Jojoba Oil in Soap Making
When formulating for soap making, there are a wide variety of oils available to use. One that is a favorite among soap makers for promoting skincare is jojoba oil. Pronounced as “ho-ho-ba”, jojoba oil is actually a wax and a versatile ingredient that can instantly enhance any bath & beauty product. Using jojoba oil in soap making is great for adding moisturizing and conditioning properties to your finished product. Jojoba oil’s amazing moisturizing properties is also ideal for massage oils, lotions, lip balms, and and as carrier oil for perfumes.
What is Jojoba Oil
Jojoba oil is the liquid produced in the seed of the Jojoba plant (scientifically known as Simmondsia Chinensis). Jojoba plants are a shrub, which is native to southern Arizona, southern California, and northwestern Mexico. The oil makes up approximately 50% of the jojoba seed by weight.
The terms “jojoba oil” and “jojoba wax” are often used interchangeably because the wax visually appears to be a mobile oil, but as a wax it is composed almost entirely (~97%) of mono-esters of long-chain fatty acids and alcohols (wax ester), accompanied by only a tiny fraction of triglyceride esters. Jojoba oil is very unique and are known for its high vitamin E content that gives it an almost indefinite shelf life as compared with other vegetable oils that has a typical shelf life of a few months to a year.
What is an ester? An ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH (hydroxyl) group is replaced by an –O–alkyl (alkoxy) group. In jojoba wax, both the acid and ester alcohol portions have 20 or 22 carbon atoms, and each has one unsaturated bond. The unsaturated fatty acids allow it to look like a liquid, instead of a solid, like other waxes that may come to mind, such as beeswax or soy wax. Jojoba wax does not oxidize, it does not become rancid and it does not break down under high temperatures or pressure. This gives it an incredibly long shelf life and will not cause DOS in your soaps.
In the 1960s, sperm whale were being hunted for their oil which comprised of ninety percent wax esters. Sperm whale oil were so highly demanded and were widely used in thousands of health applications and cosmetic products. The demand for sperm whale oil grew as the industry ballooned and hunting for sperm whales became a great source of income for many during that time. This insatiable hunting for the poor sperm whales resulted in them becoming endangered species within a few years.
In 1971, the United States outlawed the importation of whale oils into the United States leading to the discovery and commercial farming of Jojoba plants to replace the sperm whale oil. It was found that jojoba oil is in fact far more superior to whale oils (also known as squalene) in so many ways and is more beneficial to human health. Of more than 350,000 identified plant species, jojoba is the only one which produces significant quantities of liquid wax esters akin to the natural restorative esters human sebaceous glands produce. Furthermore, the Jojoba shrub is also used to prevent dry regions from desertification by supporting vegetation and wildlife. Today, Jojoba oil has become so prominent with wide applications in many variety of products especially for skin care.
Using Jojoba Oil in Soap Making
You can use varying amounts of jojoba oil in scrubs, lotions or lip balms, but it shouldn’t be used more than 10% in soap making because it tends to weigh down lather. Having too much in your soap recipe will create a somewhat soft bar with poor lather as jojoba has a lot on non-saponifiable oils. It’s also very expensive compared to other soap making oils, so using too much is impractical for many soap makers.
SAP value of Jojoba Oil
Saponification (SAP) values are the numeric values that allow you to calculate the precise amount of sodium hydroxide (NaOH) or potassium hydroxide (KOH) required to fully saponify a given weight of oil/s.
The SAP value for using Jojoba oil in soap making is
- 0.066 with Sodium Hydroxide (NaOH) for Bar Soap
- 0.092 with Potassium Hydroxide (KOH) for Liquid Soap
Characteristics of Jojoba Soap
Bubbly lather: No
Creamy/Stable lather: Mild
