Simple instructions on how to use our various toiletry concentrates.
We currently have the following concentrated bases which require the addition of water and in some cases common salt (salt solution) to turn them into finished products. They are as follows:-

Foam Bath/Shower Gel Concentrate (Liquid Crystal)

This is a clear surfactant-based concentrate which gives exceptional clarity and dilutes at a ratio of 3:1 (3 parts clean water to 1 part base) and then thickens with the addition of a little common salt (in solution). It takes water soluble colours very well with no particular ones to avoid and fragrances/essential oils at max 1% in final volume.

Instructions:

Weigh out the desired amount of concentrate into a suitable container or large bowl. Add fragrance or essential oil/s at equivalent of 1% in final intended volume (4% in concentrate if diluting to maximum) and stir or gently whisk to fully incorporate. Whilst weighing the product in container add clean water (distilled/deionised or purified if preferred) at up to 3:1 dilution, stirring continuously but not too vigorously to avoid foaming. If the diluted viscosity is less than desirable add salt solution (common table salt dissolved 25% in water) a little at a time, stirring continuously, until desired viscosity is achieved.
Finally add water soluble colour (in diluted form) as required. Leave to stand until clear and bubble-free.
Bottle as required.
Hints: Recommended dilution ratios for this product can vary to give 'economy' to 'luxury' variants. They are as follows... Luxury 2:1. Economy 4:1. Liquid Pearliser may be added, typically at 1-2% of final volume. Add before dilution for best results. If you add too much salt, this product may become cloudy. To rescue this, simply add more clean water until clear again, then add more base until dilution ratio is corrected and consistency is correct.

Liquid Hand Soap Base 105 S. Palm-Free

This bases is made with organic certified oils that gives good clarity and can be diluted at up to 2:1 (2 parts water to 1 part concentrate) if a full-strength product is not required. To thicken to a suitable viscosity for hand-pumping it should have a solution of 25% salt, preferably in deionised water added with the product warmed to aprox 30-35 degC, pouring the salt solution into the stirring vortex. Use typically 4% of salt solution to product volume (if undiluted), mixing continuously until thickened. It takes essential/fragrance oils at a recommended 0.5% (but our experience suggests 1% is a maximum) of final volume and takes most water soluble dyes very well. When diluted, the %age of salt solution required to thicken will need to be increased.
Instructions: (Although these are manufacturers instructions, our experience with this product suggests it can be thickened at room temperature, negating the need for heat. Tap water can also be used instead of purified forms)
Weigh product into a suitable vessel for heating (can be gently heated on a hob in a thick-bottomed pan if you don't have alternative equipment). Add deionised or distilled water, if desired, at up to 2:1 (2 parts deionised water to 1 part product) stirring until completely combined. Warm the product to 30-35 degC before adding essential oil/s (if desired) adding them to a recommended typical 0.5% or maximum 1%, stirring thoroughly to ensure complete dispersion.
Meanwhile make up a warm solution consisting of 25% salt in deionised or distilled water (i.e.25g of salt dissolved in 75g of water).
Then... whilst stirring the product, add the salt solution to the stirring vortex a little at a time, stirring constantly until it starts to thicken. The thickening process takes a little time so be careful NOT to add too much salt solution as it cannot be removed. As a guide use no more than 4% of the salt solution by volume to reach a satisfactory viscosity, although the more dilute your product, the more salt solution will be required.
If adding colour, use suitable alkali-tolerant water soluble dye and add to finished product.
Hint... Keep stirring gently but constantly to avoid incorporating air bubbles, which are slow to rise out once the product is thickened.
Bottle as required.
Important. This base do not contain any additional preservative. It relies on naturally high pH value and salt to act as suitable preservative. In dilutions of over 1:1 it may be necessary to add a suitable additional preservative if this product is to undergo successful challenge-testing for safety assessment.
Note: If you want to maintain Organic Status for the final product in entirity you should use pure salt that does not contain caking agents. If you cannot obtain this in suitable form (fine granular, like table salt), you may have to use a coarse grade or even tablets of salt.
Bottles, jars and dispensers are available here.
IMPORTANT NOTE... Certain colours fade out in some toiletry bases. This is not a problem with the base, but with the choice of colour. If you experience problems with colours changing or fading we can offer advice about alternative suitable colours.
