Description
RoseGuard – Multifunctional Antimicrobial Protection with a Delicate Rose Scent
RoseGuard is a state-of-the-art synergistic blend composed of phenethyl alcohol and caprylyl glycol, designed to provide effective preservation and exceptional sensoriality to cosmetic products. It acts as a multifunctional additive: on one hand, it ensures broad-spectrum protection against bacteria, yeasts, and molds, and on the other hand, it functions as a masking agent, imparting a discreet and pleasant rose scent to the product. It is the ideal solution for formulations aiming for a "preservative-free" label (without traditional preservatives).
Ingredients: Phenethyl Alcohol, Caprylyl Glycol.
Characteristics
- Appearance: Clear, colorless liquid.
- Scent: Floral, delicate, rose-specific.
- Solubility: Limited water solubility (up to approx. 1.2%), easily soluble in oils and glycols.
- Technology: Synergistic combination of microbial inhibitors with a broad spectrum of efficacy.
- Origin: Nature-identical ingredients and plant derivatives, accepted in conventional and modern cosmetics.
Main Properties
- Broad Spectrum Protection: Effective against a wide variety of microorganisms, ensuring the microbiological stability of complex formulas.
- Scent: Covers the unpleasant odors of certain raw materials and provides a light floral olfactory note. The delicate rose scent can mask unwanted odors in the formula without using added fragrance.
- Emollient and Moisturizing: The caprylyl glycol in the composition offers skin hydration and smoothing benefits.
- pH Independence: Unlike organic acid-based preservatives, RoseGuard maintains its efficacy across a wide pH range.
- Efficacy Booster: Caprylyl glycol acts as a "penetrator" of the bacterial cell membrane, making the preservation system much more potent.
Usage Recommendations
General recommended dosage: 0.8% - 1.5%.
It is suitable for modern and gentle skin care formulations. It can be used alone or in combination with other antimicrobial agents to reduce their dosages.
Applications
- Face and body care emulsions, creams, lotions.
- Cleansing products, cleansers, shower gels, shampoos.
- Hydrogels and lipogels.
- Serums and elixirs.
- Products for sensitive or reactive skin.
Formulation Guide
- Procedure: In emulsions, it is preferably added in the final phase, after the emulsion has formed. In clear aqueous solutions, it may require a solubilizer if the solubility threshold of 1.2% is exceeded.
- Temperature: Addition at temperatures below 40°C is recommended.
- pH Range: Effective in the pH range of 3.0 - 9.0
- Technical tip: RoseGuard combines excellently with chelating agents (such as Phytic Acid) to increase the resistance of the preservation system against Gram-negative bacteria.
Frequently Asked Questions (FAQ)
Why is RoseGuard considered a "preservative-free" option?
Because its ingredients (phenethyl alcohol and caprylyl glycol) are primarily classified as a fragrance and an emollient, respectively. Thus, on the label, the product does not appear to have preservatives listed in Annex V of the European Cosmetic Regulation, although the formula is microbiologically protected.
Does RoseGuard change the scent of my cream?
Yes, it has a discreet rose scent. In most cases, this scent is considered an advantage as it provides a pleasant note to the finished product, eliminating the need for additional fragrance.
Is it suitable for people allergic to fragrance?
Phenethyl alcohol is a natural component of rose essential oil, but RoseGuard is an isolated form. Although it is much safer than complex synthetic fragrances, testing on a small area of skin is recommended for extremely sensitive individuals.
Safety in Use
Profile: Safe, biodegradable, and environmentally friendly ingredient. Dermatologically well-tolerated at recommended doses.
Precautions: Keep out of reach of children. Avoid direct contact with eyes in pure form. Do not ingest.

Did not work unfortunately. Destroyed my emulsion and made it water thin. More information needed about which emulgators are compatible.
