For cosmetic manufacturers, the selection and procurement of raw materials are critical to product quality and market success. Glyceryl Stearate and PEG-100 Stearate is a widely used, versatile emulsifier that forms the backbone of many stable and desirable cosmetic formulations. This guide provides essential information for procurement professionals and R&D teams on why and how to buy this key ingredient.

Understanding the Core Functionality
Glyceryl Stearate and PEG-100 Stearate is a non-ionic emulsifier that excels at creating oil-in-water (O/W) emulsions. It's a blend that combines the properties of Glyceryl Stearate and PEG-100 Stearate, allowing formulators to achieve stable emulsions with a pleasant, silky texture. Its primary role is to bind oil and water phases, preventing separation and ensuring a uniform product consistency. This makes it indispensable for lotions, creams, serums, and various haircare products. For manufacturers, identifying reliable suppliers of this ingredient is the first step to consistent product quality.

Key Benefits Driving Purchase Decisions
Several factors make this emulsifier blend a popular choice for manufacturers. Firstly, the texture it imparts is a major draw: it provides a light, smooth, and non-greasy feel on the skin, which is highly valued in the cosmetic industry. Secondly, its formulation flexibility is a significant advantage. Unlike some emulsifying waxes that also act as thickeners, this blend allows formulators to control viscosity independently, enabling greater creativity and customization in product development. Thirdly, its inherent stability – including thermal and freeze-thaw stability – along with broad compatibility with other ingredients and pH ranges, ensures reliable performance in finished products. These benefits directly contribute to the marketability and efficacy of the final cosmetic item.

Factors to Consider When Buying
When purchasing Glyceryl Stearate and PEG-100 Stearate, several quality aspects are crucial. Look for cosmetic-grade material that meets purity standards. Understanding the blend ratio (typically a 50/50 split of Glyceryl Stearate and PEG-100 Stearate) is important, as variations can affect performance. Always check the supplier's documentation, including technical data sheets (TDS) and Safety Data Sheets (SDS), to ensure the product meets your formulation requirements and safety standards. For manufacturers, especially those operating at scale, identifying suppliers who can guarantee consistent quality, reliable supply chains, and competitive pricing is paramount. Many manufacturers in China offer high-quality cosmetic-grade ingredients, making them a key sourcing region.

Typical Applications and Usage Rates
This emulsifier is versatile, finding use in a wide range of products:

  • Skincare: Lotions, creams, moisturizers, serums, facial cleansers.
  • Haircare: Conditioners, hair masks, leave-in treatments, styling creams.
  • Color Cosmetics: Emulsified foundations, concealers.
  • Personal Care: Roll-on deodorants, sunscreens.
Usage rates typically range from 1% to 5% of the total formulation, added to the oil phase during heating. It's advisable to consult specific formulation guides or supplier recommendations for optimal results.

Where to Buy Effectively
For manufacturers seeking to buy Glyceryl Stearate and PEG-100 Stearate, focusing on suppliers with a proven track record in the cosmetic ingredients market is essential. Companies that provide detailed specifications, reliable delivery, and excellent customer support are ideal partners. Exploring manufacturers in China can offer competitive pricing without compromising on quality, provided due diligence is performed on supplier credentials.

In conclusion, Glyceryl Stearate and PEG-100 Stearate is a fundamental ingredient for any cosmetic manufacturer focused on creating high-quality emulsions. By understanding its properties, considering key quality factors, and sourcing from reputable suppliers, you can effectively integrate this versatile emulsifier into your product lines, driving both innovation and consumer satisfaction.
