13 propylene glycol

1,3 propylene glycol (propylene glycol) is a natural green alternative to propylene glycol derived from corn sugar. It is used as a moisturizer, hair and skin conditioner, preservative and solvent. It has a light, non-sticky, slightly dry skin feeling.
Propylene glycol increases hydration when used in hair and body products, and at 5%, propylene glycol outperforms propylene glycol and butanediol. When combined with glycerol, propylene glycol shows a synergistic effect that can reduce the viscosity of glycerol while providing the benefit of increased hydration levels. At levels up to 75%, it shows a small likelihood of irritating or sensitizing the skin.

In surfactant systems, propylene glycol increases the transparency and viscosity of the surfactant system while reducing the amount of salt required to thicken the product. It improves the glitter foam and produces a more elegant system with more delicate foam and more dense foam.
In hair care products such as shampoos, conditioners, leave-free conditioners or styling AIDS, it provides a cleaner feeling after rinsing while increasing moisture, improving untangling, reducing static electricity and improving wet and dry combing.
In all products, it reduces the freezing point and improves the stability of freeze-thaw and heating tests.
Propylene glycol can enhance the efficacy of the preservative. When combined with a preservative containing phenoxyethanol, its efficacy against yeast, gram-positive and gram-negative bacteria, as well as molds, is demonstrated.
Propylene glycol is an excellent solvent for difficult-to-dissolve ingredients such as salicylic acid, ferulic acid, allantoin and ascorbic acid.
Major advantage
Light, non-sticky skin
A green alternative to propylene glycol from renewable resources
Viscosity enhancer
Transparency enhancer for surfactant systems
Improve freeze-thaw and thermal stability
Low potential for skin irritation or sensitization
It is a good solvent for insoluble components and plant extracts
Improve the efficacy of preservatives
It is hygroscopic and moisturizes the skin and hair well.
1, 3-propylene glycol can be used as:
Solvents and stabilizers in film preparation.
Polyesters such as polypropylene terephthalate (PPT), polyallyl isophthalate (PPI) and polypropylene naphthalate are synthesized by polycondensation reaction with terephthalic acid, isophthalic acid and 2, 6-naphthalate.
The reactants of 7, 8-benzoquinoline were prepared by cyclization with 1-naphthylamine catalyzed by IrCl3.
Store below 40°C. Avoid exposure to UV light, air and heat.
