The guide
Nine ways to use castile soap
Can I use castile soap as baby wash?
Yes. It is unscented, so there is no perfume near baby's skin. Dilute it for the gentlest cleanse.
- Patch test first. Keep it away from the eyes.
- Mix 1 part soap with 10 parts water.
- Newborns or reactive skin: ask your paediatrician first.
Can I use castile soap as body wash?
Yes. Use it straight from the bottle. A little goes a long way.
- Lather on wet skin.
- Rinse well.
- Moisturise after, because soap is naturally alkaline.
Can I use it as hand soap?
Yes. One pump, lather and rinse.
- Sulfate-free: a creamy lather, not big foam.
- Unscented, so the whole family can share it.
- Rinse well and moisturise if hands feel dry.
Is castile soap good for the face?
It can be, with care. It is clinically tested and dermatologist-approved for normal and sensitive skin.
- Use a small amount and avoid the eye area.
- Patch test first. Stop if irritation occurs.

Can I use castile soap for shaving?
Yes. It makes a creamy lather with no added fragrance, which is kinder on freshly shaved skin.

- Shave, then rinse well.
- Moisturise after. Patch test first if your skin is sensitive.
Can castile soap wash hair?
Many people use castile soap on hair, and it can be used on baby's hair too.
- It will not feel like shampoo packed with silicone oils.
- Soap is alkaline, so hair can feel different at first.
- It may not suit every hair type.
Can I use castile soap on my pet?

- No sulfates, synthetic fragrance, dyes or silicones.
- Avoid the eye area and rinse thoroughly.
- Ask your vet if your pet has skin problems.
Can castile soap clean baby toys, cots and seats?
Yes. It cleans without harsh detergent.
- Use a small amount on a damp cloth.

- Use a small amount on a damp cloth or sponge.
- Rinse with clean water.
- Never mix it with vinegar.
Ready to use. No mixing needed.
You do not need to dilute Yein&Young Castile Soap. Dilute it only when you want the gentlest cleanse for baby.
Straight from the bottle
Use it as it is for body, hands, face, hair, shaving, pets and home. A little goes a long way.
Diluted for baby
Mix 1 part soap with 10 parts water. For example, 10ml of soap with 100ml of water.
Mix a fresh batch
If you dilute it, mix only what you need. Diluted soap has no preservatives.
Never with vinegar
Acids make castile soap curdle and stop working.

Why unscented
Babies don't need fragrance
Fragrance does not clean anything. It is added for the adult nose, not for baby's skin. So we left it out completely, and that makes one bottle safe to share across the whole family.
It can irritate
Fragrance is one of the most common causes of skin reactions. Baby skin is thin and delicate.
It hides the list
On a label, the single word "fragrance" can stand for many ingredients.
Baby smells like baby
Newborns learn their parents' natural scent. Many parents like to keep it that way.
It adds nothing
A good wash needs soap and water, not perfume.
Unscented or fragrance-free? Some "unscented" products add a masking fragrance to cover smells. Yein&Young adds no fragrance of any kind.
What we left out, and why
Every ingredient is a choice. These are the ones we chose not to use.
No fragrance
It adds scent, not cleaning. It is a common cause of skin reactions.
No sulfates
They make big foam, but can strip the natural oils from delicate skin.
No colour
Dye does nothing for skin. It only makes the bottle look pretty.
No preservatives
Fewer added ingredients means fewer things that can irritate delicate skin.
No silicone oils
They coat skin and hair but do not clean. Some break down slowly in nature.
No synthetic detergents
Cleaning comes from plant-oil soap, not lab-made foaming agents.

Kind to nature
Good for your home. Good for the river.
Everything you wash off goes down the drain, into rivers and out to the sea. Yein&Young is made to go back to nature.
100% biodegradable
Plant oils that break down naturally.
Nature-bound
From olive, coconut and castor oil, and back to nature.
Reef and river safe
No sulfates, dyes, silicones or synthetic fragrance in the water.
Glass, not plastic
One bottle does the job of several products, and it is packed in glass.
Five bottles or one?
Fewer bottles means less clutter in the bathroom, less to buy and less to throw away. Try 230ml for RM55, or get 1L for RM145 if the whole family uses it.
What is in the bottle
Organic olive oil
Soft and conditioning. The classic oil in castile soap.
Organic coconut oil
Gives the cleansing power and a light, creamy lather.
Castor oil
Adds a smooth, creamy feel to the lather.
No added fragrance. No colour. No sulfates. No preservatives.

Read the label: how it compares
Based on common ingredients in typical mass-market washes. Always read each label.
Good to know before you buy
Soap is alkaline
That is why we say rinse well and moisturise after.
Light lather
Expect a creamy, gentle lather, not big foam.
Hair may feel different
It will not feel the same as conventional shampoo that is packed with silicone oils.
Not a medical treatment
For skin conditions, see your doctor. It is clinically tested and suitable for sensitive skin.

What customers say
It cleanses oily skin without drying out my skin.Jerral K., Organic Liquid Castile Soap
I started using the Organic Liquid Castile Soap (3 times a week) and amazingly, it did not trigger any flaring.Jenjen J. Individual results vary.
I really enjoy using this soap. It lathers up well compared to other organic and castile soaps. I've noticed my skin has been extra soft and moisturised lately even without lotion (even my knees, elbows, and small patches of eczema on my hands). For an impulse purchase, it's brought a lot of benefits. Will definitely repurchase in the future!Aiqaira, Yein&Young customer
Doesn't dry out skin compared to other soap. As some one that has sensitive skin. This liquid soap does not make my skin itchy after a shower. Just wished that I encounter this soap earlier. No complains, I am sticking with this soap from now on.J****N
