Description

Cosgard – Broad Spectrum, High Efficiency

Cosgard is a liquid preservative system based on a synergistic combination of four components: benzyl alcohol, salicylic acid, glycerin, and sorbic acid. It is broad spectrum and approved by certification bodies for natural cosmetics. Its essential role is to ensure complete microbiological protection of water-containing formulas, effectively preventing the growth and multiplication of Gram-positive and Gram-negative bacteria, yeasts, and molds.

Ingredients (INCI): Benzyl Alcohol, Salicylic Acid, Glycerin, Sorbic Acid.

Technical Characteristics

  • Appearance: Yellowish liquid, specific aromatic odor.
  • Solubility: Soluble in alcohols and glycols, miscible in the water phase.
  • pH Range: 3.0 - 8.0. 
  • Indicative Dosage: 0.6% - 1.0%

Main Properties

  • Broad-Spectrum Activity: Destroys and inhibits a wide range of pathogens (aerobic and anaerobic bacteria, fungi, storage molds).
  • Eco/Bio Compatibility: One of the most widely used solutions to replace controversial synthetic preservatives.
  • Versatility: Does not affect the viscosity of creams or strain polymeric hydrophilic gel networks.

Applications

  • Emulsions of all types, moisturizing day and night creams, body lotions, eye creams.
  • Rinse-off hygiene products: shampoos, shower gels, facial cleansers, intimate washes.
  • Hair care products: conditioners, hair masks, scalp serums.
  • Clear aqueous formulations: toners, micellar waters, facial sprays, serums, gels.
  • Fluid makeup products: water-based foundations, concealers, mascaras.

Formulation Guide

  • Procedure: Cosgard is added during the final phase of formulation, below 40°C, with thorough stirring for complete dispersion.
  • pH Value: Optimal pH range is 3.0-8.0.
  • Recommended Usage Dosage: 0.6% - 1.0%. A standard dosage of 1% provides optimal long-term preservation for most formulas.
  • Stability: Heat-sensitive; must be added at low temperatures, typically below 40°C.
  • Odor Management: Cosgard has a characteristic medicinal odor resembling bitter almonds, noticeable in unfragranced formulas. It can be masked using floral waters, essential oils, or natural fragrance extracts.

Safety in Use and Storage

Safety Profile: Safe, extensively dermatologically tested raw material for cosmetics. In rare cases, on extremely sensitive skin or skin with rosacea, it may cause a temporary warming sensation or mild redness, which is why a skin patch test is recommended. As a product containing Salicylic Acid, its use is governed by strict safety rules in the European Union. According to Cosmetic Regulation (EC) No 1223/2009, products containing salicylic acid should not be used in formulations intended for children under 3 years of age, except in rinse-off products (shampoos, shower gels).
Precautions: For external cosmetic use only. In its pure, concentrated state, the liquid may cause skin and eye irritation; handle using protective equipment (gloves). In case of eye contact, rinse immediately with plenty of clean water. Do not use in leave-on products for children under 3 years old. Keep out of reach of children.
Storage: Keep in the original tightly closed container, in a dry, cool place, protected from light.

Et alsidigt og effektivt konserveringsmiddel, der er godkendt af både Ecocert og Cosmos. Farven er let gullig, men det betyder ikke noget i det færdige produkt.

Cosgard is the preservative I use in absolutely all the cosmetic products I make. By observing the recommended dosage, I have never had the unpleasant surprise that any of the cosmetics I have made has altered during its shelf life.

I've noticed that, unlike vitamin E, cosgard products keep better. I wonder if we could combine them. I don't see the problem, but I haven't tried it yet.

One of the preservatives I trust and decently priced. I use it in creams and the resulting texture was exactly how I wanted. It is stable, had no reaction with other ingredients. Recommendation.

Cosgard is one of the products not to be missed among the ingredients in the ingredients in my supply. I use it in the composition of all the creams I prepare. It is extremely effective, thus guaranteeing the shelf life of the created product.

I fully appreciate both the effectiveness of this preservative and the wide, permissible pH range. But what I disliked just as much with the last batch purchased (no. 78784) was the effect of changing the final odor of an aqueous serum into a too strong, pungent, hospital disinfectant...so I will no longer be able to use it for products to which I cannot add essential oils or fragrances on the one hand, and on the other hand, it has lowered my pH by more than one unit(!!!! ) the pH of all the products I have used it on ( creams, cleansers, lotions, serums), which has never happened to me before and for sure this has cost me stress and quite a long extra time for adjustment; basically, it took more time for adjustment and countless checks than the actual realization of the products, and such a pH issue I really didn't expect from Cosgard who I have worked with for years without any problems so far 🙉. The 4* rating is for Cosgard in general, so as not to damage its reputation; for this batch however, please infer that I could only offer a very low one and please do some more tests to confirm/refirm the problem I have noticed. 🙏🏻

I used this product to prepare an exfoliating serum. I think it is a good product since the serum has kept its consistency and properties for more than 3 months (minimum shelf life of the serum).
