Oil Additives in MP Soap

[SWashington]

Hi. I’m very new to this. I would like to use natural colorants in melt and pour soap but they are made by cold infusions in oil. But I have learned adding oil to MP bases would essentially ruin the base if it’s anything more than a tsp per lb. However I have learned that you can be a little more generous with fragrance oils adding almost a TBS per lb. Is there a reason why you can add more fragrance oils without ruining the base vs regular oils. Also is making cold infusions with fragrance oils a bad idea?

Don't go over 1 TBSP per lb of M&P base.

Thank you. Is this for any oil or just fragrance oils? Because I’m reading a teaspoon of regular oil per pound. And a tablespoon of natural fragrance oils per pound.

This is for oils and butters, not FOs. For FOs, follow the suggested usage rate by suppliers.

The composition of fragrance oils and essential oils are very different from the fatty acid profiles in oils used for making soap. Hopefully @DeeAnna or someone can jump in or post a link to explain the difference.

From Google AI:
In soap making, "fragrance oil" refers to the concentrated scent used to add aroma, while "carrier oils" are the base oils like olive oil or coconut oil that are used to create the soap itself, essentially acting as a vehicle to disperse the fragrance oil throughout the soap mixture; fragrance oils are composed of synthetic or natural aromatic compounds, while carrier oils are typically fatty acids derived from plants, each serving a distinct function in the soap-making process.
