When embarking on your journey into cosmetic formulation, one of the most common questions is: Where should I start? I always recommend beginning with anhydrous products—formulations that do not contain a water component. Anhydrous products are not only simpler but are also safer to make for beginners. These products consist of oils, butters, waxes, and other lipid-based ingredients, all of which do not support the growth of bacteria, yeast, or mold. This eliminates the need for water-soluble preservatives, which are essential in formulations containing water.
But the advantages of starting with anhydrous products go far beyond just safety. Working with these formulations provides a fantastic opportunity to familiarize yourself with different oils, butters, and waxes—commonly referred to as lipids—and how they behave on the skin. Understanding the properties of these ingredients will give you a significant edge when you begin incorporating water into your formulations. Let’s dive deeper into why anhydrous products are ideal for beginners, and explore some of the key ingredients you’ll be working with.
Why Start with Anhydrous Products?
Microbial Safety: Since anhydrous products do not contain water, there’s no environment for bacteria, yeast, or mold to grow. This makes them safer to make at home and reduces the need for a broad-spectrum preservative system in most cases.
Formulation Simplicity: Anhydrous products are typically easier to formulate because they consist of oils, butters, and waxes, without the need to manage complex emulsions or incorporate preservatives.
Understanding Lipids: By starting with these products, you gain valuable insight into how different oils and butters feel on the skin, their absorption rates, and their unique benefits. This knowledge is crucial when you progress to more complex formulations, such as emulsions (products containing both water and oil).
Wide Variety of Products: There is a vast range of anhydrous products you can create, including lip balms, body balms, facial oils, whipped body butters, and salves. These types of formulations are ideal for experimenting with different combinations of oils, butters, and waxes.
Let’s take a look at some popular anhydrous products and the oils and butters that can form the backbone of these formulations.
Types of Anhydrous Products You Can Start With
Lip Balms: A great first project, lip balms are easy to make and require minimal ingredients. Common ingredients include beeswax, shea butter, and oils such as jojoba or coconut oil.
Body Balms and Salves: These thicker formulations are designed to provide long-lasting moisture and protection to the skin. They often feature a combination of waxes like beeswax or candelilla wax, along with rich butters such as cocoa butter and nourishing oils like sweet almond or olive oil.
Whipped Body Butters: These luxurious, airy products are made by whipping together oils and butters to create a light, fluffy texture. Butters like shea and mango butter are popular choices, along with fast-absorbing oils like jojoba or grapeseed oil.
Facial Oils: These are blends of carrier oils specifically chosen for their lightness and skin benefits. Jojoba oil, rosehip seed oil, and squalane are all popular for facial formulations due to their light texture and skin-loving properties.
Understanding Your Lipids: Carrier Oils and Butters
When working with anhydrous products, you’ll encounter a wide range of carrier oils and butters, each with its own unique properties. Knowing how each one feels on the skin, how quickly it absorbs, and the specific benefits it offers is key to creating effective formulations. Here are some of the most commonly used oils and butters for beginners:
Carrier Oils:
Jojoba Oil: Actually a liquid wax, jojoba oil closely mimics the skin’s natural sebum, making it a great moisturizer. It’s lightweight, non-greasy, and absorbs quickly, making it a fantastic choice for facial oils or light body oils.
Sweet Almond Oil: A gentle, nourishing oil that’s rich in fatty acids, sweet almond oil is ideal for all skin types, including sensitive skin. It has a medium absorption rate and works well in a variety of products, from body butters to lip balms.
Coconut Oil: Known for its solid consistency at room temperature, coconut oil is deeply moisturizing and commonly used in body butters and balms. However, it can feel greasy on the skin, so it’s best blended with other oils for a balanced texture.
Rosehip Seed Oil: This luxurious oil is packed with antioxidants and essential fatty acids, making it a great choice for anti-aging formulations and facial oils. Rosehip seed oil absorbs quickly and leaves the skin feeling soft without a heavy residue.
Grapeseed Oil: A lightweight, fast-absorbing oil, grapeseed oil is perfect for oily or acne-prone skin. It is also rich in antioxidants, making it a great addition to facial oils or lightweight body oils.
Butters:
Shea Butter: One of the most popular cosmetic butters, shea butter is rich, creamy, and deeply moisturizing. It is well-tolerated by most skin types and can be used in a wide range of formulations, from body butters to lip balms. Refined shea butter has a neutral scent, while unrefined shea has a strong, nutty aroma.
Cocoa Butter: A firm butter with a delicious natural scent, cocoa butter is commonly used in balms and body butters to create a protective barrier on the skin. It is particularly helpful for dry or cracked skin and gives formulations a thick, creamy texture.
Mango Butter: This butter is slightly firmer than shea but has a lighter feel on the skin. Mango butter is highly moisturizing and provides a smoother, silkier finish, making it ideal for products like whipped body butters and facial balms.
Kokum Butter: A harder butter that is less greasy than shea or cocoa butter, Kokum butter is a fantastic alternative when you want a lighter feel in your formulations. It is highly moisturizing and known for its ability to restore skin elasticity.
Broad-Spectrum Preservation for Water-Exposed Anhydrous Products
While most anhydrous products do not require preservatives due to their lack of water, there is one exception: when the product is likely to be exposed to water. For example, if you’re making a sugar scrub for use in the shower, water can introduce bacteria, mold, or yeast into the product. In these cases, you will need to incorporate a broad-spectrum, oil-soluble preservative like Phenonip to protect your formulation.
Starting with anhydrous formulations provides a solid foundation for new formulators. Not only are these products safer and easier to make, but they also give you invaluable experience with the oils, butters, and waxes that form the building blocks of more advanced products. By understanding how these ingredients feel on the skin and how they interact with one another, you will be well-equipped to tackle more complex formulations down the road.
Take the time to experiment with different carrier oils and butters, and don’t be afraid to tweak your formulas to achieve the perfect balance of texture, absorption, and skin benefits. Starting with anhydrous products will not only build your confidence but also give you a deeper understanding of the art and science of cosmetic formulation.
