คำถาม
- Could you provide a simple hand cream formulation example?
- If making a hand cream containing the disinfectant Chloroxylenol (water-based) at 1.5%, is this possible?
- Is Chloroxylenol safe for daily use in a leave-on hand cream? For example, when handling food or touching the face and eyes.

Simple Hand Cream Formulation Example
Here is a basic example of a simple hand cream formulation using Easy Cream Maker™:
- Water Phase:
- Water: 70-80%
- Glycerin: 3-5% (Humectant)
- Preservative: ~1% (Use a broad-spectrum cosmetic preservative according to supplier recommendations)
- Oil Phase:
- Light Oil (e.g., Fractionated Coconut Oil): 5-10%
- Easy Cream Maker™: 2-3% (Mix into oil phase)
- Optional:
- Fragrance: 0.1-0.5%
- Other desired active ingredients
Instructions:
- Combine the water phase ingredients and heat if necessary (Easy Cream Maker™ doesn't require heat, but other ingredients might).
- Combine the oil phase ingredients, mixing the Easy Cream Maker™ into the oil.
- Slowly add the oil phase to the water phase while stirring continuously until a cream forms. Avoid excessive high-speed mixing.
- Add optional ingredients like fragrance after the cream has formed and cooled slightly.
- Ensure pH is within the recommended range for the preservative and cream maker.
This is a basic example. Formulation requires careful measurement, mixing, and stability testing. You could also use other cream makers like Soft Cream Maker™, which requires heat but can handle higher oil percentages.
Chloroxylenol (PCMX) in Hand Cream
Regarding the use of Chloroxylenol (PCMX) in hand cream:
- Concentration: Using 1.5% of the Chloroxylenol (PCMX) (15% Water Soluble) solution is equivalent to using 0.225% pure Chloroxylenol. According to product information, the FDA allows Chloroxylenol powder (100% pure) to be used as a preservative in cosmetic formulas at a maximum rate not exceeding 0.5%. Therefore, 1.5% of the 15% water-soluble solution is within this limit for use as a preservative.
- Safety for Leave-on Use: While 0.225% pure PCMX is within the preservative limit, using Chloroxylenol at concentrations intended for disinfection (which are typically much higher than 0.5% pure PCMX, like the 4.8% in Dettol) in a leave-on hand cream is generally not recommended. Product information indicates that if you wish to use it at a higher rate than 0.5%, it should be used in cleaning products or disinfectant products only. Applying a hand cream containing Chloroxylenol at disinfection levels and then touching food, face, or eyes could pose risks due to potential irritation or ingestion. For a leave-on product like hand cream, it is safer to use PCMX only within the allowed preservative limit (up to 0.5% pure PCMX) and not rely on it for significant disinfection efficacy, or consider alternative disinfectants/antiseptics more suitable for leave-on skin applications if disinfection is the primary goal.
