Germaben II

Germaben II

*Preservatives are sold by weight not volume.

Germaben II is an ideal preservative system for shampoos, hair conditioners and emulsion products. Germaben II minimizes the problems associated with incorporating solid Parabens. It dissolves completely in cosmetic formulations at a 1.0% concentration over a wide pH range. It can be conveniently incorporated into cold processed shampoos and into creams and lotions during their manufacture. The preferred method of addition of Germaben II is to add it slowly to the product with good stirring just prior to the addition of the fragrance. Germaben II has also been successfully used to preserve troublesome formulations containing nonionic surfactants, proteins, soluble collagen, aloe vera extracts and herbal extracts. The broad spectrum of antimicrobial activity obtained by the combination of Germall II with methylparaben and propylparaben provides the preservation protection necessary for sophisticated personal care products.

Germaben II is recommended to be used at a level of up to 1.0%. This level provides to the product: 0.30% Germall II, 0.11% methylparaben, 0.03% propylparaben and 0.56% propylene glycol. Shampoos and liquid soaps generally require less than 1.0% Germaben II. Although Germaben II provides excellent antimicrobial preservation, every developed or modified product should be challenge tested to assure preservative efficacy.

Germaben II is a clear viscous liquid with a characteristic mild odor. It is readily soluble at a level of 1.0% in both aqueous solutions and oil/water emulsions. Germaben II is a convenient, ready to-use complete antimicrobial preservative system with a broad spectrum of activity. The solubilized combination of Germaben II with methylparaben and propylparaben is effective against Gram-positive and Gram-negative bacteria and against yeast and mold. Germaben II can be used without additional co-preservatives and is compatible with essentially all cosmetic ingredients, including surfactants and proteins.

Germaben II-E

Germaben II-E

*Preservatives are sold by weight not volume.

Germaben II-E is a clear viscous liquid preservative system with a characteristic mild odor. It is readily soluble at a level of 1.0% in both water/oil and oil/water emulsions, but not in water alone. 

Germaben II-E is a solubilized combination of Germall II with methylparaben and propylparaben in propylene glycol. It is a complete broad spectrum antimicrobial preservative system that is effective against Gram-positive and Gram-negative bacteria and against yeast and mold. 

Germaben II-E was developed for creams and lotions that present special preservation problems involving partial inactivation of parabens by ingredients in the formulation. Germaben II-E can be used in problem formulations, without the need for additional co-preservatives. It is compatible with almost all cosmetic ingredients, including surfactants and proteins.

All the components of Germaben II-E are permanently listed by the EU. Germaben II-E is a complete preservative system, in clear liquid form, that was developed especially for cosmetic creams and lotions that present preservation problems caused by the presence of paraben inactivating materials. 

Germaben II-E includes a total concentration of 20% parabens predissolved in propylene glycol for easy and convenient addition to cosmetic formulations. It minimizes the difficulties associated with incorporating solid parabens. 

Germaben II-E can be conveniently incorporated into hot or cold processed shampoos, creams and lotions during their manufacture. The preferred method of addition is to add it slowly to the cosmetic formulation with good stirring after emulsification and just prior to the addition of fragrance. In fact, some fragrance materials are most effectively incorporated into cosmetics by predissolving them in Germaben II-E and then adding the mixture slowly to the finished formulation. 

Germaben II-E is recommended to be used at a level of 1.0%. This level provides to the product: 0.20% Germall II, 0.10% methylparaben, 0.10% propylparaben and 0.60% propylene glycol. Although Germaben II-E provides excellent antimicrobial preservation, every developed or modified product should be challenge tested to assure preservative efficacy.

LiquaPar Optima

LiquaPar Optima

*Preservatives are sold by weight not volume.

LiquaPar Optima is a broad spectrum preservative used in a wide range of cosmetic products such as: creams, lotions, ointments, exfoliants, lipsticks, liquid and cream makeup, eyeliners, mascaras, etc. LiquaPar is perfect for products ranging from salt scrubs to toners to lotions and creams. Not to mention shampoo and liquid soap.


It is also non-volatile, remains fully stable over a wide pH and temperature range, is non-irritating to the skin, eyes, and mucous membranes, is devoid of skin sensitizing effects, is biodegradable, and presents no pollution hazard. Plus it is fully compatible with plant extract products and is effective as an antimicrobial preservative for aqueous herbal extracts and for cosmetic and pharmaceutical preparations containing plant products.

Owing to its many advantages, LiquaPar Optima is suitable for the preservation of topical pharmaceuticals and cosmetic and toiletry products of all types. Its powerful microbiocidal activity in most systems makes LPO effective in those products, which have been found especially difficult to preserve in the past (shampoos, lotions, creams, and protein-rich systems.) For preservative applications, LPO should be evaluated at concentrations of 0.5-1% depending on the conditions. ISP recommends a use level of not greater than 1%.

Phenonip

Phenonip

*Preservatives are sold by weight not volume.

Phenonip is a preservative that works in a multitude of applications. It is a clear liquid and the application rates vary from .3% to 1% by weight depending on the circumstances. Most applications are in the .3% to .5% range. To preserve 200g of salt scrub at .5% application rate would mean using approximately 1g of Phenonip. This preservative was designed with cosmetics in mind and is especially effective when used in conjunction with oil based products but also works extremely well in aqueous solutions up to a .5% application rate. Phenonip can also tolerate higher temperatures than many other preservatives and still maintain its effectiveness.

INCI Name: Phenoxyethanol (CAS # 122-99-6), methylparaben (CAS # 99-76-3), butylparaben (CAS # 94-26-8), ethylparaben (CAS # 120-47-8), propylparaben (CAS # 94-13-3)
