ถามโดย: kookkaiiip เมื่อ: April 09, 2020 ประเภทผลิตภัณฑ์: เครื่องสำอาง

คำถาม

  1. Could you provide a simple hand cream formulation example?
  2. If making a hand cream containing the disinfectant Chloroxylenol (water-based) at 1.5%, is this possible?
  3. 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:

  1. Combine the water phase ingredients and heat if necessary (Easy Cream Maker™ doesn't require heat, but other ingredients might).
  2. Combine the oil phase ingredients, mixing the Easy Cream Maker™ into the oil.
  3. Slowly add the oil phase to the water phase while stirring continuously until a cream forms. Avoid excessive high-speed mixing.
  4. Add optional ingredients like fragrance after the cream has formed and cooled slightly.
  5. 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:

  1. 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.
  2. 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.
