Instructions for making up products from concentrates
Simple instructions in how to use our various toiletry concentrates.
We currently have 3 types of concentrated bases which require the addition of water and in some cases common salt or salt solution to turn them into finished products. They are as follows:-
This base does not contain these surfactants and is therefore milder than other bases that do. It dilutes under normal conditions at a ratio of 2:1 (2 parts clean water to 1 part base). It has a recommended maximum 1% fragrance/essential oil (at final volume) and takes many water-soluble colours. Certain colours are not true in this base, in particular FCF Bright Blue and Carmoisine Red. These should be substituted for Patent Blue V and D&C Red 33.
These products are all virtually identical in the way they perform and so the same instructions apply to them all.
bases are 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 these products suggests they can be thickened at room temperature, negating the need to heat them. 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. These bases do not contain any additional preservative. They rely on naturally high pH values and salt to act as a 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.
