What to Know About Sodium Lactate

You may have seen the ingredient “sodium lactate” listed in some of your skincare or haircare products. If so, here’s what you need to know about sodium lactate.

What Is Sodium Lactate?

Sodium lactate is an unsung hero in the beauty world. It is a naturally-derived salt of fermenting – and then neutralizing – lactic acid. Lactic acid does not come from dairy. It is derived by fermenting sugars found in corn and beets. It also occurs naturally in animal and human tissue. In fact, it is a natural component of the top layer of skin and forms part of the Natural Moisturizing Factor (NMF).

Why Sodium Lactate?

Why is sodium lactate a beneficial ingredient in beauty products, from serums to peels and everything in between? For one thing, much like hyaluronic acid, it’s a great humectant that draws water into the skin. It also serves as a skin butter, helping formulas maintain the skin’s natural pH balance. It can enhance the properties of preservatives, and is mildly exfoliating.

We like to use sodium lactate in our cold process bar soaps. It makes them harder, smoother and more long lasting. We hope to include this beneficial, naturally-derived ingredient in future formulas.

Are There Downsides to Using Sodium Lactate?

Clearly, those who are sensitive to this ingredient should avoid it. It can also increase sun sensitivity, so wearing a sunscreen over it when outside is advised.

Should I Try Products Containing Sodium Lactate?

Why not? It’s an ingredient that may be particularly beneficial for aging skin, as sodium lactate in skin declines as we age. And given the large variety of products containing this ingredient, you should be able to find one that suits your needs. If you are dissatisfied with hyaluronic acid, if you’re looking for a naturally derived moisturizer, night cream, or peel, then give it a try. If you’d like to search for products containing sodium lactate, visit incidecoder.com and type the ingredient name into the search field.

Haircare mistakes and curly hair

Haircare Mistakes And Curly Hair

Which haircare mistakes to we tend to engage in? A lot can depend on your hair type and lifestyle. For those with curly hair, a little TLC is often required due to the nature of the curl strands and their susceptibility to damage. Wavy and curly hair are created by the presence of an oval hair follicle. Curly hair is softer and more susceptible to breakage. It also tends to have less sebum present, making it drier. Hence, it’s important to know which practices can negatively impact on curly locks, and what to do instead. Below are some of the most common haircare mistakes.

Shampooing too often

As mentioned before, curly hair tends to be drier. This can also extend to the scalp. Therefore, it’s not necessary to hit the shampoo bottle every day, or even every other day. A lot depends upon how active you are and what condition your curls are in. According to the experts at Ouidad , it’s ok to wash or co-wash your hair between 1 and 3 times per week. As a general rule, the drier your hair and scalp, the less often you should wash it.

Using the wrong shampoo

There are a mind-boggling number of shampoo formulas out there, and it’s important to use one that is tailored to your hair type. If your hair is extra curly, it will benefit from an extra-moisturizing formula. Or opt for what is called co-washing (conditioner-only washing). Most conditioners contain a few cationic surfactants (cleansers) like benhetrimonium chloride, which remove dirt without stripping the hair. If your hair and scalp tend to be dry, this may be the best option for you. Also avoid shampoos containing a lot of foaming agents like sodium laureth sulfate and cocamide DEA, which can cause allergic reactions and tend to be drying. Believe it or not, you don’t need lather to get hair clean. If in doubt, read the ingredient labels before buying. For a list of common shampoo ingredients read this Newsweek article.

Using the wrong styling products

It’s important for people with curly hair in particular to use styling products. They help with frizziness, dryness, tangling and other issues. Even if you air-dry your hair, it’s a good idea to add protection and definition with styling products. However, the wrong styling products can wreak havoc on your hair. For example, styling gels containing alcohols can dry out your hair. Opt for alcohol-free cream formulas that add definition and shine. Another problematic ingredient is silicones. On the label, they usually end in -one or -oxane. They are synthetic polymers that create slip and providing some heat protection. While not all silicones are created equal, they all do have a tendency to build up on your hair, ultimately leaving it dry and dull. They are hydrophobic, which means they are hard to wash out. You’ll then need a clarifying shampoo to remove them, which causes more drying, and on and on. This is especially true for thick silicones like dimethicone. It’s a cycle that you just don’t want to get into.

If you still want to use silicones, opt for a water-soluble one like cyclomethicone.

Not protecting your hair from the elements

Whether or not you color your hair, this is a common mistake that can really cost you down the line. Things like heat, humidity, chlorine, and ultraviolet light have an especially strong impact on curly hair. Aside from avoiding pools and sunlight, there are few things that you can do before hitting the pool or the beach. Yes, you can apply your barrier sunscreen to hair. Usually the ingredients found in sunscreens for the skin are ok for the hair, too. (Yes, you should be using sunscreen on your skin, too.) You can also try products containing oils like jojoba, carrot seed oil, red raspberry oil, almond oil, and shea butter. These ingredients provide natural sunscreen protection. Look for brands like Alba Botanica, or take a look at our All Purpose Dry Oil. If you don’t have any products available, wear a hat.

Too much heat styling

Let’s face it, we all life hectic lifestyles that often necessitate quick hair drying. However, it’s important that we give our curly hair a break from heat styling whenever possible. Even with a diffuser, hair dryers can damage the hair cuticle and dry out curly hair. Sometimes we can avoid heat styling by getting the right haircut. Also buy the best blow dryer you can afford, usually an ionic or ceramic hair dryer, or a combination of both. They tend to cost more than regular hair dryers, but it’s worth it to get less frizz and a shorter drying time. However, air drying is best for curly hair. The right styling product can make your curly hair wash-and-go.

Over-manipulation of hair

Again, a good haircut makes over-manipulation of hair less likely to occur. One should also never comb out curly hair when it’s dry. Use a conditioner or cowash that detangles and use a wide-tooth comb to detangle gently. Separate tight curls with the fingers if possible. Don’t over-brush.

Not protecting your curls while you sleep

It’s so easy to protect your curly hair at night. Just buy a satin sleep cap or a silk pillow case. The fabric helps to reduce friction, reducing damage to your curls while you sleep. Also avoid wearing tight bands or other restraints in your hair while you sleep. Curlers are a no-no! A silk pillowcase is also kinder to your face.

Silicones in skincare and haircare

Pros and Cons of Silicones in Skincare and Haircare

Why Silicones in Skincare and Haircare?

You may have noticed that many different silicones can be found in skincare and haircare products today. There are a number of reasons why formulators – and customers – like products containing silicone. With many names, some ending in “oxane”, they are in cosmetics, as well. There are also reasons to be cautious when using skincare and haircare products containing silicone. It’s important to know, first of all, what silicone is and how they are used in skincare and haircare products.

What Is Silicone?

Silicone – also called polysiloxane – is a synthetic polymer derived from the element silicon and oxygen atoms. Silicon is extracted from common sand with a variety of chemicals, most of which are recycled or inert (e.g. water). It’s been used in personal care products for more than 30 years, which comprises about 15% of all uses for silicones. It is now used in everything from breast implants and beauty blenders to products found at Home Depot. Because it repels water, it’s useful for projects that require a waterproofing substance. Two types of silicone are commonly used; water soluble and non-water soluble.

Silicones In Skincare

If you look at the labels on most skincare and cosmetic products, you’ll find ingredients like Dimethicone, Cyclomethicone, Cyclopentasiloxane and Cyclohexasiloxane. These silicones are not water soluble. Silicones are popular in primers for their ability to leave skin feeling silky smooth, and they tend to reflect light. Most recently, polymers like Polybutene and Polyisobutene may appear on your product labels. It’s becoming more difficult to identify silicones in beauty products. For those of us who are looking to avoid synthetics, it’s becoming almost impossible to avoid them in skincare products. That, in and of itself, is troubling. Consumers should be able to choose whether or not to use products containing synthetic polymers that don’t benefit the skin in any long-lasting way.

So what’s so wrong about silicone in skincare? The answer often depends on your skin type and personal preferences. The moisture-trapping nature of silicone may mean that it also traps other substances (like dirt and oils) that may cause breakouts. And while everyone loves smooth-looking skin, it’s a short-lived effect rather than the result of a product’s impact on the skin. Their water-repellent nature can also make them more difficult to remove, which requires more intense cleansing at the end of the day.

We’ve decided to avoid using silicones in our Whole Earth Body Actives Vitamin C Face Cream. Instead, we’ve incorporated isoflavones derived from bamboo to smooth and enhance the skin’s appearance.

Silicones in Haircare

At first, the benefits of using silicones in haircare may seem obvious. They serve to smooth our frizzines, and who doesn’t love that? However, the water-repellent nature of most silicones can cause them to accumulate in their hair, making it heavy. Removing this product from their hair then requires the use of a deep-cleaning (e.g. harsher) clarifying shampoo. For dry, curly hair, this can do more harm than good. For many, the use of a nourishing oil like coconut or argan would be preferable to smoothing a synthetic all over the hair. Recently, some products formulate with water-soluble silicones that are easier to wash out. Examples are hydrolyzed wheat protein and ingredients that begin with PEG.

Finally, there’s a question of sustainability and eco-friendliness with this ingredient. Petroleum by-products are used to create silicones, which begs the question: do we want such a by-product in our skincare and haircare products? There may also be a question of bioaccumulation in the environment and what this means for wildlife. Given the furor over the use of plastic beads, it’s something to think about.
