Carbomer Carbopol 940 powder

Description

Carbomer Carbopol® 940 polymer is a white powder, crosslinked polyacrylic acid polymer. It is an extremely efficient rheology modifier (a highly efficient thickener) capable of providing high viscosity and forms sparkling clear gels or hydro-alcoholic gels and creams.

Carbomer is a white fluffy powder which when neutralised creates clear gels and brings consistency and flow enhancement to products. Used in creams, lotions and shower gels imparts a silky feel.

Carbomer is the key ingredient in hand sanitisers as it creates the gel that thickens the alcohol and water mix

Carbomer not only thickens a product, but will bring stability and texture enhancement. By changing the usage level, you can create a stable free flowing product to a very stiff hair gel.

Carbomer always has to be neutralised to work and this is most commonly done with Sodium hydroxide. Once neutralised correctly, Sodium hydroxide will not be present in your final formulation.

Primary Functions of Carbomer Carbopol ® 940 Powder:

Cosmetic Benefits of Carbomer Carbopol ® 940:

-High viscosity builder and stabilizer
-Light skin feel
-Provides clarity and a high -suspending ability in hair gels
-Short flow rheology characteristics

Compatibility: Because Carbomer 940 is anionic viscosity is affected by cations (especially sodium) and you will need to neutralize prior to the addition of other phase ingredients to minimize the impact, otherwise neutralize final formulation.

Neutralization: solution will not fully thicken until neutralized (pH raised). We recommend using Tetrasodium EDTA or Suttocide A to neutralize the Carbomer. Test the pH of the formulation with your pH meter. Then add neutralizing agent until a pH of 5.5-7 (depending on preference) is achieved.

Other neutralizing ingredients (in ratio):

(A). TEA (Triethanolamine)99%: Begin with 99% pure Triethanolamine, and create a 50%solution with distilled water. Of this solution, you would generally use 4 parts TEA to every 1 part Carbomer 940.

(B). NaOH (Sodium Hydroxide): Begin with Caustic Soda Pearls and make a 25% solution with distilled water. Of this solution, you would generally use 2 parts NaOH to every 1 part Carbomer 940.

(C). KOH (Potassium Hydroxide): Begin with Potassium Hydroxide and make a 25%solution with distilled water. Of this solution, you would generally use 2 parts KOH to every 1 part Carbomer 940.

(D). DOW Versene 100 (Tetrasodium EDTA): Generally, you would add 1 part TetrasodiumEDTA to 1 part Carbomer 940.

(E) Suttocide A: Generally, you would use slightly more Suttocide A than Carbomer 940, for instance 0.9% Carbomer 940 and 1% Suttocide A. Suttocide A will preserve the formulation and neutralize the Carbomer. This is the exact ratio we typically use, and find that we can achieve adequate suspension, viscosity, and preservation with these exact usage rates while maintaining crystal clear solutions.

Solubility: Water Soluble

Mixing Method: Water Soluble, see below:

1. Hydrating the Carbomer: As with gums, Carbomer 940 should be put into a dry container to which the amount of room temperature distilled/deionized water, in your formula, will be added. Carbomer 940 should then be allowed to swell/hydrate. The pH of the Carbomer gel will be about 3.3 prior to neutralization.

2. When the Carbomer is fully hydrated, and IF the formula does not contain ingredients that may have compatibility issues with Carbomer, then incorporate the remaining aqueous ingredients and heat if necessary. Incorporate other phases if applicable.

3. Compatibility: Carbomer 940 is anionic, and therefore may experience compatibility problems with any cationic material. Sodium (salt) may have a negative effect on the viscosity of Carbomer 940 products. To minimize these negative effects, neutralize(see Above) Carbomer gel before adding in the other phases/ingredients.

4. Neutralization: Preferably, neutralization would take place at the end of formulation. This would be the instruction in all cases. This is preferable because the Carbomer will not fully thicken the product until you raise the pH. This makes the formulation easier to work with.

Melting Temperature:, Avoid heat above 50°C (122°F)

Origin: U.S.A

Applications:
Skin Gel
Hair Gel
Shower Gel
Shampoo
Face Wash
Moisture Lotion
Moisture Cream

Precautions:
Carbomer is especially formulated for the demands of Cosmetic production and is not intended for internal use. Care should be taken during the neutralisation process to avoid contact with Sodium hydroxide on the skin. Using KOH or NaOH to neutralize Carbomer 940 may affect the clarity of the formulation in some cases.

In order to keep consistancy, sheer (the amount of mixing) of Carbomer based products should be kept the same as viscosity of Carbomer based gels decreases the more Sheer that is given to the final product.

Packaging: Our powders are packed in water proof ziplock pouches to avoid spillage.

Recommended Storage: Our powders should be stored in cool temperatures away from direct sunlight and moisture in an airtight container.
