Suitability of Big C Drinking Water for Cosmetic Production (Low TDS)
Question
Regarding the previous discussion about using water with low TDS (like RO or distilled water) for cosmetic production, the staff mentioned that Big C drinking water is also suitable. Could you please confirm if น้ำดื่มบิ๊กซี can indeed be used for cosmetic production, considering the requirement for low TDS water?
Answer
Based on the forum discussion, water used in cosmetics should ideally have a low level of Total Dissolved Solids (TDS). A lower TDS indicates higher purity, which is important for cosmetic formulation.
Key points from the discussion:
- Water with low TDS is preferred.
- A specific 7-Eleven brand (green label/cap, RO, UV, Ozone treated) was mentioned as having a very low TDS, comparable to distilled water.
- Big C water was tested by the staff and found suitable for cosmetic production.
Therefore, water with low TDS, such as distilled water, RO water, or certain bottled water brands confirmed to have low TDS (like the 7-Eleven green label or Big C water mentioned), can be used for mixing cosmetics.
