Preservative 12
Preservative 12
Preservative for Cosmetics-Industry |
Product-Description
Preservative No. 12 consists of a combination of Methyl-, Ethyl- and Propylparaben in Phenoxyethanol. It does not contain formaldehyde or formaldehyde-releasing substances and conforms to the regulations of the EC cosmetics law.
By the choice of parabenes as the product-base it has to be regarded, that these substances will be desactivated by nonionic or highly ethoxylated surfactants. This fact can make it necessary to adapt the product-formula to the preserving system.
Ranges of Application
Rinse-off-Cosmetics | Preservative No. 12 has proven to be an effective preserving system for rinse-off-products like shampoos, shower-gels, foam-baths etc., as these products generally have slightly acidic pH, which is a necessary condition for a safe use. |
Care-Products | Due to its good skin-compatibility Preservative No. 12 is suitable for high-quality care-cosmetics like creams, emulsions, lotions and gels. On account of its good dispensability it can be used in O/W-emulsions as well as in W/O-emulsions. |
Dosage and Processing
Preservative No. 12 is used in cosmetic products in concentrations of 0.3 % to 1.0 %. When preserving simple surfactant-products sometimes dosages of 0.2 % are sufficient.
For the determination of the optimum dosage we recommend a test-preservation, as the efficacy of this preservative is highly influenced by the product-matrix. On demand, our microbiological laboratory will give you the appropriate support.
When worked into products at ambient temperature Preservative No. 12 may be added at any phase of production. If used in emulsion-products Preservative No. 12 is added to the aqueous phase. Heating processes up to 80 °C will be well tolerated.
Especially in aqueous products with low contents of emulsifiers intensive stirring is recommended, to achieve a quantitative solution of the active ingredient.
