Study Notes
Formulation Overview
- The formulation consists of several phases: Phase B is heated to 80°C, and Phase C is added gradually at 50°C.
- Major ingredients include stearic acid, cetyl alcohol, and various surfactants and oils.
Ingredient Details
- Stearic Acid: Used as a thickener and emollient.
- Cetyl Alcohol: An emulsifier that helps stabilize the cream.
- Montanov 68 M: A blend of cetearyl alcohol and cetearyl glucoside, serving as an emulsifying agent.
- Argan Oil: Adds moisturizing properties.
- Vitamin E (Tocopheryl Acetate): Acts as an antioxidant.
- Euxyl K9002: A preservative system to enhance product shelf life.
- Sodium Chloride: Used to adjust viscosity.
Appearance and Stability
- The end product has a milky white, semi-solid cream appearance with a pH of 6.5.
- Stability tests indicate the product remains stable for 3 weeks at room temperature and at accelerated temperature control (40°C).
Adjustments and Specifications
- pH and viscosity adjustments can be made with sodium chloride and citric acid.
- Viscosity measured at 1060 Cps using a Brookfield Viscometer indicates a suitable texture for application.
Hair Serum Details
- The formulation includes active ingredients like Aquaxyl, which promotes hydration, and Essensil sweet silk, which enhances smoothness.
- The hair serum targets dry and dull hair, offering nourishment and conditioning.
- A milky white semi-solid cream at a pH of 5.6 is the desired outcome for this product as well.
Fragrance and Other Additives
- Fragrance compositions include components like vanilla and coconut water for a pleasant scent.
- Various suppliers such as Yasham and Gogia are noted for the sourcing of certain ingredients.
Final Notes
- While multiple raw materials contribute to the overall formulation, the combination of surfactants, oils, and emulsifiers ensures both efficacy and user experience.
- The overall stability and performance under controlled conditions demonstrate the effectiveness of the formulation strategy.
