Formulation Guideline for Hair Bleach Powder

Question

Hello,

Do you have a hair bleach powder formulation guideline? If yes, can I have it?

Thank you.

Answer 1

Hair bleach powder is a complex mixture of oxidizing agents, alkalizers, and conditioners designed to lift natural hair pigment. Below is a general formulation guideline for a high-performance hair bleach powder.

Core Components of Hair Bleach Powder

Oxidizing Agents (Persulfates): These are the primary active ingredients that release oxygen to break down melanin. A combination of different persulfates is often used to balance the speed and intensity of the lift.
- Potassium Persulfate: The most common booster for high-lift results.
- Ammonium Persulfate: Provides rapid lifting action but can have a stronger odor.
- Sodium Persulfate: Often used as a secondary booster.
Alkalizing Agents: These raise the pH to swell the hair cuticle, allowing the oxidizers to penetrate. Common examples include Sodium Silicate, Sodium Metasilicate, or Magnesium Carbonate.
Thickeners & Stabilizers: These ensure the mixture has a creamy consistency when mixed with a developer (Hydrogen Peroxide). Examples include Xanthan Gum, Guar Gum, or Cellulose derivatives.
Chelating Agents: Such as Disodium EDTA, to neutralize metal ions in the hair that could cause uneven results or damage.
Color Correctors: Pigments like Ultramarine Blue or Violet are added to neutralize unwanted yellow or orange tones during the bleaching process.

Sample Formulation Guideline (Powder Base)

Ingredient Type	Ingredient Name	Usage Rate (%)
Oxidizer	Potassium Persulfate	30.0 - 50.0%
Oxidizer	Ammonium Persulfate	10.0 - 20.0%
Oxidizer	Sodium Persulfate	5.0 - 15.0%
Alkalizer	Sodium Silicate / Metasilicate	15.0 - 25.0%
Filler/Alkalizer	Magnesium Carbonate	5.0 - 10.0%
Thickener	Guar Hydroxypropyltrimonium Chloride	1.0 - 3.0%
Chelating Agent	Disodium EDTA	0.2 - 0.5%
Pigment	Ultramarine Blue / Violet	0.1 - 1.0%

Preparation and Usage

Mixing: The powder must be mixed with a Cream Developer (Hydrogen Peroxide) in a ratio typically ranging from 1:1.5 to 1:2 (Powder:Developer).
Safety: Persulfates are strong oxidizers. Formulations are often made "dust-free" by adding a small amount of mineral oil or isopropyl myristate (approx. 1-3%) to prevent the powder from becoming airborne during mixing.
Testing: Always perform a strand test and a patch test before full application.

Important Safety Note

Hair bleaching involves strong chemical reactions. Ensure the manufacturing environment is well-ventilated and use appropriate personal protective equipment (PPE) such as masks and gloves when handling raw persulfate powders.
