Question
Regarding my proposed water-based cosmetic formula (listing ingredients and percentages), what will the texture be like (specifically aiming for a watery essence/toner), is a preservative necessary, and what modifications or development work might be required for manufacturing?
Answer
Subject: Review of Your Cosmetic Formula
Thank you for sharing your formula for review. Based on the ingredients and percentages provided, here is an assessment:
1. Texture (Essence/Watery Lotion):
- Based on the high water content (Water + Aloe Vera Gel Lite) and the low concentration of active ingredients without added thickeners, the texture of this formula is highly likely to be very fluid, similar to a watery essence or toner ("น้ำตบ").
- This texture seems well-suited for your goal of creating a light, single-step product for users who prefer minimal layers.
- No specific recommendations are needed to achieve this texture, as the current composition naturally lends itself to a watery feel.
2. Need for Preservative:
- Yes, a preservative system is absolutely necessary for this formula.
- Since the formula is predominantly water-based, it is highly susceptible to microbial contamination (bacteria, mold, yeast). A suitable preservative system is required to ensure the product's safety, stability, and shelf life.
3. Modifications for Production:
- Yes, it is highly likely that a manufacturing company would propose modifications and require further development work before mass production.
- While your formula is a good starting point, a production-ready formula needs to undergo rigorous testing and optimization. Potential areas for modification and development include:
- Adding a suitable preservative system and conducting challenge testing to confirm efficacy.
- Checking and adjusting the pH for optimal stability, ingredient performance, and skin compatibility.
- Performing stability testing under various conditions (temperature, time) to ensure the product remains consistent.
- Optimizing sensory properties (e.g., feel on skin, clarity, potential tackiness from Rhamnose).
- Ensuring the long-term stability and dispersion of ingredients like the Ceramide Complex.
- Considering manufacturing scale-up feasibility and regulatory compliance.
- Therefore, a manufacturing partner would typically take this base formula and conduct the necessary development work to turn it into a stable, safe, and marketable product.
