Formulating Temporary Grey Hair Spray (Pump) from Aerosol Formula

Hello,

Based on the ingredient list of the DIPSO product you provided, which is an aerosol spray, you can adapt the formula for a regular pump spray by omitting Dimethyl ether.

The key ingredients needed for a temporary grey hair spray formula (non-aerosol), based on the original ingredients and staff advice, are as follows:

Basic Formula (for Pump Spray):

• Ethyl Alcohol: 60-80% (Acts as a solvent, helps with fast drying, and serves as a preservative if used at over 20%)
• Water: 0-20% (Optional, can help disperse ingredients, but may slow drying time)
• Easy Hair Styler (8 Hr.) (Film Former): 2-5% (Forms a film on the hair, helping the color adhere, replaces VP/VA Copolymer)
• Silicones (Phenyl Trimethicone + PEG-12 Dimethicone): 2-5% total (Provide shine and smoothness as you desired)
• Perfume: 0.1-1% (For adding your desired fragrance)
• Colorants: 1-10% (Total pigment load, adjust based on desired color intensity)

Selecting and Mixing Colorants:

• For Black: Use CI77499 (Iron Oxides Black) at 1-10% of the total formula.
• For Dark Brown: Use a blend of several pigments based on the ingredients you listed for the dark brown version:
  • CI77499 (Iron Oxides Black): Use the highest percentage (e.g., 3-7%) for the dark base color.
  • CI77491 (Iron Oxides Red): Use a smaller percentage (e.g., 0.5-2%) to add red/brown tones.
  • Titanium Dioxide: Use a very small percentage (e.g., 0.1-0.5%) to adjust lightness and opacity.
  • Mica: Use a small percentage (e.g., 0.5-2%) to adjust tone and sheen.
  • Recommendation: Achieving the desired dark brown shade will require experimentation to adjust the ratio of these four pigments (CI77499, CI77491, Titanium Dioxide, Mica). The total pigment load should be within the 1-10% range.

Basic Mixing Instructions:

1. Combine Ethyl Alcohol and Water (if using).
2. Gradually add the pigments to the liquid mixture. Stir or use a high-shear mixer briefly to help disperse the pigments well (pigments may settle, so shake the bottle well before each use).
3. Add Easy Hair Styler, Phenyl Trimethicone, PEG-12 Dimethicone, and Perfume.
4. Mix thoroughly until homogeneous.
5. Pour into a pump spray bottle.

Important Notes:

• This formula is a starting guideline. The optimal percentages may need to be adjusted based on your testing to achieve the desired texture, color, and performance.
• Increasing the amount of silicones (Phenyl Trimethicone, PEG-12 Dimethicone) may help increase smoothness and shine, but should stay within the recommended range to avoid affecting other properties like drying time.
• If using Ethyl Alcohol at over 20%, a preservative is not necessary.
