Color-Protecting Conditioner

General Recipe:

1. Cationic Surfactants (5-10%): Such as Behentrimonium Methosulfate, Cetrimonium Chloride, or Stearamidopropyl Dimethylamine. These ingredients work as conditioning agents and help to smooth the hair cuticle.

2. Emollients (3-10%): Oils such as argan oil, avocado oil, or jojoba oil can be used. These oils offer hydration and shine to the hair.

3. UV Filters (2-5%): Ingredients like Ethylhexyl Methoxycinnamate, Benzophenone-4 or -3, Butyl Methoxydibenzoylmethane help to protect the hair color from UV damage.

4. Antioxidants (0.1-1%): Such as Vitamin E (Tocopherol) to provide protection against oxidative damage.

5. Protein (0.5-5%): Hydrolyzed wheat protein or silk protein can be included to strengthen the hair and improve its texture.

6. Humectants (1-5%): Ingredients like Glycerin or Panthenol help to attract and hold moisture in the hair.

7. Preservatives (0.5-1%): Phenoxyethanol, Sodium Benzoate, or Potassium Sorbate to prevent microbial growth.

8. Thickeners (0.2-1%): Xanthan Gum or Hydroxyethylcellulose can be used to increase the viscosity of the conditioner.

9. Fragrance/ Essential Oils (0.2-1%): For scent and additional beneficial properties for the hair and scalp.

10. pH Adjusters (0.1-0.5%): Citric Acid or Lactic Acid to maintain the product at a hair-friendly pH, generally slightly acidic to help seal the hair cuticle.

11. Deionized Water (to 100%): The remaining percentage is typically water.
