Question

Please recommend a formulation for a 30ml Dry Shampoo. The ingredients are as follows:

  • Ethyl Alcohol 99.9%
  • Cyclomethicone
  • Panthenol
  • PEG-40 Hydrogenated Castor Oil
  • Dry Shampoo Powder (Rice-based)
  • Lavender EO
  • Geranium EO
  • Distilled/RO Water

I would like to know the required amount/percentage for each ingredient in the mixture.

Answer

For a 30ml Dry Shampoo spray formulation using your selected ingredients, here is a recommended formula. This formula is designed as a "Liquid-to-Powder" spray that evaporates quickly, leaving the starch to absorb oil while providing hair nourishment and a pleasant scent.

Dry Shampoo Spray Formula (Total 30g / approx. 30ml)

Ingredient Percentage (%) Amount for 30ml (g)
1. Ethyl Alcohol (99.9%) 70.0% 21.00 g
2. Dry Shampoo Powder (Rice-based) 8.0% 2.40 g
3. Cyclomethicone 3.0% 0.90 g
4. Panthenol (Vitamin B5) 0.5% 0.15 g
5. PEG-40 Hydrogenated Castor Oil 1.5% 0.45 g
6. Lavender Essential Oil 0.3% 0.09 g (approx. 2-3 drops)
7. Geranium Essential Oil 0.2% 0.06 g (approx. 1-2 drops)
8. Distilled Water / RO Water 16.5% 4.95 g
Total 100% 30.00 g

Mixing Instructions

  1. Prepare the Scent Phase: Mix the PEG-40 Hydrogenated Castor Oil with the Lavender Essential Oil and Geranium Essential Oil. Stir until the mixture is clear. This helps the oils disperse in the water/alcohol base.
  2. Prepare the Alcohol Phase: Mix the Cyclomethicone into the Ethyl Alcohol.
  3. Prepare the Water Phase: Dissolve the Panthenol powder in the Distilled Water until completely clear.
  4. Combine Liquids: Slowly add the Water Phase and the Scent Phase into the Alcohol Phase. Stir well.
  5. Add Powder: Finally, add the Dry Shampoo Powder. The powder will not dissolve but will disperse in the liquid.
  6. Packaging: Pour into a spray bottle.

Usage Notes

  • Shake Well Before Use: Since the Dry Shampoo Powder is a solid particle, it will settle at the bottom. You must shake the bottle vigorously before every use to ensure the powder is evenly distributed.
  • Spray Technique: Spray onto the roots of the hair from a distance of about 15-20 cm. Let it dry for a few seconds, then massage with your fingertips or brush through.
  • Clogging: Use a spray head suitable for suspensions to prevent the powder from clogging the nozzle. Clean the nozzle regularly with warm water if needed.

Question:

Please recommend a formulation for a 30ml Dry Shampoo spray. If Glycerin is added as an additional ingredient, how should the percentages of each component be adjusted?

The original ingredients are as follows:

  • Ethyl Alcohol 99.9%
  • Cyclomethicone
  • Panthenol
  • PEG-40 Hydrogenated Castor Oil
  • Dry Shampoo Powder (Rice-based)
  • Lavender EO
  • Geranium EO
  • Distilled/RO Water
Answer:

For a 30ml Dry Shampoo spray formulation including Glycerin, the proportions are adjusted by reducing the water content to accommodate the humectant. Glycerin will help moisturize the scalp and reduce potential irritation from the high alcohol content.

Total 100% 30.00 g

Mixing Instructions

  1. Prepare the Scent Phase: Mix the PEG-40 Hydrogenated Castor Oil with the Lavender Essential Oil and Rose Geranium Essential Oil. Stir until the mixture is clear. This helps the oils disperse in the water/alcohol base.
  2. Prepare the Alcohol Phase: Mix the Cyclomethicone into the Ethyl Alcohol.
  3. Prepare the Water Phase: Dissolve the Glycerin and D-Panthenol in the Distilled Water until completely clear.
  4. Combine Liquids: Slowly add the Water Phase and the Scent Phase into the Alcohol Phase. Stir well.
  5. Add Powder: Finally, add the Dry Shampoo Powder. The powder will not dissolve but will disperse in the liquid.
  6. Packaging: Pour into a spray bottle.

Usage Notes

  • Shake Well Before Use: Since the Dry Shampoo Powder is a solid particle, it will settle at the bottom. You must shake the bottle vigorously before every use to ensure the powder is evenly distributed.
  • Glycerin Content: We recommend keeping Glycerin at 2% to provide moisture without making the hair feel sticky.
  • Clogging: Use a spray head suitable for suspensions to prevent the powder from clogging the nozzle. Clean the nozzle regularly with warm water if needed.
