General Description
Propylene Glycol is a synthetic organic compound widely used across various industries, including cosmetics, pharmaceuticals, and food production. It is a colorless, odorless, and slightly viscous liquid with excellent humectant and solvent properties. Due to its ability to retain moisture, it is a key ingredient in many skincare and personal care formulations. Manufacturers and suppliers commonly buy, sell, and wholesale Propylene Glycol in bulk for industrial and commercial applications.
Uses in the Cosmetics Industry
Propylene Glycol is a crucial ingredient in the manufacture and sales of cosmetic products due to its moisturizing, emulsifying, and penetration-enhancing properties. It is widely found in:
- Moisturizers and lotions – Helps maintain skin hydration.
- Shampoos and conditioners – Enhances product texture and performance.
- Makeup products – Acts as a solvent to blend ingredients evenly.
- Deodorants and antiperspirants – Prevents drying out and ensures smooth application.
- Cleansers and serums – Aids in ingredient absorption and enhances efficacy.
Many cosmetic brands and laboratories buy Propylene Glycol in bulk or wholesale to develop high-quality skincare and haircare products.
Side Effects and Hazards
While Propylene Glycol is generally considered safe by regulatory agencies such as the FDA and EU Cosmetics Regulation, some individuals may experience side effects, including:
- Skin irritation – In rare cases, it can cause redness or allergic reactions.
- Eye irritation – Direct contact may lead to discomfort or temporary irritation.
- Sensitivity concerns – Those with eczema or sensitive skin should use it with caution.
Although Propylene Glycol is non-toxic in small amounts, excessive exposure, especially in industrial settings, may pose health risks. It is important for cosmetic manufacturers and bulk buyers to ensure compliance with safety guidelines when handling and formulating with this ingredient.
For businesses looking to buy Propylene Glycol for manufacturing, wholesale, or bulk sales, it is essential to source it from reputable suppliers to ensure high purity and compliance with industry standards.

THE STORY OF PROPYLENE GLYCOL
Propylene Glycol: The Multi-Functional Moisture Carrier for Modern Formulations
Propylene Glycol is a versatile, low-viscosity liquid widely used in cosmetic and personal-care formulations as a humectant, solvent, and penetration enhancer. Known for its excellent moisture-binding ability and ingredient compatibility, it improves hydration, texture, and active delivery.
Produced Through Controlled Chemical Synthesis for High Purity
Propylene Glycol is manufactured through the hydration of propylene oxide under controlled conditions. The resulting product is purified by distillation to meet cosmetic- and pharmaceutical-grade standards, ensuring consistent quality, safety, and formulation reliability.
Hydration Boost, Ingredient Solubility & Enhanced Performance
In cosmetics, Propylene Glycol acts as a humectant, solvent, and carrier.
It attracts and retains moisture, dissolves water- and oil-soluble actives, and improves skin feel and product spreadability. Its ability to enhance ingredient penetration makes it valuable in skincare, haircare, oral care, and topical formulations.
Safe, Effective & Widely Approved Across Personal-Care Products
Used in moisturizers, serums, cleansers, shampoos, conditioners, deodorants, and oral-care products.
Recommended usage: typically 1–10%, depending on formulation needs.
Store in tightly sealed containers in cool, dry conditions.
Propylene Glycol is non-volatile, biodegradable, and globally approved for cosmetic and pharmaceutical use, offering dependable performance and formulation flexibility.
