1. Physical properties: water and milk (usually referred to as lotion, such as cosmetics lotion or lotion like food) are different in physical properties. Water is a pure liquid, while lotion is a mixture of water and oil (or other water-insoluble ingredients), and they are kept in a stable dispersion state through emulsifiers.
2. Mixing effect: It is physically feasible to directly mix water and lotion in a bottle, but the stability and effect after mixing depend on the composition and formula of lotion. Some lotion may lose their original stability due to the addition of water, resulting in delamination or deterioration.
3. Application considerations: In the cosmetics or food field, it is generally not recommended to mix water and lotion directly, because this may affect the texture, shelf life and use effect of the product. If it is necessary to adjust the concentration or dilution of lotion, it is better to follow the product instructions or professional advice.
Water and milk can be mixed in one bottle, but the effect and impact need to be evaluated based on specific circumstances.
