining the appropriate and safe pH for a pet shampoo requires expert knowledge and testing.

Other ingredients:

• PEG-80 Sorbitan Laurate is described as a gentle surfactant and foam-booster.
• Glycerin is a humectant, solvent, and emollient.
• Phenoxyethanol is a preservative effective against bacteria but less so against fungi. Its recommended usage rate is 0.5-1.0%. It is effective in a pH range of 2-9.

Silver Nano Multi-Purpose Spray Formulation

Ingredients found in the database:

• Deionized Water
• Hydrogen Peroxide Gel
• Glycerin
• Sodium Bicarbonate
• Phenoxyethanol

Colloidal Silver was not found in our database.

Information on these ingredients:

• Hydrogen Peroxide Gel is available as a 15% stabilized gel.
• Glycerin is a humectant and emollient.
• Sodium Bicarbonate is used to increase alkalinity (raise pH). It has limited solubility in water (up to about 9%).
• Phenoxyethanol is a preservative effective against bacteria but less so against fungi, with a recommended usage rate of 0.5-1.0% and effective pH range of 2-9.

Please remember that formulating safe and effective products, especially those involving active ingredients like silver nano (if sourced elsewhere) or hydrogen peroxide, requires careful consideration of ingredient compatibility, stability, efficacy testing, and safety for the intended use (pets or general disinfection). Consulting with a formulation chemist or regulatory expert is highly recommended.
