Preservative PHENONIP ME 30 g

Phenonip ME preservative - use in cosmetics

Phenonip ME paraben preservative is a broad-spectrum antimicrobial additive consisting of a synergistic mixture of parahydroxybenzoic acid esters (parabens) in phenoxyethanol, intended as a preservative for use in a wide range of cosmetic and hygiene products.

An analogue of this preservative may be another paraben preservative Phenonip XB, which is a mixture of phenoxyethanol, methylparaben, ethylparaben and propylparaben.

Component characterisation and specifics of use

INCI: Phenoxyethanol, Methylparaben, Ethylparaben

Dosage: 0.25 - 1.2 %. Approximate recommendations for different types of cosmetics:

• 0.25 - 0.8 % in shampoos and shower gels
• 0.6 - 1.0 % in formulas containing proteins (hydrolysates, peptides)
• 0.6 - 1.2 % in emulsion systems.

The exact injection dosage for your formula must be selected independently. The shelf life of the product can only be established by laboratory analysis. 

Solubility: up to 0.7 % of the preservative is soluble in water, also soluble in ethanol and water/ethanol mixtures. In most cases
heating water to 60 - 70 C before introducing Phenonip ME will dissolve the required amount. If aqueous systems cannot be heated, Phenonip ME is added by first preparing a concentrate in a suitable solvent such as pentylene glycol. To introduce the preservative into emulsions, you can add it to the fatty phase before emulsification, or you can introduce it into the finished warm emulsion. When making detergents, you can add the preservative to the surfactant before adding water. Works over a wide pH range of 3.0 - 8.0.

Storage: in a dark, dry place, in a tightly closed container at a temperature of 5 to 25 C. The product may crystallise at low temperatures. In these cases it should be allowed to thaw at room temperature and mixed before use.

Efficacy of Phenonip ME Paraben Preservative

Phenonip ME provides resistance to Gram-positive and Gram-negative bacteria, moulds and yeasts.
The preservative remains active in the presence of most cosmetic ingredients.

Phenonip ME protects most types of personal care products from microbial contamination. As with other
preservatives, the correct concentration depends on several factors, including the chemical and physical characteristics of the product, the ability of the product to support microbial growth, and the ability of the product to protect against microbial contamination.
characteristics of the product, the ability of the product to support microbial growth, and the likelihood of re-infection during use.
application.

Practice has shown that at concentrations between 0.25% and 1.2%, Phenonip ME is capable of preserving cosmetic and hygienic
products. As a rule, higher concentrations are only necessary in the formulation of products which, by their nature, are particularly difficult to preserve.

Shampoos and bath foams are preserved when Phenonip ME is added at concentrations between 0.25 % and 0.8 %. If the product has a high protein content, the required concentration may be higher: 0.6 % to 1 %. Other surfactant-based products, e.g.: liquid dishwashing detergents, are generally retained when Phenonip ME is added at a concentration of 0.2 % to 0.6 %.

Effective protection of oil/water and water/oil emulsion systems can be achieved by adding Phenonip ME in concentrations from 0.6 % to 1 %. Phenonip ME can also be used to preserve emulsions based on non-ionic surfactants. However
However, higher concentrations of 0.8 % to 1.2 % may be required.
 

Antimicrobial activity of the preservative

Phenonip ME demonstrates microbiostatic activity against a wide range of bacteria, yeasts and moulds. The following table shows the minimum inhibitory concentration (MIC) Phenonip ME is active against the different groups of microorganisms represented.
 

What to dissolve Phenonip in and how to introduce it into a cosmetic formulation (examples of solvents for paraben preservative)

• Water: about 0.7 %
• Ethanol: soluble
• Ethanol/Water (50/50): > 95 %
• Isopropanol: miscible
• Acetone: miscible
• Propylene glycol: miscible
• Liquid paraffin: < 0.1 %
• Glycerol: approx. 8 %
• Sodium laureth sulphate (28 %): blended.
   

To introduce a preservative into cosmetics, follow the following recommendations for solubility and application procedure:

• Aqueous phase: introduced until the solubility limit is reached.
• Low water content formulations: heating water to 60-70°C before adding Phenonip ME to it will, in many cases, allow the required amount of preservative to dissolve.
• Aqueous systems that cannot be heated: the preservative can be introduced by being pre-diluted in a suitable solvent, e.g. pentylene glycol, propylene glycol, and stirred well into the water, reaching the water solubility limit.
• Emulsion systems: rapidly dissolves in the oil phase immediately before emulsification; in practice, the amount of Phenonip ME is often divided between the oil and aqueous phases during their preparation.
• The method of introducing Phenonip ME at the final stage of emulsification (during the cooling phase) is widespread.
• In cosmetics containing surfactants, Phenonip can be added to the surfactant before the addition of the aqueous phase.

Phenonip ME can be used in cosmetic products at a maximum concentration of 1.29 %. There are no other restrictions according to
Annex VI, 76/768/EEC (Europe). The use of Phenonip ME is authorised in Japan at a concentration of up to 1.29 %. There are no other restrictions. Phenonip ME is authorised in the USA.
