How do you formulate a ceramide moisturizing serum?
Formulating a ceramide moisturizing serum begins with addressing common skin concerns such as sensitive skin, oily skin, signs of aging, red cheeks, and uneven skin tone. These issues often indicate a compromised skin barrier, leading to dryness, irritation, and buildup of dead skin cells. Focusing on barrier support is essential for achieving healthier skin function and appearance. Key ingredients for hydration and repair Effective formulation relies on clinically effective ingredients. Ceramide NP, ceramide AP, and ceramide EOP—known collectively as essential ceramides—are critical for rebuilding the skin barrier. Hyaluronic acid provides deep moisture, while vitamin B5 calms and softens the skin....
How much niacinamide should be in a toner
A well-formulated niacinamide toner begins with vitamin B3, commonly known as niacinamide. This amino acid–derived cosmetic active addresses uneven skin tone, enlarged pores, and sebum production. It strengthens the skin barrier and helps reduce transepidermal water loss. When paired with stable forms of vitamin C, such as tetrahexyldecyl ascorbate and ascorbyl palmitate, the toner also supports brighter and firmer-looking skin. Formulating with care pH levels and water phase The base of this toner typically starts with demineralized water in the water phase. Maintaining a pH of 6.4 helps align the product with the skin’s natural pH balance. Adjustments using citric...
What should I ask a manufacturing lab when considering cosmetic formulation services
Choosing the right formulation company is key to successful product development. Whether you’re launching skincare products, bath and body care, hair care, or natural beauty products, working with formulation experts ensures your cosmetic formulas are safe, effective, and meet regulatory standards. Partnering with a formulation chemist or product developers streamlines the process from idea to physical product samples. Understanding cosmetic formulation development During cosmetic formulation development, labs focus on ingredient sourcing, product testing, and building a product information file. Cosmetic ingredient development, custom formulation services, and custom formulation description package often go hand‑in‑hand. This holistic approach helps brands handle custom...
What are the best practices for sustainable ingredient sourcing?
Sustainable ingredient sourcing begins with transparent supply chains and raw materials selection. When creating cosmetic formulas, whether for skincare products, hair care products, lip care, or personal care products, knowledge of cosmetic ingredients and cosmetic raw materials is crucial. Ingredient suppliers must provide ingredient names or INCI names, certificate of analysis, safety data sheets, and comply with regulations like California Proposition 65 and Good Manufacturing Practice Draft Guidance. Sourcing suppliers involves evaluating global supply chains and container sale options to ensure ethical practices and environmental sustainability. Working with certified suppliers and trade compliance Ingredient sourcing in the formulation stage must...
How do regulations and industry standards support formulation transparency?
Formulation transparency is becoming a core value in the beauty and personal care space. It refers to the open communication of cosmetic ingredients used in a cosmetic product, including their source, function, and concentration. This practice supports consumer trust and reflects ethical practices, especially as the clean beauty movement gains traction among beauty enthusiasts. Ingredient disclosure, full ingredient transparency, and proper ingredient labeling are now expected by informed consumers seeking safe and non-toxic ingredients. Role of regulations in ingredient disclosure Regulatory standards require manufacturers to provide full ingredient lists using INCI names to ensure consistency and accuracy. These frameworks aim...
What is the purpose of pH adjusters in cosmetics
The potential of hydrogen, or pH level, is central to cosmetic science. Measuring the hydrogen ions in water-based solutions—or even plant oils—allows cosmetic chemists to assess the effect on the skin barrier and acid mantle. Tools like a pH meter, glass electrode, and pH strips give insight into formulation pH, helping ensure a pH-balanced cosmetic. This matters in skin care products, hair care products, facial mists, and even mineral foundation powders to protect the skin microbiome and hydrolipidic film. Common pH adjusters and regulatory considerations Cosmetic pH adjusters or pH regulators include acids and bases like citric acid, sodium hydroxide,...
Why is thermal stability important in cosmetic formulation compatibility
Thermal stability refers to a formulation’s ability to maintain its structure, chemical composition, and physical properties when exposed to elevated temperatures. This includes maintaining an oil in water emulsion without liquid syneresis, preventing thermal decomposition of cosmetic actives like vitamin E and UV filter compounds, and avoiding chemical changes such as oxidation of carbonyl group-bearing ingredients. It is essential that cosmetic product designers consider thermal stress during the formulation process to ensure product quality in all climatic zones. Why stability testing and stability studies are crucial Stability test procedures include real-time stability evaluation, accelerated stability testing, and long-term stability testing....
Why is encapsulation used in cosmetic formulations
Encapsulation is widely used in cosmetic formulations to enhance the delivery and stability of active ingredients in a variety of cosmetic products. This technique involves enclosing a core material, such as vitamin C or a moisturizing active ingredient, within a shell material to form a stable encapsulation system. The encapsulation process is particularly valuable in skin care and personal care due to its ability to control how and when ingredients are released onto the skin. What is encapsulation Encapsulation refers to the process of surrounding an active ingredient with a shell that protects it from environmental exposure and improves ingredient...
What is nanotechnology and how is it used in cosmetics
Nanotechnology involves working with materials at the nanoscale, typically between 1 and 100 nanometers. At this scale, materials exhibit unique properties that can enhance cosmetic products in various ways. These enhancements include better skin absorption, improved stability, and more precise delivery of active ingredients to targeted skin layers. Benefits in cosmetic formulations Incorporating nanotechnology in cosmetic formulations allows the creation of more effective products. Using nano-sized drug delivery systems such as nanoemulsion systems or liposome nanoparticles, formulators can improve how active compounds interact with human skin. This leads to enhanced skin penetration profiles and more effective performance of active agents...
