Biobased 1,3 Propanediol Benefits for Hair Softness, Shine and Health

Biobased 1,3 propanediol benefits for hair have been demonstrated in consumer studies.

ZemeaⓇ, also known as 1, 3 propanediol, is a biobased (i.e. plant-based) glycol produced by a proprietary fermentation process of glucose derived from corn. This unique ingredient can be used as a natural alternative to petroleum-derived glycols in hair products. With its humectant, water drawing properties, it works as an excellent moisturizer for the hair.  In consumer tests, it has received higher performance ratings compared to petroleum-based compounds.  Overall 1,3 propanediol benefits for hair also include the ability to fight dandruff and improve the look and feel of the strands.

Environmental and Hair Benefits of 1,3 Propanediol as a Petroleum Alternative

Glycols, which are conventionally sourced from petroleum, are synthetic humectants. Examples include compounds such as:

  • Propylene glycol (1,2 propanediol)
  • Butylene glycol (1,3 or 1,4 butanediol)
  • Glycerin

They are common to hair and skin products due to their moisturizing, emulsifying, preservative and antimicrobial properties.

Although glycols from petroleum are not considered hazardous, many consumers prefer more natural, eco-friendly alternatives.

Most products made for both consumers as well as industrial applications are manufactured with non-renewable petrochemicals which are finite in availability and thus unsustainable.

By contrast, ZemeaⓇ, 1,3 propanediol is made from corn, a resource which can easily be planted and renewed (1).

Zemea 1,3 propanediol for hair care is derived from corn

Zemea 1,3 propanediol for hair care is derived from corn.

In the production of ZemeaⓇ, the corn is first harvested and dried before it undergoes a wet-milling process from which glucose is then derived.

Next, through a proprietary fermentation process, a patented micro-organism is used to turn glucose into 1,3 propanediol under very specific conditions and temperatures.

Finally, during the refining phase, the micro-organism is deactivated and removed along with waste byproducts and water to achieve a 99.7% purity state.

Not only does 1,3 Propanediol (or ZemeaⓇ) come from corn, but is also certified to be 100 percent biobased by the USDA BioPreferred program, an initiative intended to reduce the reliance on petroleum by the United States by helping to expand and develop markets for products that are biobased.

It has also received its stamp of approval by Ecocert, an organic certification organization in Europe.

ZemeaⓇ is also certified by the Natural Products Association an organization in Washington DC which represents the interests of natural product manufacturers and suppliers. In fact, it is the first ever bio-based alternative to glycol made available to the world which has received certification by the NPA.

Biobased 1,3 propanediol is considered to be “the greener alternative” due to its sustainable manufacturing processes that generate reduced greenhouse gas emissions by 56%. Compared to petroleum-based 1,3 propanediol, it uses 42% less non-renewable energy.

1,3 propanediol benefits for hair make it an excellent choice for products like shampoos and conditioners to moisturize dry tresses and improve their overall texture and appearance.

1,3 Propanediol Benefits for Hair and Scalp in Dandruff Treatments

The manufacturers of ZemeaⓇ, Dupont, Tate, and Lyle published a study on the use of their biobased propanediol as a rather groundbreaking ingredient which can enhance the performance of dandruff treatment products (2).

Since the 1960’s, the conventionally used active ingredient for medicated dandruff shampoos has been zinc pyrithione (ZPT). It possesses specialized antimicrobial properties against a dandruff-causing fungus known as M. globosa.

Various concentrations of ZemeaⓇ were included in base treatment formulations prepared with zinc pyrithione. These included

  • 0% (control)
  • 1%
  • 2%
  • 3%
  • 4%

The researchers then cultivated in-vitro populations of the M.globosa fungus, allowing it to proliferate on a Sabourads dextrose medium, for a period of seven days at 20-25 degrees Celcius.

They harvested and exposed the fungus to 0.1mL of the ZemeaⓇ and ZPT combination, measuring the mortality rates that resulted.

The experimenters found that the 4% ZemiaⓇ concentration prepared with 2.5% zinc pyrithione increased the fungal mortality by 90% within a 24 hour period.

ZemiaⓇ was thus shown to have a synergistic relationship with ZPT, helping to greatly enhance its effectiveness against dandruff.

This study illustrates the potential for biobased 1,3 propanediol as a viable addition to dandruff shampoos, which could vastly improve upon the existing performance levels of these products.

1, 3 Propanediol Uses for Hair Loss as a Fungicide

The dandruff fighting capabilities of 1 ,3 propanediol benefits for hair are not just valuable for the sake of eliminating embarrassing and unsightly white flakes, but also for preventing hair loss.

Dandruff tends to elicit itchiness on the scalp. Constant scratching can erode the skin and create open areas which can act as an entrance point for other microbes and foreign matter, contributing to inflammation and the subsequent risk of damaging the hair follicles.

The itching from dandruff alone may lead to temporary forms of hair loss. But for individuals with androgenic alopecia, inflammation can worsen the shedding and thinning they are already experiencing.

1,3 propanediol benefits for hair may greatly improve the effectiveness of dandruff shampoos. And in so doing, it can also support the prevention of hair loss.

1, 3 Propanediol Uses for Hair Product Formulations

Dupont, Tate, and Lyle have also conducted studies of ZemeaⓇ 1,3 propanediol benefits for hair through applications in products such as shampoos and conditioners.

In one study, ZemeaⓇ shampoo was compared with other shampoos using propylene glycol, butylene glycol and glycerine on bleached hair(3).

The overall shampoo experience was divided into three stages: the application stage, the wet stage, and the dry stage. Subjects were asked to rate various criteria within each of the stages. ZemeaⓇ outperformed the other glycol shampoos on the following:

  • Ease of spreading during the application stage
  • Ease of wet combing (wet stage)
  • Feeling of cleanliness (wet stage)
  • Feeling of moisturization/conditioning (wet stage)
  • Dry combing (dry stage)
  • Feeling of moisturized, well-conditioned hair (dry stage)
  • Body fullness of hair (dry stage)

Plant Based 1, 3 Propanediol Benefits for Hair Moisturization

Researchers tested the hair moisturizing properties of ZemeaⓇ against propylene glycol, butylene glycol, and glycerin. The measurement used to represent moisturization performance was the “ratio of secondary evaporation” (3).

ZemeaⓇ scored higher than the petroleum-based glycols with this metric.

Improved Sensorial Attributes Using ZemeaⓇ 1,3 Propanediol for Hair Care

In another study, researchers were interested in seeing how consumers rated various sensorial attributes of ZemeaⓇ shampoo(3). These included:

  • Smoothness
  • Moisturizing feel
  • Lightness
  • Calmness
  • Softness
  • Sleekness

Likewise, they also asked consumers to rate a similar set of sensorial attributes for ZemeaⓇ leave-in conditioner.

For both the shampoo and conditioner, ZemeaⓇ earned higher ratings on the majority of sensory attributes, compared to the petroleum-based glycols.

Biobased 1,3 Propanediol Benefits for Hair Include Reduced Skin Irritation

Besides sensory and aesthetic properties, one of the other main advantages of ZemeaⓇ over petroleum-based glycols is that it does not irritate the skin. This was tested across multiple studies, using a method called the Draize Repeated Insult Patch Test (3).

Even when the concentration was increased up to 75%, ZemeaⓇ produced no irritation, signs of allergies, sensitization or fatigue of the skin. The control formulation also produced none of these symptoms.

However, the following percentages of subjects reported positive irritation at the following concentrations of propylene glycol:

  • 8.2% of subjects at 25% PG
  • 21.7% of subjects at 50% PG
  • 22.7% of subjects  at 75% PG

Through these findings, ZemeaⓇ has been deemed to have a low potential to irritate human skin.

Hair Benefits of 1,3 Propanediol Through Better Viscosity

A thick, rich viscosity (versus thin and watery) is a characteristic that is highly desired for the feel of hair shampoos.

Improving the thickness or viscosity of clear shampoo products using butylene glycol, propylene glycol, and glycerine is achieved by adding salt.

However, ZemeaⓇ has been shown to require 36% less salt compared to PG and 57% less salt compared to BG to achieve desirable viscosity levels(3).

Biobased 1,3 propanediol benefits for hair serves as an amazing example of a plant-derived compound that is surpassing the performance and demand for conventionally used chemicals in consumer products,  for hair care and beyond.
