Propylparaben

Propylparaben is one of the most common preservatives and is widely used in pharmaceuticals and cosmetology. One of the advantages of this preservative is its environmental safety. This substance may be naturally present in some types of plants; it quickly decomposes when it enters the soil and does not cause harm to the environment. Basic properties:
- Effective against mold fungi;
- Prevents the proliferation of gram-positive bacteria;
- Does not have a sensitizing effect;
- Does not irritate the skin;
- Non-toxic in the indicated dosages. Propylparaben is used over a wide pH range, but has the greatest effect at pH less than 7.0. The preservative is used in any cosmetic products:
- Masks and balms;
- Creams and lotions;
- Shampoos and gels;
- Toothpastes. Method of application Propylparaben is highly soluble in alcohols and propylene glycol, but slightly soluble in water. As the temperature rises, solubility in water increases, so it is introduced into the aqueous phase at a temperature of about 95? C. Recommended input percentage:
- Toothpastes, mouth rinses – 0.001-0.05%;
- Creams, lotions, shampoos and others – 0.05-0.2%. Complies with: NF, BP, Ph Eur and SL98I standards. The component should be stored in a dark and cool place.
